NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING! NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING! NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING!
IMPORTANT: The heater and its
surroundings should be kept clean and
free of dust.
• Visually inspect the pilot flame and
burner periodically during use. The
pilot flame should be blue in color
(not yellow) and will extend to the
thermocouple. The flame will surround
the thermocouple just below the tip.
See Figure 6.
• A slight yellow flame may occur where
the pilot flame and main burner
flame meet. The burner should be
bright orange (with a slight blue color
around the border, a red-orange haze
that is visible on the ceramic tile is
acceptable) and without a noticeable
flame.
• A blue flame that rolls out at the
top of the ceramic tile indicates an
accumulation of dust, lint or spider
webs inside the housing assembly and
main burner assembly. If the pilot is
yellow or the burner has a noticeable
flame, cleaning may be required.
• It is necessary to periodically check the
burner orifice and burner venturi to
make sure that they are clear of things
such as insect nests and spider webs
that may accumulate over time. A
clogged tube can lead to a fire.
• Use the following procedure to inspect
the casing assembly and main burner
assembly.

7. Inspect and clean pilot
(mounted to bracket) by using
a vacuum or apply air pressure
through the holes in the pilot
indicated by the arrows in
Figure 6.
8. Apply air pressure (max. 30
psi.) into ceramic tile of burner
assembly and the venturi tube
to remove dust, lint or spider
webs.

OFFSEASON
• If the heater is to left "OFF" for a
considerable period of time, the
propane (LP) gas supply to the heater
should be turned off as close to the
gas source as possible. In the case
of portable use, the gas should be
turned off at the propane (LP) gas
supply cylinder.
• If the heater is put into storage, make
sure to disconnect the propane (LP)
gas cylinder.
• When the LP-gas cylinder is not
disconnected from the heater, the
heater and cylinder must be located
outdoors, in a well-ventilated space,
out of the reach of children, and must
not be stored in a building, garage, or
any other enclosed area.
• Storage of the heater indoors is
permissible only if the cylinder is
disconnected and removed from
