Solution
Ensure ON/OFF circuit is complete
(check with multimeter)
Ensure IFC is receiving remote commands (beeping)
**Remote commands may need to be repeated
Ensure heat has been called for
Ensure IFC is working correctly
*audible beeps confirms IFC is getting power
Ensure pilot flame is operational
Ensure heat has been called for
Reset IFC
Ensure complete sparker circuit
Ensure PV circuit is closed (check with multimeter)
Ensure PV system is working
Purge pilot gas line
Ensure gas is reaching pilot
Re-start fireplace using remote
Ensure healthy flame rectification
Ensure correct exhaust restriction setting
Ensure proper fireplace settings
Ensure pilot flame is healthy
Fireplace adjustment may be necessary
Use "Continuous Pilot" mode (CPI)
Ensure safety system is functioning correctly
Ensure proper gas flow and pressure
Ensure pilot is operational
Ensure proper sail switch operation
Ensure monitered fan(s) are running at a decent speed
Ensure all fans are seeing at least 100VAC
Ensure proper sail switch operation
Decrease primary air by closing air shutter (venturi)
Improper exhaust restrictor setting
Ensure venting system is properly set-up
Ensure correct gas orifice size and manifold pressure
Use "Continuous Pilot" mode (CPI)
Ensure complete seal at glass silicone strips
Ensure firebox sealed
Ensure burner platform is secured
Ensure even air slot height around burner
(U70 NG models) Back and forth warping of diffuser mesh
Ensure secondary air slots are cleared
Troubleshooting
Check
Check the ON/OFF switch, confirm "-" symbol is pressed down
Check for continuity across burner switch
Check for continuity across timing relay terminal A and B (see "Safety Circuit System")
Re-sync remote
Weak or dead remote batteries
Check reciever antenna is in correct location (see "Fireplace Control Panel")
Check for red blinking light on IFC (see "IFC locked out" below)
Check thermostat setting is below set point
Check third party fireplace control
Check circuit breaker
Check for 120VAC at IFC
Check IFC fuse
Check for red blinking light on IFC (see "IFC error" troubleshooting section
See "Pilot flame not lighting.." below
Check thermostat setting is below set point
Check third party fireplace control
See "Unresponsive fireplace" below
Check electrode rod not shorting out on burner platform - adjust rod only if necessary
Check electrode wire not shorting out (especially at aluminum pilot line)
Check orange electrode wire has firm connection at IFC
Check pilot electrode orientation to pilot hood - should be no more than 1/4" away
Check the PV switch, confirm "-" symbol is pressed down (see "Fireplace Control Panel")
Ensure the IFC PV jumper hasn't come lose inside the IFC (orange wires)
See "Fireplace unresponsive" below
May take a few ignition cycles for gas to self-purge (may need to hard reset IFC after cycles)
Check gas inlet supply and pressure (see "Gas Connections")
Check for complete wiring connections at valve (look for faux connections)
Check pilot is set-up for correct fuel-type
Check for pilot flame obstructions (typically burner media)
Check for debris in pilot line at pilot head (typically propane units)
Check pilot flame adjustment screw on valve
Check for pilot line leak - do you smell gas?
This is normal
Ensure sensor hook is glowing bright red
Check for healthy pilot; ensure sensor hook is fully engulfed in flame
Check sensor hook is not touching pilot hood
Check white sensor wire has firm connection with IFC
Check sensor hook for corrosion, film, or debris
Check pilot for healthly ground (check pilot hood continuity)
See "Venting Configuration"
Check exhaust restrictor setting; see "Venting Configuration"
Check venting configuration is approved
Check for venting obstructions (including at termination cap)
Check primary air setting; see "Primary Air Adjustment"
Check flame sensor circuit; see "Pilot flame not staying lit"
Check for approved high-wind termination cap
Check for proper fireplace settings (see above)
Adjust exhaust restrictor only if necessary
This will help the fireplace establish draft when freshly turned on
Review safety system; see "Safety Circuit System"
Check monitored fan(s) are functioning at a decent speed
Check for complete sail switch operation
Check for continuity across sail switch terminals A and B (see "Safety Circuit System")
Check monitored fan(s) are functioning at a decent speed
Check for complete sail switch operation
Check for continuity across sail switch terminals A and B (see "Safety Circuit System")
Check fuel supply and gas test ports (see "Gas Connections")
See "Pilot flame not staying lit"
Ensure all sail switches are activating when cooling fans turn on (approx 15-20min)
There should be continuity across sail switch terminals when fan operating
Ensure cooling fan is properly mounted on isolators; fan must be level
Check for binding sail switch counterweight
Ensure sail switch body is secured in proper position
Check for blown fan fuse
Check for dust, debris, or pet hair at fan axles
There should be continuity across fan terminals (check when off)
If fan is weak but free of debris then replace
If all fans are weak, check for voltage output across fan rheostat
Check for weak fan (monitered) - See above
Ensure sail paddle is in direct air flow
Ensure cooling fan is properly mounted on isolators; fan must be level
Ensure sail switch body is secured in proper position
See "Adjusting Primary Air Setting"
See "Venting Configuration"; adjust only if necessary
Check for approved high-wind termination cap
Check venting configuration is approved
Check for leaks in venting system
See rating label for details
This will help the fireplace establish draft when freshly turned on
Massage silicone strips to fill in sliver gaps and voids
Ensure all hand knobs are tight - ensure upper clamps are in correct slot location
Check for dirt or particles sticking to strips; use denatured alcohol to clean
Side glass may need adjustment (see "Inner Glass Installation")
Ensure top and bottom glass corners are sealed with liquid silicone (not included)
Check for damaged fiberglass perimeter tape
Check for damaged or misalignment of pressure relief door gaskets
Check for missing or stripped screws
Check for warping in burner platform (when installed)
Check for unsettled burner platform (sitting on a screw, liner clip, or weld build up)
This is normal
Check for piled up burner media covering air slots (vermiculite/glass media)
