1 BOILER INSTALLATION

1.1 Installation instructions.Immergas gas appliances must be installed exclusively by a professionally qualified and authorized technician.“VICTRIX 50” Range boilers can be installed outside or in a suitable room (heating station).Installation must meet the provisions of current standards and all applicable laws and regulations.

Important: ese boilers are designed exclusively for wall mounting.ese boilers must be used for room and similar heating.ese boilers are used to heat water to below boiling point at atmospheric pressure; therefore they must be connected to a heating system suitable for their performance and power.Before installing the appliance, ensure that it is delivered in perfect condition; if in doubt, contact the supplier im-mediately.Packaging materials (staples, nails, plastic bags, polystyrene foam, etc.) constitute a potential hazard and must be kept out of the reach of children.Keep all flammable objects (paper, rags, plastic, polystyrene, etc.) away from the appliance.In case of anomalies, faults or imperfect operation, the ap-pliance must be deactivated; call a qualified technician (e.g. the Immergas Technical Assistance Centre, which has specific technical expertise and original replacement parts).erefore do not carry out any operation or try to repair the appliance.Failure to observe the above implies personal responsibility and invalidates the warranty.• Installation rules: ese boilers are not designed to be

installed on plinths or floors (see figure), but exclusively for wall mounting. e wall surface must be smooth, without any protrusions or recesses enabling access to the rear part. Wall mounting of the boiler must guarantee stable and effective support for the generator. e plugs supplied standard with the appliance ensure adequate support only if inserted correctly (according to technical standards) in walls made of solid or cavity bricks. With walls made from bricks or cavity bricks, partitions with limited static properties, or in any case walls other than those indicated, a static test must be carried out to ensure adequate support. e boilers must be installed is such a way as to avoid any knocking or tampering.

1.2 Location of appliances.“VICTRIX 50” range boilers can be installed:- outdoors;

- in external rooms, also adjacent to the building being served, located on an uncovered area provided it is struc-turally separated and without common walls, or situated on the flat roof of the building served, always with common walls;

- in buildings intended for other uses or in rooms included within the building.

Such rooms must only be used for the heating systems.

Caution: Installation of appliances fed by gas at a density higher than 0.8 (LPG) is only allowed in above ground rooms, possibly communicating with rooms that are also above ground. In both cases the treadable surface must not have depressions or hollows able to create gas pockets deter-mining hazardous conditions.

Height of installation room.Installation of a single appliance: the room must be at least 2 m high.

Installation of several appliances in cascade (2 or 3 VICTRIX 50 appliances): considering the size of the boiler, the fume exhaust manifold (to be installed with 3% slope) and the water manifolds, the room must at least 2.30 m high.

e above heights enable correct installation of the appli-ances.

Arrangement of appliances in room.Single appliance: the distances between any external part of the boiler and the vertical and horizontal walls of the room must allow access to the adjustment, safety and control parts and also routine maintenance operations.

Several appliances not connected together but installed in the same room: there must be a distance of at least 200 mm be-tween several generators installed on the same wall, in order to allow access to the adjustment, safety and control parts and also routine maintenance of all the appliances installed.

Installation in cascade (2 or 3 VICTRIX 50 appliances): see instructions on page 18.

1.3 Airing and ventilation of installation rooms.e rooms must have one or more permanent ventilation openings on the external walls. e vents can be protected with metal grills, nets and/or anti-rain fins provided they do not reduce the net ventilation area.e ventilation openings must be executed and located so that they do not form gas pockets, irrespective of the conformation of the covering.

Ventilation for installation in external rooms. e mini-mum free surfaces, according to total heating power, must not be less than (the values are rounded off to the highest figure):a) rooms above ground

S > 510 cm 2 for 1 VICTRIX 50 single

S > 1020 cm 2 for 2 VICTRIX 50 appliances in cascade

S > 1530 cm 2 for 3 VICTRIX 50 appliances in cascade

b) basements and cellars up to -5 m from the reference level.

S > 765 cm 2 for 1 VICTRIX 50 single

S > 1530 cm 2 for 2 VICTRIX 50 appliances in cascade

S > 2290 cm 2 for 3 VICTRIX 50 appliances in cas-cade

c) cellars at a distance of between -5 m and -10 m from the reference level.

S > 5000 cm 2 for all configurations

In any case the net area of each opening must not be less than 100 cm 2.

Important: When installing appliances fed with gas at densities higher than 0.8 (LPG) in external rooms, above ground, at least 2/3 of the ventilation surface must be flush with the treadable level, with a min. height of 0.2 m.e ventilation openings must be at least 2 m away from hollows, depressions or openings communicating with rooms located below the treadable level or drainage ducts, for heat-ing powers of not more than 116 kW and 4.5 m for higher heating powers.

Ventilation for installation in buildings also intended for other uses or in rooms located within the building served. e ventilation area must not be less than 3000 cm 2 in case of natural gas and not less than 5000 cm 2 for LPG.

Fume exhaust.e “VICTRIX 50” boiler must be connected to an efficient single flue.

