{"start":"ifp_start","steps":{"ifp_start":{"title":"IntelliFire Plus Troubleshooting","question":"What problem are you having with this IntelliFire Plus system?","help":"IntelliFire Plus is an intermittent pilot ignition system with wireless control capability, module diagnostics, flame modulation, and optional AUX modules. For basic ignition troubleshooting, wireless controls and battery backup should be eliminated from the system when possible.","professionalHelp":"This guide involves gas, ignition, electrical, and live-voltage diagnosis. If you are not qualified to service gas appliances, stop and request professional help.","showContactForm":true,"stop":false,"options":[{"text":"Pilot will not light, no noise and no spark","next":"ifp_no_noise_no_spark","pathText":"Pilot will not light, no noise and no spark","showContactForm":true},{"text":"Module makes noise, but no spark","next":"ifp_noise_no_spark","pathText":"Module makes noise, but no spark","showContactForm":true},{"text":"Pilot sparks, but pilot will not light","next":"ifp_spark_no_pilot","pathText":"Pilot sparks but pilot will not light","showContactForm":true},{"text":"Pilot lights, but continues sparking","next":"ifp_continues_sparking","pathText":"Pilot lights but continues sparking","showContactForm":true},{"text":"Pilot stays lit, but burner will not light","next":"ifp_burner_no_light","pathText":"Pilot stays lit but burner will not light","showContactForm":true},{"text":"Low flame / low manifold pressure","next":"ifp_low_flame_pressure","pathText":"Low flame or low manifold pressure","showContactForm":true},{"text":"Remote, wall switch, or AUX issue","next":"ifp_remote_accessory_menu","pathText":"Remote, wall switch, or AUX issue","showContactForm":true},{"text":"Diagnostic flash code","next":"ifp_diagnostic_codes","pathText":"Diagnostic flash code","showContactForm":true}]},"ifp_no_noise_no_spark":{"title":"No Noise and No Spark","question":"The pilot will not light, and there is no module noise or spark.","help":"Check that the module selector switch is set correctly. Verify wiring connections, system ground, 120VAC to the junction box, power from the 6VDC transformer, and proper wired wall switch wiring. If the LP/NG selector switch is damaged or not fully engaged, the module may lock out. If power, wiring, ground, and switch position are correct, the control module may be defective.","professionalHelp":"Electrical testing and module diagnosis should be performed by a qualified service technician.","showContactForm":true,"stop":true,"options":[]},"ifp_noise_no_spark":{"title":"Module Makes Noise But No Spark","question":"The module makes sparking noise, but there is no visible spark at the pilot.","help":"Possible causes include loose or improper wiring, poor grounding, disconnected or shorted igniter wire, or incorrect igniter gap. Verify the pilot assembly is grounded. Confirm the igniter wire is properly connected and not shorted to the fireplace chassis. The igniter gap should be approximately 1/8 inch.","professionalHelp":"Ignition testing should be performed by a qualified service technician.","showContactForm":true,"stop":true,"options":[]},"ifp_spark_no_pilot":{"title":"Pilot Sparks But Will Not Light","question":"The pilot is sparking, but the pilot flame does not light.","help":"Verify gas supply is on and all valves in the gas supply line are open and purged of air. Check inlet pressure and pilot gas path. Test voltage to the pilot solenoid during the lighting sequence. The pilot solenoid should read roughly 37 to 47 ohms. If voltage is present but the pilot solenoid does not open, the valve may be defective.","professionalHelp":"Gas pressure and valve testing should be performed only by a qualified service technician.","showContactForm":true,"stop":true,"options":[]},"ifp_continues_sparking":{"title":"Pilot Lights But Continues Sparking","question":"The pilot lights, but the module continues sparking and the main burner will not ignite.","help":"If the pilot lights but continues sparking, flame rectification has not been proven. Check gas supply, sensor rod condition, sensor lead connection, and grounding. Clean the sensor rod if contaminated. Verify the sensor lead is not disconnected or shorted. If the sensor cannot prove flame, the system may time out and enter lockout.","professionalHelp":"Flame-sensing and rectification diagnosis should be performed by a qualified service technician.","showContactForm":true,"stop":true,"options":[]},"ifp_burner_no_light":{"title":"Pilot Stays Lit But Burner Will Not Light","question":"The pilot lights, stops sparking, and remains lit, but the main burner does not light.","help":"If the pilot stops sparking and remains lit, flame rectification has occurred. Check module output to the burner solenoid and verify valve operation. Possible causes include a faulty module or faulty valve/burner solenoid. The burner solenoid should typically read between 56 and 65 ohms with wires disconnected.","professionalHelp":"Voltage and ohm testing should be performed by a qualified service technician.","showContactForm":true,"stop":true,"options":[]},"ifp_low_flame_pressure":{"title":"Low Flame or Low Manifold Pressure","question":"The unit has low outlet/manifold pressure when set to high flame.","help":"Possible causes include stepper motor position loss, gas supply issues, or module/remote programming behavior. If power is interrupted while the stepper motor resets, it may accept the wrong high position. Reset by moving the module selector switch to OFF, then back to REMOTE, then recheck manifold pressure. If using RC300, the remote may override the module HI/LOW switch.","professionalHelp":"Gas pressure testing and stepper motor diagnosis should be performed by a qualified service technician.","showContactForm":true,"stop":true,"options":[]},"ifp_remote_accessory_menu":{"title":"Remote, Wall Switch, or AUX Issue","question":"Which remote, wall switch, or accessory issue are you seeing?","help":"IntelliFire Plus systems may use RC100, RC200, RC300, AUX200, AUX300, optional wired wall switches, and wireless controls. Wireless controls should be eliminated when troubleshooting core ignition problems.","professionalHelp":"Accessory wiring and control diagnosis may require professional service.","showContactForm":true,"stop":false,"options":[{"text":"Remote does not operate unit","next":"ifp_remote_not_working","pathText":"Remote does not operate unit","showContactForm":true},{"text":"Wall switch overrides remote","next":"ifp_wall_switch_override","pathText":"Wall switch overrides remote","showContactForm":true},{"text":"Fan/AUX function does not work","next":"ifp_aux_issue","pathText":"Fan or AUX issue","showContactForm":true},{"text":"Clear module from remote","next":"ifp_clear_remote","pathText":"Clear module from remote","showContactForm":true}]},"ifp_remote_not_working":{"title":"Remote Does Not Operate Unit","question":"The remote control does not operate the fireplace.","help":"The ON/OFF/REMOTE switch on the module must be in the REMOTE position for wireless controls to operate.
