PILOT TROUBLESHOOTING

A.Pilot won’t light

1.Make sure valve setting is in the pilot position.

2.Check for spark at igniter.

a.If no spark:

1.Check the wiring between the piezo and the igniter. Wire may be looped and be sparking to stove body. If so, move wiring. Check tightness of piezo mounting nut. If this does not remedy the problem you may have a faulty piezo or cracked ceramic on the electrode.

2.Call your Quadra-Fire dealer.

b.If there is a spark:

1.Try to light the pilot with a match (use caution when doing this.) First open door and smell for gas, then toss lit match below pilot. Watch for blue flame. The flame should either light or flutter.

a.If the flame flutters but does not light the pilot, there is probably air in the line. Hold match or lighter flame to pilot hood, then bleed the line until gas comes through.

b.If the match flame does not flutter, make sure the gas is turned on and be sure you are pushing the knob in all the way. If this still doesn’t help, you may be dealing with a bad valve, a blocked pilot orifice, or a kinked pilot line.

3.Call your dealer or authorized service person.

B.Pilot goes out when knob is released

1.Wait five minutes and try again. If the pilot still goes out, try again and hold the knob in longer.

2.If the problem persists, look to see that the pilot flame is contacting thermopile and thermocouple, see picture on following page. If flame is not contacting thermopile and thermocouple, pilot adjustment screw can be turned counter clockwise to increase pilot flame. If flames do not increase, chances are the inlet pressure is low. The inlet pressure cannot be checked accurately unless burner is lit. Turn off gas supply valve and disconnect from appliance. Quickly turn on and listen for ample gas supply. If volume is good, call your dealer or authorized service person.

C.Pilot lights but burner won’t ignite

1.Make sure the knob is turned to the “on” position.

2.Turn the thermostat up. Make sure burner switch is in the OFF position.

3.If there is no thermostat, flip the manual switch on the control panel of the stove. If the burner does not light, short out the thermostat screws on the face of valve marked TH and TPTH. If the burner lights, you may have a problem in the wiring of the stove, and it should be checked.

4.Check the thermostat and thermopile connections at the valve, and tighten or reconnect if needed. Check thermopile connections for grounding. Check that thermopile lead nut is snug. (Do not over tighten.)

5.If the burner still will not ignite, you may have a bad valve; call your dealer or authorized service person.

Check the pilot and burner flames periodically. When properly adjusted, the pilot flame should look like the illustration on the following page. Call your dealer or authorized service person to have the pilot properly adjusted.
