MONOXIDE POISONING.
This is a direct-fired forced air
construction heater for either indoor
construction or outdoor use. Its
intended use is primarily the temporary
heating of buildings or structures under
construction, alteration or repair. All
the products of combustion generated
by the heater are forced through the
heater and released into the area
being heated. This heater operates
at approximately 98%+ combustion
efficiency but still produces a small
amount of carbon monoxide. Humans
can tolerate small amounts of carbon
monoxide for short periods. Carbon
monoxide can build up in a heated
space and failure to provide adequate
ventilation could result in poisoning or
death.
For either indoor or outdoor use.
Adequate ventilation shall be provided
in accordance with OSHA 29 CFR
1926.154, Safety Requirements for
Temporary and Portable Space Heating

during operation and at shutdown, in order
to prevent a flame-out condition which could
result in personal injury or property
damage.
• Do not adjust regulator below 7 PSIG
or above 10 PSIG
Theory of Operation
FUEL SYSTEM
The hose/regulator assembly runs from
the propane supply to the heater itself.
After the gas runs through the hose
and regulator, it passes through the
solenoid valve and out the nozzle into
the combustion chamber.
AIR SYSTEM
The internal motor turns the fan, which
pushes air around and through the
combustion chamber. Here the air is
heated and provides a constant stream
of warmth.
IGNITION SYSTEM
The spark module sends voltage to the
ignitor. The ignitor ignites the fuel and
air mixture.
SAFETY CONTROL SYSTEM
This system shuts the heater down
if the flame is extinguished. The fan
and motor will continue to operate,
butthere will not be any heat.
PROPANE SUPPLY
All propane gas and tanks are to be
provided by the user.
This heater should only be used with
a tank that has a vapor withdrawal
system. Refer to the Standard of
Storage and Handling of Liquefied
Petroleum Gas, ANSI/NFPA 58, Chapter
5. Your local fire department or library
will have this information.
Two factors will dictate how much
propane is used from each tank:
1. The amount of gas in each tank.
2. The surrounding air temperature at
each tank.
The chart below shows how many tanks
should be used at a given temperature.
This heater should not be operated with
a tank smaller than 100 pounds.

As the temperature drops, less gas is
vaporized, so a larger tank may be
necessary in very cold weather. Never
operate this heater with a tank smaller
than 100 pounds. Your local propane
dealer can help you select the proper
tank size and configuration.
VENTILATION
For either indoor or outdoor use.
Adequate ventilation shall be provided
in accordance with OSHA 29 CFR
1926.154, Safety Requirements for
