S8600H TROUBLESHOOTING GUIDE

Note: Before troubleshooting, familarize yourself with the startup and checkout procedure.

Check line voltage power, low voltage transformer, limit

N o

control, thermostat and wiring.

 

 

 

 

 

 

 

 

 

 

Pull ignition lead

 

 

 

 

 

and check spark at

N o

Replace module.

ignition stud.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Spark okay?

 

 

 

 

 

Yes

 

 

 

 

 

 

 

 

 

 

 

Check ignition cable, ground wiring, ceramic insulator and gap, and correct.

Check boot of the ignition cable for signs of melting or buckling. Take protective action to shield cable and boot from excessive temperatures.

Check that all manual gas valves are open. Supply tubing

N o

and pressures are good, and pilot burner orifice is not blocked.

Check electrical connections between module and pilot operator on gas control.

Check for 24 VAC across PV — MV/PV terminals on module. If voltage is okay, replace gas control. If not, replace module.

 

 

•Note: If S8600H goes into lockout, reset system.

N o

• Check continuity of ignition cable and ground wire.

 

 

 

 

• Check that pilot flame covers electrode.

 

 

• Adjust pilot flame current. Minimum signal should read 1.0

 

 

microamp.

 

 

• If problem persists, replace module.

 

 

 

 

• Check for 24 VAC across MV-MV/PV terminals. If no voltage,

N o

replace module.

Check electrical connections between module and gas control. If okay, replace gas control.

 

 

 

Note: If S8600H goes into lockout, reset system.

 

 

 

 

N o

 

• Check continuity of ignition cable and ground wire. Note: If

 

 

 

 

 

 

ground is poor or erratic, shutdowns may occur occasionally

 

 

 

 

 

 

even though operation is normal at the time of checkout.

 

 

 

• If checks are okay, replace module.

 

 

 

 

 

 

 

 

 

 

 

• Check for proper thermostat operation.

 

N o

 

• Remove MV lead at module: If valve closes, recheck

 

 

 

 

 

 

thermostat and wiring. If not, replace gas control.

 

 

 

 

 

 

 

Troubleshooting ends.

Repeat procedure until troublefree operation is obtained.
