  If your Coonara Heater fails to ignite or ignites and then goes out, several factors could be at play. First, ensure that the gas supply is connected, fully purged, and at the appropriate pressure. Next, verify that the unit is properly plugged in and the switch is turned on, and check the supply fuse. Also, ensure there's sufficient time (at least 15 seconds) between ignition attempts to allow the combustion chamber to purge. It's also worth checking that all internal wiring plugs are correctly connected and located. The gas valve pressures may need adjustment. Finally, ensure the combustion fan and air pressure switch are working, and that the active, neutral, and earth wires are correctly oriented and connected.

  If the room fan in your Coonara Heater isn't operating, remember that it has a delayed start and won't activate until the unit warms up. Check the wiring to ensure it's properly connected. Make sure the fan is installed in the correct location and that nothing is blocking it. If blocked, remove and clean the fan.

  If your Coonara Heater unit cuts out after running for a while and then cycles on and off, this could be due to a heat exchanger blockage, which requires cleaning. Ensure the correct gas type is being used, with the appropriate injector size and pressure setting. Also, consult the section addressing issues with the room fan, as this could be related.
