• The LP-gas cylinder(s) used must be
constructed and marked in accordance
with the specifications for LP-gas
cylinders of the U.S. Department of
Transportation (DOT).
• Use only VAPOR WITHDRAWAL
propane supply. If there is any
question about vapor withdrawal, ask
your propane dealer.
• Use only 16.4 oz. (1 lb.) disposable
cylinders that mate with No. 600 valve
connection.
• This heater consumes oxygen from the
room in which it is installed. To assure
complete combustion, an adequate
fresh air supply to the room, See
General Safety Instructions, Page 3.
• Heater and attached cylinder must
be in an upright position during
operation.
IMPORTANT: The heater must not be
exposed to flammable vapors or liquids
during lighting.
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.
IMPORTANT:Check cylinder connection
for leaks with soapy water at the
threaded connection under the domed
plastic cover where the cylinder screws
into the regulator. DO NOT USE ANY
EXPOSED FLAME TO CHECK FOR
LEAKS. DO NOT OVERTIGHTEN. SEE
WARNING! ON PLASTIC COVER.
2. Depress "ON" button to light pilot
flame (repeat until pilot lights) and
continue to hold for 30-60 seconds.
See Figure 1.
3. After lighting pilot, release "ON"
button to light heater.
Shutdown Instructions
1. To shut off heater, press the "OFF"
button. See Figure 1.
• Do not operate, store or remove
cylinder near flammable items or
ignition sources.
• LP-GAS CYLINDERS MUST BE

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.
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 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.
• 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.
