IGNITION CONTROL

Each heater is equipped with an ignition control. The solid state ignition control, ignites the burner by utilizing a spark igniter. The spark igniter shuts off during the heating cycle and the burner flame is sensed through a remote flame sensor.

The ignition control will try to ignite the burner three times before lockout. The control waits 15 minutes before trying again to ignite the burner. This is a continuous cycle.

This is a 24 VAC ignition control. The microprocessor circuit design provides precise, repeatable timing and operating sequences. The on-board diagnostics with LED output make troubleshooting easy and ensures safe and efficient operation.
