Bradford White BW-243-45787-00 Draft Diverter Vent

Product Description

The BRADFORD WHITE BW-243-45787-00 is a draft diverter designed for use in vented water heater installations. It mounts at the flue outlet of the water heater and redirects combustion gases into the vent system while preventing backdrafting from interfering with burner operation. This unit accommodates a 3-inch inlet connection and a 4-inch outlet connection, making it suitable for installations where a transition between flue collar and vent pipe sizes is required. It is typically installed by licensed plumbers or HVAC technicians during water heater service or replacement.

This draft diverter is used in residential atmospheric-vent water heater applications. It sits between the water heater flue collar and the B-vent or single-wall vent connector leading to the chimney or exhaust system. Installations requiring a 3-inch to 4-inch size transition at the draft hood connection point are the primary use case. The part is intended as a direct OEM replacement for Bradford White water heaters originally equipped with this component.
