SAFETY

INFORMATION

W ARNINGS

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, electrocution, and carbon monoxide poisoning.

DANGER

Carbon monoxide poisoning may lead to death!

Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning

resemble the ﬂu, with headaches, dizziness, or nausea. If you have these signs, the heater may not be working properly. Get fresh air at once! Have heater serviced. Some people are more affected by carbon monoxide than others. These include pregnant women, people with heart or lung disease or anemia, those under the influence of alcohol, and those at high altitudes.

WARNINGS

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.

• Fueling a) Personnel involved with fueling shall be qualified and thoroughly familiar with the manufacturer’s instructions and applicable federal, state, and local regulations regarding the safe fueling of heating units. b) Only the type of fuel specified on the heater’s data plate shall be used. c) All flame, including the pilot light, if any, shall be extinguished and the heater allowed to cool, prior to fueling. d) During fueling, all fuel lines and fuel-line connections shall be inspected for leaks. Any leaks shall be repaired prior to returning the heater to service. e) At no time shall more than one day’s supply of heater fuel be stored inside a building in the vicinity of the heater. Bulk fuel storage shall be outside the structure. f) All fuel storage shall be located a minimum of 25 feet (762 cm) from heaters, torches, welding equipment, and similar sources of ignition (exception: the fuel reservoir integral with the heater unit). g) Whenever possible, fuel storage shall be confined to areas where floor penetrations do not permit fuel to drip onto or be ignited by a fire at lower elevation. h) Fuel storage shall be in accordance with the authority having jurisdiction.

• 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 three square feet (2800 square cm) of fresh, outside air for each 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.

• Heaters used in the vicinity of tarpaulins, canvas, or similar enclosure materials shall be located a safe distance from such materials. The recommended minimum safe distance is 10 feet (304.8 cm). It is further recommended that these enclosure materials be of a fire retardant nature. These enclosure materials shall be securely fastened to prevent them from igniting or from upsetting the heater due to wind action.

• Minimum heater clearances from combustibles:

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

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

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

• Keep children and animals away from heater.

• Unplug heater when not in use.

• This heater has a built-in thermostat. Plugged-in heater may start at 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.

1. Remove all protective packing applied to heater for shipment.

2. Remove heater from shipping container.

3. Check heater for any shipping damage. If heater is damaged, promptly inform dealer where you bought heater.

ASSEMBLY

This model is furnished with wheels and front and rear handles. Wheels, handles, and mounting hardware are found in the shipping carton.

TOOLS NEEDED

• Pliers

• Two - 7/16" Open or Adjustable Wrenches

1. Slide axle through wheel support frame. Install wheel spacer and then one flat washer on each end of axle.

2. Install wheels on axle.

IMPORTANT:

When installing wheels, point exetended hub of wheels toward

wheel support frame (see Figure 2, page 5).

3. Slide one flat washer on each axle end in front of wheel.

4. Install cotter pins through holes at each end of axle. Bend cotter pins with pliers to secure.

5. Place heater on wheel support frame. Make sure air inlet end (rear) of heater is over wheels. Line up holes on fuel tank flange with holes on wheel support frame.

6. Place front and rear handles on top of fuel tank flange. Insert screws through handles, fuel tank flange, and wheel support frame. Attach nut finger tight after inserting each screw.

THEORY OF

OPERATION

The Fuel System: The motor turns the fuel pump. The fuel pump pulls fuel from

the fuel tank. The fuel pump pushes fuel through a ﬁlter and a solenoid valve and out the burner head nozzle. 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 Burner Control System: This system causes the heater to shut down if the flame goes out. It also allows the fan to continue running after normal shutdown of heater. This cools the combustion chamber.

FUELS

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.

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

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

VENTILATION

IMPORTANT:

container is clean. Foreign matter such as rust, dirt, or water will cause burner control to shut down heater. Foreign matter may also require fuel system to be cleaned frequently.

Use a KEROSENE ONLY storage container. Be sure storage

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.

Fresh Air Opening Requirements

Square Square

Heater Size Feet Opening Centimeter Opening

340,000 Btu/Hr 10.5 9755

Note:

If you use more than one heater, provide extra fresh air. Provide a fresh air

opening of at least three square feet (2800 square cm) for each 100,000 Btu/Hr rating.
