Fenwal 35-72 Series 120 VAC Microprocessor Based Direct Spark Ignition Control

The 35-72 is a 120 VAC direct spark ignition control for controlling a gas valve and igniting LP or natural gas on heating equipment that provides a 120 VAC operating voltage.
The microprocessor circuit design provides precise, repeatable timing sequences for ignition times, purge times (pre- and inter-) along with multiple tries for ignition and flame sensing during pre-purge.

The 35-725201-55 is a 10-Second Single Try for Ignition, with a 5-Second Pre-Purge.
