IntelliFire 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 flame has been lit,
flame rectification has
not occurred.)
5. Carbon Deposition
56
Possible Cause
a. A shorted or loose connection in flame
sensing rod.
b. Poor flame rectification or contaminated
flame sensing rod.
c. Module is not grounded.
d. Damaged pilot assembly or contami-
nated flame sensing rod.
e. Module.
a. Log Placement
b. Shutter Setting
c. Gas Type

Corrective Action
Verify all connections to wiring diagram in manual. Verify
connections underneath pilot assembly are tight. Verify con-
nections are not grounding out to metal chassis, pilot burn-
er, pilot enclosure or screen if present, or any other metal
object.
With fixed glass assembly in place, verify that flame is en-
gulfing flame sensing rod on left side of pilot hood. Flame
sensing rod should glow shortly after ignition. Verify cor-
rect pilot orifice is installed and gas inlet is set to pressure
specifications. Polish flame sensing rod with fine steel wool
to remove any contaminants that may have accumulated on
flame sensing rod.
Verify module is securely grounded to metal chassis of ap-
pliance. Verify that wire harness is firmly connected to the
module.
Verify that ceramic insulator around the flame sensing rod
is not cracked, damaged, or loose. Verify connection from
flame sensing rod to white sensor wire. Polish flame sens-
ing rod with fine steel wool to remove any contaminants
that may have accumulated on flame sensing rod. Verify
continuity with a multimeter with ohms set at lowest range.
Replace pilot if any damage is detected.
Turn ON/OFF rocker switch or wall switch to OFF position.
Remove ignitor wire "I" from module. Place ON/OFF rocker
switch or wall switch in ON position. If there is no spark at "I"
terminal module must be replaced. If there is a spark at "I"
terminal, module is fine.
Verify placement and assure flame is not excessively
impinging on log.
Check to assure correct shutter setting for your model and
gas type.
Assure correct fuel matches unit gas model and compo-
nents.
