OPERATION

FUELS
WARNING: Use only kerosene or No. 1 fuel oil to
avoid risk of fire or explosion. Never use gasoline,
naphtha, paint thinners, alcohol, or other highly
flammable fuels.
Do not use heavy fuels such as No. 2 fuel oil or No. 2 diesel. Using
heavy fuels will result in:
• clogged fuel filter and nozzle
• carbon build-up on spark plug
• the need of non-toxic anti-icer in fuel during very cold weather
IMPORTANT: Use a KEROSENE ONLY storage container. Be
sure storage container is clean. Foreign matter such as rust, dirt, or
water will cause flame-out control to shut down heater. Foreign
matter may also require you to clean fuel system often.
VENTILATION
WARNING: Follow the minimum fresh, outside air
ventilation requirements. If proper fresh, outside air
ventilation is not provided, carbon monoxide poison-
ing can occur. Provide proper fresh, outside air ven-
tilation before running heater.

6. Plug power cord of heater into three-prong, grounded exten-
sion 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 out-
let. 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 thermo-
stat 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 bleeder 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.
