MAINTENANCE：
For enjoying years of outstanding performance of your appliance, make sure you adopt
the following maintenance tips on a regular basis:
• At least once a year, the unit should be inspected for spiders, cobwebs, or other
insects.
• Air flow must be unobstructed. Keep controls, burner, and circulating air passageways
clean. Signs of possible blockage include:
Gas odor with extremely tilted yellow flames.
Appliance does NOT reach the desired temperature.
Excessive unevenness of heat.
Popping sounds when heating.
• Spiders and insects can nest in burner or orifices. This dangerous condition can
damage appliance and render it unsafe for use. Clean burner holes using the liquid clog
remover.
Compressed air may help clear away smaller particles.
• Carbon deposits may cause a fire hazard. Clean reflector, thermocouple, and emitter
screen with a dry cloth if any carbon deposits develop.
• The burner is made of stainless steel, but extreme heat and a corrosive environment
can cause surface corrosion. Inspect the burner at least annually for cracks, insect nests,
excessive corrosion, or any other damage. If the burner is damaged, it must be replaced
by a burner specified by the manufacturer before the appliance is put into operation.

SOLUTION
Low heat / Low flame
when the valve is turned
to HIGH position.
PROBLEM PROBABLE CAUSE
Incorrect lighting operation. Ensure the lighting procedure is followed carefully. The valve
must be in the OFF position when the tank valve is turned on.
Turn the tank on slowly to allow the pressure to equalize. See
lighting instructions.
Pipe must be sized according to installation code.
Burners burn with yellow
flame, accompanied by
the smell of gas.
Possible cobwebs or other debris. Thoroughly clean the burner venturi. See general maintenance
instructions.
Burners are not lit by the
igniter, but are lit with a
match.
Loose electrode wire or switch
terminal wires.
Check whether the electrode wire is firmly pushed onto the
terminal on the back of the igniter. Check that the lead wires
from the module to the ignition switch (if equipped) are firmly
pushed onto their respective terminals.
Burners do not keep
burning when the control
knob is released.
The knob is not pressed long enough.
Too windy.
Lava glass or debris in ignition area of
the burner prevents thermocouple
from being fully engulfed in flame.
Dirty thermocouple or thermocouple
connection.
Incorrect thermocouple or valve.
Thermocouple needs time to heat up - Keep pressing the knob
for 30 seconds until the burner is lit, then release.
If the wind speed is faster than 10 mph (16 km/h), the unit will
shut off automatically. Either use it in another area where the
wind speed is low.
Ensure that there are no lava glass or other debris in the
ignition area, and that the small hole below the thermocouple is
unobstructed.
Clean the thermocouple and the connection between the valve
and thermocouple. Ensure the connection is properly tightened.
Replace thermocouple and / or valve.
Humming regulator. Normal occurrence on hot days. This is not a defect. It is caused by internal vibrations in the
regulator and does not affect the performance or safety of the
appliance.
Humming regulators need not be replaced.
Burner output on "HIGH"
setting is too low.
(Rumbling noise and
fluttering blue flame at
burner surface.)
Lack of gas.
Supply hose is pinched.
Dirty or clogged orifice.
Cobwebs or other substances
in the venturi tube.
Propane regulator in "low flow”
state.
Check the gas level of propane cylinder.
Reposition the supply hose to suit needs.
Clean the burner orifice.
Clean out the venturi tube.
Ensure the lighting procedure is followed carefully. All
valves must be in the OFF position when the tank valve
is turned on. Turn the tank on slowly to allow pressure
to equalize. See lighting instructions.
