Two Rod Direct Spark Ignition Control w/ 6 Second Ignition Trial, S8701A1010

The Resideo S8701A1010 is a 24V direct spark ignition control for gas-fired furnaces, boilers, and other heating appliances. It uses separate spark and flame sensing rods and provides one 6-second trial for main burner ignition before safety lockout if flame is not established. The module generates the ignition spark, monitors burner flame, controls the gas valve, and provides LED status indication.

Features

• 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.
