A direct vent gas fireplace, comprising:

• an interior housing forming a combustion chamber;
• a top wall, rear wall, bottom wall and side walls defining an exterior housing about said combustion chamber;
• a gas burner disposed in said combustion chamber;
• a slanted wall connected to and extending between said top and rear walls, said slanted wall disposed at obtuse angles relative to said top and rear walls;
• a first pipe member orthogonally extending to an opening in said slanted wall and in fluid communication with said combustion chamber for conveying combustion products from said combustion chamber;
• means forming a first plenum having a diameter larger than said first pipe and disposed around said first pipe member and in communication with said opening in said slanted wall, said first pipe member and said first plenum defining an annular space therebetween forming an air intake duct;
• and
• a combustion air duct extending between and in fluid communication with said plenum and said combustion chamber for supplying combustion air to said combustion chamber;
• whereby the exhaust pipe and fresh air pipe of the flue pipe assembly form a 135.degree. angle and are respectively attached to said first pipe member and said plenum and can be oriented to extend away from said fireplace selectively in either a substantially vertical or horizontal direction.

A direct vent fireplace adapted for attachment to a flue pipe assembly including an exhaust pipe and surrounding fresh air pipe, said fireplace comprising:

• an interior housing forming a combustion chamber;
• a top wall, rear wall, bottom wall, side walls and front opening defining an exterior housing about said combustion chamber;
• a slanted wall attached to and extending between said top wall and rear walls and forming obtuse angles relative to said top and rear walls;
• a first pipe member orthogonally extending to an opening in said slanted wall and in fluid communication with said combustion chamber for conveying combustion products from said combustion chamber;
• means forming a plenum having a diameter larger than said first pipe and disposed around said first pipe member and in communication with said opening in said slanted wall, said first pipe member and said plenum defining an annular space therebetween forming an air intake duct;
• and
• a combustion air duct extending between and in fluid communication with said plenum and said combustion chamber for supplying combustion air to said combustion chamber;
• whereby the exhaust pipe and fresh air pipe are adapted to be respectively adapted to be attached to said first pipe member and said plenum and can be oriented to extend away from said fireplace selectively in either a substantially vertical or horizontal direction.

A direct vent gas fireplace, comprising:

• a flue pipe assembly having an exhaust pipe and fresh air pipe, said fresh air pipe having a diameter larger than and disposed around said exhaust pipe, each of said exhaust pipe and fresh air pipe having first and second tubular portions disposed at about a 135.degree. angle relative to each other;
• an interior housing forming a combustion chamber;
• a top wall, rear wall, bottom wall and two side walls defining an exterior housing about said combustion chamber;
• a gas burner disposed within said combustion chamber;
• a slanted wall attached to and extending between said top wall and rear wall, said slanted wall disposed at an angle of about 45.degree. with respect to a horizontal plane;
• a first pipe member orthogonally extending to an opening in said slanted wall and in fluid communication with said combustion chamber for conveying combustion products from said combustion chamber;
• means forming a first plenum having a diameter larger than and disposed around said first pipe,
• said first pipe member and said first plenum defining an annular space therebetween forming an air intake duct;
• and
• a combustion air duct extending between and in fluid communication with said air intake duct and said combustion chamber for supplying combustion air to said combustion chamber;
• said first tubular portions of each said exhaust pipe and fresh air pipe respectively attachable to said first pipe member and said first plenum whereby said second tubular portions of each said exhaust pipe and fresh air pipe are selectively disposed in a substantially vertical or horizontal direction.

A direct vent fireplace, comprising:

• a flue pipe assembly including an exhaust pipe and a surrounding fresh air pipe;
• an interior housing forming a combustion chamber;
• a top wall, rear wall, bottom wall and side walls defining an exterior housing;
• a slanted exterior wall attached to and extending between said top and rear walls, said slanted outer wall disposed at obtuse angles relative to said top and rear walls;
• said combustion chamber including a slanted interior wall disposed in spaced apart parallel relationship from said slanted exterior wall;
• an intermediate wall disposed between said slanted inner wall and slanted exterior wall, said intermediate wall attached to said slanted exterior wall, said intermediate wall and slanted exterior wall forming a plenum in fluid communication with said combustion chamber for supplying combustion air to said combustion chamber;
• a first pipe member orthogonally attached to said slanted inner wall and extending through said slanted exterior wall and intermediate wall, said first pipe member in fluid communication with said combustion chamber for conveying combustion products from said combustion chamber;
• and
• a second pipe member orthogonally attached to said slanted exterior wall, said second pipe member having a diameter larger than said first pipe and disposed around said first pipe member, said first and second pipe members defining an annular space therebetween forming an air intake duct in fluid communication with said plenum.

A direct vent fireplace adapted for attachment to a flue pipe assembly including an exhaust pipe and a surrounding fresh air pipe, said fireplace comprising:

• a top wall, rear wall, bottom wall and side walls defining combustion chamber, one of said walls defining said combustion chamber including an opening therein for admittance of combustion air;
• a slanted flue attachment wall attached to and extending between said top and rear walls, said slanted flue attachment wall disposed at obtuse angles relative to said top and rear walls;
• an exterior housing disposed in spaced apart relationship from said combustion chamber, said housing having an exterior bottom wall, exterior top wall, exterior back wall, two exterior side walls, an exterior front wall defining an opening, and a slanted exterior wall attached to and extending between said exterior top wall and exterior back wall, said slanted exterior wall disposed generally parallel to said slanted flue attachment wall;
• a first pipe member orthogonally attached to said flue attachment wall and in fluid communication with said combustion chamber for conveying combustion products from said combustion chamber;
• and
• means forming a plenum orthogonally attached to said slanted exterior wall, said plenum having a diameter larger than said first pipe and disposed around said first pipe member, a combustion air duct connected with said plenum and in fluid communication said combustion chamber;
• whereby the exhaust pipe and fresh air pipe are respectively adapted to be attached to said first pipe member and said plenum and can be selectively oriented to extend away from said fireplace in either a substantially vertical or horizontal direction.
