StaNDING pIlot IGNItIoN
SyMpTOM
1. Spark ignitor will
not light pilot after
repeated triggering of
piezo.
2. Pilot will not stay lit
after carefully follow-
ing lighting instruc-
tions.
3. Pilot burning, valve
knob turned to "ON",
switch is turned to
"ON" or "RS", but
burner will not ignite.

pOSSIbLE CAUSE
A. Wire disconnected.
B. Defective ignitor.
C. No gas or low gas pres-
sure.
A. Defective thermocouple
B. Defective valve
A. Defective switch, wall
switch, remote control or
wire
B. Pilot flame too small
C. Defective or malfunction-
ing thermopile
D. Defective valve
ACTION
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 pilot
assembly.
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.
A. Check that thermocouple flame impinges on thermo-
couple. 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.
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 (terminals
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 read-
ing 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.
