Broken spark electrode -Check for broken ceramic insulation

Miss-aligned spark electrode -If spark is not arcing from the electrode to pilot-

Pilot will not remain lit Problem with thermocouple circuit -Check for proper connection of thermocouple

Air in gas line - (Pilot flame dies while

Burners will not remain lit Problem with thermopile circuit -Check gasline pressure.

Flame lifting - Leak in vent pipe

insufficient air for combustion - Air tight house

Glass fogs up Normal conditions - after the appliance warms up glass will clear

Blue flames
Flames are burning “dirty” or Sooting Flame impingement -check log position

Defective piezo ignitor Check connections to ignitor

-If ignitor connections are good but there is no
spark-replace ignitor
