Possible Causes
A. Pilot Rectifi cation Failure
B. Blocked Flue/Insuffi cient Draft
C. Shorted Pilot Sense
E. Disconnected Pilot Sense
F. Pre-Existing/False Pilot Flame
Corrective Action
1. Verify that black wire on IPI wire harness is prop-
erly 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 as-
sembly in place, verify that the pilot fl ame is en-
gulfi ng the fl ame 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 orifi ce is in pilot.
4. If #1-4 are correct, replace IPI module.
1. Verify the tefl on pressure tube is connected be-
tween blower impeller housing and vacuum
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 malfunction
is corrected, lock-out system until the vacuum
switch can be replaced.
6. Verify 3/8 in. barrier glass gap is maintained
and not obstructed.
1. Verify that the white sensor lead is properly con-
nected 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 fi rebox or
valve compartment. Replace pilot if damage ex-
ists.
1. Verify that white sensor lead is properly connect-
ed to the S-terminal and the orange ignitor lead
is connected to the I-terminal on the module.
1. Check for pre-existing pilot fl ame. If so, the valve
is defective and should replaced.
