chamber. Damage to heater can occur if combustion chamber is
not cooled. Do not restart heater until purge cycle is complete.

1. Drain all fuel from fuel filters, fuel lines, and pump (see Fuel Filters [Tank Fuel
Filter], page 17).
2. Clean and flush fuel filter and canister attached to fuel pump (see Fuel Filters
[Pump Fuel Filter], page 17).
3. Remove drain plug and drain fuel tank.
4. Replace drain plug.
5. Add one gallon (four liters) of clean kerosene to fuel tank.

To Restart Heater
CAUTION
Do not restart heater until purge cycle is finished. The purge
cycle cools the combustion chamber.
1. Wait until purge cycle is finished after stopping heater.
2. Repeat steps under To Start Heater, page 8.
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.
