ABSTRACT:
A gas fueled direct vent fireplace has a firebox within an outer casing, the firebox having a mounting plate above the floor of the casing for mounting burner support brackets, a pilot light assembly, a gas valve and control assembly, and other conventional elements for controlling the burner. The mounting plate includes an explosion blow-out valve plate and a vacuum release plate which are spring biased to close respective ports. The valve plate opens when the gas pressure within the firebox is excessive, and the vacuum release plate opens if the release of pressure from the firebox causes the firebox to become subatmospheric. The firebox has a frontal opening which is closed by a glass access door having an extrusion at upper and lower edges and side edge protectors. The extrusions have portions which face the interior of the firebox to be grasped by latches mounted on the firebox to tightly secure the glass access door to the firebox. A gasket is bonded to the surface of the glass which faces the firebox and seals the glass against the firebox.
