Trouble Shooting
Problem Possible Cause Solution
Spark will not arc to the
pilot after repeatedly
pressing the spark ignitor
Defective piezo ignitor • Check connections to ignitor
• If ignitor connections are good but no spark, replace
ignitor.
Broken spark electrode • Check for broken ceramic insulation. Replace
electrode if broken.
Mis-aligned spark electrode • If spark is not arcing from electrode to pilot, adjust
by loosening the screws on the pilot base. Adjust and
tighten.
Pilot will not remain lit Problem with thermocouple
circuit
• Check for proper connection of the thermocouple to
the rear of the valve; if loose fully tighten.
• Check pilot for full ame impingement around
thermocouple. If ame is too small, check gas
pressure, adjust pilot rate screw, check pilot head for
damage.
• Check thermocouple voltage at valve. It must be
greater than 5mV. If low, replace thermocouple.
Air in gas line (pilot 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 ame impingement in thermopile. If low,
see “Pilot will not remain lit”.
• Check thermopile for minimum of 300mV when
burner is switched on.
• Check wiring to thermostat for breaks
BV ONLY:
•Check for spillage at draft hood that may trip spill
switch
Flame lifting Leak in vent pipe • Check for leaks in vent connections.
Improper vent conguration • Check vent conguration with manual.
Terminal may be
recirculating ue gases
• Check to see if terminal is on correctly.
• May need to install high wind termination cap.
• Contact dealer.
Glass fogs up Normal Condition: after the appliance warms up the glass will clear.
**Due to additives in gas, glass may get hazy during operation**
Clean as needed
Blue Flames Normal during start up: ames will yellow as the replace heats up.
Flames are burning “dirty”
or sooting
Flame impingement • Check log positioning.
• Increase primary air by opening the venturi shutter.
See also “Burners will not remain lit”.
BV ONLY:
Insufcient air for
combustion
• Air tight house.
• A vacuum in room due to
other air-moving device.
• Supply make up air to the unit.
