Abstract
A blower for a water heater having a flue defining a flue axis. The blower includes a housing at least partially defining a first chamber and a second chamber and having an inlet opening into the first chamber and an outlet communicating between the second chamber and atmosphere, the inlet being alignable with the flue, a ramp extending through the second chamber and having a surface, the surface being oriented at an acute angle with respect to the flue axis, and an impeller positioned in the second chamber and being operable to draw exhaust from the flue into the first chamber through the inlet and being operable to direct the exhaust through the second chamber and across the surface of the ramp, the surface of the ramp directing the exhaust through the outlet in a direction substantially parallel to the flue axis.