N.B.: With single installation, the “VICTRIX 50” can be connected to the Ø 80 mm flexible ducting system for condensing boilers (point 1.11 of this manual).

Alternatively, the “VICTRIX 50” boiler can exhaust the fumes directly outside, using the special fume exhaust kits described in this manual (points 1.9 and 1.10).

When installing “VICTRIX 50” boilers in cascade, the fume exhaust manifold (supplied by Immergas) must be connected to an efficient flue of suitable size (see page 18).

1.4 External installation.e “VICTRIX 50” boiler has IPX5D protection rating and can also be installed outside, without requiring additional protection.Important: All the optional kits that can be connected to the boiler must be protected according to their electrical protection rating.

1.5 Antifreeze protection.Min. temperature -5°C. e boiler comes standard with an antifreeze function that switches on the pump and burner when the system water temperature in the boiler falls below 3°C.However, the antifreeze function is guaranteed only if:- the boiler is correctly connected to the gas and electricity

supply circuits;

- the main switch is on;

- the boiler is not in ignition “block”;

- the main boiler components are efficient.

In these conditions the boiler is protected against freezing to a room temperature of -5°C.

Min. temperature -15°C. If the boiler is installed in a place where the temperature falls below -5°C and in the event there is no gas, or the boiler goes on ignition “block”, the appliance may freeze.To avoid the risk of freezing, comply with the following instructions:- Protect the heating circuit from freezing by introducing

a good quality antifreeze liquid, carefully following the manufacturer’s instructions regarding the amount required, and respect the minimum temperature required for pre-serving the system.

e materials the boilers are made from are resistant to ethylene and propylene glycol-based antifreeze liquids.For life and possible disposal, follow the supplier’s instruc-tions.- Protect the condensate drain trap and electronic card

against freezing by using an accessory suppliable by request (antifreeze kit) comprising two electric heating elements, the relevant cables and a control thermostat (carefully read the installation instructions contained in the accessory kit pack).

Boiler antifreezing protection is thus ensured only if:- the boiler is correctly connected to the electrical feed circuit;

- the main switch is on;

- the antifreezing kit components are efficient.

In these conditions the boiler is protected against freezing to a temperature of -15°C.e warranty does not cover damage due to interruption of the electrical power supply and non-compliance with that given on the previous page.

1.7 Connections.

Gas connection (Appliance category II 2H3+).Our boilers are built to operate on methane gas (G20) and LPG. Supply pipes must be the same as or larger than the 3/4” G boiler fitting.

N.B.: the gas supply pipe must be suitably dimensioned according to current regulations in order to guarantee correct gas flow to the boiler even in conditions of max. generator output and to guarantee appliance efficiency (technical data). e coupling system must conform to standards.Before connecting the gas line, ensure that all system gas pipelines are perfectly clean, and remove any residues that could impair boiler efficiency. Also make sure the gas supply corresponds to that for which the boiler is arranged (see boiler dataplate). If different, the appliance should be converted for operation with the specific type of gas required (see convert-ing appliance to another type of gas). e dynamic gas supply pressure must also be checked (methane or LPG) according to the type used in the boiler, as insufficient levels could reduce generator power and cause malfunctions.Ensure correct gas cock connection as shown in the assembly sequence given in the figure.A quick closing manual on/off valve with 90° turning and stopping at end of travel in the fully open/closed positions must be installed in a visible and easily accessible position on the gas supply piping outside the room where the appli-ance is installed.

Combustible gas quality. e appliance is designed to operate on gas free of impurities; otherwise it is advisable to fit special filters ahead of the appliance for restoring the purity of the gas.

Storage tanks (in case of supply from LPG depot).- New LPG storage tanks may contain residuals of inert

gases (nitrogen) that impoverish the mixture delivered to the appliance, causing anomalous operation.

- Due to the composition of the LPG mixture, layering of the mixture components may occur during the period of storage in the tanks. is can cause a variation in the heating power of the mixture delivered to the appliance, with subsequent change in its performance.

Water connection. Before making the water connections, all system piping must be carefully cleaned to remove any residues that could impair boiler efficiency. It is advisable to arrange a filter on the system for collection and separation of any impurities present in the system (sludge filter). In order to avoid scaling in the heating system, the provisions given in the regulations on water treatment in heating systems for civil use must be respected. Water connections must be made in a rational way using the connections on the boiler template. e boiler safety valve outlet must be connected to a drain funnel, which is present in the boiler but not installed, and in turn connected to a drainage pipe. Otherwise, the manufacturer declines any responsibility in case of flooding of the room if the drain valve cuts in.

Condensate drain. To drain the condensate produced by the appliance, it is necessary to connect to the drainage system by means of acid condensate resistant pipes having an internal diameter of at least 13 mm. e system connecting the appliance to the drainage system must be carried out in such a way as to prevent freezing of the liquid contained in it. Before appliance start-up, ensure that the condensate can be correctly removed. Also, comply with national and local regulations on discharging waste waters.

Electrical connection. e electrical system must be carried out in accordance with the law. e entire “VICTRIX 50” boiler has IPX5D protection rating. Electrical safety of the unit is guaranteed when correctly connected to an efficient earthing system as specified by current safety standards.

