Abstract: A fireplace latch system has a pivotable latch retained within a latch retainer. One or more springs between the pivotable latch and latch retainer bias the latch towards two stable positions, an opened position and a closed position. In the closed position, one or more surface contacting elements extend through the latch retainer and exert a force on a frame for a glass panel to secure the glass panel and frame to the fireplace. The latch system allows the glass panel and frame to move outwards to release pressure in the event of an explosion within the combustion chamber of the fireplace.

Abstract: A power vented fireplace uses a single air inlet to pressurize a staging area from where air is distributed along a passageway between viewing panels to cool them as well as into the combustion chamber as a supply of combustion air. A partial restriction at an inlet to the passageway ensures that sufficient air is directed into the combustion chamber. The inlet to passageway may be adjustable to vary the extent of the restriction. Pressure differential switches may be used to ensure balanced operation of the fireplace.

Abstract: A manufactured fireplace is adapted for flush-mounting within a pre-sized opening in a wall structure without the need to double the layers of drywall surrounding the opening. The fireplace metal facing panels are manufactured to be flush from the fireplace window to an outer edge of the panels. Non-combustible board is attached over the panels during manufacture of the fireplace, obviating the need for installers to size, cut and attach non-combustible board to the fireplace panels on site then to attempt to achieve a flush-mounting by doubling up the layer of drywall surrounding the fireplace opening. The fireplace including the attached non-combustible board facing is shipped to a work site for installation.
