FUELS
WARNING: Use only kero-
sene, #1#2 diesel/fuel oil, JET
A or JP-8 fuels to avoid risk
of fire or explosion. Never use
gasoline, naphtha, paint thin-
ners, 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 mini-
mum fresh, outside air ventila-
tion requirements. If proper
fresh, outside air ventilation is
not provided, carbon monoxide
poisoning can occur. Provide
proper fresh, outside air ventila-
tion before running heater.
Fresh Air Opening Requirements
Heater Size Square Feet Opening
350,000 Btu/Hr
10.5
600,000 Btu/Hr
18.0
Note:
If you use more than one heater, provide extra
fresh air. Provide a fresh air opening of at least three
square feet for each 100,000 Btu/Hr rating.

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.

This thermostat is a general-heating control. It is not
intended for precise temperature control. Adjust ther-
mostat until heater cycles at the desired setting.
Note:
If starting heater for first time, you may need

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.
