Description
The Weil-McLain 383-500-774, also known as HT Exchrepl Ult105 S1-3, is a replacement part developed for Weil-McLain gas-fired boilers. This serves as an essential part of the hot surface igniter (HSI) assembly. An essential component of the boiler’s secure and effective igniting procedure is the HSI assembly. The HSI ignites the burner’s gas fuel combination by producing a great deal of heat when it is turned on. The 383-500-774 part may serve as the heating element itself or as a crucial part of the HSI assembly. For accurate diagnosis, replacement, and compatibility confirmation that the 383-500-774 is the right part for your particular Weil-McLain boiler type, it’s crucial to speak with a licensed HVAC specialist.
