35,000 BTU replacement furnace core module for select Suburban SF-35, SF-35Q, SF-42, SF-42Q, and SF-Q RV furnace models. Slides into the existing compatible cabinet to replace the internal furnace assembly without removing the outer cabinet or ductwork.

About the Suburban 2609A RP-35Q Furnace Core

The Suburban 2609A RP-35Q is a 35,000 BTU replacement furnace core module designed for select Suburban SF-Q series RV furnaces. Instead of replacing the entire furnace assembly, the old core module can be removed and the new core can slide into the existing compatible furnace cabinet.

This design can save time and labor when the existing outer cabinet, ductwork, venting layout, and installation space are still usable. It is commonly used for compatible Suburban SF-35, SF-35Q, SF-42, SF-42Q, and SF-Q 2564A furnace series applications.
