• LP cylinders must be marked in
accordancewith“Cylinders,Spheres
and Tubes for Transporation of
DangerousGoods,CAN/CSAB339”.
• Use only LP-gas cylinders marked in
accordance with the U.S. Dept. of
Transportation (DOT).
• Use only 16.4 oz. (1 lb.) disposable
cylinders that mate with No. 600 valve
connection.
• Heater and attached cylinder must
be in an upright position during
operation.
1. Screw 1 lb. disposable LP-gas supply
cylinder clockwise (from bottom) into
portable heater until hand-tight and fit
cylinder into stand. Do not use thread
sealant on this connection. Be sure
cup adapter fits tightly into cup holder
before moving.
2. Check cylinder connection for leaks
with soapy water at the threaded
connection under the domed plastic
cover where the cylinder screws into
the regulator. SEE WARNING! ON
PLASTIC COVER.

gasoline and other flammable vapors
and liquids.
• Keep the vent areas (slots in the
bottom and top of the heater) clear at
all times.
Pilot Flame
Oxygen Depletion
Sensor
Figure 1
• 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.4) 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. 3)
and orifice (ref. 8) by using a vacuum
or compressed air (max 30 psi).
5. Inspect and clean pilot tube (ref. 7).
Insert a doubled over pipe cleaner
into the pilot tube until it bottoms
against the pilot orifice (approximately
