Photograph 1 shows the front of the heating unit. All electrical and gas connections are made on the front side of the unit. How it works The heating system in your home comprises of three major components-the heater, the ducting and a wall-mounted thermostat. The heater will switch on when the room thermostat calls for heat. The heater draws air at room temperature through a return air duct. This air passes over a heat exchanger in the heater where it becomes warm. This warm air is then distributed throughout your home through the vents located in the floor.

NOTE: PLEASE READ THE OPERATING MANUAL CAREFULLY AND ACQUAINT YOURSELF WITH THE FEATURES OF THE APPLIANCE, OPERATING PROCEDURES AND WARRANTIES TO GAIN OPTIMUM PERFORMANCE FROM THIS HIGH EFFICIENCY UNIT. WARNINGS (1) Do not place articles on or against this appliance. (2) Do not use or store flammable materials near this appliance.

(3) Do not spray aerosols in the vicinity of this appliance while it is in operation. (4) Do not operate this appliance if you smell gas around it.

(5) Do not light the burners with a match or any other source of flame. (6) Do not operate this appliance with panels, covers or guards removed.

ELECTRONIC IGNITION

Your Rapid Response heater is equipped with an energy saving electronic ignition, which automatically lights the burner when the thermostat calls for heat. Do not manually light the burner with a match or any other source of flame. Note: If you have any concerns about your new system please contact your installer or our Service Division on: Tel. (03) 9800 2409. B): How to Operate Your Heater 1. OPERATING PROCEDURE

(a) Set the wall thermostat to the OFF position. (b) Open at least 6 or more vents. (c) Check that the gas supply is turned ON at the unit. (d) Switch ON the power supply. (e) Switch ON the thermostat and adjust the temperature setting to above the room

temperature.

The unit should start operating after 90 seconds. If the unit does not fire-up within 5 minutes (after 4 attempts) then go to step (f).

(f) Press the reset button on the thermostat and the unit should start operating within 60 seconds. If the thermostat does not have a reset button simply turn the thermostat off for 3 seconds and then back on again setting it above the room temperature.

Note: It is important that any trouble-shooting or repairs to this appliance be performed by a qualified technician only.

2. SEQUENCE OF OPERATION 1) When the thermostat is turned on it calls for heat. 2) The appliance enters a pre-purge period with the combustion fan running. 3) The igniter switches on. 4) The gas valve opens after the igniter is on. 5) The burner lights and the flame sensor detects the presence of the flame. 6) The igniter switches off. 7) The room fan turns on and blows warm air through the vents. 8) The heater will remain in operation until the thermostat reaches the preset

temperature and stops calling for heat, or for maximum one hour for routine safety check. The software of the PCB stops the heater after every hour for routine safety check and restarts it almost immediately.

9) Once the temperature is reached the gas valve will shut down and the room air fan will turn off after 20 secs.

10) If the flame sensor does not detect the flame the gas valve will shut down and the appliance will attempt another ignition cycle and will follow steps 2-7.

11) If the unit still fails to light press the reset button on the thermostat and the unit will go through its operating sequence again.

Note: If the system still fails to operate, contact our Service Division on (03) 9800 2409. 3. SHUTDOWN PROCEDURE If the heater is not going to be used for an extended period of time the following instructions should be followed:

(a) Turn the thermostat to the OFF position. (b) Turn the gas tap to the OFF position. This gas tap is located external to the unit and to

its close proximity. (c) Switch off power to the unit. There should be a switch close to the unit.

4. POWER FAILURE Should a power failure occur while the heater is in operation the burner and fan will switch off. No heating will be available until power is restored. On restoration of power the thermostat will automatically turn on the heater. Under some circumstances, on restoration of power the fan will run continuously without the burners being on. When this condition occurs it will be necessary to push the reset button on the over-temperature cut-out switch. This switch is located near the

combustion air inlet louvres.

5. THERMOSTAT OPERATION Once the heating system has been commissioned and balanced, it is simply a matter of controlling the unit from the thermostat as required.

6. MANUAL THERMOSTAT To turn on the heating system, set the dial on the thermostat to a comfortable temperature. A comfortable setting is between 18-21 degrees. The unit will cycle to maintain the preset temperature. To turn off the heating system, depress the HEAT button on the thermostat. Alternatively the dial can be turned down to a lower setting. Photograph 2 shows the location of dial and various buttons.

7. DELUXE PROGRAMMABLE THERMOSTAT (OPTIONAL) Refer to operating instructions provided with the thermostat. C): Return Air Filter If a return air filter is fitted to your heating system it should be removed for cleaning at regular intervals. During the heating season the filter should be cleaned at least twice a month. A blocked filter will restrict the airflow and possibly overheat the unit. This condition will result in poor performance of the heating system and might cause premature failure of the unit. This condition will void the given warranty. D): Outlets (Vents) It is important to keep a minimum of 6 outlets open for the RR20 and 10 outlets open for the RR25 at all times to prevent overheating and short-cycling the unit

E): Abnormal Operation Should any of the following characteristics occur, do not use the appliance and contact your local Stadt service agent or the gas utility immediately: • Smell of gas. • Unusual odours from outlets. • Smoke or fumes from outlets. • Excessive or unusual noises emanating from the appliance. F): Add-on Cooling Refrigerated Add On Cooling can be incorporated with heating unit at any stage provided the ductwork is suitably designed. Contact your Stadt dealer for further details.

G): Maintenance It is recommended that the unit be serviced every two years. This service is not covered by our warranty and a fee is applicable. Please contact our Service Division on (03) 9800 2409 to conduct preventative maintenance on your heating unit. The service technician will attend to matters such as: Checking gas pressure at unit Inspecting flues and flue passages Inspecting combustion and ventilation air passages and openings Cleaning of burners, injectors, combustion and room fan This maintenance helps to ensure that the unit is operating safely at peak performance.
