PROBLEM
TEST SOLUTION
Electrode sparks,
burner ignites,
electrode continues
to spark for
complete 7 seconds,
burner shuts down.
Hot and neutral wires are
reversed at control module.
Sensor /
fl
ame not
connecting
- Connect the hot wire to the black wire. Connect the neutral
wire to the white wire.
- Raise electrode / sensor up into
fl
ame 1/4” above the burner.
Flame length
consistently too
large or too small.
Carboning occurs.
Unit is over-
fi
red or under-
fi
red.
- Check pressure readings
- Outlet pressure can be checked by removing cap (A) and
replacing it with a 1/8” NPT barb
fi
tting. Next, place pressure
gauge tubing over the
fi
tting. Gauge should read 3.5” W.C.
for natural gas or 10.0” W.C. for propane. AFTER TAKING
PRESSURE READINGS, BE SURE TO REPLACE CAP TO
RESEAL. DO NOT OVER-TORQUE.
- Leak test with a soap and water solution.
Carbon is being
deposited on glass,
and combustion
chamber surfaces.
Air shutter has become
blocked.
- Ensure air shutter opening is free of lint or other obstructions.
Flame is impinging on the
combustion chamber.
- Open air shutter to increase the primary air.
- Check the input rate: check the manifold pressure and ori
fi
ce
size as speci
fi
ed by the rating plate values.
White / grey
fi
lm
forms.
Sulphur from fuel is being
deposited on glass, logs
or combustion chamber
surfaces.
- Clean the glass with a gas appliance glass cleaner.
DO NOT
CLEAN GLASS WHEN HOT.
If deposits are not cleaned off
regularly, the glass may become permanently marked.
No gas to the main
burner; switch is on.
Switch is defective.
- Connect a jumper wire across the wall switch terminals; if main
burner lights, replace switch.
Burner ori
fi
ce is blocked.
- Remove stoppage in ori
fi
ce.
Control valve faulty.
- Replace.
Faulty valve.
- Replace.
Burner will not light,
ignitor sparks.
No gas at the burner.
- Check that the manual valve is turned on.
- Replace the valve.
Out of propane gas.
- Fill the tank.
Electrode does not
spark. Burner does
not light.
GFCI has been tripped.
- Push reset button (red) on the face of the GFCI.
Ignitor
will
not
spark.
No spark at ignitor.
- Check the power source. (ie. fuse, circuit breaker, GFCI resent
button.)
- Check that the wire is connected to both the ignitor and the
control module.
- Check that the spark is not jumping to ignitor cover.
- Replace the wire if the wire insulation is broken or frayed.
- Replace the electrode if the ceramic insulator is cracked or
broken.
Spark gap is incorrect.
- Spark gap should be 0.125” (1/8” approx.) from the electrode
tip to the sensor tip.
Remote wall switch
is in “OFF” position;
burner comes on.
Wall switch is mounted
upside down.
- Reverse.
Remote wall switch is
grounding.
- Replace.
Remote wall switch wire is
grounding.
- Check for ground (short); repair ground or replace wire.
Faulty wire.
- Replace.
