Claim 1
Independent Claim
290 words
A zero clearance fireplace of the type adapted to be installed against an outside wall of an interior space to be heated, comprising: a box shaped fireplace having six walls comprising four substantially vertical walls, a top wall and a bottom wall, at least two of said four vertical walls having an airtight glass side wall connected to the sides of the fireplace structure, one of the remaining side walls or the top wall having an exhaust connection for insertion through an outside wall of the space to be heated, a combustion chamber in said box shaped fireplace located within and spaced away from the outer dimensions of said six walls, said vertical side wall which is adapted to be placed against an outside wall having a plenum into which fresh outside air is drawn to provide on of a plurality of heat insulating sub walls, said outside air insulating subwall being connected to fresh air supply means in the bottom wall of said fireplace, said fresh air supply means in said bottom wall having openings therein communicating with a gas burner system to provide sufficient outside combustion air to promote complete efficient combustion, duct means having elongated apertures therein along the side edges of the vertical side walls which are provided with glass panels to provide cooling air for said glass side walls in said combustion chamber, said duct means being coupled to said outside air subwall, and said top wall having a tapered shape subwall which diverts the exhaust gases nonreversibly from said gas burner system in said combustion chamber and said cooling air from along said glass side walls at high velocity into said exhaust stack to generate a high draft aspiration effect through said combustion chamber.

A zero clearance fireplace of the type adapted to be installed against an outside wall of an interior space to be heated, comprising: a box shaped fireplace having six walls comprising four substantially vertical walls, a top wall and a bottom wall, at least two of said four vertical walls having an airtight glass side wall connected to the sides of the fireplace structure, one of the remaining side walls or the top wall having an exhaust connection for insertion through an outside wall of the space to be heated, a combustion chamber in said box shaped fireplace located within and spaced away from the outer dimensions of said six walls, said vertical side wall which is adapted to be placed against an outside wall having a plenum into which fresh outside air is drawn to provide on of a plurality of heat insulating sub walls, said outside air insulating subwall being connected to fresh air supply means in the bottom wall of said fireplace, said fresh air supply means in said bottom wall having openings therein communicating with a gas burner system to provide sufficient outside combustion air to promote complete efficient combustion, duct means having elongated apertures therein along the side edges of the vertical side walls which are provided with glass panels to provide cooling air for said glass side walls in said combustion chamber, said duct means being coupled to said outside air subwall, and said top wall having a tapered shape subwall which diverts the exhaust gases nonreversibly from said gas burner system in said combustion chamber and said cooling air from along said glass side walls at high velocity into said exhaust stack to generate a high draft aspiration effect through said combustion chamber.
Claim 3
Dependent Claim
35 words
A zero clearance fireplace as set forth in claim 1 which further includes diversionary baffle means cooperating with said tapered shaped subwall to promote high velocity exit of said exhaust gases into said exhaust stack.
Claim 4
Dependent Claim
72 words
A zero clearance fireplace as set forth in claim 1 wherein said bottom wall, the vertical side wall which is adapted to be placed against said outside wall and said top wall are each provided with a subwall plenum connection thereto to form a heat exchanger for taking in room air to be heated and exhausting heated room air through the plenum in the top wall into the room to be heated.
Claim 5
Dependent Claim
40 words
A zero clearance fireplace as set forth in claim 3 which further includes side wall plenums operatively connected to said plenum in said top wall and having exhaust apertures therein for exhausting heated air into said room to be heated.
Claim 6
Dependent Claim
38 words
A zero clearance fireplace as set forth in claim 3 wherein said side wall plenums are connected to the top and to the vertical subwall plenums of said heat exchanger only on the side walls having glass panels.
Claim 7
Dependent Claim
32 words
A zero clearance fireplace as set forth in claim 1 which further includes a mesh glass protector mounted on the side of said fireplace over said glass in said glass side wall.
Claim 8
Dependent Claim
31 words
A zero clearance fireplace as set forth in claim 6 wherein said mesh glass protector comprises a pair of vertical structural frame members and a horizontal structural sheet member connected thereto.
Claim 9
Dependent Claim
37 words
A zero clearance fireplace as set forth in claim 7 wherein said horizontal structural sheet member is connected to and provides support for a substantially invisible mesh screen arranged parallel to and separated from said glass panel.
Claim 10
Dependent Claim
24 words
A zero clearance fireplace as set forth in claim 1 wherein said duct means comprise elongated ducts extending along the sides of said sidewalls.
Claim 11
Dependent Claim
25 words
A zero clearance fireplace as set forth in claim 1 wherein said duct means comprises a duct along the outside walls of two parallel subwalls.
Claim 12
Dependent Claim
34 words
A zero clearance fireplace as set forth in claim 10 wherein said duct means further comprises a duct perpendicular to and connected to the ducts along the outside walls of said two parallel subwalls.
Claim 13
Dependent Claim
36 words
A zero clearance fireplace as set forth in claim 11 wherein said duct perpendicular to and connected to the ducts along the outside walls of said two parallel subwalls comprises a duct open on two sides.
Claim 14
Dependent Claim
39 words
A zero clearance fireplace as set forth in claim 12 wherein said duct open on two sides opens into an elongated slot on one side and opens into said ducts along said outside walls on the other open side.
