A wide choice of accessories has been designed to ensure the highest flexibility of installation.

The solution described below uses the connection kit (code 26110LP) and hydraulic compensator (code 26125LP)

for the control of different flow rates between the primary and possible secondary circuits.

HYDRAULIC VERTICAL CONNECTION KIT cod. 26110LP

For a direct connection to the boiler. On the return connection a strainer has been included to protect the boiler from any dirty or impurity that may cause obstructions.

The Kit includes: 1. strainer 2. isolating valve 3. expansion vessel connection 4. water pressure gauge connection socket 5. filling loop connection (5. INTERN: Heating system

filling point) HYDRAULIC COMPENSATOR KIT cod. 26125LP

The use of a compensator is recommended when there is a primary circuit with its own circulating pump and a secondary circuit with one or more circulating pumps. The compensator will negate situations whereby the different pumps of the circuit will interact one with another creating abnormal flow variations.

The compensator will create a low pressure loss zone so that the primary circuit (of the boiler) will become independent from the secondary circuit to guarantee flexibility of installation and on systems with several pumps, high flow rates and high pump heads

The Kit includes: 1. washer (x2) Ø1”1/2; 2. washers (x2) Ø2”1/2; 3. hydraulic compensator ; 4. Ø2”1/2 => Ø2” adapters;

3-WAY VALVE KIT cod. 26097LP

It is possible to connect the boiler to a storage cylinder for the domestic hot water production by installing the 3-Way valve Kit. The installation of the 3-way valve kit (on the heating return) requires the use of a chronostat for the boiler control, excluding the use of a cascade regulator. The kit includes a 3- Way valve, a cylinder DHW temperature sensor (8 metres length) that will be connected to the boiler main pcb to enable the correct setting and data display (DHW temperature)

The Kit includes: 1. htg flow manifold to DHW storage cylinder Ø1”1/2; 2. htg return manifold from DHW storage cylinder Ø1”1/2; 3. 3-way valve; 4. storage cylinder dhw temperature sensor;

HYDRAULIC MANIFOLD KITS FOR CASCADE INSTALLATION For the installation of 2 or more boilers in cascade up to a maximum of 4 boilers.

Available kits:

− cod. 26164LP

Hydraulic manifold kit for 2 boilers in cascade installation

− cod. 26163LP Hydraulic manifold kit for 1 additional boiler in cascade installation

Hydraulic manifold kits are complete with:

− isolating valves: to guarantee ease of maintenance/service or a temporary exclusion of only 1 boiler without interrupting the cascade installation operation;

− non-return valve: for each individual boiler to avoid any circulation while the boiler is OFF;

− strainer: to protect the boiler from eventual obstruction created by impurities of the hydraulic circuit;

Every hydraulic manifold Kit includes: Strainer Isolating valves Heating flow vertical connector Ø1”1/2 Heating return vertical connector Ø1”1/2 Heating flow manifold DN 65 PN6 Heating return manifold DN 65 PN6 Non-return valve Ø1”1/2

HYDRAULIC COMPENSATOR KIT – DN150 cod. 26116LP The use of a compensator is recommended when, in the same hydraulic system, there is a primary circuit (with its own pump) and a secondary circuit with one or more circulating pumps. The compensator will negate situations whereby the different pumps of the circuit will interact one with another creating abnormal flow variations. The compensator will create a low pressure loss zone so that the primary circuit (of the boiler) will become independent from the secondary circuit to guarantee flexibility of installation and on systems with several pumps, high flow rates and high pump heads. In this case the individual circuit head is controlled and determined by the performance/head of individual pumps.

The Kit includes: 1. Hydraulic compensator (DN150) with DN 65 PN 6

connections; 2. Washer for flange PN 6; 3. Automatic air vent; 4. heating flow temperature sensor socket 5. filling loop connection (gb) – 5- heating system filling point (int); 6. drain tap;

The RK 50 boiler is approved for both an indoor installation (boiler room or other) with or without modular box units or outdoor installation in modular box units.

The manufacturer recommends the use of Radiant original parts and accessories.

Individual boiler installation: a wide choice of flue kit option for the exhaust of combustion products into a flue duct or directly outside according to local regulations.

Flue kits and parts are in polypropylene material (for coaxial type flue kits, the inner pipe is in polypropylene, the outer pipe is in aluminium) to guarantee the highest mechanical resistance to the chemical action of the condensate and an easy installation.

FLUE MANIFOLDS

With cascade installation systems it is possible to discharge combustion emissions in only one flue duct using MK 50 flue manifold kit.

Available kits: :

kit MK50 – Flue manifold kit Ø125 in PP for 2 boilers in cascade installation – cod. 82103LP; kit SK50 – Flue manifold kit Ø125 in PP for 1 additional boiler in cascade installation – cod. 82104LP;

Flue manifold are in polypropylene material to guarantee the highest mechanical resistance to the chemical action of the condensate and an easy installation.

Each individual boiler can be connected to the main manifold through the appropriate connector equipped with a mechanical non-return damper to avoid a flow back of combustion products when one or more boilers are not in operation.

The system is completely realised in polypropylene material (PP) and thanks to the simple male/female installation system it guarantees easy and secure installation. Centring elements supplied with the system guarantee the perfect centring and vertical run of the rigid pipe. In the presence of flue ducts/chimneys with a not perfect straight-line run it is recommended the use of a flexible pipe system.

CASCADE REGULATION SYSTEM The purpose of the installation of a modular condensing boiler is to have a system that supplies the precise heat

demand from the plant under any variability condition, while at the same able to satisfy and manage any type of

user. For this reason, the management of the RK 50 boiler, either standalone or in cascade formation is possible

through the use of a series of accessories aimed at optimising the climatic control of the heat generating plant while

making full use of the boiler output. SYSTEM CHARACTERISTICS:

Sequence control for up to a maximum of eight boilers. Used to manage, control and programme the operating sequence of the boilers connected to the cascade

installation. The sequence control can be preset and programmed by means of parameters that allow ideal

temperature conditions to be guaranteed at all times during the day and night, seven days a week, for both the

domestic hot water and central heating systems. In addition to being panel-mounted, the regulator can also be wall-mounted separately in its own housing.

management, regulation and control of the secondary central heating and domestic hot water circuits. The regulator manages:

- central heating: a direct circuit and a mixed circuit with control of the mixer valve and dedicated pumps. The

use of additional regulators allows the system to manage up to 15 mixed secondary circuits. - domestic hot water: a circuit feeding the domestic hot water production system with the option to add one or

more dedicated exclusive service boilers in the sequence. When there is a demand for domestic hot water, the

regulator will only activate the enabled boilers. operation programming and dedicated working curve regulation for each individual secondary circuit.

The installation of an outside sensor makes it possible to automatically reduce or increase the maximum flow

temperature of the system in line with the increase or decrease in the outside temperature in order to balance

the power supplied to the system. room temperature control through the installation of a zone regulator. The zone regulator only functions when coupled to the cascade regulator and allows easy programming and

display of the domestic hot water circuit parameters (timer programme, actual nominal temperature of the hot

water) and central heating circuit parameters (timer programme and required room temperature) for the central

heating plant in the user’s living area. It is thus possible to have continuous control over the central heating

system and as such optimise it. “CAN Bus” line for connecting the zone regulator and the additional modules to the cascade regulator enabling

management of up to 8 heater modules and 15 mixed circuits

remote system management with the option to programme and display all the specific parameters of the plant

remotely.
