S89C Hot Surface Ignition Module
Provide operating control and system shutdown on loss of main
burner flame in direct ignition central heat furnaces and heating
appliances with hot surface igniter.
• S89C,G,J are for systems with a combination igniter- sensor.
• S89C lock out after one try for ignition. S89G,H provide three tries for
ignition before lockout, with 30 sec. min. purge before second and
third tries.
• Compatible with Norton 201 and 271 or equivalent hot surface
igniters.
• Available with leadwires for line voltage connections.
• Modules can be used on either natural or LP gas; they provide 100
percent shutoff of gas on lockout.
• Modules have relay contacts for use with any direct ignition gas
control with max. 2.0 A, 24 Vat rating.
• Modules use rectification principle for flame sensing. -40 F to +175 F
(-40 C to +79 C) temperature rating.
Application: Provide electronic control of direct hot surface ignition
systems used on gas fired furnaces, boilers, and other heating
appliances.

S89E,F Direct Spark Ignition Modules
Provide electronic control of direct spark ignition systems, with
external spark transformers, used on gas-fired furnaces, boilers,
conversion burners and other heating appliances.
• Controls ignition sequence and gas control operation in direct spark
ignition systems.
• Control separate 120 Vac spark generator that provides high voltage
potential for main burner ignition.
• Lockout after one trial for ignition if main burner fails to ignite.
• Reset from thermostat after lockout. Use separate electrodes for
spark ignition and flame sensing.
• Use any 24 Vac combination gas control designed for direct spark
applications and rated at 2.0A or less.
