A vent assembly characterized by a rear member having a perforated rear surface, and a front member having a front surface formed into a number of louvers. The side portions and bottom portions of the rear member are bent into L-shaped flanges which engage the inner dimensions of the front member. The front member has a top portion and side portions which are bent into L-shaped flanges to provide flashing for the assembly. The front member and rear member are permanently attached together to form a single unit, and a number of units can be vertically stacked to provide vent structures of various heights.

Louvered vent

A spark arrester characterized by a fixed base assembly attached over the top of a chimney, a pivot assembly attached to the fixed base assembly, and a rotatable assembly rotatably coupled to the pivot assembly. The rotatable assembly is substantially cylindrically shaped having perforate sidewall portions and a perforate top portion. A vane portion of the rotatable assembly orients a windward section of the sidewall portion towards the wind, and a deflection plate attached within the sidewall portions proximate the windward section deflects the prevailing wind up through the top portion of the assembly. Co-action between the upwardly deflected wind and the underside of the vane portion creates a low pressure area over the top portion which substantially increases the draught of the chimney, resulting in reduced risk of chimney fires and an increased burn rate for airborne embers and sparks.
