ABSTRACT:
A vent-free, gas fireplace for providing heat, light, and an aesthetic view includes an outer shell arranged with a top panel, front panel, rear panel, and left and right side panels and a combustion chamber positioned within the outer shell so as to define a plurality of air chambers. The combustion chamber is arranged with a primary combustion portion for initial combustion of the gas which is supplied to the fireplace and a secondary combustion portion which includes a catalytic converter and which is designed to bum the emissions from the primary combustion portion. The plurality of air chambers defined between the outer shell and combustion chamber include a rear chamber and a top chamber and positioned within the top chamber is a heat shield which defines an interior volume. The interior volume of the heat shield is in flow communication with the rear chamber so as to direct air through the heat shield and out into the room. The heat shield helps to maintain a lower temperature for the top panel of the outer shell. The front panel for the outer shell, which includes the front panel for the combustion chamber, defines a first air inlet for combustion air, a second air inlet for cooling air, a first air exhaust in flow communication with the secondary combustion portion, and a second air exhaust in flow communication with the top chamber.
