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 thermo-
couple 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. (Rum
-
bling noise and flutter
-
ing 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.
