A fan coil unit is provided including a cabinet formed from a plurality of panels. A fan assembly is configured to circulate air through the cabinet. A heat exchanger assembly is positioned within the cabinet. The heat exchanger assembly includes at least one heat exchanger coil arranged in a heat transfer relationship with the air circulating through the cabinet. An inner surface of at least one of the plurality of panels is partially lined with an elastomeric foam insulation so that the air circulating through the cabinet does not contact the portion of the at least one panel lined with the elastomeric foam insulation.

A mounting structure () for receiving a sensor () having a sensing portion () and a base portion () includes a substantially flat sheet of material () having a first surface (), a second surface () opposite the first surface (), and an aperture (). The aperture () is configured such that the sensing portion () of the sensor () is passable through the aperture (), and the base portion () is not passable through the aperture (), but instead rests on the first surface (). The mounting structure () also includes a pair of tabs () that extend in a downward direction away from the second surface () of the sheet of material () and are configured to immobilize the sensor () within the aperture ().

A clamshell heat exchanger panel has a pocket formed in an edge of a land portion of the panel so that a fastener can be inserted into the pocket, with its axis in the plane of the heat exchanger panel. This allows attachments to be made directly to the exchanger panel without affecting the integrity of the gas-carrying conduit portion of the panel. The pocket is made by forming mirror image indentions in the land portions of the two sides of a sheet metal workpiece such that, when the two sides are folded together, the indentions cooperate to form the pocket. Openings can also be formed through the land portions of the two sides so that, upon a folding together, the openings define an opening into the pocket.

A draft safeguard apparatus for use in a multi-poised furnace having an inducer housing for receiving flue gases from a heat exchanger. The furnace flue pipe is attached to the inducer housing by an elbow that is rotatably connected to the inducer housing. An elongated sensor housing is mounted upon the elbow. The housing provides a flow channel so that the inlet section of the elbow communicates with the surrounding ambient. A limit switch is mounted in the housing to sense the temperature in the flow passing through the housing. When the furnace is operating normally, ambient air is drawn into the vent system through the sensor housing. If the vent system becomes restricted, the flow through the housing is reversed and the limit switch is opened when the reverse flow temperature exceeds a given limit. A baffle that includes a flat, rectangular-shaped top plate is mounted inside the elbow to form a chamber over the entrance to the sensor housing which directs the flue gas flow over the entrance when the vent system is unblocked and directs the flue gas flow into the gas sensor housing in the event that the vent system becomes blocked.

In a furnace having a plurality of parallel heat exchanger panels over which circulation air is caused to flow, and which has a tendency for hot spots to occur at particular locations on its outboard heat exchanger panels, a diverter vane is placed on the outer side of each of the outboard heat exchanger panels to divert a portion of the circulation air to the hotspot locations for cooling them to acceptable temperatures. In one form, the diverter vane is integrally formed with, and extends normally inwardly from a side baffle that extends upwardly alongside the outboard heat exchanger panel. The diverter vane is obliquely disposed with respect to the side baffle, with its lower end located near a midpoint of the heat exchanger panel and its upper end located near the hotspot location. When used with a multipass heat exchanger panel, the hotspot location is between the end of the first return bend and the commencement of the second pass, and the diverter vane is thus positioned with its top end near that location. Where a blower shelf baffle is employed, the diverter vane lower end is positioned near that location.

A mount for a disc-type switch having a body that is centered upon a mounting flange. The mount includes a substrate having a central opening that permits the switch and mounting flange to be inserted into the opening. The substrate has a depression formed therein on one side of the opening that complements the shape of the flange and has a size that will accept about one half of the flange therein when the switch is passed into the opening and the flange rotated. At this time the other half of the flange is brought into contact with the top surface of the substrate. A threaded fastener secures the flange to the substrate so that at least one half of the flange is supported by the substrate to resist the downwardly directed forces acting upon the switch and the other half of the flange is supported in the housing to resist upwardly directed forces upon the switch.

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.

Door panel for a residential furnace

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.

A one piece cell panel for a forced air furnace which is designed for ease of removal without the necessity of having to dismantle the furnace cabinet. The panel includes a substantially vertically disposed upper section which contains a plurality of cell inlets and cell outlets and an integral lower horizontal shelf which is disposed at a predetermined acute angle downward below the horizontal. The cell panel has a substantially rectangular front profile and an &ldquo;L&rdquo; shaped side profile.

A compact gas combustion furnace includes a substantially rectangular casing having an interior defined by a plurality of compartments. A draft inducer is mounted above the heat exchanger compartment to allow a multipass heat exchanger to be used while allowing the furnace to be fitted within a mobile home closet. A transition box couples the horizontally disposed inlet of the inducer and the vertically disposed outlet side of the heat exchangers. In a preferable arrangement, the furnace includes a burner assembly utilizing a plurality of burners, each having an arcuate shape in relation to a corresponding plurality of heat exchangers, and thereby occupying a minimum of space without loss of efficiency.

Mobile home furnace

A multi-panel spacer/shipping bracket for supportively spacing at least one panel located within a compartment, the bracket comprising: a base member; an attachment member extending therefrom and attached to the compartment; and a retention member extending from the base member, and further comprising an insertion member having a slot therein for retaining a panel, the slot defining an approach opening sized to receive the panel thereinto, and a spring member, positioned relative to the slot so as to operate to urge the panel against an interior vertical wall of the slot.
