Operating Instructions and Parts Manual
• The electrical connection & grounding
must comply with National Electrical
Code. ANSI/NFPA 70 or in Canada CSA
C22.1, Canadian Electrical Code, Part 1.
Use only a properly grounded three (3)
prong receptacle.
• Do not restrict inlet or outlet by any
means. The flow of combustion and
ventilation air is not to be obstructed.
• This heater should not be directed
toward any propane-gas container
within 20 ft (6 m). The heater must be
located at least 6 ft. (1.83 m) in the U.S.;
or (ii) 10 ft. (3 m) in Canada, from any
propane gas container.
• The propane cylinder supply system
must be arranged to provide for vapour
withdrawal from the operating cylinder.
• This heater is not to be used with
external thermostats, timers or other
devices that control or alter electrical
supply to the heater.
• Installation of this Appliance at
altitudes above 2000 ft. (610 m) shall be
in accordance with local codes, or
in the absence of local codes the,
National Fuel Gas Code, ANSI Z223.1 /
NFPA 54, or National Standard of
Canada, Natural Gas and Propane
Installation Code, CSA B149.1.
Motor and fan must be
running before lighting,
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 tempera ture.
This heater should not be operated with
a tank smaller than 100 pounds.

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.
VENTILATION
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
Devices and Equipment ANSI A10.10,
ANSI 223.1 / NFPA 54, Liquified
Petroleum Gas Code, NFPA 58 or the
National Gas and Propane Installation
Code, CAN B149.1 as appropriate.
