Water heater assembly having a condensate trap

A condensate trap, comprising:

• a float;
• and
• a housing comprising:
• an upper housing portion that defines an upper chamber within which the float is disposed;
• an inlet through which exhaust gases and liquid condensate flow into the upper chamber;
• an exhaust outlet through which exhaust gases flow out of the upper chamber;
• a lower housing portion that defines a lower chamber positioned beneath the upper chamber;
• a divider that extends between the upper and lower chambers and includes an upper face that defines the upper chamber cooperatively with the upper housing portion, and a lower face opposite the upper face that defines the lower chamber cooperatively with the lower housing portion;
• a port that extends through the divider from the upper chamber to the lower chamber;
• a condensate outlet through which liquid condensate flows out of the lower chamber;
• and
• a collar that projects downward from the lower face of the divider to a lower lip of the collar that is distal from the lower face, such that the collar extends about the port, wherein the lower lip of the collar is positioned below the condensate outlet, such that liquid condensate accumulated within the lower chamber to a level that is above the lower lip and below the condensate outlet cooperates with the collar to form a trap that isolates the port from the condensate outlet.

• a port that extends through the divider from the upper chamber to the lower chamber;
• and
• a condensate outlet through which liquid condensate flows out of the lower chamber;
• and
• a float disposed within the upper chamber and being pivotably coupled to the housing, such that the float is operable to pivot about a pivot axis within the upper chamber between a closed condition and an open condition, the float comprising:
• a float valve that, in the closed condition of the float, is configured to abut a port wall that extends from the upper face of the divider to the lower face of the divider to form the port, such that the float valve restricts the flow of exhaust gases through the port from the upper chamber to the lower chamber;
• and
• a float body that includes a lower surface from which the float valve extends, an upper surface, and a side surface that extends between the upper and lower surfaces, wherein, in the closed condition of the float, a first vertical line that intersects the pivot axis and extends within a plane that is perpendicular to the pivot axis extends a first distance from the lower surface to the upper surface of the float body, a second vertical line that extends within the plane between the float valve and the pivot axis extends a second distance from the lower surface to the upper surface of the float body, and a third vertical line that extends within the plane, such that the float valve is positioned between the third vertical line and the pivot axis, extends a third distance from the lower surface to the upper surface of the float body, and wherein the first distance is less than the second distance, and the second distance is less than the third distance.
