Troubleshooting
Problem
Possible Causes
Solution
Low heat / Low flame
when valve turned on.
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 stay lit . Too windy.
Unit will shut down if winds are
greater than 10mph (16km/h).
Either locate to different area or use
when it is less windy.
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.
