FUEL SPECIFICATIONS

KEROSENE (1-K)

For optimal performance of this heater, it is strongly suggested

that 1-K kero sene be used. 1-K kerosene has been refined to

virtually eliminate contami nants, such as sulfur, which can

cause a rotten egg odor during the operation of the heater.

However, #1 or #2 fuel oil (diesel fuel) may also be used if 1-K

kerosene is not available. Be advised that these fuels do not

burn as clean as 1-K kerosene, and care should be taken to

provide more fresh air ventilation to accommodate any added

contaminants that may be added to the heated space.

OPERATION

OVERVIEW OF HEATER DESIGN

Fuel System: This heater is equipped with a fuel pump (Gear) that

pulls fuel through the fuel line connected to the fuel tank and then

pushes fuel through a filter and a solenoid valve and out the burner

head nozzle.

This fuel is sprayed into the combustion chamber in a fine mist.

SureFire Ignition: The electronic ignitor sends voltage to a

specially designed spark plug. The spark plug ignites the fuel

and air mixture.

The Air System: The heavy duty motor turns a fan that forces

air into and around the combustion chamber. Here, the air is

heated and then forced out the front of the heater.

THE SAFETY SYSTEM

Temperature Limit Control: This heater is equipped with a

Temperature Limit Control designed to turn the heater off

should the internal temperature rise to an unsafe level. If this

device activates and turns your heater off, it may require

service.

Electrical System Protection: This heater’s electrical system is

protected by a circuit breaker mounted to the power switch that

protects PCB assembly and other electrical components from damage.

Flame-Out Sensor: Utilizes a photocell to monitor the flame in

burn chamber during normal operation. It will cause the heater

to shut off should the burner flame extinguish.

WARNING!

Fire and explosion hazard!

■ Kerosene should only be stored in a blue container that is

clearly mark ed “kerosene”. Never store kero sene in a red

container. Red is associ ated with gasoline.

■ NEVER store kerosene in the living space. Kerosene should

be stored in a well ventilated area outside the living area.

■ NEVER use fuel such as gasoline, benzene, alcohol, white

gas, camp stove fuel, paint thinners, or other oil

compounds in this heater (THESE ARE VOLATILE FUELS

THAT CAN CAUSE A FIRE OR EXPLOSION).

■ NEVER store kerosene in direct sunlight or near a source of

heat.

■ NEVER use kerosene that has been stored from one

season to the next. Kerosene deteriorates over time. OLD

KEROSENE WILL NOT BURN PROPERLY IN THIS HEATER.

■ Use 1-K kerosene in this heater. #1 fuel is a suitable

substitute.

FUELING YOUR HEATER

Never fill the heater fuel tank in the living space: fill the

tank outdoors.

Do not overfill your heater and be sure heater is level.

IMPORTANT: REGARDING FIRST IGNITION OF HEATER. The

first time you light the heater, it should be done

OUTDOORS. This allows the oils, etc., used in

manufacturing heater to be burned off outside.

TO START HEATER

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

2. Attach fuel cap.

3. Plug power cord into three prong, grounded extension

cord. Extension cord must be at least six feet long.

- Extension Cord Wire Size Requirements:

- 6 to 100 feet long, use 14 AWG conductor.

- 101 to 200 feet long, use 12 AWG conductor.

- 201 to 300 feet long, use 10 AWG conductor.

- 301 to 400 feet long, use 8 AWG conductor.

- 401 to 500 feet long, use 6 AWG conductor.

4. Turn “THERMOSTAT CONTROL KNOB” to desired setting (setting

range: 40°-110°F, 9 steps) and push power switch to “ON”

position. Power indicator lamp and room temperature display

will light and heater will start.

If heater does not start, the thermo -stat setting may be too low,

turn “THERMOSTAT CONTROL KNOB” to higher position to start

heater. If heater still does not start, turn power switch to “OFF”

and then to “ON” position (See Figure 10). If heater still does not

start, see Troubleshooting Chart on page 19.

NOTE: Room Temp. display indicates as following:

- When room temp. is less than 0°F: “Lo”.

- When room temp. is between 0°F and

99°F: Indicates room temperatures.

- When room temp. is more than 99°F: “HI”.

NOTE: The major electrical components of this heater are protected

by a circuit breaker mounted to the power switch. If your heater fails

to start, check this first and replace as necessary. You should also

check your power source to insure that proper voltage and

frequency are being supplied to the heater.

TO STOP HEATER

Heater must go through cooling cycle. The cooling cycle cools the

combustion chamber. Damage to heater can occur if combustion

chamber is not cooled. Do not restart heater until cooling cycle is

complete.

1. Turn “THERMOSTAT CONTROL KNOB” to lowest temperature

setting. This will cause heater flame to go out. The motor will

continue to run during the cooling cycle. This allows the fan to

cool the combustion chamber. When the cooling cycle (approx.

1 min.) is finished, the motor will stop. Do not turn switch to

“OFF” or unplug heater until cooling cycle is finished.

2. Turn switch to “OFF” and unplug power cord.

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

The cooling cycle cools the combustion chamber.

1. Wait until cooling cycle is finished after stopping heater.

2. Repeat steps under TO START HEATER.

WARNING!

Fire and explosion hazard.

■ Never refill fuel tank when heater is operating or

still hot.

LONG-TERM STORAGE OF YOUR HEATER

FUEL TANK DRAIN

1. Remove drain plug from rear bottom side of fuel tank by

pulling plug grip downward and drain. See Figure 12.

2. Using a small amount of kerosene, swirl and rinse the

inside of the tank.

NEVER MIX WATER WITH KEROSENE, as it will cause rust inside

the tank. Pour the kerosene out, making sure that you remove it

all.

IMPORTANT: Do not store kerosene over summer for use during

next heating season. Using old fuel may damage heater.

3. Reinstall drain plug as follows:

- Insert plug’s seal head fully into drain hole so that flange is

flush

to tank’s bottom. See Figure 13.

- Insert seal cap fully into head hole so that cap flange is

flush to head flange. See Figure 13.

IMPORTANT: Reinstall plug fully into hole in tank; otherwise it

will not seal completely.

- Make sure storage place is free of dust and corrosive fumes.

- Store the heater in the original box with the original packing

material and keep USER’S MANUAL with heater.
