Blower mounting arrangement for forced air furnace

摘要

A forced air furnace has its blower mounted on a blower shelf beneath the heat exchanger, by screws that enter aligned clearance holes in the blower mounting flanges and blower shelf and which engage gripper holes in a bottom lip of the vertical cell panel that serves as the proximal wall of the furnace heat exchanger cell. This provides vertical support for the blower and absorbs stresses from up-and-down motion.
