It is a Climate Technologies recommendation that all Gas Ducted Central Heaters are wired with a dedicated circuit from the distribution board with a separate circuit breaker. It is the requirement of AS3000 (Wiring Rules) that if a ducted central heater is fitted with a Dual Cycle Refrigerative Air conditioner, the heater must be fitted with a dedicated circuit and circuit breaker.

ELECTRICAL 1. Have a licensed Electrician install a 10 Amp 3 pin GPO (general-purpose outlet)

within 600mm of the heater, electrical entry.

Note: Ensure the polarity of the outlet is correct otherwise

the flame cant be sustained and the heater wont operate.

2. Plug the pre-wired service lead into the GPO. Note: Do not use an extension cord to reach the GPO. This

is illegal and unsafe. An Electrician must relocate the GPO

3. Follow the wiring diagram printed on the appliance to connect to thermostat cables to the control board.

4. The room air fan high speed is factory set to the maximum speed.



Gas Connections

Gas Connections

GAS - IMPORTANT NOTE When connecting the gas supply inlet pipe to the gas valve, hold the connection nipple on the valve with a spanner while tightening the inlet pipe compression nut. This ensures the nipple is not over tightened. Cracked gas valves or regulator castings due to over tightening during installation or service are not the manufacturer s responsibility.

Gas Connections 1. A gas cock is not supplied. The installer must supply an AGA approved gas cock

to suit the gas specified. Natural Gas: The connection on heater is a BSP compression fitting onto which the inlet pipe and gas cock is to be fitted. LP Gas: The connection on the heater is a BSP compression fitting onto which the Inlet pipe and gas cock is to be fitted. A Liquefied Petroleum gas regulator, approved to AG205, must be fitted according to the installation code AS5601 (AG601) when using a LPG burning heater. It must be capable of providing the heater with 1.4 m3/h minimum flow rate at 2.75kPa pressure with all other gas appliances operating at full demand.

2. The gas cock must be fitted outside the heater casing where it can be easily and quickly turned on or off.

3. Use gas copper pipe to AS 1432 Type B 4. Do not saddle gas pipe to heater. 5. Refer to the specification label on the appliance for burner pressure information.



Combustion Requirements

Combustion Air Requirements

VENTILATION AIR INLETS Refer AS5601 (AG60I) Sec 5.4 and associated clauses Locate the ventilation air inlet as far as possible from a swimming pool or swimming pool pump house. Chlorine fumes when burning in the heater will attack the heat exchanger. If the heater is installed in a ventilated enclosure (e.g. in the roof or under the floor) the space must meet the minimum volumes shown below.

Model - minimum enclosure (m3)

Minimum Enclosure (m3) Model 15kW - 60MJ 20

21kW - 85MJ 30

30kW - 120MJ 40

35kW - 140MJ 50

If the volume is less than required then one of the following methods of ventilation must be used.

Ventilation direct from outside (A = 3 x MJ/hr) Two permanent ventilation openings must be provided directly to outside. The minimum free ventilation area A required for each model is shown in the table below and is the sum of all holes, slots and other apertures.

Model - free ventilation area (cm2)

Model Minimum Ventilation Area (cm2)

15kW - 60MJ 180

21kW - 85MJ 270

30kW - 120MJ 360

Any holes, slots or other apertures in the ventilation openings must be 6mm or more. Dimension a plus dimension b must not be greater that 5% of the total height h of the enclosure (see diagram on opposite page).

35kW - 140MJ 450



Combustion Requirements

Ventilation via an adjacent room (A = 6 x MJ/hr) Two permanent ventilation openings must be provided in the enclosure. The minimum free ventilation area A required for each model shown in the table below

Model Minimum Ventilation Area (cm2)

15kW - 60MJ 360

21kW - 85MJ

540

30kW - 120MJ 720

35kW - 140MJ

900

Any holes, slots or other apertures in the ventilation openings must be 6mm or more. Dimension a plus dimension b must not be greater that 5% of the total height h of the enclosure (see diagram). These requirements must apply to all adjacent enclosures until an enclosure is ventilated outside or until the enclosure is larger than the minimum size required for the unit rating.

Ventilation air inlet requirements for units installed in spaces smaller than the rated minimum enclosure figure.



Exhaust Flue Location

Exhaust Flue Location Positioning the flue terminal

Refer AS5601 (AG60I) Section 5.13.6.5 Fig 5.3 The flue terminal must be positioned using the following guidelines.

IT IS IMPORTANT THAT FLUE GASSES DO NOT ENTER THE BUILDING OR PRESENT A THREAT TO LIFE.

35kW 140MJ 14" (355mm)

PLEASE NOTE: The spigot sizes provided above are unit connection details only. The duct sizes required for the discharge and return air should be selected as per the product sizing guide recommendations to achieve best air flows.

GENERAL The heater will operate at its optimum with a correctly designed, efficient ducting system. Avoid over-sizing the heater. The best and most economical central heating is obtained by selecting the correct sized unit for the job. Over sizing can shorten the life of the heater, create stratification and increase noise levels and running costs. The following points all have some effect on the total system efficiency.

