Abstract: 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.

Abstract: A burner assembly for use adjacent an igniter element in a gas appliance includes a top plate configured to form the geometric top half of at least one burner, and a bottom plate configured to form the geometric bottom half of at least one burner. The top plate and the bottom plate are joined together to form a burner and a burner carryover. An igniter air shield extends from either the top plate or the bottom plate such that the igniter air shield diverts secondary combustion air flowing around the burner and the adjacent igniter element.

Abstract: A mounting structure (34) for receiving a sensor (18) having a sensing portion (26) and a base portion (30) includes a substantially flat sheet of material (20) having a first surface (20a), a second surface (20b) opposite the first surface (20a), and an aperture (36). The aperture (36) is configured such that the sensing portion (26) of the sensor (18) is passable through the aperture (36), and the base portion (30) is not passable through the aperture (36), but instead rests on the first surface (20a). The mounting structure (34) also includes a pair of tabs (38) that extend in a downward direction away from the second surface (20b) of the sheet of material (20) and are configured to immobilize the sensor (18) within the aperture (36).

Abstract: An outdoor unit for an air conditioner/heat pump is provided with a bracket which is attached to the tube sheet of the heat exchanger coil for routing the electrical leads from the electronic components within the unit to a control box located outside thereof. The bracket is mounted without fasteners and is preferably clipped onto a planar structure on the tube sheet by way of opposing tabs on the bracket. The bracket is preferably secured to the planar wall by way of dimples that engage with holes formed in the planar wall.

Abstract: Apparatus for mounting one or more component parts of a unit in assembly. The apparatus includes a mounting plate containing one or more extruded holes each having a raised lip surrounding the hole which protrudes upwardly from the top surface of the plate for receiving a threaded fastener that is used to secure a part to the bottom mounting surface of the plate. An endless depression surrounds each hole which also protrudes outwardly from the top surface of the plate. The size and shape of the depression is such that the plate area surrounding the fastener receiving hole is strong enough to resist high impact loads.

Abstract: 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.

Abstract: 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.

Abstract: A high efficiency furnace having a heat exchanger and an inducer fan housing attached to the flue gases exit of the heat exchanger to draw flue gases out of the exchanger and force the gases out of the furnace under pressure through a venting system. A condensate return channel is provided for directing condensate developed in the vent system back into the inducer housing where it its removed from the furnace by a drain.
