WARNINGS:

1. RISK OF INDOOR AIR POLLUTION!

•Use this heater only in well ventilated areas. Provide at least a three-square foot (2800 sq. cm.)

opening of fresh outside air for each 100,000 BTU/hr. of heater rating.

•People with breathing problems should consult a physician before using the heater.

•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 the 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, or those at high altitudes.

• Never use this heater in living or sleeping areas.

2. RISK OF BURNS/FIRE/EXPLOSION!

4. KEROSENE (1-K)

It is EXTREMELY IMPORTANT for the proper operation of this heater that you use the correct grade

of kerosene. The correct grade of kerosene is identified as 1-K kerosene.

1-K Kerosene has been refined to virtually eliminate contaminants such as sulphur, which can cause

a rotten egg odor during operation of the heater. #1 fuel oil may be used if 1-K kerosene is not available.

KEROSENE SHOULD ONLY BE STORED IN A BLUE CONTAINER THAT IS CLEARLY

MARKED “KEROSENE”. NEVER STORE KEROSENE IN A RED CONTAINER.

Red containers are associated with gasoline.

NEVER store kerosene in the living space. Kerosene should be stored in a well ventilated place

outside the living area.

NEVER use any fuel other than 1-K kerosene (#1 fuel oil is an acceptable substitute.)

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 explosion or

uncontrolled flames.

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.

5. OVERVIEW OF HEATERS DESIGN

Fuel System: This heater is equipped with an

electric air pump that forces air through the air line

connected to the fuel intake and then through a nozzle

in the burner head. When the air passes in front of the

fuel intake it causes fuel to rise from the tank and into the burner nozzle. This fuel and air mixture

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

“Sure Fire Ignition: The electronic ignitor sends voltage to a specially designed spark plug.

The spark plug ignites the fuel and air mixture described above.

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:

A. Temperature Limit Control: This heater is equipped with a Temperature Limit Control designed

to turn off the heater should the internal temperature rise to an

unsafe level. If this device activates and turns your heater off it

may require service.

Once the temperature falls below the reset temperature you will be able to start your heater.

NOTE: For your safety the temperature limiting safety device built into this heater will

allow the heater to run continuously when the ambient temperature is below

80˚F/24˚C.

B. Electrical System Protection: This heaters electrical system is protected by a fuse mounted to the

PCB Assembly that protects it and other electrical components from

damage. If your heater fails to operate check this fuse first and

replace as needed.

C. 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.

6. FUELING YOUR HEATER

NEVER FILL THE HEATER FUEL TANK IN THE LIVING SPACE: FILL THE TANK

OUTDOORS.

DO NOT OVERFILLYOUR HEATER AND BE SURE HEATER IS LEVELED.

IMPORTANT NOTICE 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 the heater to burn off outside.

WARNING!!: NEVER REFILL HEATER FUEL TANK WHEN HEATER IS OPERATING

OR STILL HOT.

7. OPERATION

A.) VENTILATION

RISK OF INDOOR AIR POLLUTION/USE HEATER ONLY IN WELL VENTILATED AREAS.

Provide a fresh air opening of at least three square feet (2800 sq. cm) for each 100,000 BTU/Hr.

rating. Provide extra fresh air if more heaters are being used.

Example: A DFA170Theater 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)

B.) OPERATION

TO START HEATER

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

2. Attach fuel cap.

3. Plug power cord of heater into three-prong, grounded extension cord. Extension cord must

be at least six feet long.

Extension Cord Wire Size Requirements

• 6 to 10 feet (1.8 to 3 meters) long, use 18 AWG conductor.

• 11 to 100 feet (3.4 to 30.5 meters) long, use 16 AWG conductor.

• 101 to 200 feet (30.8 to 61 meters) long, use 14 AWG conductor.

4. Turn “THERMOSTAT CONTROL Knob” to desired setting (DFA170T) and push power switch

to “ON” position, power indicator lamp will light and heater will start. If heater does not start,

the thermostat 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 8 and 9). If heater still does not start, see Troubleshooting Guide on page 13.

NOTE: For your safety the temperature limiting safety device built into this heater will allow the

heater to run continuously when the ambient temperature is below 80˚F/24˚C.

NOTICE:The major electrical components of this heater are protected by a safety fuse mounted to

the PCB board. If your heater fails to start, check this fuse 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. 8

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

NEVER mix water with the 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 months for use during next heating season.

Using old fuel could damage heater.

- Reinstall fuel cap. Properly dispose of old and dirty fuel.

- Store heater in dry well ventilated area. Make sure storage place is free of dust and corrosive fumes.
