Heater Operation
Shut Down Process
The heater should only be controlled using the operating switches provided. Switching the heater
off by interrupting it’s power source will bypass the heater’s normal cool down process and will cause
stress and premature wear of the combustion components.
Switching Off – Heater can be switched off either manually, via timer control or through it’s own
temperature regulation. Refer to Operating Switch Instructions for details.
Purge Cycle – Once switched off, the heater will switch into high operating mode for a short duration to clear
it’s combustion chamber (Approximately 100 seconds).
Cool Down Cycle – Upon completion of the Purge Cycle, the fuel pump will switch off, blower will slow
down and the flame will quickly extinguish. The blower will switch to high speed and continue to operate
to further purge the combustion chamber and cool down the heat exchanger. The cool down cycle will last
approximately 4 minutes.
Safety Systems
The heater is equipped with several control features to protect itself and the operator.
Systems Check:
The heater will not attempt to start if one of the components is detected by the control unit to be
defective. If the heater detects a problem during operation it will shut down and depending on the fault
it will either restart automatically or it will turn off completely.
No Start Safety Time:
If the heater does not ignite on the first start attempt, it will shut off the fuel pump and the start
sequence will repeat. After two unsuccessful starting attempts the controller will turn the heater off in
order to prevent fuel flooding the burner chamber. You can restart the process by switching the heater
OFF and then ON again.
Flame Out:
If the flame goes out during operation, the heater will shut down and then attempt to restart
automatically. If the heater does not ignite, it will shut down. It will need to be turned OFF and ON
manually.
