W415-1347 / A / 03.19.15-62EN25.0 TROUBLESHOOTINGSYMPTOM PROBLEM TEST SOLUTIONPilot will notlight.Makes noisewith nospark at pilotburner.Wiring. - Verify the “S” wire for the sensor and the “I” wire for the ignitorare connected to the terminals on the module and pilot assembly.Loose connection. - Verify no loose connections, electrical shorts in the wiring orground out to any metal object.Module. - Turn the ON/OFF switch to the “OFF” position. Remove theigniter wire “I” from the module. Place the ON/OFF switch to the“ON” position. Hold a grounded wire about 3/16” (4.8mm) awayfrom the “I” terminal on the module. If no spark, the modulemust be replaced. If there is a spark, the module is fine. Inspectpilot assembly for a shorted wire or cracked insulator aroundthe electrode.Igniter Spark gap isincorrect.- Spark gap of the ignitor to the pilot should be .125” (3.2mm)Transformer. - Verify the transformer is installed and plugged into the relaybox. Check voltage of the transformer under load at the spadeconnections on the relay box with the ON/OFF switch in the“ON” position. Acceptable readings of a good transformer arebetween 2.8 and 3.4 volts A.C.A shorted or looseConnection.- Remove and reinstall the wiring harness that plugs into the module.Remove and verify continuity of each wire in wiring harness.Battery backup - Check batteries.Improper switchwiring.- Troubleshoot the system with the simplest ON/OFF switch.Pilot sparksbut will notlight.Gas supply. - Verify that the incoming gas line ball valve is “Open”. Verify that theinlet pressure reading is within acceptable limits, inlet pressuresmust not exceed 7” W.C. (17.4mb) for NG and 13” W.C. (32.4mb)for LP.Out of propane gas. - Fill the tank.Carbonis beingdeposited onglass, logs,rocks, mediaor combustionchambersurfaces.Air shutter hasbecome blocked.- Ensure air shutter opening is free of lint or other obstructions.- Ensure air shutter is properly set.Flame is impingingon the glass,logs, rocks, mediaor combustionchamber.- Check that the glass, logs, rocks or media are correctly positioned.- Open air shutter to increase the primary air.- Check the input rate: check the manifold pressure and orifice sizeas specified by the rating plate.- Check that the door gasketing is not broken or missing and thatthe seal is tight.- Check that both vent liners are free of holes and well sealed at alljoints.- Check that minimum rise per foot has been adhered to for anyhorizontal venting.42.13C! WARNINGALWAYS LIGHT THE PILOT WHETHER FOR THE FIRST TIME OR IF THE GAS SUPPLY HAS RUN OUT,WITH THE GLASS DOOR OPEN OR REMOVED.TURN OFF THE GAS AND ELECTRICAL POWER BEFORE SERVICING THE APPLIANCE.APPLIANCE MAY BE HOT, DO NOT SERVICE UNTIL APPLIANCE HAS COOLED.DO NOT USE ABRASIVE CLEANERS.PILOT TUBEFITTINGINJECTOR
