TO STOP HEATER
CAUTION: Never unplug heat-
er while heater is running. Heater
must go through purge cycle. The
purge cycle cools the combustion
chamber. Damage to heater can
occur if combustion 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 ame 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 nished, the motor will stop. Do not
unplug heater until purge cycle is nished.
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 n-
ished. The purge cycle cools the
combustion chamber.
1. Wait until purge cycle is nished after
stopping heater.
2. Repeat steps under To Start Heater.
Note: If starting heater for rst time, you may need
to prime the pump. If equipped, slightly open bleed-
er valve of pump to allow air to escape. Quickly