Important: Immergas S.p.A. declines any responsibility for damage or physical injury caused by failure to connect the boiler to an efficient earthing system or failure to observe the reference standards.

Also ensure that the electrical installation complies with the maximum absorbed power specified on the boiler dataplate. Boilers are supplied complete with an “X” type power cable without plug. e power cable must be connected to a 230V ±10% / 50Hz mains supply respecting the pole sequence L-N and earth connection , the mains power supply must also be equipped with a multi-pole circuit breaker with contact opening gap of at least 3 mm. e main switch must be installed in a marked and accessible position outside the rooms. When replacing the power supply cable, contact a qualified technician (e.g. the Immergas Technical Assistance Service). e power cable must be laid as shown.In case of mains fuse replacement on the connection terminal board, use a 2A quick-blow fuse. Do not use adapters, multiple sockets or extension leads for the main power supply to the appliance.If correct L-N polarity is not respected during connection, the boiler will not detect the flame and inhibits ignition.

Important: also, whenever L-N polarity is not respected, if the neutral is live with temporary residual voltage over 30V, the boiler could operate just the same (but only temporarily). Carry out voltage readings with suitable instruments; do not use a mains tester screwdriver.

ermoregulation controls (Optional).e boiler is arranged for application of the zone and cascade regulator, zone manager and external sensor.ese components are available as separate kits to the boiler and are supplied by request.Carefully read the use and assembly instructions contained in the accessory kit.

• e zone and cascade regulator is connected to the boiler by just 2 wires and is fed with 230 V, and allows the fol-lowing:

- management of a water circuit with 2 mixed zones (mixer valve); 1 direct zone; 1 generator unit and relevant cir-culating pumps;

- system self-diagnosis for displaying any boiler opera-tional anomalies;

- setting of two room temperature values: one for day

(comfort temperature) and one for night (lower tem-perature);

- management of domestic hot water temperature (in combination with a generator unit);

- management of boiler delivery temperature according to the external temperature;

- selecting the required function mode from the various possible alternatives for each single water circuit:

- permanent operation in comfort temp.;

- permanent operation in lower temp.;

- permanent operation in adjustable antifreeze temp.

• Zone manager. In addition to the functions described in the previous

point, the zone manager panel enables the user to control and have at hand all the important information regarding operation of the appliance and the heating system with the opportunity of easily intervening on the previously set parameters without having to go to the place where the zone and cascade regulator is installed. e climate chronothermostat incorporated in the remote panel ena-bles the system delivery temperature to be adjusted to the actual needs of the room being heated, in order to obtain the desired room temperature with extreme precision and therefore with evident saving in running costs. It also ena-bles the room temperature and actual external temperature (if the external sensor is present) to be displayed. e zone manager is fed directly by the cascade thermoregulator by means of 2 wires.

• External temperature sensor. is sensor can be connected directly to the boiler electrical system and allows the max. system delivery temperature to be automatically decreased when the outside temperature increases, in order to adjust the heat supplied to the system according to the change in external temperature. e external sensor always operates when connected regardless of the presence or type of thermoregulator used and can work in combination with both thermoregulators. The external sensor electrical connection must be made to the G and J terminals on the boiler X86 connection terminal board (see fig. page 8).

Zone and cascade regulator or On/Off chronothermostat (Optional) electrical connection. e following operations must be carried out after disconnecting the electrical power sup-ply. e possible thermostat or On/Off room chronothermo-stat must be connected to terminals “E” and “F” eliminating jumper X40 (see fig. page 8). Make sure that the On/Off thermostat contact is of the “clean” type, i.e. independent of the mains supply, otherwise the electronic adjustment card would be damaged. e possible zone and cascade regula-tor must be connected by means of terminals 37 and 38 to terminals “M” and “O” on terminal board X86 (in boiler) respecting the polarity, (see fig. page 8) however, connection with wrong polarity will not damage the thermoregulator but prevents its operation.

Important: if the zone and cascade regulator is used, two separate lines must be arranged in accordance with current regulations on electrical systems. Boiler pipes must never be used to earth the electric or telephone lines. erefore, ensure that this does not occur, before making the boiler electrical connections.

Installation with system operating at low temperature. e boiler can directly feed a low temperature system, varying the max. delivery temperature of the generator and setting a value of between 20 and 85 °C. To vary the generator max. delivery temperature, modify the generator max. delivery temperature of parameter No. 4 according to the “parameter mode” procedure.In this mode it is advisable to include a safety in series with the boiler circulating pump, formed of a thermostat having a limit temperature of 55 °C. e thermostat must be po-sitioned on the system delivery pipe at more than 2 metres from the boiler.

1.8 Air intake and fume exhaust terminal installationImmergas supplies various solutions, separately from the boilers, for the installation of air intake and fume exhaust terminals without which the boiler cannot work.

Important: the boiler must be installed exclusively with an original Immergas “Green Range” air intake and fume extraction system in plastic, as required by current regula-tions. is system is identifiable by a special distinctive marking giving the note: “for condensing boilers only”.

