The Goodman GKS90453BX Up to 92.1% AFUE Performance Single-Stage, Multi-Speed Upflow Gas Furnace is packed with some of the latest advanced technology featuring that includes a patented aluminized steel made tubular heat exchanger and an energy- efficient hot surface ignition system. The corrosion- resistant tubular heat exchanger with a recuperative coil delivers years of reliable and trouble free service.

With a non- corrosive, painted steel cabinet, this furnace unit can be installed anywhere in your home starting from the garage, conclaves and attic to the crawl space, closet or even the living room.

This gas furnace is meant to serve as a natural gas fed system but it also includes the provision to be transformed for use with propane with the help of a field installed propane conversion kit (LPT- 01A) that’s not included with the furnace but can be purchased separately for only $32. Among its other features, the GKS90453BX family of furnaces allows venting with 2-3 inch PVC without requiring a traditional chimney flue.
