Corrective Action
Check the spark at the electrode and
pilot. If no spark and electrode wire is
properly connected, replace the ignitor.
Using a match, light the pilot. If the pilot
lights, turn off the pilot and trigger the
red piezo button again. If the pilot lights,
an improper gas/air mixture caused the
bad lighting and a longer purge period is
recommended. If the pilot will not light,
ensure that the gap at the electrode and
pilot is one-eighth
(1/8) inch to have a strong spark. If the
gap is OK, replace the pilot.
Check the remote shut-off valves from
the fireplace. Usually, there is a valve
near the gas main. There can be more
than one (1) valve between the fireplace
and the main.
Check the LP (propane) tank. You may
be out of fuel.
Check that the pilot flame impinges on
the thermocouple. Clean and/or adjust
the pilot for maximum flame
impingement.
Ensure that the thermocouple
connection at the gas valve is fully
inserted and tight (hand tighten plus
1/4 turn).
Disconnect the thermocouple from the
valve, place one millivolt meter lead
wire on the tip of the thermocouple and
the other meter lead wire on the
thermocouple copper lead. Start the
pilot and hold the valve knob in. If the
millivolt reading is less than 15mV,
replace the thermocouple.
If thermocouple is producing more than
15 millivolts, replace faulty valve.
Check the ON/OFF switch and wires for
proper connections. Place the jumper
wires across the terminals at the switch.
If the burner comes on, replace the
defective switch. If the switch is OK,
place the jumper wires across the
switch wires at the gas valve. If the
burner comes on, the wires are faulty or
connections are bad.
If the pilot flame is not close enough
physically to the thermopile, adjust the
pilot flame.
Be sure the wire connections from the
thermopile at the gas valve terminals
are tight and that the thermopile is fully
inserted into the pilot bracket.
Symptom
1. After repeated
triggering of the red
piezo button, the
spark ignitor will not
light the pilot.
2. The pilot will not stay
lit after carefully
following the lighting
instructions.
3. The pilot is burning,
there is no gas
burner, the valve
knob is in the ON
position, and the ON/
OFF switch is in the
ON position.
Possible Cause
a. Defective ignitor
b. Defective pilot or
misaligned electrode
(spark at electrode)
c. No gas or low gas
pressure
d. No LP in the tank
a. Defective
thermocouple
b. Defective valve
a. ON/OFF switch or
wires defective
b. Thermopile may not
be generating
sufficient millivoltage
