SAFETY

INFORMATION WARNINGS

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.

Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning

resembletheﬂu,with headaches, dizziness, or nausea. If youhavethesesigns,the

heater may not be working properly. Getfresh air atonce!Have heater serviced.

Some people are more affected by carbon monoxide than others. These include

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

influence of alcohol, and those at high altitudes.

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 to avoid risk of ﬁre or explosion. Never

use gasoline, naphtha, paint thinners, alcohol, or other highly ﬂammable

fuels.

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

vapors are present.

• Follow all local ordinances and codes when using heater.

• Use only in well-vented areas. Provide at least a 2800 square cm (3-square-

foot) opening of fresh, outside air for each 29.3 kW (100,000 BTU/Hr) of

rating.

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

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

• Use only a three-prong, grounded (earthed) extension cord.

• Minimum heater clearances from combustibles:

Outlet: 250 cm (8 Ft.) Sides, Top, and Rear: 125 cm (4 Ft.)

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

occur.

• When moving or storing heater, keep heater in a level position or fuel

spillage may occur.

• Keep children and animals away from heater.

• Unplug heater when not in use.

• When used with thermostat, heater may start anytime.

• Never use heater in living or sleeping areas.

• Never block air inlet (rear) or air outlet (front) of heater.

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

• Never attach duct work to front or rear of heater. Using duct work could

reduce the necessary air flow of heater. Heater would produce excessive

carbon monoxide.

DANGER

Carbon monoxide poisoning may lead to death!

THEORY OF

OPERATION The Fuel System: The air pump forces air through the air line. The air is then

pushed through the burner head nozzle. This air causes fuel to lift from the tank. 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.

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

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

IMPORTANT:

Use a KEROSENE ONLY container. Be sure storage container is

clean. Foreign matter such as rust, dirt, or water will cause the 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.

VENTILATION

Continued

Provide a fresh air opening of at least 2800 square cm (3 square feet) for each 29.3

kW (100,000 BTU/Hr) rating. Provide extra fresh air if more heaters are being

used.

Example:

A 44 kW (150,000 BTU/Hr) heater requires one of the following:

• a 4.88 m (16 foot) wide two-car garage door raised 8.59 cm (3.38 inches)

• a 2.75 m (9 foot) wide single-car garage door raised 15.24 cm (6 inches)

• two, 76.20 cm (30 inch) wide windows raised 28 cm (11 inches)

WARNING

Follow the minimum fresh, outside air ventilation

requirements. If proper fresh, outside air ventilation is not

provided, carbon monoxide poisoning can occur. Provide

proper fresh, outside air ventilation before running heater.

OPERATION WARNING

Review and understand the warnings in the

Safety

Information Section.

They are needed to safely operate this

heater. Follow all local codes when using this heater.

To Start Heater

1. Follow all ventilation and safety information.

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

3. Attach fuel cap.

4. Plug power cord of heater into standard 230 volt/50 hertz, grounded (earthed)

outlet. Use an extension cord if needed. Use only a three-prong, grounded

(earthed) extension cord.

Extension Cord Wire Size Requirements

Up to 30.5 meters (100 feet) long, use 1.0 mm2(16 AWG) conductor

30.6 to 61 meters (101 to 200 feet) long, use 1.5 mm2(14 AWG) conductor

Heater will start when power cord is plugged into outlet. If not, push in flame-

out control reset button (see Figure 4).
