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.

First claim

What is claimed is:

1. 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;
a removably positioned reducing element positioned in the opening and in a portion of the sleeve;
an air supply termination portion coupled to the back surface and extending from the back surface in the air supply region, wherein the air supply termination portion comprises a plurality of stop elements coupled to the back surface in the air supply region; and
a plurality of freestanding fins in the air supply region.

2. The termination of claim 1 wherein the sleeve comprises a plurality of portions operable to engage a variety of different size exhaust conduits, and wherein the plurality of step portions substantially coincides with the plurality of portions.

3. The termination of claim 1 , wherein at least one of the stop elements is coupled to the sleeve.

4. The termination of claim 1 further comprising a first plurality of mounting posts coupled to one or more of the plurality of stop elements and a second plurality of mounting posts coupled to the sleeve.

5. The termination of claim 1 , wherein at least one of the plurality of freestanding fins is positioned at an angle with respect to a radius from a center of an air supply conduit.

6. The termination of claim 1 , wherein the plurality of freestanding fins extends in a direction parallel with airflow in an air supply conduit associated with the furnace.

7. The termination of claim 1 , wherein the plurality of freestanding fins partially surround the entire back surface.

8. The termination of claim 1 , wherein the sleeve comprises a first portion and a second portion extending perpendicularly from the back surface, wherein the first portion is nearest to the face plate and has a smaller diameter than the second portion.
