G. IFT-Controls and PVI-SLP Power Vent Troubleshooting
Symptoms
System will not respond to 'ON' command.
IFT-ECM in lockout with 5 RED:1 GREEN LED
Error Code. RC400 shows 'Call Dealer - Power
Vent Error' Message
System responds to 'ON' command. After
PVI-SLP completes 60 second pre-purge, IFT
system fails to rectify proven pilot flame. IFT-
ECM in lockout with 3 RED:1 GREEN LED.

Hearth & Home Technologies • Power Vent Low Profile (PVLP-SLP) Instructions • 4052-900 Rev. M• 09/17
Possible Causes
1. Power Vent Motor Failure
2. Power Vent Over Heating
3. Power Vent Pressure Switch Open
4. Blocked Flue
5. Insufficient Draft
6. IFT-ECM selector switch in 'ON' Mode
7. IFT-ECM not paired to remote and
Power Vent,
Pilot Rectification Failure resulting from:
1. Soot or embers contaminating pilot and
burner
2. Shorted/melted pilot white 'S' sensor wire
3. Disconnected pilot white 'S' sensor wire
4. Excessive draft turbulence acting on the
pilot flame
5. Oxidation or resistance on the IPI pilot
flame sense electrode
6. Supply gas pressure out of specification
Excessive draft.

Corrective Action
1. Verify that the wiring within the Power Vent is
correct. Verify that the PVI-SLP Cord assembly
is correctly connected to the IFT switch wires,
and the AUX port on the IFT-ACM.
2. Verify that blower operates during 'ON' com-
mand.
3. Verify that the PVI-SLP is correctly installed
such that it is properly vented and will not over-
heat.
4. Verify that venting is connected and sealed
properly. Verify termination is not blocked.
5. Verify the Teflon tube between the blower and
pressure switch is securely connected.
6. Verify that the 'ON' command is provided with
IFT-ECM in 'REMOTE' mode with approved re-
mote control.
7. Re-pair the ECM to the Power Vent.
1.
Verify that the IPI Pilot is clean. If necessary,
remove any soot or ember deposits, and clean/
polish flame sensor electrode with fine steel
wool. If sooting is present, determine possible
causes to correct issue.
2. Verify that the IPI pilot white 'S' wire is securely
connected to the IFT-ECM, and is not melted/
pinched/shorted along its length. Replace pilot
is damage exists.
3. Verify that the gas supply working inlet pressure
is within the specification range.
4. Verify that the black wire on the IFT wiring har-
ness is securely attached to the chassis ground.
5. Verify that the pilot flame is igniting easily, and
the pilot flame is not compromised by excessive
draft. With glass assembly fully installed, verify
that the pilot flame is stable and fully engulfing
the flame sensor electrode.
6. Verify that the pilot sensor/wire resistance is < 1
ohm. If > 1 ohm, and flame rectification is occur-
ring slowly, replace the pilot.
1. Verify that the glass is properly installed and all
latches are engaged.
2. Place ember material along the back side of the
affected burner ports – that can reduce draft af-
fect and promote ignition.
