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 extending from 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;
an opening extending through the face plate in the exhaust region, the opening aligned with the exhaust termination portion;
a reducing element removably positioned within the opening to accelerate a flow of exhaust away from the face plate;
an air supply termination portion extending from the back surface in the air supply region;
a 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
a 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.

2. The termination as recited in claim 1 wherein the plurality of freestanding fins are independent of the plurality of stop elements and extend further than a first step portion of the plurality of step portions.

3. The termination as recited in 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.

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

5. The termination as recited in claim 1 wherein the plurality of freestanding fins extend in a direction parallel with airflow in the air supply conduit associated with the furnace.

6. The termination as recited in claim 1 , wherein the plurality of freestanding fins partially surround the entire back surface.

7. A heating system, comprising:
a furnace, including;
a cabinet having an exhaust outlet and a combustion air inlet;
a blower located within the cabinet and positioned to force air through the cabinet;
a gas control valve located proximate the cabinet;
burners located within the cabinet and coupled to the gas control valve; and
a heat exchanger positioned within the cabinet to receive a gas flame from the burners; and

a termination configured to couple to the furnace via an exhaust conduit coupled to the exhaust outlet, the termination including:
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 extending from 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;
an opening extending through the face plate in the exhaust region, the opening aligned with the exhaust termination portion;
a reducing element removably positioned within the opening to accelerate a flow of exhaust away from the face plate;
an air supply termination portion extending from the back surface in the air supply region;

a 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
a 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.

8. The termination as recited in claim 1 , wherein the reducing element is positionable within the opening from the front surface of the face plate.

9. The termination as recited in claim 1 , wherein the reducing element is positionable within the opening from the back surface of the face plate.

10. The heating system as recited in claim 7 , wherein the reducing element is positionable within the opening from the front surface of the face plate.

11. The heating system as recited in claim 7 , wherein the reducing element is positionable within the opening from the back surface of the face plate.
