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, but
there 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 tempera ture.
This heater should not be operated with
a tank smaller than 100 pounds.
Average
Temperature (°F)
at Tank Location
40
32 Use larger tank
20 Use larger tank
10 Use larger tank
0 Use larger tank
-10 Use larger tank
-20 Use larger tank
As the tempera ture 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.
