3. Depress "ON" button to light pilot
flame (repeat until pilot lights) and
continue to hold for 30-60 seconds.
4. After lighting pilot, release "ON"
button to light heater.
Shutdown Instructions
1. To shut off heater, press the "OFF"
button.
• Do not operate, store or remove
cylinder near flammable items or
ignition sources.
• LP-GAS CYLINDERS MUST BE
DISCONNECTED FROM HEATER WHEN
NOT IN USE!
Maintenance
• Always keep the heater area clear
and free from combustible materials,
gasoline and other flammable vapors
and liquids.
• Keep the vent areas (slots in the
bottom and top of the heater) clear at
all times.
• 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 1.
• 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. Use
the following procedure to inspect
the casing assembly and main burner
assembly. 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.

Cleaning Instructions (Refer to
Exploded Parts on Page 6):
IMPORTANT: Allow heater to
thoroughly cool before performing any
maintenance.
1. Remove disposable 1 lb. propane
cylinder from heater.
2. Remove right side plastic service panel
(ref.5) by removing the six screws
holding it in place.
3. Inspect the interior of casing for
accumulation of dust, lint or spider
webs. If necessary, clean the interior
of the casing assembly with a vacuum
cleaner or compressed air (max 30
psi). Do not damage any components
within the casing assembly when you
are cleaning.
4. Inspect and clean main burner (ref. 13)
and orifice (ref. 3) by using a vacuum
or compressed air (max 30 psi).
5. Inspect and clean pilot tube (ref. 14).
Insert a doubled over pipe cleaner
into the pilot tube until it bottoms
against the pilot orifice (approximately
2"). Rotate the pipe cleaner a couple
of times and remove. Blow out the
remaining debris using compressed air.
6. Apply compressed air (max 30 psi) into
the ceramic tile of burner assembly
and venturi tube (ref. 13) to remove
dust, lint and spider webs.
7. Reinstall the right side plastic service
panel.
8. The exterior of the heater can be
cleaned with a damp cloth. Avoid the
direct use of any aerosol or spray-on
cleaners. Do not use abrasive materials
or cleaners on the decals or control
knob.
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.

or deteriorated.
WARNING: Heater must not be
exposed to flammable vapors or liquids
during ignition or operation.
CAUTION: After turning heater off,
wire guard will remain hot. Allow to
thoroughly cool before storing.
WARNING: Never use needles, wires
or similar cylindrical objects to clean the
pilot to avoid damaging the calibrated
ruby that controls the gas flow through
the pilot orifice.
• 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
