A media filter cabinet for a gas furnace is sized to accept a high-efficiency media filter while being easily adaptable to accept a standard size filter. A perforated duct flange on one side of the cabinet permits ease of installation since the flange can be bent at 90 or 180 degrees along the perforations, or removed, depending on the type of duct the cabinet is installed with. The cabinet is adapted to fit a standard filter by using a removable bracket and a wire to retain the standard filter within the cabinet. With the removal of a front door and a back side of the cabinet, the cabinet collapses to diminish its shipping size. In one embodiment, the cabinet is in kit form which is easily assembled.

Media filter cabinet for gas furnace

A gas control assembly for a forced air furnace which includes a support frame having a top surface and two contiguous side walls which define an enclosure. A planar one piece burner assembly which has a plurality of burners and having two opposite side edges with one edge containing indexing means is positioning in a predetermined location within the enclosure of the support frame. A elongated gas manifold having a closed end and an open end which is configured to mate with the burner assembly to provide a source of combustible fuel to each of said burners is connected in fixed engagement to the support frame at its closed end through a hole in one side of said support frame and by a bracket at the open end which is attached to the other side of said support frame. The side walls of the support frame also contain slots which mate with edges of the burner assembly to provide for proper alignment of the burner assembly.

Gas control assembly

A multipoise furnace cabinet includes right and left sides with top and bottom plates connecting upper and lower parts of the right and left sides together. In one embodiment, top and bottom plates include vent cutouts. A side of the top plate has a first partially cut section that aligns with a second partially cut section in a door to the furnace cabinet, wherein the first and second partially cut sections substantially describe a circle, such that when the first and second partially cut sections are removed from the door and the cabinet, a resulting opening permits entry of a flue vent pipe. Front edges of the right and left cabinet sides are flanged, as are the front edges of the top and bottom plates. In another embodiment, the vent cutouts are entirely within the door.

Louver pattern for a gas furnace door

A furnace of the type for supplying circulating heated air to an comfort space, the furnace being contained within a cabinet, having a door allowing access to the interior thereof, which is set in a door frame, wherein the furnace is capable of operating in at least any vertical orientation, an improvement comprising. The bottom end of the door is removably retained against a bottom portion of the door frame, via a hinge, when the furnace is any vertical orientation. At least one latch is located adjacent the top end of the door when the furnace is in any vertical orientation, the latch being constructed to engage a mated door strike; and at least one door strike is located in both a top portion and a bottom portion of the door frame.

Furnace door attachment

In a furnace of the type having a blower shelf with a blower attached to one surface thereof and a heat exchanger unit located proximate a second surface thereof, and the heat exchanger unit being reversibly attachable to the blower shelf, the improvement comprising: a retaining structure unitary with the back panel of the heat exchanger; and a structure which mates with the retaining structure and is unitary with the blower shelf. The retaining structure and mating structure function jointly to retain the back panel of the heat exchanger unit perpendicular to and proximate the blower shelf.

Support for furnace heat exchanger

A cell panel for a gas furnace having a burner box containing combustion burners includes burner target plates formed by an extrusion process from the sheet material forming the cell panel. The burner target plates include a concave side positioned to face the discharge side of a corresponding burner, and a convex side upon which the flared inlet port of a corresponding heat exchanger cell may be securely seated.

Cell panel with extruded burner target plates and process for making same

A furnace for supplying circulated heated air to a comfort zone, the furnace having a condensing heat exchanger and a blower for moving ambient air over the heat exchanger, wherein a transformer for stepping down line voltage (115 VAC) to control voltage (24 VAC) is secured to the inner surface of an enclosed housing within the furnace wherein the inner wall also supports at least one retaining bracket and one fastenable support bracket. A first flange extending from the transformer engages the retaining bracket to rotatably support the transformer. A second flange extending from the transformer engages the fastenable support bracket to secure and further support the transformer supported within the housing. A threaded member secures the fastenable support bracket to the second flange, thereby preventing disengagement.
