Intellifire Plus™ Ignition System - (continued)
Symptom
4. Pilot lights but
continues 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. 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 flame
sensing rod.
B. Poor flame rectification or contaminated
flame sensing rod.
C. Module is not grounded.
D. Damaged pilot assembly or
contaminated flame sensing rod.
A. A shorted or loose connection in flame
sensing rod.
B. Poor flame rectification or contaminated
flame sensing rod.
C. Logs are set up incorrectly.
D. Damaged pilot assembly or
contaminated flame sensing rod.
Corrective Action
Verify all connections to wiring diagram in manual. Verify
connections underneath pilot assembly are tight. Verify
flame 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 fixed glass assembly in place, verify that flame is
engulfing flame 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 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
appliance. 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
sensing rod with fine steel wool to remove any contaminants
that may have accumulated on flame sensing rod. Verify
continuity with a multi-meter with ohms set at lowest range.
Replace pilot if any damage is detected.
