MILLIVOLT STANDING PILOT IGNITION
TROUBLESHOOTING
SYMPTOM POSSIBLE CAUSE ACTION
1. Spark ignitor will not light
pilot after repeated trig-
gering of piezo.
A. Wire disconnected.
B. Defective ignitor.
C. No gas or low gas pres-
sure.
D. No Propane/LPG in
tank
A. Open door and check to make sure wire is connected
to ignitor.
B. Check for spark at electrode and pilot. If no spark
and electrode wire is properly connected, replace
the ignitor.
C. Check remote/manual shut off valve from fireplace.
Low pressure can be caused by bent lines, restricted
lines, low pressure line pressure. Consult with
plumber or gas supplier.
D. Check Propane/LPG tank. Refill tank.
2. Pilot will not stay lit after
carefully following lighting
instructions.
A. Defective thermocouple
B. Defective valve
A. Check that thermocouple flame impinges on ther -
mocouple. Clean and/or adjust pilot for maximum
flame impingement. Ensure that the thermocouple
connection at the gas valve is fully inserted and tight.
Disconnect the thermocouple from the valve, place
one millivolt 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 15 mV, replace
pilot assembly.
B. If thermocouple is producing more than 15 mV,
replace faulty valve.
3. Pilot burning, valve knob
turned to “ON,” switch is
turned to “ON,” but burner
will not ignite.
A. Defective switch, wall
switch, remote control
or wire
B. Pilot flame too small
C. Defective or malfunc-
tioning thermopile
D. Defective valve
A. Check switch and wire for proper connection. Place
jumper wires across terminals of switch. If burner
comes on, replace defective switch. If the switch is
OK, repeat the same procedure on remote control If
burner comes on, replace remote control.
Place jumper wire across wire at gas valves (termi-
nals marked TH and TP/TH). If burner comes on,
wires are faulty or connections are bad. Replace wire.
B. If pilot flame is not close enough to the thermopile,
adjust pilot flame.
C. Check thermopile wire connections to make sure
all are tight and that the thermopile is fully inserted
into pilot assembly. Check thermopile with a millivolt
meter. Connect leads to TP and TP/TH terminals on
the control valve. If meter reading is below 325 mV,
replace pilot assembly.
D. Turn valve knob to “On” and switch to “ON.” Take a
reading at the thermopile leads (TP & TP/TH) on the
valve. If the meter reads greater than 175 mV and
the burner does not light, replace defective valve.
4. Frequent pilot outage
problem.
A. Pilot flame may be too
high or too low, causing
pilot safety to drop out
A. Clean and adjust the pilot flame for maximum flame
impingement on thermocouple.
