Abstract
A furnace blower housing that can be flush mounted to a furnace and includes an integrally formed round exhaust outlet. The blower housing is formed from two separate housing members joined to each other. The blower housing includes an impeller cavity that encompasses a rotating impeller that directs the exhaust gases out of a rectangular outlet. An integrally formed transition section extends from the rectangular outlet to a circular exhaust outlet. The transition section is formed by a bottom half integrally formed with the first housing member and a top half integrally formed with the top housing member. The exhaust outlet is offset from the back plate of the blower housing such that the blower housing can be flush mounted to a furnace.
