Abstract
A draft hood is provided for mating alignment with a fireplace assembly. The mating alignment is facilitated by the location of alignment hardware fixed to the rear surface of the fireplace and to the inside of the draft hood. In use the hardware permits alignment of the draft hood in a fireplace enclosure without the need to see the fitting, without the need for a long run-in slide, and without the need vertically to pivot the draft hood on installation or to pull the flue termination forward of the firebox flue before attachment. For this purpose an updraft detection warning spill tube may also function as one of the alignment fittings since it is, due to its function, located near or at the junction of the draft hood and fireplace.
