CHECKING HONEYWELL S8600H OR
INTERMITTENT IGNITION CONTROLS
SPARK AT PILOT BURNER BUT PILOT WILL NOT LIGHT
Attach wires firmly.
Replace gas valve.
Turn on power supply.
Securely connect
cable and/or ground
wire.
Replace pilot burner and/or ground wire.
NO
Ensure all manual shutoff valves are fully open; all filters are clean; all gas connections are gas tight; pilot tubing is not damaged, obstructed or kinked; and pilot orifice is unclogged. Check for air in gas line, purge (bleed) line if necessary.

|
|
| YES | |||

| Install a pressure gauge in the pilot tubing line between the | |||||
NO | gas control and the pilot burner assembly. Ensure that the pilot | |||||
| adjustment screw (under cap) is adjusted to a position that will | |||||
| permit gas to flow. | |||||
| Is pilot gas flowing during ignition attempt? | |||||

| terminal on module? |
| ||||
|
|
|
|
| ||
|
|
| YES | |||
Are ignition cable and ground wire in good condition (not brittle, burnt, or cracked)?
Carefully bend down- wards top of ground strap to achieve 1/8” spark gap.
NO
YES
Ensure ground strap is the closest metal to the igniter/sensor rod (electrode) to prevent the spark from shorting out to other metal parts (pilot screen, pilot shield, etc.).
Ignition cable must not touch metal surfaces or current carrying wires.
Is there a 1/8” gap between ground strap and electrode?
Replace pilot burner.
Replace ignition
module.
|
| YES | |
NO |
|
| |
Is ceramic insulator surrounding the electrode in good | |||
| |||
| condition (not cracked or broken)? | ||
|
|
| |
|
| YES | |
NO |
|
| |
Is there excessive draft conditions that may cause pilot | |||
| burner ignition problems? | ||
|
| YES | |
|
|
| |
Correct draft problems in a manner that would ensure adequate combustion and ventilation air and proper pilot burner performance.
