Symptoms
IntelliFire Plus System
Main Closes/ Pilot open, 5 seconds later
pilot sparking with Blower ON. If condition
persists for 60 seconds, 8K-1 locks out with
3 LED alarm.
Pilot and Main shut down and 8K1-PVI
locks out with 4 LED alarm.
Main Closes, 5 seconds later pilot spark-
ing with Blower ON. If condition persists
for 60 seconds, 8K-1 locks out with 3 LED
alarm.
Main Closes, 5 seconds later pilot spark-
ing with Blower ON. If condition persists
for 60 seconds, 8K-1 locks out with 3 LED
alarm.
If given ignition command in both ON and
REMOTE modes, system immediately
locks-out with 3 LED alarm. Does not
spark or attempt to ignite.

taminated fl ame sensing rod.
Possible Causes
Pilot Rectifi cation Failure
Blocked Flue/Insuffi cient Draft
Shorted Pilot Sense
Disconnected Pilot Sense
Pre-Existing/False Pilot Flame
Verify module is securely grounded to metal chassis of appliance.
Verify that wire harness is fi rmly connected to the module.
Verify that ceramic insulator around the fl ame sensing rod is not
cracked, damaged, or loose. Verify connection from fl ame sensing
rod to white sensor wire. Polish fl ame sensing rod with fi ne steel
wool to remove any contaminants that may have accumulated on
fl ame sensing rod. Verify continuity with a multi-meter with ohms set
at lowest range. Replace pilot if any damage is detected.
1. Verify that black wire on IPI wire harness is
properly grounded to the fi replace chassis.
2. Verify that pilot is not being compromised
by draft such that it fails to rectify. With the
glass assembly in place, verify that the pilot
fl ame is engulfi ng the fl ame sensing rod on
the left side of the pilot hood. With a multi-
meter, verify that the current in series be-
tween the module and the sense lead is at
least 0.14 microamps.
3. Verify that line inlet pressure is within range
on rating plate and correct pilot orifi ce is in
pilot.
4. If #1-4 are correct, replace IPI module.
1. Verify the tefl on pressure tube is connected
between blower impeller housing and vacu-
um switch.
2. Verify that wiring within PVI is correct and
that the blower operates during the ignition
command.
3. Verify that the venting is connected and
sealed properly.
4. Verify that the vent termination is not blocked.
5. If #1 thru #4 are complete, connect black and
red wires to bypass vacuum switch. If mal-
function is corrected, lock-out system until
the vacuum switch can be replaced.
1. Verify that the white sensor lead is properly
connected to the S-terminal on the module.
2. Check for soot deposits on the pilot sense
rod, adjacent shielding, or logs. If so, clean af-
fected parts.
3. Verify that the white sense lead from the pi-
lot is not damaged or melted within the fi rebox
or valve compartment. Replace pilot if damage
exists.
Verify that white sensor lead is properly con-
nected to the S-terminal and the orange ignitor
lead is connected to the I-terminal on the mod-
ule
Check for pre-existing pilot fl ame. If so, the
valve is defective and should replaced.
