Draft hood assembly

摘要

A draft hood assembly and method are provided for installation of a gas fireplace insert to the flue pipe of a fireplace chimney. The insert is for connection between a gas fireplace insert and a chimney flue pipe, the gas fireplace insert having an explicitly-described structure. The draft hood assembly includes a base plate, the base plate having an aperture therein, the aperture being alignable with the exhaust opening which is provided in the upper panel of exhaust channel of the fireplace insert. A hollow superstructure is integrally-mounted on the base plate, the superstructure body being of an explicitly-described structure, but further wherein an upper front plate terminates a spaced-distance above the base plate, and the bottom plate delineates an aperture alignable with the aperture in the base plate. The hollow superstructure body also includes a lower, rear exhaust chamber defined by an explicitly-described structure, which is in gaseous communication with the firebox. An upper, front exhaust chamber of an explicitly-described structure is in gaseous communication with the lower, rear exhaust chamber. An upper exhaust opening is provided in the top plate of the superstructure body, the upper exhaust opening leading from the upper, front exhaust chamber of the superstructure to the chimney flue pipe, the upper exhaust opening being situated forward of, and completely forwardly offset from, but being in gaseous communication with, the lower rear exhaust chamber. A longitudinally-curved deflector is secured to the lower forward plate, the longitudinally-curved deflector extending upwardly from the base plate and terminating a spaced-distance below the top panel of the superstructure body. Positioning bars are provided to enable securement of the draft hood assembly to the top panel of the firebox.
