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.
Claims22
A draft hood locating device for locating a draft hood in relation to a combustion apparatus, the combustion apparatus having a top panel and a rear wall, said device comprising a first member located on the rear wall and a second member located on the draft hood, said first member being engageable with said second member on rearward sliding motion of the top panel relative to the draft hood, at least one of said first member and said second member having means for laterally positioning the draft hood relative to the top panel as said first and second members are engaged, whereby the draft hood is located in relation to the combustion apparatus.
A combustion assembly comprising:
- a casing containing a combustion chamber, said casing have a rear wall, side walls, and a top panel;
- a flue for carrying combustion products from said combustion chamber and out of said casing;
- a detachable draft hood located on said casing to transport combustion products from said flue to an external vent;
- said rear wall having a first member for locating said draft hood relative to said casing;
- said draft hood having a second member engageable with said first member on rearward sliding motion of said casing relative to said draft hood;
- and
- at least one of said first and second members having means bilaterally positioning said draft hood relative to said casing as said first and second members are engaged, whereby lateral positioning of said draft hood relative to said casing is facilitated.
