Abstract
A direct vent fireplace includes a heat deflecting baffle comprised of a base member attached to the front top edge of the fireplace and an extension member telescopically attached to the base member. Each end of the extension member includes a vertical flange with a track. The base member includes a vertical flange which is received in the track along with a catch means to permit selective movement of the extension member from a retracted position to a fully extended position or to positions there between.
Claims16
A fireplace defined by a combustion chamber bounded by a plurality of walls, at least one wall comprising a front wall facing room air to be heated, said front wall having a top edge and a bottom edge;
- first plenum means for introducing air for combustion into said combustion chamber;
- second plenum means for exhausting hot exhaust gases from said combustion chamber;
- means including a blower for introducing said room air into a third air circulation plenum which creates heated room air from heat exchange contact with said second plenum means;
- at least one opening at the top of said front face below said top edge to exhaust said heated room air outward of said front wall;
- and
- a separate heat deflecting baffle attached contiguous to said top edge, above said at least one opening, and extending outwardly and downwardly at an angle less than 90° to said front face whereby said heated room air is deflected downwardly, wherein said heat deflecting baffle comprises a base member attached to said top edge and an extension member telescopically attached to said base member.
A fireplace defined by a gas fired combustion chamber bounded by a plurality of walls, at least one wall comprising a front wall facing room air to be heated, said front wall having a top edge and a bottom edge;
- first plenum means within said walls for introducing air for combustion into said combustion chamber;
- second plenum means within said walls for exhausting hot exhaust gases from said combustion chamber;
- means for introducing said room air into a third plenum within said walls which creates heated room air from heat exchange contact with said second plenum means;
- at least one opening at the top of said front face below said top edge to exhaust said heated room air outward of said front wall;
- and
- a heat deflecting baffle comprises a base member attached to said top edge above said one opening and an extension member telescopically attached to said base member, each end of said extension member includes a vertical flange with a track, and wherein said base member includes a vertical flange which is received in said track, and catch means to permit selective movement of said extension member from a retracted position to a fully extended position and to positions there between;
- and
- wherein said catch means is a spring loaded ball or bullet type attached to said vertical flange of said base member, and said vertical flange of said extension member includes a plurality of spaced openings to receive said ball or bullet catch.
A direct vent fireplace defined by a combustion chamber bounded by a plurality of walls, at least one wall comprising a front wall facing a room to be heated, said front wall having a top edge;
- at least one longitudinal and horizontal opening above said combustion chamber along said front wall and below said top edge for exhausting heated air into said room;
- a heat deflecting baffle comprises a base member attached to a top edge of said opening;
- and
- an extension member telescopically attached to said base member, to permit selective movement of said extension member downwardly and outwardly from and between a retracted position to a fully extended position.
