Ignition Control
APPLICATION
The S8600 family of ignition controls provide ignition sequence, flame monitoring and safety shutoff for intermittent
pilot gas fired heating appliances. These controls provide flame sense and operating sequences suitable for the
application.
Table 1 describes the main features of each available model.

All models provide:
• Natural or LP gas.
• Pilot burner ignition using a high voltage spark.
• Flame rectification circuit to monitor flame presence.
• Monitoring of 24 Vac, pilot, and main gas valve.
• LED indicator for flame presence/strength and
system status/errors.
• Connections for flame reading via standard micro-
ammeter or voltmeter.
