Issue
Cause
Solution
No spark from electrode to
pilot when piezo button is
triggered
Piezo igniter wiring disconnection
Verify piezo igniter is properly grounded. Tighten mounting fastener, if
required.
Check and repair, if necessary, the wire connections between the piezo
igniter and igniter electrode.
Check wiring disconnection
Check wiring at back of electrode igniter for proper connection.
Incorrect electrode position
Verify there is a 1/8” (3mm) gap between the electrode and pilot. Readjust
if necessary. Direct metal contact may cause an arc below the electrode
and along the electrode wire.
Spark igniter will not light
after repeated triggering of
piezo button
No gas
Check for multiple shut-off valves in the supply line.
Check propane tank for gas supply. Refill if necessary.
Pilot will not stay lit after
carefully following lighting
instructions
Pilot flame does not impinge on
thermocouple
Clean pilot hood
Adjust pilot flame at gas valve for proper flame impingement.
Loose thermocouple connection
Ensure thermocouple connection at gas valve is full inserted and tight -
hand tight plus 1/4 turn.
Thermocouple reading below 15
millivolts
Disconnect the thermocouple from valve. Place one millivolt meter lead
wire on the end of the thermocouple, and the other millivolt meter lead
wire on the thermocouple’s copper wire. Start the pilot while holding the
gas valve control knob in.
If the millivolt reading is less than 15 millivolts, replace thermocouple.
Thermopile not generating
sufficient millivolts
Adjust, if necessary, the pilot flame to envelop thermopile.
Check thermopile connections are properly wired to the gas control
valve. Tighten if necessary.
Measure millivolt production with a millivolt meter. Turn remote/
thermostat/wall switch, or ON/OFF rocker switch to OFF. Turn the gas
valve control to the PILOT position (pilot should remain lit).
Take millivolt reading at TH-TP and TP terminals on gas valve. Reading
should be 350 millivolts, minimum. If reading is less than 350 millivolts,
replace thermopile.
Frequent pilot outages
Pilot shield not installed
Install pilot shield.
Pilot safety dropout
Pilot flame is too high or too low. Clean pilot hood and adjust pilot flame
for maximum flame impingement on thermopile.
ATTENTION: Troubleshooting must be performed by a qualified
technician.
