Engineered to withstand the thermal stress common in commercial and residential heating applications

ensuring perfect alignment within the bearing assemblies to prevent premature wear or vibration-induced failure

By integrating this hot surface ignition conversion

With a standard 1/2-inch NPT threaded hub and a liquid-tight cord connector

this cast iron sheave minimizes vibration and reduces mechanical drive losses by securing a tight fit on the 1" motor or fan shaft

Fenwal 35-605606-115 Control Els PW 17895 Engineered to withstand the thermalThe Fenwal 35 605606 115 is a 24VAC microprocessor based Direct Spark Ignition (DSI) control designed for precise burner supervision in gas fired HVACR equipment. This unit is engineered for heavy duty applications, providing a 15 second pre purge, a 10 second trial for ignition (TFI), and three ignition attempts before safety lockout. As a veteran grade ignition control module, it features Detect A Flame technology for sensitive flame rectification