• Resistance factors and equivalent lengths Each fume ex-haust system component has a Resistance Factor obtained from experimental testing and specified in the table below. e resistance factor for individual components does not depend on the type of boiler on which they are installed and is a dimensional value. It depends on the temperature of fluids flowing through the ducts and therefore varies according to applications for air intake or fume exhaust. Each single component has a resistance corresponding to a certain length in metres of pipe of the same diameter; the so-called equivalent length. All boilers have an experimen-tally obtainable maximum Resistance Factor equal to 100. e maximum permissible resistance factor corresponds to the resistance measured with the maximum permissible pipe length with each type of Terminal Kit. is informa-tion enables calculations for verifying the possibility of ex-ecuting various configurations of fume exhaust systems.

Positioning of double lip seals. For correct positioning of lip seals on elbows and extensions, follow the assembly direction given in the figure.

1.9 Boiler installation with “C” type configuration“VICTRIX 50” boilers leave the factory with “B 23” type configuration (open chamber and forced draught), to change the configuration to “C” type (sealed chamber and forced draught), remove the Ø 80 adapter, the bracket and gasket present on the boiler cover.

Horizontal intake kits Ø 80/125.Kit assembly: fit the Ø 80/125 adapter (1) up to the stop on the central hole of the boiler. Slide the gasket (2) along the adapter (1) up to the special groove, then fix it to the cover by means of the previously removed sheet plate (3). Fit the male end (smooth) of the bend (4) up to the stop on the adapter (1). Fit the male end (smooth) of the Ø 80/125 concentric terminal pipe (5) up to the stop on the female end of the bend (4) (with lip seals), making sure that the relevant internal (6) and external (7) rings are fitted; this will ensure hold and joining of the elements making up the kit.

• Coupling extension pipes and concentric elbows Ø 80/125. To install possible coupling extensions with other elements of the boiler assembly, proceed as follows: fit the male end (smooth) of the concentric pipe or elbow up to the stop on the female end (with lip seals) of the previously installed element; this will ensure hold and correct joining of the elements.

e Ø 80/125 kit can be installed with the rear, right side, left side and front outlet.

• Extensions for horizontal kit. e horizontal intake-exhaust kit Ø 80/125 can be extended up to a max. horizontal distance of 14 m, including the grill terminal and excluding the concentric bend leaving the boiler. is configuration corresponds to a resistance factor of 100. In this case special extensions must be requested.

N.B.: when installing the ducts a min. slope of 3% must be maintained and a section clamp with pin must be installed every 3 metres.

• External grill. N.B.: for safety purposes, do not even temporarily obstruct the boiler intake/exhaust terminal.

Vertical kit with aluminium tile Ø 80/125.Kit assembly: Fit the Ø 80/125 adapter (1) up to the stop on the central hole of the boiler. Slide the gasket (2) along the adapter (1) up to the special groove, then fix it to the cover by means of the previously removed sheet plate (3). Imitation aluminium tile installation: replace the tile with the aluminium sheet (5), shaping it to ensure that rainwater runs off. Position the fixed half-shell (6) on the aluminium tile and insert the intake/exhaust terminal (7). Fit the male end (smooth) of the Ø 80/125 concentric terminal up to the stop on the female end of the adapter (1) (with lip seals), making sure that the ring (4) is already fitted; this will ensure hold and joining of the elements making up the kit.

• Coupling extension pipe fittings and concentric elbows Ø 80/125. To install possible coupling extensions with other elements of the fume exhaust system, proceed as follows: fit the male end (smooth) of the concentric pipe or elbow down the stop on the female end (with lip seals) of the previously installed element; this will ensure hold and correct joining of the elements.

Important: if the exhaust terminal and/or concentric extension pipe needs shortening, consider that the internal conduit must always protrude by 5 mm with respect to the external conduit.

is particular terminal enables fume exhaust and air intake necessary for combustion, in a vertical direction.

e Ø 80/125 vertical kit with aluminium tile enables instal-lation on terraces and roofs with maximum slopes of between 25% and 45% (24°), the height between the terminal cap and half-shell (260 mm) must always be respected.

e vertical kit with this configuration can be extended to a max. vertical length of 18 m, including the terminal. is configuration corresponds to a resistance factor of 100. In this case special coupling extensions must be requested.

1.10 Installing “B23 ” type single boiler with open chamber and forced draught.

“VICTRIX 50” boilers leave the factory in “B23“ type con-figuration (open chamber and forced draught).Air is drawn directly from the place where the boiler is installed, by means of special slots obtained in the back of the appliance and fumes are exhausted into a single flue or directly to the outside. In this configuration the boiler is classified B23 type.With this configuration:- air is drawn directly from the place where the boiler is

installed;

- the fume exhaust must be connected to its own single flue or ducted directly to the outside.

1.11 Existing flue ducting.Ducting is an operation through which, within the context of restructuring a system and with the introduction of one or more special ducts, a new system is executed for evacuating the fumes of a gas appliance, starting from an existing flue (or a chimney) or a technical hole. Ducting requires using conduits declared suitable for the purpose by the manufac-turer, following the installation and operation instructions provided by the manufacturer, and the requirements of the standard.

