TO STOP HEATER
CAUTION: Never unplug
heater while heater is running.
Heater must go through purge
cycle. The purge cycle cools the
combustion chamber. Damage
to heater can occur if combus-
tion chamber is not cooled. Do
not restart heater until purge
cycle is complete.
1. Turn thermostat dial to lowest temperature
setting. This will cause heater flame to go
out. The motor will continue to run during the
purge cycle. This allows the fan to cool the
combustion chamber. When the purge cycle
is finished, the motor will stop. Do not unplug
heater until purge cycle is finished.
2. Unplug extension cord from outlet.
3. To temporarily
stop heater, set thermostat at
a temperature lower than air around heater.
Heater will cycle back on if air temperature
around heater matches thermostat setting.
TO RESTART HEATER
CAUTION: Do not restart
heater until purge cycle is fin-
ished. The purge cycle cools the
