Abstract

An unvented gas-log fireplace is formed from a sheet metal member bent to form side and rear panels. A pair of spaced apart sheet metal plates are connected between the side panels and have rear edges spaced from the rear panel. The rear edges of the plates are bent to form lips extending in a direction toward the opposite plate. Bracket members are secured to the plates adjacent the side panels. A rear refractory member is positioned between the plates in engagement with the lips, and side refractory panels are positioned in abutment with a respective side sheet metal panel and held in place by the bracket members, the side ceramic panels abutting the rear ceramic panel at the sides thereof. An air duct is formed above the top plate, and a front face assembly having upper and lower grids permits air to flow beneath the lower plate, upwardly between the rear ceramic panel and the rear sheet metal panel, and over the upper plate, below a top panel, the front face assembly having rearwardly extending ledges which provide support for the plates adjacent the front edges thereof.
