WARNING: Always inspect propane cylinder and heater
propane connections for damage, dirt, and debris before
attaching propane cylinder. Do not use if head of cylinder is
damaged, punctured or deteriorated.
ALWAYS ATTACH OR DETACH CYLINDER OUTDOORS
AWAY FROM FLAMES, OTHER IGNITION SOURCES, AND
ONLY WHEN HEATER IS COOL TO TOUCH. NEVER SMOKE
WHEN ATTACHING OR REMOVING PROPANE CYLINDER OR
MAKING REMOTE CONNECTIONS!
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.
Screw 1 lb. disposable LP-gas supply cylinder clockwise
(from bottom) into portable heater until hand-tight and
fit cylinder into stand.
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.
Depress "ON" button to light pilot flame (repeat until
pilot lights) and continue to hold for 30-60 seconds.
After lighting pilot, release "ON" button to light heater.
To shut off heater, press the "OFF" button.
cAutION: After turning heater off, wire guard will
remain hot. Allow to thoroughly cool before storing.
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 2.
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.

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 insects/
nests or spider webs that may accumulate over time. A
clogged tube can lead to a fire.
CLEANING INSTRUCTIONS:
1.
Allow heater to thoroughly cool before performing
any maintenance.
2. Remove disposable 1 lb. propane cylinder from
heater.
3. Remove right side plastic service panel (ref.5) by
removing the six screws holding it in place.
4. 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.
5. Inspect and clean main burner (ref. 13) and orifice
(ref. 3) by using a vacuum or compressed air (max 30
psi).
6. 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.
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.
7.
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.
8. Reinstall the right side plastic service panel.
