B. Intellifire Ignition System

 

Symptom

 

Possible Causes

Corrective Actions

1.

The ignitor/module makes

A.

Incorrect wiring.

Verify “S” wire (white) for sensor and “I” wire (orange) for ignitor are

 

noise, but no spark.

 

 

connected to the correct terminals on the module and the pilot assembly.

 

 

 

 

Reversed wires at the module may cause the system to make a sparking

 

 

 

 

noise, but the spark may not be present at pilot hood.

 

 

B.

Loose connections or

Verify there are no loose connections or electrical shorts in wiring from

 

 

 

electrical shorts in the

module to pilot assembly. The rod closest to the pilot hood should be ignitor.

 

 

 

wiring.

Verify connections underneath pilot assembly are tight; also verify the

 

 

 

 

connections are not grounding out to the metal chassis, pilot burner, pilot

 

 

 

 

enclosure, mesh screen if present, or any other metal object.

 

 

C.

Ignitor gap is too large.

Verify gap of ignitor to pilot hood. The gap should be approximately .17 in. or

 

 

 

 

1/8 in.

 

 

D.

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 in. 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 fi ne. Inspect pilot assembly for shorted sparker wire

 

 

 

 

or cracked insulator around electrode.

2.

Pilots won’t light, there is

A.

Transformer installed

Verify that transformer is installed and plugged into module. Check voltage of

 

no noise or spark.

 

incorrectly.

transformer under load at space connection on module with ON/OFF switch

 

 

 

 

in ON position. Acceptable readings of a good transformer are between 3.2

 

 

 

 

and 2.8 volts AC.

 

 

B.

A shorted or loose

Remove and reinstall the wiring harness that plugs into module. Verify there is

C.

Improper wall switch

Verify wall switch is wired correctly.

 

 

 

wiring.

 

 

 

D.

Module not grounded.

Verify black ground wire from module wire harness is grounded to metal

 

 

 

 

chassis of appliance.

 

 

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 in. 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 fi ne. Inspect pilot assembly for shorted sparker wire or

 

 

 

 

cracked insulator around electrode.

3.

correct pilot orifi ce is installed and inlet gas specifi cations are met. Flame

 

 

 

 

 

 

 

 

carries rectifi cation current, not the gas. If fl ame lifts from pilot hood, the

 

 

 

 

circuit is broken. A wrong orifi ce or too high an inlet pressure can cause pilot

 

 

 

 

fl ame to lift. The sensor rod may be contaminated. Clean sensor rod with

 

 

 

 

emery cloth.

 

 

C.

Module is not grounded.

Verify that module is securely grounded to metal chassis of appliance. Verify

 

 

 

 

that the wire harness is fi rmly connected to module.

 

 

D.

Damaged pilot assembly

Verify that ceramic insulator around the sensor rod is not cracked, damaged,

 

 

 

or dirty sensor rod.

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 in. 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 fi ne. Inspect pilot assembly for shorted sparker wire

 

 

 

 

or cracked insulator around electrode.
