Fenwal 35-665576-111 Hot Surface Ignition Control 20SEC Heat Up 120V

The Fenwal 35-665576-111 Hot Surface Ignition Control is used to provide consistent ignition for HVAC systems especially in residential furnaces and hydronic applications. It works at 120V with a heat up time of 20 seconds, the control uses a hot surface igniter that gets hot to safely and efficiently ignite the gas. It adds safety as the supply of gas is held constant by a thermocouple which checks for the presence of a flame. Some benefits include less electrical noise interference, enhanced ignition reliability, and suitability for use with different heating systems.
