A. Intellifire Ignition System

Symptom

Possible Cause

Corrective Action

 

 

 

1. Pilot won’t light.

a. Incorrect wiring.

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

The ignitor/module

 

are connected to correct terminals on module and pilot assembly.

module to pilot assembly. Verify connections underneath pilot as-

 

 

sembly are tight; also verify connections are not grounding out to

 

 

metal chassis, pilot burner, pilot enclosure, mesh screen if present,

 

 

or any other metal object.

 

 

 

 

c. Ignitor gap is too large.

Verify gap of igniter to right side of pilot hood. The gap should be

 

 

approximately .17 inch or 1/8 in. (3 mm).

 

 

 

 

d. Faulty module.

Turn ON/OFF rocker switch or wall switch to OFF position. Remove

 

 

ignitor wire “I” from module. Place a grounded wire about 3/16 in. (5

 

 

mm) away from “I” terminal on 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. Inspect pilot assembly for shorted sparker wire or cracked

 

 

insulator around electrode. Replace pilot if necessary.

 

 

 

2. Pilot won’t light,

a. No power or transformer installed

Verify that transformer is installed and plugged into module. Check

Verify there is a tight fit. Verify pilot assembly wiring to module. Re-

 

 

move and verify continuity of each wire in wiring harness. Replace

 

 

any damaged components.

 

 

 

 

c. Improper wall switch wiring.

Verify that 110/VAC power is “ON” to junction box.

 

 

 

 

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. Re-

 

 

move 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. Inspect pilot assembly for shorted sparker wire or cracked

 

 

insulator around electrode.

 

 

 

3. Pilot sparks, but

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 incorrect.

Verify that spark gap from ignitor to pilot hood is .17 in. or 1/8 in (3 mm).

 

 

 

 

c. Module is not grounded.

Verify module is securely grounded to metal chassis of appliance.

 

 

 

 

d. Module voltage output / Valve/Pilot

Verify battery voltage is at least 2.7 volts. Replace batteries if volt-
