OPERATION

WARNING: Review and understand the warnings in the Safety Information section, page 2. They are needed to safely operate this heater.

TO START HEATER

1.Follow all ventilation and safety information.

2.Locate heater to provide maximum circulation of the heated air. Follow all location require- ments noted in Safety Information, page 2.

3.Fill fuel tank with kerosene or #1 fuel oil.

4.Attach fuel cap.

5.Set thermostat dial to desired temperature. Note: Thermostat setting must be higher than surrounding air temperature.

6.Plug power cord of heater into three-prong, grounded extension cord. Extension cord must be at least six feet long.

WARNING: Use only a three- prong, grounded extension cord. Use cord with proper wire size to assure 120 volt operation. See Extension Cord Wire Size Requirements below.

Extension Cord Wire Size Requirements

6 to 100 feet long, use 14 AWG rated cord 101 to 200 feet long, use 12 AWG rated cord 201 to 300 feet long, use 10 AWG rated cord 301 to 400 feet long, use 8 AWG rated cord 401 to 500 feet long, use 6 AWG rated cord

7.Plug extension cord into standard 120 volt/60 hertz, three-hole, grounded outlet.

8.The motor will start when extension cord is plugged into outlet. The heater should ignite at once. If heater does not ignite, restart heater. To restart heater, wait 60 seconds, then push in flame-out control reset button. Flame-out control reset button is at rear of heater near power cord (see Figure 4).

Note: A cold heater may affect the thermostat setting. This thermostat is a general-heating control. It is not intended for precise temperature control. Adjust thermostat until heater cycles at the desired setting.

Note: If starting heater for first time, you may need to prime the pump. If equipped, slightly open bleed-

er valve of pump to allow air to escape. Quickly close valve once fuel is seen. Wipe up any excess fuel. If equipped with canister fuel filter, remove the canister bottom and fill with fuel. Reassemble filter. Wipe up any excess fuel. You may also have to do this after taking heater out of storage.

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 combustion chamber.

1.Wait until purge cycle is finished after stopping heater.

2.Repeat steps under To Start Heater.
