Page 36 10/08Quadra-Fire • Columbia Bay • 250-5195 Rev. K10 TroubleshootingWith proper installation, operation, and maintenance your gas appliance will provide years of trouble-free service. If you doexperience a problem, this troubleshooting guide will assist a qualified service person in the diagnosis of a problem and thecorrective action to be taken. This troubleshooting guide can only be used by a qualified service technician.Symptom Possible Cause Corrective Action1. After repeated trig-gering of the piezobutton, the spark ignitorwill not light the pilot.a. Defective ignitor. Check the spark at the electrode and pilot. If no spark and electrodewire is properly connected, replace the ignitor.b. Defective pilot ormisaligned electrode(spark at electrode).Using a match, light the pilot. If the pilot lights, turn off the pilot andtrigger the piezo button again. If the pilot lights, an improper gas/airmixture caused the bad lighting and a longer purge period is recom-mended. If the pilot will not light, ensure the gap at the electrode andpilot is one-eighth (1/8) inch to have a strong spark. If the gas is OK,replace the pilot.c. No gas or low gaspressure.Check the remote shut-off valve from the appliance. Usually, there isa valve near the gas main. There can be more that one (1) valve fromthe appliance and the main.d. No LP in tank. Check the LP (propane) tank. You may be out of fuel.2. The pilot will not staylit after carefully follow-ing the lighting instruc-tions.a. Defective thermo-couple.Check that the pilot flame impinges on the thermocouple. Clean and /oradjust the pilot for maximum flame impingement.Ensure that the thermocouple connection at the gas valve is fullyinserted and tight (hand tighten plus 1/4 turn).Disconnect the thermocouple from the valve, place one millivolt leadwire on the tip of the thermocouple and the other meter wire on thethermocouple copper lead. Start the pilot and hold the valve knob in. Ifthe millivolt reading is less than 15mV, replace the thermocouple.b. Defective valve. If the thermocouple is producing more than 15 millivolts, replace faultyvalve.3. The pilot is burning,there is no gas to theburner, the valve knob isin the ON position, andthe ON/OFF switch is inthe ON position.a. ON/OFF switch orwires defective.Check the ON/OFF switch and wires for proper connections. Place thejumper wires across the terminals at the switch. If the burner comes on,replace the defective switch. If the switch is OK, place the jumper wiresacross the switch wires at the gas valve. IF the burner comes on, thewires are faulty or connections are bad.b. Thermopile maynot be generatingsufficient millivoltage.If the pilot flame is not close enough physically to the thermopile, adjustthe pilot flame.Be sure the wire connections from the thermopile at the gas valve ter-minals are tight and that the thermopile is fully inserted into the pilotbracket.Check the thermopile with a millivolt meter. Take the reading at TH-TP& TP terminals of the gas valve. The meter should read 325 millivoltsminimum, while holding the valve knob depressed in the pilot position,with the pilot lit, and the ON/OFF switch in the OFF position. Replacethe faulty thermopile if the reading is below the specified minimum.With the pilot in the ON position, disconnect the thermopile leads fromthe valve. Take a reading at the thermopile leads. The reading shouldbe 325 millivolts minimum. Replace the thermopile if the reading isbelow the minimum.
