CHECKING HONEYWELL S-8600H OR S-8600M 

INTERMITTENT IGNITION CONTROLS 

SPARK AT PILOT BURNER BUT PILOT WILL NOT LIGHT

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. 

Are the wires securely attached to the pilot operator on the gas control 

and to the PV & MV/PV terminals on the ignition module? 

Install a pressure gauge in the pilot tubing line between the 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?

Turn off power supply.

Is ignition cable firmly plugged into pilot assembly and module?  

Is ground wire firmly attached to pilot assembly and GND terminal on 

module?

Are ignition cable and ground wire in good condition (not brittle, burnt, or cracked)?

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?

Is ceramic insulator surrounding the electrode in good 

condition (not cracked or broken)?

Is there excessive draft conditions that may cause pilot 

burner ignition problems?

Correct draft problems in a manner that would ensure 

adequate combustion and ventilation air and proper 

pilot burner performance.

YES

Attach wires firmly.

Replace gas control valve.

Turn on power supply.

Securely connect 

cable and/or ground 

wire.

Replace pilot burner

 and/or ground wire.

Carefully bend down-

wards top of ground

strap to achieve

1/8” spark gap.

Replace pilot burner.

Replace ignition

module.