Immergas Ø 80 mm ducting system. e “Green Range” Ø 80 flexible ducting system must only be used with Immergas condensing boilers.In any case, ducting operations must respect the provisions contained in the standard and in current technical regulations; in particular, the declaration of conformity must be compiled at the end of work and on commissioning of the ducted system. e instructions in the project or technical report must likewise be followed, in cases provided for by the standard and current technical regulations. e system or components of the system have a technical life complying with current standards, provided that:- it is used in average atmospheric and environmental condi-

tions, according to current regulations (absence of fumes, dusts or gases that can alter the normal thermophysical or chemical conditions; existence of temperatures coming within the standard range of daily variation, etc.).

- Installation and maintenance are performed according to the manufacturer’s instructions and the provisions of cur-rent regulations.

- e max. possible length of the Ø 80 flexible ducting verti-cal section is equal to 30 m. is length is obtained consid-ering the complete exhaust terminal, 1m of Ø 80 pipe in exhaust, two 90° Ø 80 bends at boiler outlet for connecting to the ducting system and two direction changes of the flexible tube inside the flue/technical hole.

1.12 Fume exhaust with boiler in cascade.“VICTRIX 50” boilers installed in cascade and composed of 2 or 3 generators, can be joined by manifold to a single flue going the chimney.Immergas supplies a suitable and original fume exhaust system separately from the boilers.However, for correct assembly of the kit the following indica-tions must be taken into consideration.- there must be a distance of 800 mm between generators

(either 2 or 3) (see figure above);

- the generators must be arranged on the same horizontal line;

- the Ø 125 exhaust manifold must have a min. slope of 3%;

- the drain for condensate produced by the appliances must be run into a drainage system;

- the fume exhaust manifold kit cannot be installed on the outside (the tubing must not be exposed to UV sun-light).

N.B.: check and if necessary adjust the heating power of each single appliance (see adjustments page 40).

Kit assembly: Fit the various sections with fume damper (1-2 and 3) up to the stop on the central hole of each single boiler. Fit the various bends with inspection (4-5 and 6) on the relevant sections with damper from the shortest to longest so that the bend closest to the flue is the highest (see figure above), then fit pipe (7) on bend (4). Cut pipes (8) and (9) to size in order to respect the centre distance of 800 mm between the boilers (see figure above).Install pipe (8) on bend (5) and then fit everything on pipe (7).Install pipe (9) on bend (6) and then fit everything on pipe (8).Cut pipe (12) to size for correct connection between the flue and pipe (9).Fit pipe (10) up to the stop on pipe (7). Fit the condensate drain section with trap (11) up to the stop on pipe (10).

1.13 System filling.After the boiler is connected, proceed with filling the system. Filling must be done slowly to ensure the release of air bub-bles in the water via the boiler and heating system vents.e boiler is equipped with an automatic air valve located on the circulating pump. Check that the cap is loosened. Open the relief valves on the radiators. Close the relief valves only when water comes out.

N.B.: During this operation, start the circulating pump at intervals by means of the main switch on the control panel. Vent the circulating pump by unscrewing the front cap and keeping the motor running. Tighten the cap on completion.

N.B.: e “VICTRIX 50” boiler does not have an expansion tank on the system. A closed expansion tank must be installed to guarantee correct boiler operation. e expansion tank must comply with current regulations in the country of installation. e dimensions of the expansion tank depend on the data relevant to the heating system; install a tank with capacity meeting the requirements of current regulations.

1.14 Filling condensate collection trap.On first lighting of the boiler fumes may come out the condensate drain; after a few minutes’ operation check that fumes no longer come out. is means that the trap is filled with condensate to the correct level preventing the passage of fumes.

1.15 Gas system start-up.To start up the system proceed as follows:

- open windows and doors;

- avoid the presence of sparks or naked flames;

- vent all air from pipes;

- check gas supply tightness with the boiler gas ON/OFF cock closed, no gas flow must be indicated on the meter for 10 minutes;

1.16 Boiler start-up (lighting).For issue of the Declaration of Conformity provided for by Italian Law, the following must be done for boiler start-up:- check the gas supply circuit tightness with the 0n/Off valve

closed and subsequently open with gas valve closed; no gas flow must be indicated on the meter for 30 minutes;

- ensure that the type of gas used corresponds to that for which the boiler is arranged;

- switch on the boiler and ensure correct ignition;

- make sure that the gas flow and pressure values correspond to those given in the manual (see page 43);

- check intervention of the safety device in case of no gas and check activation time;

- check activation of the main switch ahead of the boiler and on the unit;

- check that the concentric intake/exhaust terminal (if fitted) is not blocked.

If any of these checks gives negative results, do not start the boiler.N.B.: the boiler preliminary check must be carried out by a qualified technician. e boiler warranty is valid as of the date of testing.e test and warranty certificate is issued to the user.

