TROUBLESHOOTING
The two most common causes of a malfunctioning gas appliance are:
1. Loose wiring connections
2. Construction debris clogging the pilot and/or gas control valve filter
OBSERVED PROBLEM
Pilot will not light
Pilot will not stay lit
No gas to burner, although wall switch and
valve are set to the ON position
Frequent pilot outage
POSSIBLE CAUSE
1. No gas supply, or shut-off valve is OFF
2. Air in gas line
3. Construction debris clogging pilot orifice
4. Low gas pressure
5. Control valve knob is not on the PILOT
position
6. Kinked pilot line
7. Bad valve
1. Loose wiring on thermopile to regula-
tor valve. No millivolt current is being
sent back to regulator
2. If valve knob and wall switch are in the
ON position, probable defective regula-
tor valve
1. Wall switch wires defective or too long
2. Powerpyle generator or sensor not gen-
erating sufficient voltage
1. Pilot flame may be too low, causing
safety pilot to “drop out”
REMEDY
1. Check to see if you have gas supply
2. Hold regulator control valve in the PILOT
position for 2 to 3 minutes to purge air. If
you smell gas stop and wait for a few min-
utes before trying to light the fireplace
3. Remove debris and dirt, inspect and
clean any other possible obstructions
4. Contact your gas supplier
5. Refer to section on pilot lighting
6. Have a qualified technician replace pi-
lot line
7. Replace regulator valve (see Accesso-
ries, page 18)
1. Check wiring connections. Refer to wir-
ing diagram shown in Wall Switch In-
stallation, page 8
2. Have a qualified technician replace valve
1. Check electrical connections
2. See Pilot will not stay lit, above
1. Clean and adjust pilot flame for maximum
flame impingement on thermopile
