SAFETY

INFORMATION

,_ 1WARNINGS

IMPORTANT: Read this Owner's Manual carefully and completely

before trying to assemble, oper- ate,orservicethisheater. Improper

use of this heater can cause seri- ous 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 re-

semble 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 preg-

nant 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 or No. 1 fuel oil to avoid risk of fire or explosion. Never use gasoline, naphtha, paint thinners, al- cohol, 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 lo- cal 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 tocool, 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 in- side 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 from heaters, torches, welding equipment, and

similar sources of ignition (excep- tion: 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 federal, state, or local au- thority having jurisdiction.

Never use heater where gasoline, paint thinner, or other highly flammable va- pors are present.

Follow all local ordinances and codes when using heater.

Heaters used in the vicinity of tarpau- lins, canvas, or similar enclosure ma- terials shall be located a safe distance

from such materials. The recommended minimum safe distance is 10 feet. It is further recommended that these enclo- sure materials be of a fire retardant na- ture. These enclosure materials shall be

securely fastened to prevent them from

igniting or from upsetting the heater

due to wind action.

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

This heater produces carbon monox-

ide, which is listed by the State of Cali- fornia as a reproductive toxin under

Proposition 65. Use only in places free of flammable

vapors or high dust content.

Use only the electrical voltage and fre- quency specified on model plate.

Use only a three-prong, grounded ex- tension cord.

Minimum heater clearances from

combustibles: Outlet: 8 Ft. Sides: 4 Ft.

Top: 4Ft. Rear: 4 Ft. Locate heater on a stable and level sur-

face if heater is hot or running or a fire

may occur.

When moving or storing heater, keep heater in a level position or fuel spill-

age may occur. Keep children and animals away

from heater. Unplug heater when not in use.

When used with thermostat, heater may start anytime.

Never use heater in living or sleep- ing 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.

THEORY OF OPERATION

The Fuel System: The air pump forces

air through the air line. The air is then pushed through thenozzle. This aircauses

fuel to lift from the tank.A finemist of fuel is sprayed into the combustion chamber.

The Air System: The motor tarns thefan. 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 con-

trol assembly provides power to the ignitor. This ignites the fuel/air mixture inthe com-

bustion chamber.

The Flame-Out Control System: This

system causes the heater to shut down if the flame goes out.

FUELS

_WARNING: Use only kerosene or No. 1 fuel oilto avoid risk offire

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 a clogged fuel filter and/or nozzle.

IMPORTANT: Use a KEROSENE ONLY storagecontainer. Be sure storagecontainer is

clean. Foreign matter such as rest, dirt, or water will causethe ignitioncontrol assembly to shut down the heater. Foreign matter may also require you to clean fuel system often.

VENTILATION

_[_ WARNING: Follow the mini- mum fresh, outside air ventila-

tion requirements. If proper fresh,

outside air ventilation is not pro-

vided, carbon monoxide poison-

ing can occur. Provide proper

fresh, outside air ventilation be- fore 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 heat- ers are being used.

Example: A 60,000 BttffHr heater requires

one of the following:

• a two-car garage door (16 feet wide open-

ing) raised i th"inches

• a single-car garage door (9 feet wide

opening) raised 2 _/z" inches

• two windows (30 inches wide opening)

raised 4 t/.,- inches

OPERATION

41& WARNING: Review and un- derstand the warnings in the

Safety Information section, page

2. They are needed to safely op- erate this heater. Follow all local

codes when uslng this heater.

TO START HEATER

1. Follow all ventilation and safety information.

2. Fill fue! tank with kerosene or No. 1 fuel oil.

3. Attach fuel cap.

4. Plug power cord of heater into three- prong, grounded extension cord. Exten- sion cord must be at least six feet long.

Extension Cord Wire Size Requirements

• 6 to 10 feet long, use i8 AWG rated

cord

• 11 to 100 feet long, use 16 AWG rated cord

• 101 to 200 feet long, use 14 AWG rated cord

Plug extension cord into standard 120 volt/60 hertz, three-hole, grounded out-

let. Note: Ignitor will preheat for five seconds then heater will start.

TO STOP HEATER

Unplug extension cord from outlet.

TO RESET HEATER

1. Unplug extension cord fromoutlet and wait 10 seconds (two minutes if heater

h_t_en running).

2. Plug extension cord into standard 120 volt/60 hertz, three-hole, grounded out-

let. Note: Ignitor will preheat for five seconds then heater will start.

STORING, TRANSPORTING,

OR SHIPPING

Note: If shipping, transport companies re- quire fuel tanks to be empty.

1. Drain fuel tank. Drain fuel through fuel cap opening. Be sure all fuel is removed.

2. 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 dur-

ing future use.

3. Replace fuel cap. Properly dispose of old and dirty fuel. Check with local auto- motive service stations that recycle oil.

4. If storing, store heater in dry place.

Make sure storage place is free of dust

and corrosive fumes.

IMPORTANT: Do not store kerosene over summer months for use during next heating

season. Using old fuel could damage heater.
