Abstract
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.
Claims16
A termination for use with a furnace, comprising:
- a face plate including an exhaust region and an air supply region, the face plate having a front surface and an opposing back surface;
- an exhaust termination portion coupled to the back surface in the exhaust region, the exhaust termination portion comprising a sleeve capable of engaging a terminal end of an exhaust conduit associated with a furnace;
- an opening extending through the face plate in the exhaust region, the opening aligned with the exhaust termination portion;
- an air supply termination portion coupled to the back surface and extending from the back surface in the air supply region;
- and
- a plurality of stop elements coupled to the back surface in the air supply region, wherein at least one of the stop elements is coupled to the sleeve.
A method of constructing a termination for use with a furnace, comprising:
- providing a face plate including an exhaust region and an air supply region, the face plate having a front surface and an opposing back surface;
- coupling an exhaust termination portion to the back surface in the exhaust region, the exhaust termination portion comprising a sleeve capable of engaging a terminal end of a variety of different size exhaust conduits associated with a furnace;
- providing an opening extending through the face plate in the exhaust region, the opening aligned with the exhaust termination portion;
- positioning a reducing element within the opening to accelerate a flow of exhaust away from the face plate;
- coupling an air supply termination portion to the back surface and extending from the back surface in the air supply region;
- coupling a plurality of stop elements to the back surface in the air supply region, the plurality of stop elements comprising a plurality of step portions operable to engage a variety of different size air supply conduits, wherein at least one of the stop elements is coupled to the sleeve;
- and
- coupling a plurality of freestanding fins to the air supply region, the plurality of freestanding fins at least partially surrounding the air supply termination portion, extending from the back surface toward an air supply conduit associated with the furnace, and perpendicular to the back surface, and operable to reduce the amount of debris able to enter the air supply region.
