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
