Abstract: A fireplace assembly is disclosed and includes a smoke chamber, a firebox, a throat in fluid communication with and linking the smoke chamber and the insulated firebox and a divider positioned within said throat and defining a front air channel and a rear air channel within the throat. The fireplace assembly of the present invention offers reductions in particulate emissions when compared to traditional open-burning fireplaces and has comparable particulate emissions to wood stoves and built-in wood stoves.

Abstract: Disclosed is a flashing for weatherproofing an aperture made in an inclined roof to allow passage of a vertical member such as chimney through the inclined roof. This flashing has a base member adapted to be mounted over the aperture and a surrounding member that is tubular in shape and extends upwardly from the base member to fit around the vertical member. The base member comprises a covering panel of quadrilateral shape having a top edge adapted to be positioned on an upper part of the inclined roof, a bottom edge adapted to be positioned on a lower part of the inclined roof, two opposite side edges and an opening large enough to allow passage of the vertical member therethrough. A bottom side wall projects downwardly from the bottom edge of the covering panel and two lateral side walls respectively extend downwardly from the opposite side edges of the covering panel and sidewardly from the bottom side wall in a tapering fashion.
