Intellifire Ignition System - (continued)
Symptom Possible Causes Corrective Actions
c. Module is not
grounded.
Verify that module is securely grounded to metal chassis of appliance. Verify
that wire harness is firmly connected to module.
d. Damaged pilot
assembly or dirty
sensor rod.
Verify that ceramic insulator around the sensor rod is not cracked, damaged,
or loose. Verify connection from sensor rod to white sensor wire. Clean
sensor rod with emery cloth to remove any contaminants that may have
accumulated on sensor rod. Verify continuity with a multimeter with ohms set
at lowest range.
e. Faulty module. 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. Hold ground wire about 3/16 inch away from "I" terminal on module.
If there is no spark at "I" terminal module must be replaced. If there is a
spark at "I" terminal, module is fine. Inspect pilot assembly for shorted
sparker wire or cracked insulator around electrode.
4. Pilot sparks, but
Pilot will not light.
a. Correct gas
supply.
Verify that incoming gas line ball valve is "open". Verify that inlet pressure
reading is within acceptable limits, inlet pressure must not exceed 14 in.
W.C.
b. Ignitor gap is
too large.
Verify that spark gap from ignitor to pilot hood is .17 in. or 1/8 in.
c. Module is not
grounded.
Verify module is securely grounded to metal chassis of appliance.
