TROUBLE SHOOTING
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
there is no spark-replace igniter
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
220 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.
Glass fogs up Normal conditions - after the appliance warms up glass will clear
** Due to additives in gas, glass may get hazy during normal use**
Clean when needed.
Blue flames
Normal during start - flame will yellow as the
appliance heats up.
Flames are burning “dirty” or
Sooting Flame impingement -Check log position
-Increase primary air by opening
venturi shutters
