A vent free gas fireplace comprises a housing and a firebox within the housing spaced-apart from the housing walls to provide top, bottom, rear and side plenums. The side plenums are divided into upper and lower side plenums. Room air enters the lower side plenum and passes into the rear plenum, the combustion chamber and the upper side plenum. Exhaust gases pass from the combustion chamber through a catalytic converter and into the top plenum. The hot exhaust gases are combined with room air from the rear plenum and pass into the upper side plenums, combining with additional room air, and then out into the room.