1.17 Circulating pump.“VICTRIX 50” Range boilers are supplied with a built-in circulating pump with 3-position electric speed control. e boiler does not operate correctly with the circulating pump on first speed. To ensure optimal boiler operation, in case of new systems (single pipe and modul) use the circulating pump at maximum speed. e circulating pump is already fitted with a capacitor.

Pump release. If, after a prolonged period of inactivity, the circulating pump is blocked, unscrew the front cap and turn the motor shaft using a screwdriver. Take great care during this operation to avoid damage to the motor.

2 OPERATION AND MAINTENANCE INSTRUCTIONS

2.1 Cleaning and maintenance.Important: the user must have at least one servicing of the heating system and one combustion check (“flue test”) carried out every year.is ensures optimal boiler safety, performance and opera-tion over time.We recommend stipulating a yearly cleaning and mainte-nance contract with your area technician.

2.2 Installation room airing and ventilation.See the chapter “Installation room airing and ventilation” on page 4 of this manual.

2.3 General instructions.Use of the boiler by unskilled persons or children is pro-hibited.For safety purposes, ensure that the concentric air intake/flue exhaust terminal (if fitted) is not blocked.If temporary shutdown of the boiler is required, proceed as follows:a) drain the heating system if antifreeze is not used;

b) turn off all electrical, water and gas supplies.

N.B.: In case of boiler maintenance operations not involving the closing of one or both system on/off cocks (34 see page 25), the boiler must be shut down.

In case of work or maintenance to structures located in the vicinity of ducting or fume exhaust devices and relative ac-cessories, switch off the appliance and at the end of work have a qualified technician check the efficiency of the duct-ing or devices.Never clean the appliance or its parts with easily flammable substances.Never leave containers or flammable substances in the same room as the appliance.

• Caution: the use of components involving use of electrical power requires observance of some fundamental rules:

- do not touch the appliance with wet or moist parts of the body; do not touch when barefoot;

- do not pull electrical cables; - the appliance power cable must not be replaced by the

user; - in the event of damage to the cable, switch off the ap-

pliance and contact exclusively qualified personnel for replacement;

- if the appliance is not used for a certain period, discon-nect the main power switch.

In operational phase, the 4-figure display indicates the func-tion mode (by means of the first 2 figures on the left) and the boiler delivery temperature (by means of the other two figures on the right).

E.g. if these values are shown on the display it means that the appliance is operating on heat-ing with a delivery temperature of 60 °C.

e boiler function modes are given below:0 Stand-by, no operation demand

1 Preventilation

2 Burner ignition

3 Burner lit (system heating)

4 Burner lit (domestic hot water)

5 Fan control

6 Burner off

7 Pump post-circulation in heating mode

8 Pump post-circulation in domestic hot water mode

9 Burner off for one of the following reasons:- system delivery temperature (T1) higher than 95°C- system return temperature (T2) higher than 95°C- difference between system delivery and return tempera-

ture more than 40 °C- negative difference between system delivery and return

temperature- increase in delivery temperature too fast; the boiler stays

on stand-by for 10 min. and then restarts (3 re-ignition attempts, then the boiler goes on block)

Boiler shutdown. Turn off the main switch (1), turning it to “0”, and close the gas cock ahead of the appliance.Never leave the boiler switched on if not used for long periods.

2.5 Restoring heating system pressure.Periodically check the system water pressure.e boiler pressure gauge must give a value of not less than 0.5 bar.If the pressure is less than 0.5 bar (with the system cold) the water inside system must be restored.

N.B.: close the valve on completion.If the pressure reaches values of around 4 bar, there is risk of the safety valve being activated.In this case contact a professional technician for assistance.In the event of frequent pressure drops, contact qualified personnel for assistance to eliminate the possible system leakage.

2.6 Draining the system.To drain the boiler, use the special system drain connec-tion.Before draining, ensure that the filling cock is closed.

2.7 Antifreeze protection.e boiler comes standard with an antifreeze function that starts the pump and burner when the system water tem-perature inside the boiler falls below 3°C. e antifreeze function is guaranteed if the boiler is fully operative and not in “block” status, and is electrically fed. To avoid keeping the system operational in the event of prolonged absence it must be drained completely or antifreeze substances must be added to the heating system water. In appliances subject to frequent draining, the system must be refilled with suit-ably treated water to eliminate hardness that may cause the formation of scale.

2.8 Casing cleaning. Use damp cloths and neutral soap to clean the boiler casing. Never use abrasive or powder detergents.

2.9 Decommissioning.In the event of permanent boiler decommissioning, have professional personnel carry out the relevant procedures and ensure that the electrical, water and gas supply lines are disconnected.

3 BOILER STARTUP PRELIMINARY CHECK

To start up the boiler, proceed as follows:

- ensure that the declaration of conformity of installation is supplied with the appliance;

- check gas supply circuit tightness with the On/Off valves closed and subsequently open with gas valve closed; no gas flow must be indicated on the meter for 30 minutes;

- ensure that the type of gas used corresponds to that for which the boiler is arranged;

- check connection to a 230V-50Hz power mains, correct L-N polarity and the earthing connection.

