Abstract
A combustion air vent for use with an extension wall of a building includes a louvered panel substantially in the plane of the stucco wall surface. Top, bottom, left and right side panels extend from the edges of the louvered panel for a distance substantially commensurate with the thickness of the stucco wall externally of the supporting wall framing. One or more bendable tabs are disposed in selected ones of the panels and adapted to be bent to secure an insect screen adjacent the interior surface of the louvered panel. Flanges extend from one or more of the top, bottom, left and right side panels. Fastening means secure selected ones of the flanges to the framing to retain the vent in place.
Claims14
A combustion air vent for use in stucco walls, said vent comprising in combination:
- a) a box including a louvered panel, top, bottom, left and right side panels, and a flange extending from at least one of said panels;
- b) an insect screen disposed adjacent the interior of said louvered panel;
- c) at least one tab extending from at least one of said panels for retaining said insect screen adjacent said louvered panel;
- and
- d) a flange extending from each of said top and bottom panels, at least a slot extending from said top panel into the corresponding one of said flanges and a tab extending within each of said at least one slot from said top panel and adapted to be bent to a position adjacent said insect screen, at least a further slot extending from said bottom panel into the corresponding one of said flanges and a further tab extending within each of said at least further slots and adapted to be bent to a position adjacent said insect screen.
An air vent adapted to be attached to the framing of a building wall, said vent comprising in combination:
- a) a louvered panel;
- b) an insect screen adapted to be disposed adjacent said louvered panel;
- c) a plurality of tabs adapted to be bent to retain said insect screen adjacent said louvered panel;
- d) a plurality of flanges adapted to be secured to the framing to retain said vent in place;
- e) panels extending from the edges of said louvered panel for supporting said flanges;
- and
- f) each of said tabs extending from an edge of a slot disposed in at least one of said panels.
A method for mounting a combustion air vent upon framing of an extension wall, said method comprising the steps of:
- a) placing an insect screen adjacent the inside of a louvered panel, which louvered panel is supported by top, bottom, left and right panels;
- b) bending at least one tab from an edge of a slot disposed in at least one of the top, bottom, left and right panels adjacent the insect screen to retain the insect screen in place;
- and
- c) fastening at least one flange of the vent to the framing.
