Intellifi re™ Plus Ignition System - (continued)
Symptom
4. Pilot lights but contin-
ues to spark, and main
burner will not ignite.
(If the pilot continues
to spark after the
pilot fl ame has been lit,
fl ame rectifi cation has
not occurred.)
5. Appliance lights and
runs for a few minutes
and then shuts down
and/or appliance cycles
on and off.
Possible Cause
A. A shorted or loose connection in fl ame
sensing rod.
B. Poor fl ame rectifi cation or contaminated
fl ame sensing rod.
C. Module is not grounded.
D. Damaged pilot assembly or contami-
nated fl ame sensing rod.
A. A shorted or loose connection in fl ame
sensing rod.
B. Poor fl ame rectifi cation or contaminated
fl ame sensing rod.
C. Logs are set up incorrectly.
D. Damaged pilot assembly or contami-
nated fl ame sensing rod.

Corrective Action
Verify all connections to wiring diagram in manual. Verify
connections underneath pilot assembly are tight. Verify
fl ame sense or igniter wires are not grounding out to metal
chassis, pilot burner, pilot enclosure or screen if present, or
any other metal object.
With fi xed glass assembly in place, verify that fl ame is en-
gulfi ng fl ame sensing rod on left side of pilot hood. Flame
sensing rod should glow shortly after ignition. With a multi-
meter, verify that current in series between module and
sense lead is at least 0.14 microamps. Verify correct pilot
orifi ce is installed and gas inlet is set to pressure specifi -
cations. Polish fl ame sensing rod with fi ne steel wool to
remove any contaminants that may have accumulated on
fl ame sensing rod.
Verify module is securely grounded to metal chassis of ap-
pliance. 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 sens-
ing 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.
