Problem Cause Solu � on Check
Burner doesn’t turn on IFC ON/OFF circuit is OPEN Ensure ON/OFF circuit is complete Check the ON/OFF switch, con fi rm “-” symbol is pressed down
(check with mul � meter) Check for con � nuity across burner switch
Remote signal not being received Ensure IFC is receiving remote commands (beeping) Re-sync remote
**Remote commands may need to be repeated Weak or dead remote ba � eries
Check reciever antenna is in correct loca � on (see "Fireplace Control Panel")
Check for red blinking light on IFC (see "IFC locked out" below)
No call for heat Ensure heat has been called for Check thermostat se � ng is below set point
Check third party fi replace control
Unresponsive IFC Ensure IFC is working correctly Check circuit breaker
*audible beeps con fi rms IFC is ge � ng power Check for 120VAC at IFC
Check IFC fuse
Check for red blinking light on IFC (see "IFC error" troubleshoo � ng sec � on
Problem with pilot Ensure pilot fl ame is opera � onal See "Pilot fl ame not ligh � ng.." below
Pilot not a � emp � ng to No call for heat Ensure heat has been called for Check thermostat se � ng is below set point
spark Check third party fi replace control
Locked out IFC Reset IFC See "Unresponsive fi replace" below
Spark signal interrup � ed Ensure complete sparker circuit Check electrode rod not shor � ng out on burner pla � orm - adjust rod only if necessary
Check electrode wire not shor � ng out (especially at aluminum pilot line)
Check orange electrode wire has fi rm connec � on at IFC
Check pilot electrode orienta � on to pilot hood - should be no more than 1/4" away
Natural vent Power vent (PV) circuit is OPEN Ensure PV circuit is closed (check with mul � meter) Check the PV switch, con fi rm “-” symbol is pressed down (see "Fireplace Control Panel")
Ensure the IFC PV jumper hasn’t come lose inside the IFC (orange wires)
Power vent Power vent (PV) circuit is CLOSED Ensure PV system is working See "Fireplace unresponsive" below
Pilot fl ame not ligh � ng or Air in pilot gas line Purge pilot gas line May take a few igni � on cycles for gas to self-purge (may need to hard reset IFC a� er cycles)
weak fl ame (has spark at Not enough gas pressure Ensure gas is reaching pilot Check gas inlet supply and pressure (see "Gas Connec � ons")
hood) Check for complete wiring connec � ons at valve (look for faux connec � ons)
Check pilot is set-up for correct fuel-type
Check for pilot fl ame obstruc � ons (typically burner media)
Check for debris in pilot line at pilot head (typically propane units)
Check pilot fl ame adjustment screw on valve
Check for pilot line leak - do you smell gas?
Pilot fl ame not staying lit 7 con � nuous days with no burner opera � on Re-start fi replace using remote This is normal
Problem with fl ame sensor circuit Ensure healthy fl ame re c�fi ca � on Ensure sensor hook is glowing bright red
Check for healthy pilot; ensure sensor hook is fully engulfed in fl ame
Check sensor hook is not touching pilot hood
Check white sensor wire has fi rm connec � on with IFC
Check sensor hook for corrosion, fi lm, or debris
Check pilot for healthly ground (check pilot hood con � nuity)
Exhaust Restrictor Se � ng Ensure correct exhaust restric � on se � ng See "Ven � ng Con fi gura � on"
Flame dropping out Improper fi replace se � ngs Ensure proper fi replace se � ngs Check exhaust restrictor se � ng; see "Ven � ng Con fi gura � on"
(visual fl ame problems) Check ven � ng con fi gura � on is approved
Check for ven � ng obstruc � ons (including at termina � on cap)
Check primary air se � ng; see "Primary Air Adjustment"
Weak or irra � c pilot fl ame Ensure pilot fl ame is healthy Check fl ame sensor circuit; see "Pilot fl ame not staying lit"
Environmental condi � ons (windy) Fireplace adjustment may be necessary Check for approved high-wind termina � on cap
Check for proper fi replace se � ngs (see above)
Adjust exhaust restrictor only if necessary
Environmental condi � ons (extreme cold) Use "Con � nuous Pilot" mode (CPI) This will help the fi replace establish d ra� when freshly turned on
Flame dropping out
(no visual fl ame problems)
Not enough gas supply Ensure proper gas fl ow and pressure Check fuel supply and gas test ports (see "Gas Connec � ons")
Ensure pilot is opera � onal See "Pilot fl ame not staying lit"
Flame li � ing Too much primary air Decrease primary air by closing air shu � er (venturi) See "Adjus � ng Primary Air Se � ng"
Exhaust restrictor se � ng Improper exhaust restrictor se � ng See "Ven � ng Con fi gura � on"; adjust only if necessary
Problem with ven � ng system Ensure ven � ng system is properly set-up Check for approved high-wind termina � on cap
Check ven � ng con fi gura � on is approved
Check for leaks in ven � ng system
Input rate too high Ensure correct gas ori fi ce size and manifold pressure See ra � ng label for details
Trouble establishing d ra� (weather related) Use "Con � nuous Pilot" mode (CPI) This will help the fi replace establish d ra� when freshly turned on
Poor fi rebox seal Ensure complete seal at glass silicone strips Massage silicone strips to fi ll in sliver gaps and voids
Ensure all hand knobs are � ght - ensure upper clamps are in correct slot loca � on
Check for dirt or par � cles s � cking to strips; use denatured alcohol to clean
Side glass may need adjustment (see "Inner Glass Installa � on")
Ensure top and bo � om glass corners are sealed with liquid silicone (not included)
Ensure fi rebox sealed Check for damaged fi berglass perimeter tape
Check for damaged or misalignment of pressure relief door gaskets
Uneven secondary air distribu � on Ensure burner pla � orm is secured Check for missing or stripped screws
Check for warping in burner pla � orm (when installed)
Ensure even air slot height around burner Check for unse � led burner pla � orm (si � ng on a screw, liner clip, or weld build up)
(U70 NG models) Back and forth warping of di ff user mesh This is normal
Incorrect media placement Ensure secondary air slots are cleared Check for piled up burner media covering air slots (vermiculite/glass media)
Flame weaving, bending or
uneven (some is normal)
