Symptoms
Possible Causes
Corrective Action
IntelliFire™ Plus System
Main Closes/ Pilot open, 5 seconds later pilot
sparking with Fan ON. If condition persists for
60 seconds, 8K-1 locks out with 3 LED alarm.
Pilot Rectification Failure
1. Verify that black wire on IPI wire harness is prop-
erly grounded to the appliance chassis.
2. Verify that pilot is not being compromised by draft
such that it fails to rectify. With the glass as-
sembly in place, verify that the pilot flame is en-
gulfing the flame sensing rod on the left side of
the pilot hood. With a multi-meter, verify that the
current in series between 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 orifice is in pilot.
4. If #1-4 are correct, replace IPI module.
No power to the module when fan is on (after
120 sec pre-purge).
Blocked Flue/Insufficient Draft
1. Verify the teflon pressure tube is connected be-
tween fan impeller housing and vacuum switch.
2. Verify that wiring within PVLP-SLP-AU is correct
and that the fan operates.
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 malfunction
is corrected, lock-out system until the vacuum
switch can be replaced.
Main Closes, 5 seconds later pilot sparking with
Fan ON. If condition persists for 60 seconds,
8K-1 locks out with 3 LED alarm.
Shorted Pilot Sense
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 affected
parts.
3. Verify that the white sense lead from the pilot is
not damaged or melted within the firebox or valve
compartment. Replace pilot if damage exists.
Main Closes, 5 seconds later pilot sparking with
Fan ON. If condition persists for 60 seconds,
8K-1 locks out with 3 LED alarm.
Disconnected Pilot Sense
Verify that white sensor lead is properly connected
to the S-terminal and the orange ignitor lead is con-
nected to the I-terminal on the module
If given ignition command in both ON and RE-
MOTE modes, system immediately locks-out
with 3 LED alarm. Does not spark or attempt
to ignite.
Pre-Existing/False Pilot Flame
Check for pre-existing pilot flame. If so, the valve is
defective and should be replaced.
Pilot rectifies, burner begins to light, but has a
difficult time fully lighting.
Draft from back of firebox is too strong due to
power vent.
Make sure air baffle is properly adjusted. If it is ad-
justed properly, place ember material along the back
side of the ports that are experiencing the difficult
lighting. This will block a portion of the strong draft.
