Abstract: A boiler gas flow distribution fin includes an elongated flow distribution fin protruding from a back wall of a flow distribution channel into a hot gas flow path from a boiler combustion chamber. The flow distribution fin can include a leading segment with a leading ridge, a medial segment with a medial ridge, and a trailing segment with a trailing ridge. A gap between the fin ridges and a set of convective fins in an adjacent flue passageway segment can vary from a larger gap at the leading ridge to a smaller gap at the trailing ridge, transitioning along the medial ridge. The flow distribution fin can aid in directing a hot gas flow from a combustion chamber into the flue passageway segment, resulting in a substantially balanced mass flow rate through each of a series of flue passageway sections.

Abstract: A panel mount electrical connector in a burner enclosure panel includes an electrical connector receptacle mounted to an enclosure panel of a fuel-burning combustion device, an internal wiring harness, an electrical connector plug that matches the receptacle, and an external wiring harness configured to be coupled to a separate appliance. The panel mount electrical connector facilitates easy and quick disconnection of the burner electrical wiring at the burner enclosure panel, making installation, removal, and maintenance less difficult.

Abstract: A system for securing a combustion device to a support member includes a leg attached to the combustion device, the leg configured to rest against a member and to be fastened to the member by a fastener and an intermediate member placed in a hole in the leg, wherein the intermediate member is fastened to the support member by a fastener, and the leg is fastened to the support member via the intermediate member. A method for preparing a combustion appliance for shipping is provided. The method includes forming a leg for the combustion appliance, placing the leg on a shipping member, inserting an intermediate member into a hole in the leg and fastening the leg to the shipping member with a fastener extending through the intermediate member, wherein a portion of the leg is located between the intermediate member and the shipping member.

Abstract: A control frame for a boiler includes a control mounting surface and a control panel. The control frame can be formed from a single piece of sheet metal, such that the control mounting surface and the control panel form a single undivided unit. In addition, the control frame can structurally support a boiler enclosure. The control mounting surface can include mounting interfaces for a control device, an optional microcontroller and wiring terminal strips. The control panel can also include cutouts or mounting interfaces for instrumentation or other control devices. The control frame can further include a latch interface to hold a separate cover panel in place.

Abstract: In accordance with one embodiment of the present invention, a pivoting and sliding member is provided. The pivoting and sliding member includes a housing covering controls for a combustion appliance, a first and second pivot pin attached to the housing in a substantially parallel manner having sufficient strength to permit the housing to pivot and slide about the first and second pivot pins, and an elongated receiving slot configured to receive one of the first or second pivot pins and dimension to permit at least one of the first and second pivot pins to pivot within and slide along the elongated receiving slot. A method of manipulating a control cover on a combustion device is provided.
