SF-30 to SF-35 Suburban Furnace Upgrade
Can I replace a SF-30 30000 BTU Suburban furnace with a SF-35 35000 BTU unit?
My SF-30 shook extremely last night and shutdown. Now cool air blows with no heat. Since its 5 years old, I am replacing and will repair this unit as a backup. As I already have 4 interior cabin vents, can I upgrade to a SF-35? The unit is running on a 20 amp fuse and this seems like a better option for our 650 square foot space. The Suburban installation guide specs (except for vent specs) are the same for both units. Thanks. John
