Problem Possible Cause Solution
Spark will not light the pilot after
repeated pressing of spark
igniter
Defective piezo igniter Check connections to igniter
-If igniter connections are good but

Broken spark electrode -Check for broken ceramic insulation
replace, electrode if broken
Miss-aligned spark electrode -If spark is not arcing from the
electrode to pilot- adjust by loosening
screws on pilot base. Adjust and re-
tighten
Pilot will not remain lit Problem with thermocouple circuit -Check for proper connection of
thermocouple to rear of valve. If loose,
tighten lightly
-Check pilot for full flame impingement
around thermocouple. If the pilot is to
small - Check gas pressure, adjust
pilot rate screw, check pilot head for
blockage.
-Check thermocouple voltage at valve-
must be greater than 5 mV. If low ,
replace thermocouple.
Air in gas line - (Pilot flame dies
while knob is depressed.)
-Bleed line.
-Check gas line pressure.
-Contact dealer.
Burners will not remain lit Problem with thermopile circuit -Check gas line pressure.
-Check for flame impingement on
thermopile, if low see “Pilot will not
stay lit”
-check thermopile for a Minimum of
300 mV when burner switched on.
-Check wiring to thermostat for breaks.
Flame lifting Leak in vent pipe
Improper vent configuration
Terminal may be recirculating flue
gases
-Check for leaks in vent connections
-Check vent configuration with manual
-Check to see if terminal is on correctly
-May need to install high wind
termination cap
-Contact dealer.

** Due to additives in gas, glass may get hazy during normal use**
Clean when needed.
Blue flames
Normal during start - flame will yello
w
the appliance heats up.
Flames are burning “dirty” or
Sooting
Flame impingement -Check log position
-Increase primary air by opening
venturi shutters

Flame goes out / comes on
frequently during a short period
of time
Improper placement of
thermostatic bulb
Move bulb to cooler location
