SAFETY

INFORMATION

IMPORTANT: Read this Owner’s Manual carefully and completely

before trying to assemble, operate, or service this heater. Improper

use of this heater can cause serious injury or death from burns, ﬁre,

explosion, electrical shock, and carbon monoxide poisoning.

Early signs of carbon monoxide poisoning resemble the ﬂu, with headaches,

dizziness, and/or nausea. If you have these signs, the heater may not be working

properly. Get fresh air at once! Have heater serviced. Some people (such as

pregnant women, persons with heart or lung disease, persons with anemia, those

under the inﬂuence of alcohol, and those at high altitudes) are more affected by

carbon monoxide than others.

Make certain you read and understand all Warnings. Keep this manual for

reference. It is your guide to safe and proper operation of this heater.

• Use only kerosene or No. 1 fuel oil.

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

• Heater must be grounded. Use only a properly grounded three-wire extension

cord. Plug into grounded outlet only.

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

• Minimum clearance from any combustible materials: 8 feet (244 cm) from hot

air outlet; 6 feet (183 cm) from top; and 2 feet (61 cm) from sides and inlet.

• Locate heater on a stable and level surface while hot or operating or a fire may

occur.

• Use only in well ventilated areas. Provide ventilation of at least three square feet

(2,800 square cm) for each 100,000 Btu of rating.

• Keep children and animals away from heater at all times.

• Never start heater when combustion chamber is hot or if fuel has

accumulated in combustion chamber.

• When used with a thermostat, heater may start at anytime.

• When heater is moved or stored, it must be in a level position or fuel spillage may

occur.

• Use heater only in accordance with local ordinances and codes.

• Never use gasoline, crankcase drainings, naphtha, paint thinners, alcohol, or

other highly flammable fuels.

• Never use heater where gasoline, paint thinner, or other highly flammable vapors

are present.

• Never use heater in living or sleeping areas.

• Never leave a heater plugged in without adult supervision if children or animals

are likely to be present.

• Never move, handle, refuel, or service a hot, operating, or plugged-in heater.

• Never block air inlet at motor end (rear) of heater.

• Never attach duct work to front of heater.

• Never attach heater to external fuel tank.

The Fuel System: An air pump is located on one end of the motor shaft. The

air pump forces air through the air line. The air is then pushed through the burner

head nozzle. The moving air causes fuel to be lifted from the tank. The fuel and air

mixture is sprayed into the combustion chamber in a fine mist.

The Air System: The motor turns a fan which 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 causes the spark plug to ignite the

fuel and air mixture.

The Safety Control System: This system causes the heater to shut down if the

flame goes out.

099618

Use only kerosene or No. 1 fuel oil. Do not use heavy fuels such as No. 2 fuel oil

or No. 2 diesel. The use of heavy fuels will result in:

• clogging of fuel filter and nozzle

• carbon build up on spark plug

• the need of non-toxic anti-icer in fuel during very cold weather

Do not use No. 3 fuel oil or heavy oils such as crankcase drainings. These heavy

oils will not ignite properly and will contaminate the heater.

IMPORTANT:

Use a KEROSENE ONLY storage container. Be sure storage

container is clean. Foreign matter such as rust, dirt or water will cause the heater’s

safety control to shut down heater. Foreign matter may also require heater’s fuel

system to be frequently cleaned.

To Start Heater

1. Fill fuel tank with kerosene or No. 1 fuel oil.

2. Attach fuel cap.

3. Follow all ventilation and safety information.

Example:

A 150 model heater requires one of the following:

• a two-car garage door raised six inches (15.24 cm)

• a single-car garage door raised nine inches (22.86 cm)

• two, thirty-inch (76.20 cm) windows raised twelve inches (30.48 cm)

FUELS

WARNING

Use only kerosene or No. 1 fuel oil to avoid risk of fire or

explosion. Never use gasoline, crankcase drainings, naph-

tha, paint thinners, alcohol, or other highly flammable fuels.

WARNING

Provide a fresh air opening of at least one square foot (930

square cm) for each 35,000 BTU/HR rating. Provide extra

fresh air if more heaters are being used. The minimum

ventilation requirements must be followed to avoid risks

associated with carbon monoxide poisoning. Make certain

these requirements are met prior to operating heater.

VENTILATION

OPERATION

IMPORTANT

Review and understand the warnings in the Safety Information Section.

They are needed to safely operate this heater. Follow all local ordinances

and codes when using this heater.

4. Plug heater’s power cord into approved, grounded, three-wire extension cord.

Extension cord must be at least six feet (1.8 meters) long.

Extension Cord Size Requirement

6 to 10 feet (1.8 to 3 meters) long, use 18 AWG (0.75 mm

2

) rated cord

11 to 100 feet (3.3 to 30.5 meters) long, use 16 AWG (1.0 mm

2

) rated cord

101 to 200 feet (30.8 to 61 meters) long, use 14 AWG (1.5 mm

2

) rated cord

5. Plug extension cord into standard 120 volt/60 hertz, 3-prong grounded outlet.

Heater will start when extension cord is plugged into outlet. If not, push in

heater’s safety control reset button (see Figures 6 and 7).

Note:

If shipping, transport companies require fuel tanks to be empty.

1. Drain fuel tank.

Note:

Some models have drain plug on underside of fuel tank. If so, remove

drain plug to drain all fuel. If heater does not have drain plug, drain fuel

through fuel cap opening. Be sure all fuel is removed.

2. Replace drain plug if provided.

3. 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.

4. Replace fuel cap or drain plug. Properly dispose of old and dirty fuel. Check

with local automotive service stations that recycle oil.

5. If storing, store heater in dry place. Make sure storage place is free of dust and

corrosive fumes.

IMPORTANT:

Do not store kerosene over summer months for use during next

heating season. Using old fuel could damage heater.

WARNING

To avoid risk of burn and electrical shock, never attempt to

service heater while it is plugged in, operating, or hot.
