WARNING: Turn off fireplace and let cool before servicing. Only

OBSERVED PROBLEM
Pilot will not stay lit
Pilot lit but no flame on
burner
Frequent pilot outage
POSSIBLE CAUSE
1. Defective thermocouple
1. Remote or wires defective
2. Thermopile not generating
sufficient millivoltage
3. Plugged burner orifice
1. Pilot flame may be too low
or blowing (high) causing
safety pilot to “drop out”
REMEDY
1. Check pilot flame. It must
impinge on thermocouple
2. Clean or adjust pilot for
maximum flame impinge
-
ment on thermocouple
3. Ensure connection between
valve and thermocouple are
tight and secure
4. Check thermocouple with
millivolt meter. Take reading
at thermocouple terminals
of gas valve with remote
control off. It should read
18 millivolts minimum. Re-
place faulty thermocouple if
reading is below specified
minimum
1. Check remote wires for
proper connections. Place
jumper wire across ter-
minals at remote control.
If burner comes on, re-
place remote. If okay, place
jumper wire across remote
control at valve. If burner
comes on, wires are faulty
or connections are bad
2. Check thermopile with mil-
livolt meter. Take reading at
thermopile terminals of gas
valve with remote control
off. It should read 325 mil-
livolts minimum. Replace
thermopile if reading is
below specified minimum
3. Check burner orifice for
stoppage and remove
1. Clean and/or adjust pilot
flame for maximum flame
impingement on thermo-
couple