- switch the boiler on and check correct ignition;- check the CO2 in the fumes at max. and min. output;- make sure the max., medium and min. gas flow and rele-

vant pressures correspond to those given in the manual on page 43;

- check activation of the safety device in the event of no gas, and the relative activation time;

- check intervention of the main switch located ahead of the boiler and on the unit;

- check the draught existing during regular boiler operation, by means of, for example, a vacuum meter placed directly at the fumes outlet;

- make sure there is no backflow of fumes in the room, even during the operation of possible electric fans;

- check that the intake and/or exhaust terminals are not blocked;

- check the intervention of all adjustment devices;- seal the gas flow regulation devices (if settings are modi-

fied);- check the tightness of water circuits;- check ventilation and/or aeration of the installation room

where provided.If any of the checks regarding safety give negative results, do not start the boiler.

N.B.: maintenance must be performed by a qualified technician (e.g. Immergas Technical Assistance Service).

- Smell of gas. Caused by leakage from gas circuit pipes. Check tightness of gas supply circuit.

- Irregular combustion or noisiness. is may be caused by a dirty burner, incorrect combustion parameters, intake-exhaust terminal not correctly installed. Clean the above components and ensure correct installation of the terminal, check correct setting of the gas valve (Off-Set setting) and correct percentage of CO2 in fumes.

- Trap clogged. is may be caused by dirt or combustion products inside. Check, by means of the condensate drain cap, that there are no residuals of material blocking the flow of condensate.

P 30

- Exchanger blocked. is may be caused by the trap being blocked. Check, by means of the condensate drain cap, that there are no residuals of material blocking the flow of condensate.

- Noise due to air in the system. Check opening of the special air valve cap (see fig. page 20). Ensure that system pressure and expansion tank precharge are within the set limits.

N.B.: e boiler must be shut down in case of boiler main-tenance involving the closing of one or both system on/off cocks (detail 34 page 25).

3.6 Converting the boiler to another type of gas.If the boiler has to be converted to a different gas type to that specified on the dataplate, request the relative conversion kit for quick and easy conversion.Boiler conversion must be carried out by a qualified techni-cian (e.g. Immergas Technical Assistance Service).To convert to another type of gas the following operations are required:- replace the nozzle located between the gas pipe and gas/air

mixing sleeve (detail 7 page 20);

- adjust maximum boiler heat output by changing the fan rpm (parameter 13 page 35);

- check the value of CO2 in fumes at max. power with respect to the table given on page 40;

- check the value of CO2 in fumes at min. power with respect to the table given on page 40;

- seal the gas flow regulation devices (if settings are changed);

- after completing conversion, apply the sticker, present in the conversion kit, near the dataplate. Using an indelible marker pen, cancel the data relative to the old type of gas.

ese adjustments must be made with reference to the type of gas used.

3.7 Checks following conversion to another type of gas.

After making sure that conversion was carried out with a nozzle of suitable diameter for the type of gas used and the settings are made at the correct pressure, check that:- the burner flame is not too high or low and is stable (does

not detach from burner);

- the pressure testers used for calibration are perfectly closed and there are no leaks in the gas circuit.

N.B.: All boiler adjustment operations must be carried out by a qualified technician (e.g. Immergas Assistance Service).Burner adjustment must be carried out using a differential digital type pressure gauge (with scale in tenths of mm or Pascal), connected to the gas valve (P3 - P2) outlet pressure point and on the pressure tester located above the sealed chamber (detail 15 page 20), respecting the pressure value given in the table on page 43 according to the type of gas for which the boiler is arranged.

3.8 Possible adjustments.• Rated heat output check.e boiler rated heat output is correlated to the length of the air intake and fume exhaust pipes. It decreases slightly in proportion to the increase in pipe length, therefore in case of max. pipe extension it is necessary to check the “∆p” values at the ends of the Venturi and gas pressure at the nozzle after at least 5 minutes of burner operation, when the air intake and exhaust gas temperatures have stabilized. If necessary, modify the values of parameter No. 13 “Fan max. rpm in heating”. Use differential manometers connected to the “∆p” pressure points on the Venturi and nozzle gas pressure as specified in

the chapter “Air/gas ratio adjustment”.is adjustment is not necessary during the initial check, as the boiler is factory-set with the correct air/gas ratio.However, it may be necessary during extraordinary main-tenance, with replacement of air and gas circuit compo-nents.After any adjustments:- ensure that the pressure testers used for calibration are

perfectly closed and there are no leaks in the gas circuit;

- seal the gas flow regulation devices (if settings are modi-fied).

3.9 Air/gas ratio adjustment.Min. CO2 setting.Switch the boiler on and run it at min. heat output pressing the “MODE” and “-” keys at the same time for 2 seconds; in this way the boiler is forced to minimum and the display shows the letter “L” followed by a 2-digit number. To have an exact value of CO2 in the fumes the technician must insert the sampling probe to the bottom of the chamber, then check that the CO2 value is that specified in the table on page 40, otherwise adjust the screw (3 page 41) (Off-Set regulator).

