A header box, a furnace and a blocked condensation protection system are disclosed herein. In one embodiment, the header box includes: (1) a first channel having a first channel supply port positioned to be in fluid communication with an inlet of a combustion air blower and a first pressure port couplable to a first input of a pressure sensing device, the combustion air blower and the pressure sensing device associated with the cold end header box and (2) a second channel having a second channel supply port positioned to be in fluid communication with the inlet of the combustion air blower, a second pressure port couplable to a second input of the pressure sensing device and a pressure reference inlet, the second channel in fluid communication with the first channel and configured to have about a same pressure as the first channel when the pressure reference inlet is blocked.

One aspect of the disclosure provides a termination for use with a furnace. The termination, in one embodiment, includes a face plate including an exhaust region and an air supply region, the face plate having a front surface and an opposing back surface. The termination, in this embodiment, further includes an exhaust termination portion extending from the back surface in the exhaust region, the exhaust termination portion capable of engaging a terminal end of a variety of different size exhaust conduits associated with a furnace. The termination, in this embodiment, further includes an opening extending through the face plate in the exhaust region, the opening aligned with the exhaust termination portion.

One aspect of this disclosure provides a heat exchanger that comprises a first panel half coupled to a corresponding second panel half that form a passageway having at least a first chamber adjacent an inlet end of the passageway and a second chamber and overlapping interference patterns formed in each of the first and second panel halves that extend along at least a portion of the length of the passageway and located between at least the first and second chambers.

A condensation trap comprising an inlet chamber, a vent chamber and an outlet chamber. The inlet chamber is configured to receive condensate fluid through an external opening therein. The vent chamber is in fluid communication with the inlet chamber via a first passageway that includes an internal opening of the inlet chamber. The internal opening is located substantially at an opposite end of the vent chamber as the external opening. The outlet chamber is in fluid communication with the vent chamber via a second passageway that includes an internal opening in a sidewall of the vent chamber and an interior opening in an end of the outlet chamber. The outlet chamber is configured to transmit the condensate fluid through an exterior opening located at an opposite end of the outlet chamber. A vent volume portion is greater than a total volume of an internal space of the inlet chamber.

The invention relates to a manifold (10) for a heat exchanger (1), comprising a cover (31), an intermediary plate (41), and a collector plate (51), said manifold (10) being intended to collect and distribute a fluid. According to the invention, the intermediary plate (41) defines a first fluid chamber (11) with the cover (31) and a second fluid chamber (12) with the collector plate (51), said second chamber being independent of the first (11). The invention also relates to a heat exchanger (1) comprising such a manifold (10) and to a method for producing such a manifold (10).

One aspect of the disclosure provides a termination for use with a furnace. The termination, in one embodiment, includes a face plate including an exhaust region and an air supply region, the face plate having a front surface and an opposing back surface. The termination, in this embodiment, further includes an exhaust termination portion extending from the back surface in the exhaust region, the exhaust termination portion capable of engaging a terminal end of a variety of different size exhaust conduits associated with a furnace. The termination, in this embodiment, further includes an opening extending through the face plate in the exhaust region, the opening aligned with the exhaust termination portion.

An improved heat exchanger having a pair of headers and at least one tube extending between and fluidly connecting the headers. A tubular structure for and defining in part each of the headers. The tubular structure being defined by a pair of body elements and having opposed longitudinal joints defined by overlapping portions of the body elements. One of the body elements overlaps the other of the body elements to define one of the joints and is overlapped by the other of the body elements to define the other of the joints.
