Installing a new 90 Plus furnace myself. Needs a platform?
What is "convention"? does it depend on local code? I got a 1998 Ruud 90 plus furnace from a neighbor who is upgrading. I'm replacing a BARD that is about sixty years old and about 50 percent effecient
Does the new furnace rest right on the concrete floor or do I need to put it on some sort of platform to comply with code?
