REMOVE THE HEATER AND ALL PACKING

MATERIALS FROM THE BOX.( Fig. 2 )

NOTE : Save the shipping carton and packing materials

for future storage.

CAUTION : DO NOT operate heater without heat

shield assembled to the heater.

The heat shield must attached to prevent any damage,

discoloration, or deformation to the floor.

NOTE : Heater should be inspected before each use, and at least annually by a qualified service person.

4. FUELS

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

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 an 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.

use any fuel other than 1-K kerosene (#1/#2 diesel/fuel oil, JET A or JP-8 fuels are acceptable substitutes)

For optimal performance of this heater, it is strongly suggested that 1-K kerosene be used. 1-K kerosene has

been refined to virtually eliminate contaminants, such as sulfur. Which can cause a rotten egg odor during the

operation of the heater. However, #1/#2 diesel/fuel oil, JET A or JP-8 fuels 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. #2 diesel/fuel oil heavier than 1-K kerosene in extreme cold temperatures without nontoxic anti-icer

additives will not ignite properly. When diesel fuel is used for this heater, small amount of smoke may occur at

the ignition and turn off time.

5. OVERVIEW OF HEATERS DESIGN

The Fuel System :

This heater is equipped with a high-pressure electronic pump. The pump draws fuel up from the fuel tank to

the nozzle in the burner head. It is sprayed into the combustion chamber in a fine mist where it is mixed

with air for combustion.

The Air System :

A blower motor assembly forces air around the combustion chamber, where it is super-heated and forced

out the front of the chamber. A cooling fan blows air up and around the chamber during operation and also

runs during the cool-down period.

The Ignition System :

The electronic ignitor sends High voltage to a specially designed Spark Plug.

The Spark Plug ignites the fuel and air mixture described above.

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.

B. Electrical System Protection : The heater's electrical system is protected by a fuse mounted to the

PCB assembly that protects the system components from damage.

If the heater fails, check the fuse first, and replace if necessary.

C. Flame-Out Sensor : The heater uses photocell to see the flame in the combustion chamber.

Should the flame extinguish, the sensor will stop electrical current and the

heater will shut off.

D. Shock(earthquake) automatic shut-off Device : This Heater is equipped with Tip Over switch,

In case that earthquake more than 5magnitude happens

or that heater inclined 5~10 degrees.

Heater will be shut-off by Tip Over switch for safety.

6. FUELING YOUR HEATER

NEVER FILL THE HEATER FUEL TANKIN THE LIVING SPACE: FILL THE TANK OUTDOORS.

DO NOT OVERFILL YOUR 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 TANKWHEN HEATER IS OPERATINGOR STILL HOT.

NEVER LEAVE THE HEATER

UNATTENDED WHILE BURNING!

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 (2,800 sq. cm) for each 100,000 BTU/Hr.

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

Example : A SF70DGD 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 fifteen inches (38.1 cm)

B.) OPERATION

TO START HEATER

1. Fill the tank with kerosene until needle on fuel gauge points to "F".

2. Be sure fuel cap is secure.

3. Plug power cord into three prong, grounded extension cord into three prong 120V grounded outlet.

The extension cord should be at least six feet long.

Extension cord wire size requirements are as follows:

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

• 11 to100 feet (3.4 to 30.4 meters ), use 16 AWG wire.

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

4. Push the Operating Switch to the "ON" position. The power indicator lamp will light

and the heater will ignite after the fan runs for a while. (approx.14sec.)

NOTE : The electrical components of this heater are protected by a fuse mounted in the PCB board.

If the heater fails to fire, check this fuse first, and replace if necessary. Also check the power

source to be sure that the proper voltage is being provided to the heater.

NOTE : In case of the following occurrences:

- Heater exhibits abnormal sputtering sound in the electronic pump while attempting to ignite.

- After filling up of the fuel tank, heater fails to properly ignite during its initial attempt.

- When user attempts to ignite heater following a previously failed ignition attempt with an

empty fuel tank.

- When the flow of fuel is blocked by air that is residing within the fuel line, in these cases,

one should try multiple ignition attempts on their heater.

The occurring noise is a direct result of the heating process as the heater’s pump pushes air

from the fuel line.

The noise should quickly decrease following the ignition of your heater.

It is also not unusual for slight smoke or flames to briefly be seen from the hot air outlet

after heater has ignited.

TO STOP HEATER

1. Turn the Operating Switch to "OFF" position. Combustion will stop, and the Cooling Cycle

(approx. 7 minutes) will begin.

2. When cooling Cycle is completed (fan stops running), it is safe to unplug the heater.

• Unplugging the heater before the Cooling Cycle has ended may cause overheating,

damage to the heater, and could void the warranty.

8. LONG TERM STORAGE OF YOUR HEATER

• Unscrew fuel cap.

• Remove Kerosene from the tank by using an approved siphon pump.

• Rinse and swirl the kerosene inside the fuel tank by using a small amount of kerosene.

• Make sure the tank is completely empty.

Never leave kerosene in the tank over a long period time because using old kerosene can damage the heater.

9. MAINTENANCE

• Be sure that the storage area is free of dust and corrosive vapors. Repack the original shipping material.

keep the User's Manual in an easily accessible place.