Max. CO2 setting.After min. CO2 adjustment, switch the boiler on and bring it to “chimney-sweep” phase pressing the “MODE” and “+” keys at the same time for 2 seconds; in this way the boiler is forced to maximum and the display shows the letter “H” followed by a 2-digit number. To have an exact value of CO2 in the fumes the technician must insert the sampling probe to the bottom of the chamber, then check that the CO2 value is that specified in the table on page 40, otherwise adjust the screw (12 page 41) (gas flow regulator).To increase the CO2 value turn the adjustment screw (12) anticlockwise or clockwise to decrease the value.

3.10 Combustion parameters check.For max. and min. heat output adjustment insert the dif-ferential manometer between P1 and P2 (see figure on page 34) for measuring the gas pressure. Switch the boiler to “Chimney-Sweep” phase by pressing the “MODE” and “+” keys at the same time for several seconds, check max. fan speed in order to obtain (with boiler on) the value given in the table on page 43; in case of parameter modification see the following chapters.

3.11 Rated heat output adjustmente “VICTRIX 50” boiler is produced with heat output set to maximum. erefore it is advisable not to change that setting.If the heating output has to be reduced, the value of para-meter No. 13 “Max. fan rpm in heating” must be modified, after entering the code reserved for the technician according to the procedure described on page 35.To check the adjusted heat output value compare the nozzle pressure value with that given in the table on page 43.

3.12 Heating min. output adjustment.If the min. heating output has to be modified, the value of parameter No. 17 “Min. fan rpm in heating” must be modified, after entering the code reserved for the technician according to the procedure described on page 35.To check the adjusted heat output value compare the nozzle pressure value with that given in the table on page 43.

3.13 Domestic circuit output adjustment.If the domestic output has to be modified, the value of para-meter No. 15 “Min. fan rpm in domestic” must be modified, after entering the code reserved for the technician according to the procedure described on page 35.To check the adjusted heat output value compare the nozzle pressure value with that given in the table on page 43.

3.14 Circulating pump function mode.Continuous circulating pump operation can be obtained by setting parameter No. 3 to the value 3, modifying according to the “parameter mode” procedure.

3.15 “Chimney-Sweep” function.When activated, this function forces the boiler at max. output for 15 minutes.In this mode all the adjustments are cut out and only the temperature safety thermostat and the limit thermostat remain active. To activate the “Chimney-Sweep” function press the “MODE” and “+” keys at the same time for two seconds. is function allows the technician to check the combustion parameters, the boiler is forced at maximum and the display shows the letter “H”. After the checks deactivate the function by pressing the “+” and “-” keys at the same time for 2 seconds.

3.16 Pump antiblock function.During the “Summer” phase the boiler is equipped with a function that starts the pump at least once every 24 hours for the duration of 10 seconds in order to reduce the risk of the pump becoming blocked due to prolonged inactivity.

3.17 Radiator antifreeze function.e boiler has a function that starts the pump when the system delivery water reaches 7 °C. If the system delivery water is below 3 °C, the boiler starts and runs until reach-ing 10 °C.

3.18 Max. delivery temperature value in heating.e generator max. delivery temperature can be changed by modifying parameter No. 4 “parameter mode”, setting a value of between 20 and 85 °C.

N.B.: the pressures given in the table indicate the differences in pressure at the ends of the mixer Venturi and measurable at the pressure points at the top of the sealed chamber (see pressure test 15 and 16 page 20). Adjustments must therefore be made with a digital differential pressure gauge having a scale in tenths of mm or Pascal.

e power data given in the table is obtained with intake/exhaust pipe of length 0.5 m. Gas flows refer to a heating power below a temperature of 15°C and at a pressure of 1013 mbar. Burner pressure values refer to the use of gas at 15°C.

3.20 Yearly appliance check and maintenance.e following checks and maintenance must be performed at least once a year.- Clean the flue side of the heat exchanger.

- Clean the main burner.

- Check correct ignition and operation.

- Check correct setting of burner in heating phase.

- Check correct operation of appliance control and adjust-ment devices and in particular:

- intervention of electrical main electrical switch on boiler;

- intervention of system adjustment sensors;

- Check tightness of gas circuit section between the applia-nce on/off valve (cock) and gas valve (cut out). Inserting a differential digital pressure gauge (with scale in tenths of mm or Pascal) in the pressure point ahead of the gas valve and subsequently closing the boiler on/off valve (cock) and closing the gas valve, after 5 minutes there must be no pressure variation on the gauge.

- Check intervention of the device against no gas ionization flame control;

- ensure intervention time is less than ten seconds.

- Visually check for water leaks or oxidation from/on con-nections and traces of condensate residuals inside the sealed chamber.

- By means of the condensate drain plug check for any residuals of material possibly blocking the flow of con-densate.

- Check contents of the condensate drain trap.

- Visually check that the water safety valve drain is not blocked.

- Ensure the system static pressure (with system cold and after refilling the system via the filler cock) is not less than 0.5 bar.

- Visually check that the safety and control devices have not been tampered with and/or short-circuited, in par-ticular:

- temperature safety thermostat;

- Check the state and integrity of the electrical system and in particular:

- electrical power cables must be inside the whipping;

- there must be no traces of blackening or burning.
