Direct Spark Ignition Control Module

APPLICATION

The S89E,F Direct Spark Ignition Control Modules control the
ignition sequence and gas control operation in direct spark
systems used primarily on gas-fired atmospheric and power
burners in residential furnaces and heating appliances.

FEATURES

• Requires separate 120 Vac spark generator.
• S89E has 10-second maximum delay for safe start check
before ignition.
• S89F has 38-second maximum delay for safe start check
plus valve on delay before ignition.
• Available with 4 or 11 second (nominal) lockout timing.
• 100 percent shutoff for use with all heating gases.
• Ambient temperature rating is -40°F to +175°F (-40°C to
+80°C).
• Separate electrodes for spark ignition and flame sensing.
• Uses Resideo or any other 2A or less dual valve
combination gas control designed for Direct Spark Ignition
(DSI) applications.
• Locks out system after trial for ignition if main burner fails
to ignite.
• Flame rectification principle used to monitor flame; false
flame signals resulting from short to ground results in
safety shutdown.
