Abstract:
A latch assembly for securing a furnace door to a furnace casing includes a latch for placement on an inside of the furnace door; a knob for placement on a front surface of the furnace door; a latch plate for placement between the latch and the knob; and a threaded screw for threadably coupling the knob to the latch. The latch plate supports the weight of the furnace door in a closed position and reduces a pinch force used for rotating the knob.
Abstract:
A refractory panel for a heat exchanger is provided having a body including a first planar surface having a plurality of refractory openings formed therein. A sidewall is arranged about a periphery of at least one of the plurality of refractory openings. The sidewall extends outwardly from the first planar surface and is configured to extend through an adjacent component into an inlet of a heat exchanger coil.

Abstract:
A plate fin for a heat exchanger is provided including a base plate having a plurality of holes formed therein. The plate fin also includes a plurality of generally annular collars. Each collar is positioned substantially coaxially within one of the plurality of holes. The plurality of first collars is substantially less than the plurality of holes such that a portion of the plurality of holes does not have a collar arranged therein.
Abstract:
A burner assembly for a gas furnace including a partition panel including an upstream side, a downstream side, at least two partition openings, and an intermediate transverse slot in communication with each of the at least two partition openings, wherein each partition opening is located adjacent to one another, and at least two burners configured to fire inward, the at least two burners operably coupled to the upstream side, wherein each burner is substantially aligned with each respective partition opening.
Abstract:
An informational label for a component of a heating ventilation and air conditioning (HVAC) unit includes a sheet including a plurality of panels foldable from an opened configuration into a closed configuration. The sheet exhibits at least one of resistance to heat or resistance to moisture of an operating environment. A closure is utilized to secure the plurality of panels in the closed configuration, and a layer of adhesive is applied to a panel of the plurality of panels to secure the informational label to an HVAC component.
