SAFETY INFORMATION

A WARNINGS

IMPORTANT: Read this Owner's Manual carefully and completely before trying to assemble, oper-

ate, or service this heater. Im- proper use of this heater can

cause serious injury or death from burns, fire, explosion, electrical shock, and carbon monoxide

poisoning.

_k 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, alco-

hol, 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 fu-

eling of heating units.

b) Only the type of rue| specified on the

heater's data plate shall be used.

c) All flame, including the pilot light, if

any, shallbeextinguished andthe 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 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 pen- etrations 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 vapors

are present.

• Follow all local ordinances and codes when using heater.

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. It is further rec- ommended that these enclosure materi-

als be of a fire retardant nature. These enclosure materials shall be securely fas- tened 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 heaterproduces carbon monoxide, which is listed by the State of California as a reproductive toxin under Proposition 65.

Use only in places free of flammable va-

pors or high dust content. Use only the electrical voltage and fre-

quency specified on model plate.

Use only a three-prong, grounded exten- sion cord.

Minimum heater clearances from com- bustibles:

Outlet: 8 Ft. Sides: 4Ft.

Top: 4 Ft. 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 spillage

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 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.

• Approved by the New York City Fire Department under certificate of approval

#4803, #4860, #4908, or #4909. To be

Hammer

1. Slide axle through wheel support frame. Install wheels on axle.

IMPORTANT'When installing wheels,

point extended hub of wheels toward wheel support frame (see Figure 1).

Place cap nuts on axle ends. Gently tap with hammer to secure.

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 sup-

port frame. Place front handle (and rear handle if provided) on top of fuel tank flange.

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: Themotor turns 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 in the com- bustion chamber.

The Flame-Out Control System: This system causes the heaterto shut down if the

flame goes out.

FUELS

_,WARNING: Use only kerosene or No. 1fuel oil toavoid risk of fire

or explosion. Never use gaso- line, naphtha, paint thinners, al- cohol, 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

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 you to clean fuel system often.

VENTILATION

_lb Follow the minimum fresh, outside air ventilation require-

ments. If proper fresh, outside air ventilation is not provided, car-

bon monoxide poisoning can occur. Provide proper fresh, out-

side air ventilation before run-

ning heater.

Provide at least a three-square-foot opening of fresh, outside air for each i 00,000 Btu/Hr

rating. Provide extra fresh air if more heat- ers are being used.

Examp/e: A 115,000 Btu/I-lr heater re-

quires one of the following:

• a two-car garage door (16 feet wide open- ing) raised three inches

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

two 30 inch wide windows raised 8 _/2 inches

Safety Information section, page

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

codes when using this heater.

TO START HEATER

I. Follow all ventilation and safety infor-

mation.

2. Fill fuel 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 Re- quirements

• 6 to 10 feet long, use 18 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. Nolo: 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 from outlet and wait 10 seconds (two minutes if heater

has been running).

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

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

STORING, TRANSPORTING,

OR SHIPPING

Nolo: If shipping, transport companies re-

quire fuel tanks to be empty.

1. Drain fuel tank.

Note: This model has a drain plug on underside of fuel tank. Remove drain

plug to drain all fuel. Be sure all fuel is removed.

2. Replace drain plug.

3. If any debris is noted in old fuel, add i or 2 quarts of clean kerosene to tank, stir, and drain again. This will prevent

excess debris from clogging filters dur-

ing future use.

4. Replace fuel cap and drain plug. Prop- erly 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: Do not store kerosene over summer months for use during next heating season. Using old fuel could damage heater.
