13.4.4 PROCEDURE FOR INITIAL LIGHTING

IF THE UNIT IS TO OPERATE ON LPG REFER TO SECTION 13: LPG FUEL BEFORE PROCEEDING
1. Ensure that the gas-inlet appliance isolating valve, provided by the installer, is in the "off" position.
2. Press the power rocker switch, positioned on the front of the appliance next to the control thermostat, to
bring the equipment on. See Figure 12.1 or 12.2 for location.
3. Set the control thermostat to a value above that of the stored water.
4. The combustion fan should start and purge the combustion chamber. The spark generator should
create a spark and the gas solenoid should open. As the gas-inlet appliance isolating valve is closed the
appliance should go to a flame failure condition within 10 seconds this will be indicated by a red lock-out
light on the control panel.
5. If the above occurs correctly, open the gas-inlet appliance isolating valve and reset the unit by
depressing the red lock-out light on the control panel and a new ignition cycle will begin.
6. The combustion fan will repeat the pre-purge procedure and attempt to light. Once a flame is
established, the green 'Burner On' lamp, located on the control panel, will illuminate.
7. Allow the system to reach temperature to check operation of control thermostat.
8. Once the thermostat has been satisfied, check that the flame has been extinguished.
