– Temperature switches
CAUTION
Once full contact is made with the tank surface it can take up to 15 minutes
for the switch to automatically reset. Once the switch has closed, the
control circuit will allow gas to flow to the main heater.
The lower switch will activate when the tank is empty and will shut off gas
flow to both the pilot and main heater. This will require a cold restart
procedure once the tank has been refilled. Activating (opening) the upper
temperature switch will shut-off gas flow to only the main heater and will
allow the pilot heater to continue to operate. Once the tank has been filled,
the main heater will come on automatically.
Heater should be turned OFF while refueling the tank.

Ensure that both switches
are in full contact with the
