TROUBLE SHOOTING

Problem

Possible Cause

Solution

 

Spark will not light the pilot after

Defective piezo igniter

Check connections to igniter

repeated pressing of spark

 

-If igniter connections are good but

igniter

 

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

-Bleed line.

 

 

while knob is depressed.)

-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

-Check for leaks in vent connections

 

Improper vent configuration

-Check vent configuration with manual

 

Terminal may be recirculating flue

-Check to see if terminal is on correctly

 

gases

-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

 

 

 

the appliance heats up.

 

 

Flames are burning “dirty” or

Flame impingement

-Check log position

Sooting

 

-Increase primary air by opening

 

 

venturi shutters

Flame goes out / comes on

Improper placement of

Move bulb to cooler location

frequently during a short period

thermostatic bulb

 

 

of time
