• Heaters used in the vicinity of tarpaulins, canvas, or similar enclosure

materials shall be located a safe distance from such materials. The recom-

mended minimum safe distance is 10 feet. It is further recommended that

these enclosure materials be of a fire retardant nature. These enclosure

materials shall be securely fastened to prevent them from igniting or from

upsetting the heater due to wind action.

• Use only in well vented areas. Before using heater, provide at least a three-

square-foot opening of fresh, outside air for each 100,000 Btu/Hr of rating.

This heater produces carbon monoxide, which is listed by the State of Califor-

nia as a reproductive toxin under Proposition 65.

• Use only in places free of ﬂammable vapors or high dust content.

• Use only with the electrical voltage and frequency speciﬁed on model plate.

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.

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.

104042

THEORY OF

OPERATION

The Fuel System: The motor turns the fuel pump. The fuel pump pulls fuel from

the fuel tank. The fuel pump pushes fuel through a ﬁlter and a solenoid valve and out

the burner head nozzle. A ﬁne mist of fuel is sprayed into the combustion chamber.

The Air System: The motor turns the fan. The fan pushes air into and around the

combustion chamber. This air is heated and provides a stream of clean, hot air.

The Ignition System: The electronic ignitor sends voltage to the spark plug. The

spark plug ignites the fuel and air mixture.

The Flame-Out Control System: This system causes the heater to shut down if

the ﬂame goes out. It also allows the fan to continue running after normal shutdown

of heater. This cools the combustion chamber.

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 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

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 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 6.

2. Clean and ﬂush fuel ﬁlter and canister attached to fuel pump (see Fuel Filters

[Pump Fuel Filter], page 15).

3. Remove drain plug and drain fuel tank.

4. Replace drain plug.

5. If any debris is noted in old fuel, add 1 or 2 quarts of clean kerosene to tank, stir,

and drain again. This will prevent excess debris from clogging filters during

future use.

6. Replacefuelcapordrainplug.Properlydisposeofoldanddirtyfuel.Checkwith

local automotive service stations that recycle oil.

7. Add two gallons of clean kerosene or No. 1 fuel oil to fuel tank.
