Troubleshooting
Problem Possible Causes Solution
Low heat / Low flame when
valve turned to high.
For propane - improper lighting
procedure.
For natural gas - undersized supply
line.
Ensure lighting procedure is followed carefully. The
valve must be in the off position when the tank valve is
turned on. Turn tank on slowly to
allow 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 spider web or other debris. Thoroughly clean burner venturi. See general
maintenance instructions.
Burner will not light with the
igniter, but will light with a
match.
Dead battery / or installed incorrectly.
Loose electrode wire or switch
terminal wires.
Improper gap at electrode tip.
Replace with heavy duty battery.
Check that 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.
The gap can be adjusted by bending the tip in or out.
Until a spark is achieved.
Burner will not stay lit when
control knob is released.
Knob not being held in long enough.
Too windy.
Glass or debris in ignition area of the
burner preventing
thermocouple from being fully
engulfed in flame.
Dirty thermocouple or thermocouple
connection.
Faulty thermocouple or valve.
Thermocouple must have time to heat up – hold the
knob in for 30 seconds after the burner lights, then
release
Unit will shut down if winds are greater than 10mph
(16km/h). Either locate to different area or use when it
is less windy.
Ensure there is no glass or other debris in ignition area,
and that the small hole below the thermocouple is
unobstructed.
Clean the thermocouple and clean 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 gas heater.
Humming regulators will 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.
Spider webs or other matter in venturi
tube.
Propane regulator in “low flow” state.
Check gas level in propane cylinder.
Reposition supply hose as necessary.
Clean burner orifice.
Clean out venturi tube.
Ensure lighting procedure is followed carefully. All
valves must be in the off position when the tank valve
is turned on. Turn tank on slowly to allow pressure to
equalize. See lighting instructions.
