Abstract: A shelf and slideable mount, which is made up of, but not necessarily limited to, the following components: (1) a mount which features anchor nail platforms and/or holes which accommodate screws, and angled sides, and (2) a shelf which features a horizontal plane and a vertical cover portion which slides over the mount.

Abstract: A fuel-fired heating appliance comprises a fuel source, an air source, a chamber in which fuel and air mix, a burner downstream from the mixing chamber, an igniter proximate the burner, a heat exchanger, a blower and a flue pipe. An ambient air inlet may be defined by at least one of the outlet end of the blower and the flue pipe extending between the interior of the flue pipe and an area ambient to the flue pipe. A flow rate of combustion gas may be controlled to a level below a steady-state flow rate during appliance warm-up.

Abstract: A fuel-fired heating appliance has two fuel flow paths to a burner, each actuatable to a closed state and to an open state. A heat exchanger is in fluid communication with an area proximate the burner. A controller executes the steps: (a) while the first fuel flow path is closed, opening the second flow path; (b) following ignition of fuel flowing from the second flow path, opening the first fuel flow path; and (c) following step (b), closing the second fuel flow path while opening the first fuel flow path.

Abstract: A fuel-fired heating appliance comprises a burner and a first housing adjacent the burner so that an interior of the first housing receives combustion gasses from combustion at the burner. A heat exchanger defines a second housing with an inlet proximate an outlet of the first housing so that the inlet of the second housing receives combustion gasses from the outlet of the first housing, and wherein the first and second housings attach at an interface. A barrier extends within, and across an interface between, the outlet of the first housing and the inlet of the second housing and defines a thermal resistance that inhibits heat transfer from the combustion gasses to the interface.

Abstract: A method and device for moving racked tubulars, such as pipe and casing joints on pipe racks at oil and gas well sites. The pipe moving tool comprises a wheel assembly with a long straight handle. The wheels fit inside the pipe, which is then moved by simply pushing or pulling the handle forward or backward, as needed. Several wheel assemblies of different diameters may be used interchangeably with a single handle. An extension handle also may be included. The use of this tool makes moving the pipe safer as the worker's hands are not exposed to injury. Additionally, the handle on the tool makes it possible to easily and more safely reach and move shorter pipes racked above or below longer pipes in a multi-level pipe rack; it is not necessary for the worker to lean over or under the longer pipes.
