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.
