Series 35-70 Microprocessor Based Direct Spark Ignition Control, 120V (10 Second TFI)

The 35-70 is a 120 VAC direct spark ignition control for controlling a gas valve and igniting LP or natural gas fired equipment and gas burner applications that provide a 120 VAC operating signal.

The microprocessor circuit design provides precise, repeatable timing sequences for ignition times and purge times (pre- and inter-) as well as multiple tries for ignition, one hour automatic reset and flame sensing during pre-purge. The on-board diagnostics with LED output provide assistance with trouble-shooting to ensure safe and efficient burner operation.
