SAFETY INFORMATION

WARNINGS

WARNING: This product contains and/or generates chemicals known to the State of California to cause cancer or birth defects, or other reproductive harm.

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.

DANGER: Carbon monoxide poisoning may lead to death!

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 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, #1#2 diesel/fuel oil, JET A or JP-8 fuels 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 thor-

oughly familiar with the manufacturer's instructions and applicable 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 extin-

guished 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 762cm (25

feet) 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 hav-

ing jurisdiction.

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

• Heater must be grounded. Use only a properly grounded threewire extension cord. Plug into grounded outlet only.

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

• Minimum clearance from any combustible materials: 8 feet (244 cm) from hot air outlet; 4 feet (122 cm) from top; and 4 feet (122 cm) from sides and inlet.

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

• Use only in well-vented areas. Before using heater, provide at least a 2800 square cm (three-square-foot) opening of fresh, outside air for each 30 kw (100,000 Btu/Hr) of rating.

• Keep children and animals away from heater at all times.

• Never start heater when combustion chamber is hot or if fuel has accumulated in combustion chamber.

• When used with thermostat, heater may start at anytime.

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

• Use heater only in accordance with local ordinances and codes.

• Never use gasoline, crankcase drainings, naphtha, paint thinners, alcohol, or other highly flammable fuels.

• Never use heater where gasoline, paint thinner, or other highly flammable vapors are present.

• Never use heater in living or sleeping areas.

• Never leave a heater plugged in without adult supervision if children or animals are likely to be present.

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

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

• Never attach heater to external fuel tank.

• 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

304.8cm (10 feet). 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.

• Unplug heater when not in use.

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

•

Warning to New York City Residents For Use Only At Construction Sites in accordance with ap-

plicable NYC codes under NYCFD certificate of approval #4803, #4899, #4908, #4909, or #4934.

THEORY OF OPERATION

FUELS VENTILATION

THEORY OF OPERATION

The Fuel System: The air pump forces air through the air line. The

air is then pushed through the 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 ignition control assembly provides power to the ignitor. This ignites the fuel/air mixture in the combustion chamber.

The Flame-Out Control System: This system causes the heater to

FUELS

WARNING: Use only kerosene, #1/#2 diesel/fuel oil, JET A or JP-8 fuels to avoid risk of ﬁre or explosion. Never use gasoline, oil drained from crankcases, naphtha, paint thinners, alcohol or other highly ﬂammable fuels.

Use only kerosene, #1/#2 diesel/fuel oil, JET A or JP-8 fuels. Heavier fuels such as No. 2 fuel oil or No. 2 diesel fuel may also be used but will result in:

• noticeable odor

• additional fuel ﬁlter maintenance

• the need for nontoxic, anti-icer additives in very cold weather Do not use fuels heavier than No. 2 grade or heavy oils such as oil

drained from crankcases. These heavy oils will not ignite properly and will contaminate the heater.

IMPORTANT:

(yellow) storage container. Be sure storage container is clean. Foreign matter such as rust, dirt, or water will cause the ignition control assembly to shut down the heater. Foreign matter may also require heater's fuel system to be frequently cleaned.

Use a KEROSENE ONLY (blue) or DIESEL ONLY

VENTILATION

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.

Provide at least a three-square-foot opening of fresh, outside air for each 100,000 Btu/Hr rating. Provide extra fresh air if more heaters are being used.

Example:

• a two-car garage door (16 feet wide opening) raised 3.5 inches

• a single-car garage door (9 feet wide opening) raised 6.5 inches

• two 30 inch wide windows raised 11.5 inches

A 155,000 Btu/Hr heater requires one of the following:

OPERATION WITH PORTABLE GENERATOR

PREVENTATIVE MAINTENANCE SCHEDULE STORING, TRANSPORTING, OR SHIPPING

OPERATION WITH PORTABLE GENERATOR

WARNING: Before operating heater or any appliance from a portable generator, verify that generator has been properly connected to earth ground. Improper grounding or failure to ground generator can result in electrocution if a ground fault occurs. Refer to owner’s manual supplied by generator manufacturer for proper grounding procedures.

The operating voltage range of the heater is 108 to 132 Volts (120 Volts +/- 10%). Prior to plugging heater into generator the output voltage should be verified (if generator is equipped with the automatic idle feature, the output voltage should be measured with the generator running at full speed). If the voltage does not measure in this range the heater should not be plugged into the generator.

Refer to Operation, page 5, for starting, stopping, and resetting heater procedures.

STORING, TRANSPORTING, OR SHIPPING

Note:

If shipping, transport companies require fuel tanks to be empty.

1. Drain fuel tank.

Note:

Some models have drain plug on underside of fuel tank. If so, remove drain plug to drain all fuel. If heater does not have drain plug, drain fuel through fuel cap opening. Be sure all fuel is removed.

2. Replace drain plug if provided.

3. If any debris is noted in old fuel, add 1 or 2 quarts of clean kerosene to tank, stir, and drain again. This will prevent excess debris from clogging filters during future use.

4. Replace fuel cap or drain plug. Properly dispose of old and dirty fuel. Check with local automotive service stations that recycle oil.

5. If storing, store heater in dry place. Make sure storage place is free of dust and corrosive fumes.

IMPORTANT:

during next heating season. Using old fuel could damage heater.

Do not store kerosene over summer months for use