Ensure that a door, movable partition, furniture, curtain or other items cannot block the return air grille.

The return air grille must be sized to accept the full air capacity of the system at low noise level. Refer to product sizing guide.

Do not place the return air grille in a location where the returning air is drawn over people.

Warm air flowing from the outlets in each room must be able to return freely back to the return air grille. This is achieved by cutting 25mm from the bottom of each door or by fitting door relief grilles.

Where possible, the return air grille should be installed close to floor level for best system performance.

If a filter is to be fitted in the return air duct, it should be easily accessible for cleaning.



Ducting

DUCTING & DUCT FITTINGS Do not place an outlet register near the controller/thermostat as this can cause

false readings

Do not place registers so that air is blown over people e.g. under tables, or a skirting register mounted horizontally under a sink or wash basin

To avoid exceeding maximum allowable air pressure drop in ducted system, do not use excessive lengths of duct. If a duct run exceeds 6 metres always install the next size larger ductwork. Note: Duct register in small rooms with partially closed baffles to limit

airflow must be considered as half a register. Flexible ductwork must be run as straight as possible between the heater outlet

and warm air outlets. Make sure there is at least 1500mm of straight ducting at the heater outlet.

The airflow through each outlet must be individually set to air balance the system.

The maximum discharge air temperature should not exceed 60-65C at 300mm from the unit discharge with the room at normal operating temperature.

Use a minimum of one outlet in every average sized room. A second outlet will be required for unusually large rooms or a bedroom with ensuite.

Refer to product sizing guide for the ductwork sizing guide. All ductwork should be streamlined avoiding sharp angles that will reduce airflow. Ensure all ductwork is taped airtight so that there is no leakage. Balancing dampers maybe required to ensure even air distribution. Always install damper blades in the branch take off fittings. Ensure that the final ductwork bend to

each ceiling register is a smooth radius so that the airflow is even from the register into the room. The minimum radius bend is 1.5 times the duct diameter.

Do not squash ductwork to fit through opening, as airflow will be restricted. Find a better location.

If more than 6m of flexible ductwork is required in one length, the next available size flexible duct must be used.

Commissioning

BURNER PRESSURE SETTING Dynamic Pressure

To check dynamic gas pressure:- 1. Remove the test point screw. 2. Fit the manometer tube and check the reading against the stated supply

pressure on the customers supply regulator. 3. If the correct supply pressure is not available, contact the local gas authority to

obtain the correct pressure. 4. Remove the manometer tube, replace test point screw and check for leaks.

Commissioning

Burner Pressure Setting the burner pressure is done in 2 parts. The high pressure must always be set before the low pressure can be correctly established.

High Burner Pressure To set the high burner pressure correctly, the combustion fan must be set to run on maximum RPM so that modulation can not take effect. 1. Remove the pressure test point screw. 2. Place the manometer tube on the gas inlet

pressure test point 3. To set the combustion fan to high speed shift the

wire on CFAN on the Series3 modulating control board to a spare neutral terminal

4. To adjust the burner pressure, remove the plastic cover from the adjustment screw on top of the gas valve diaphragm. A small blade screw driver is required to adjust the pressure. Do not make large adjustments

5. Set the burner pressure as per the specifications laid out on the unit rating label

6. Return the combustion fan wire back to CFAN 7. Leave the manometer in place to check low

pressure.



Commissioning

Setting the Low Burner Pressure Setting the low burner pressure must only be set after the high burner pressure has been verified. The low burner pressure is set by adjusting the low speed modulation of the combustion fan. To set the low burner pressure: 1. Ensure the combustion fan wire has

been returned from neutral to CFAN. 2. Unplug the thermistor wire from the

modulating control board. 3. Using a Phillips head screwdriver,

adjust the low gas rate pot on the modulating control board. This will require movements in very small increments

4. Adjust the low burner pressure as set out on the gas rating label.

5. Replace the thermistor wire to the modulating control board

6. Remove the manometer, replace pressure test point screw and check for leaks.

CHECKING THE SYSTEM PERFORMANCE Once the gas pressure has been set, check the air discharge temperature in the duct to confirm the correct operation of the central heater. To test the correct operation of the heater: 1. Set room air fan speed best suited to the system. Replace electrical cover. 2. Check the temperature rise through the heater. The air temperature 300mm from

the heater discharge should be between 60 to 650C at normal room temperature. Failure to comply will result in unsatisfactory performance of the heater. If this temperature is exceeded, check the ducting system for airflow restrictions and correct if necessary. If the temperature is still too high, increase the high fan speed setting.

3. Using the thermostat, switch the heater OFF. Wait for the room air fan to cease operation (approximately 80 seconds), then switch ON again to recheck the starting sequence.

4. Using the thermostat, switch the heater OFF unless the customer requires that it be left running.

5. Before leaving, make sure that the customer understands how to operate the heating system.
