13. TROUBLE SHOOTING
Problem
Possible Cause
Solution
Spark will not arc to the pilot after
repeated pressing of spark ignitor
Defective piezo ignitor
Check connections to ignitor
-If ignitor connections are good but there is no
spark-replace ignitor
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
away from burner 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 rear of 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.
-Check for spillage at draft hood that may trip spill
switch.
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.
insuficiant air for combustion
- Air tight house
- A Vacuum in room due
to other air moving device
EG. Kitchen fan
- supply make up air to the unit.
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
