Safety Information
This is a kerosene, direct-fired, forced air heater. It is pri-
marily intended for use for temporary heating of buildings
under construction, alteration or repair. Direct-fired means
that all of the combustion products of the heater enter the
heated space. This appliance is rated at 98% combustion
efficiency, but does produces small amounts of carbon
monoxide. Carbon monoxide is toxic. Humans can tolerate
small amounts of carbon monoxide, and precautions
should be taken to provide proper ventilation. Failure to
provide proper ventilation in according to this manual can
result in death. Early signs of carbon monoxide poisoning
resemble the flu. Symptoms of improper ventilation are:
*
headache
*
dizziness
*
burning of the nose and eyes
*
nausea
*
dry mouth or
*
sore throat
If the heater is being used in the presence of others, be
sure to inform them of all proper safety precautions, oper-
ating procedures and hazards. Some people are more
affected by carbon monoxide than others. These are preg-
nant women, people with heart or lung disease or anemia,
those under the influence of alcohol or at high altitudes.

Theory of Operation
Fuel System: This heater is equipped with an air pump
that operates off of the electric motor. The pump forces air
through the air line connected to the fuel tank, drawing fuel
to the nozzle in the burner head. Air also passes through
the nozzle where it mixes with the fuel and is sprayed into
the combustion chamber in a fine mist.
Quick-Fire Ignition: A transformer sends high voltage to a
two pronged spark plug. The spark ignites the fuel/air mix-
ture as it is sprayed into the combustion chamber.
Air System: A fan is turned by the heavy duty motor,
which forces air around and into the combustion chamber,
where it is super-heated and forced out the front of the
chamber.
Electrical System Protection: The heaters’ electrical sys-
tem is protected by a circuit breaker that protects the sys-
tem components from damage. If the heater fails, check
the fuse first, and replace if necessary.
Flame Sensor: The heater uses a photocell to “see” the
flame in the combustion chamber. Should the flame extin-
guish, the sensor will stop electrical current and the heater
will shut off.
Never leave heater
unattended while burning,
or while connected to a
power source

Danger: Carbon Monoxide poisoning may
lead to death!
Check the heater thoroughly for damage before each
use. DO NOT operate a damaged heater.
DO NOT modify this heater or operate a heater that
has been modified from it’s original state.
Use only K-1 kerosene or #1 fuel oil. Be advised that
diesel fuel may also be used, but because of the addi-
tives contained in diesel fuel, increased ventilation will
be required to disperse the added contaminants pro-
duced.
Additional maintenance to heater will also be
required.
NEVER use gasoline, naphtha, paint thinner, alcohol or
other fuels of any kind to operate this heater
.
For outdoor use, and indoor use only in well ventilated
areas. Provide at least 3 square feet of opening per
100,000 Btu of rated operation.
NEVER use heater in occupied dwellings.
Operate heater in a manner that will not directly expose
it to water, rain or dripping water.
Keep heater area free from combustible materials such
as gasoline, paint thinners and other flammable vapors
and liquids. Dust is combustible. Do not use heater in
areas of high dust concentration.
Operate only on level and stable surfaces.
Do not restrict inlet or outlet of heater. Heater is never
to be used with ductwork.
NEVER leave heater unattended.
Keep children and animals away from heater.
To prevent injury, always wear gloves when handling
heater. Never handle an operating or hot heater, as
severe burns may result.
This heater is not for use on finished floors.
Use heater in accordance to local codes and Federal
Ordinances.
Use only the electrical/power cord specified. Electrical
and grounding connection must comply with National
Electrical Code - ANSI/NFPA 70 (USA) and CSA C22.1
Canadian Electrical Code, Part 1 (Canada).
