Ensure the fireplace is seeing 120VAC
Replace IFC fuse with exact replacement
Reset IFC
PV switch in incorrect posi�on
PV jumper came lose inside IFC
PV switch in incorrect posi�on
Ensure vacuum switch signal reaching IFC
Troubleshooting
Check for logs/rocks covering air slots
Check for excessive burner media (no more than 1 layer thick)
Check for foreign burner media
Visually inspect burner for leaks; replace if necessary - DO NOT TEST WITH OPEN FLAME
This is normal
See "Adjus�ng Primary Air Se�ng"
Poor air shu�er seal on venturi box
See "Ven�ng Configura�on"; adjust only if necessary
See "Adjus�ng Primary Air Se�ng"
Check that the venturi box covers are removed (LP)
See "Ven�ng Configura�on"; adjust only if necessary
Check for approved high-wind termina�on cap
Check ven�ng configura�on is approved
Check ven�ng system for leaks
Check log posi�oning
Check burner media quan�ty (should be one layer deep)
Check for obstructed seconard air slots around burner
Check gas inlet pressure
Check gas manifold pressure (with unit running)
Check gas orifice matches ra�ng label for correct fuel type
This is normal, more so in damper climates
This will reduce the build-up rate; clean as necessary
Ensure heat release areas are at or above minimum spec
Check for foreign objects blocking heat release
Check installa�on sec�on for further details
Check installa�on sec�on for further details
Ensure there're no foreign objects on or above the unit within the chase
Check ven�ng configura�on is approved
Check for ven�ng obstruc�ons
Reduce exhaust restric�on
Check gas inlet pressure
Check gas manifold pressure (with unit running)
Check gas orifice matches ra�ng label for correct fuel type
Visually inspect bulb for signs of damage, confirm con�nuity with mul�meter
Visually inspect bulb for signs of damage, confirm con�nuity with mul�meter
Check for wire chaffing inside light box
Check top light circuit with mul�meter
See "Flame dropping out.."
See "Pilot not ligh�ng.."
Check gas inlet supply and pressure
Press reset bo�on on fireplace switch panel and re-sync remote (tool may be required)
Cut power to IFC (could use circuit breaker) and reconnect
Check circuit breaker
Do any fireplace features work? If so, fireplace has power
Check for 120VAC at the IFC
Check for bare electrical connec�ons
Check for electrical short in top light box
Was there a recent power surge?
See "IFC locked out" for possible causes
Check the posi�on of PV switch - the "-" should be down if opera�ng with natural vent
Ensure the IFC PV jumper hasn't come lose inside the IFC (orange wires)
Check the posi�on of PV switch - the "o" should be down if opera�ng with power vent
Ensure secure wiring interceptor connec�ons at IFC (yellow wires)
Check for con�nuity across vacuum signal while in start-up mode
Check for PV fan opera�on during start-up mode (can you hear it?)
If the sparker is ac�va�ng then PV start-up mode is func�oning, problem lies elsewhere
