Problem
Low heat / Low flame when
valve turned to high.
Burners burn with yellow
flame, accompanied by the
smell of gas.
Burner will not light with the
igniter, but will light with a
match.
Burner will not stay lit when
control knob is released.
Humming regulator.
Burner output on "high"
setting is too low. (Rumbling
noise and fluttering blue
flame at burner surface.)

Possible Causes
For propane - improper lighting
procedure.
For natural gas - undersized supply
line.
Possible spider web or other debris.
Dead battery / or installed incorrectly.
Loose electrode wire or switch
terminal wires.
Improper gap at electrode tip.
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.
Normal occurrence on hot days.
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.
Solution
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.
Thoroughly clean burner venturi. See general
maintenance instructions.
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.
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.
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.
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.
