INFORMATION
WARNINGS
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 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 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 federal, state, or local 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.

from such materials. The recommended
minimum safe distance is 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.
• Use only in well-vented areas. Before
using heater, provide at least a threesquare-foot opening of fresh, outside
air for each 100,000 Btu/Hr of rating.
This heater produces carbon monoxide, which is listed by the State of California 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 frequency specified on model plate.
• Use only a three-prong, grounded extension cord.

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 nontoxic anti-icer in fuel during very cold weather
IMPORTANT:
storage container. Be sure storage container
is clean. Foreign matter such as rust, dirt, or
water will cause the flame-out control to
shut down heater. Foreign matter may also
require you to clean fuel system often.

VENTILATION
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.
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:
quires one of the following:
• a two-car garage door (16 feet wide opening) raised five inches
• a single-car garage door (9 feet wide
opening) raised eight inches
• two windows (30 inches wide opening)
raised fifteen inches

OWNER’S MANUAL
THEORY OF
OPERATION
The Fuel System: The air pump forces
air through the air line. The air is then
pushed through the burner head 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 electronic
ignitor sends voltage to the spark plug. The
spark plug ignites the fuel and air mixture.
The Flame-out Control System: This
system causes the heater to shut down if the
flame goes out.
