F. PVLP-SLP Troubleshooting
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, 5, or 6 LED alarm.
Main Closes, 5 seconds later pilot sparking
with Blower ON. If condition persists for 60
seconds, 8K-1 locks out with 3 LED alarm.
Main Closes, 5 seconds later pilot sparking
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 RE-
MOTE modes, system immediately locks-out
with 3 LED alarm. Does not spark or attempt
to ignite.
Pilot rectifies, burner begins to light, but has a
difficult time fully lighting.

Possible Causes
Pilot Rectification Failure
Blocked Flue/Insufficient Draft
Shorted Pilot Sense
Disconnected Pilot Sense
Pre-Existing/False Pilot Flame
Draft from back of firebox is too strong due to
power vent.
Corrective Action
1. Verify that black wire on IPI wire harness is prop-
erly grounded to the fireplace 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.
1. Verify the teflon pressure tube is connected be-
tween blower impeller housing and vacuum
switch.
2. Verify that wiring within PVLP-SLP is correct and
that the blower operates during the ignition com-
mand.
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.
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.
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
Check for pre-existing pilot flame. If so, the valve is
defective and should replaced.
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.
