Integrated Auxiliaries: Features factory-installed 1NO and 1NC contacts for immediate signaling and interlocking

Built to strictly manage LRA (Locked Rotor Amps) during the initial startup phase

System Protection: Acts as a thermal barrier to shield sensitive electronic components from radiant header heat

Fenwal 35-605611-103 Control L99H008 This hot surface igniter isThe Fenwal 35 605611 103 is a direct spark ignition (DSI) control module designed for precise gas burner sequencing in commercial and residential heating applications. Operating on a 24VAC 50 60Hz power supply, this microprocessor based controller manages the gas valve, monitors flame sensing, and executes safety lockdowns. It features a 15 second pre purge (PP) cycle to clear residual gases and a 7 second trial for ignition (TFI) period. The unit is
