Provide electronic control of direct spark ignition systems used on gas fire furnaces, boilers, and other heating appliances.

• Control ignition sequence and gas control operation.
• Generate 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 modules (except S87C) with any combination gas control designed for direct spark applications and rated 2.0A or less.
