Abstract

A water heater includes a combustion assembly having a mounting plate that includes a mounting surface and defines a mounting plate aperture. The combustion assembly includes a burner that has a body that extends through the mounting plate aperture and defines a combustion chamber and a burner flange that extends outward from the body and is coupled to the mounting surface. The combustion assembly further includes a blower assembly. The blower assembly includes a fan, a motor operable to drive rotation of the fan about an axis, and a housing. The housing includes a first housing component that includes a fan-housing portion that at least partially defines a fan-housing region, a tubular portion that defines a hollow, and a housing flange that is coupled to the burner flange. The housing flange defines a plurality of access openings.
