ABSTRACT:
A forced air gas fired heating device may be utilized as a stove insert for a conventional open fireplace or in an alternative embodiment may be formed with a double walled construction for use as a free standing unit. In both embodiments a gas burner adjacent a bottom portion of the housing heats an air space within the housing. A room air inlet conduit traverses back and forth across the heated air space and communicates with an air distribution chamber in an upper portion of the housing. A plurality of room air outlet conduits extend outwardly from the distribution chamber through a front wall of the housing. A heat exchanger is suspended from each of the room air outlet conduits and includes a hollow body portion in fluid communication with the associated air outlet conduit. Each of the heat exchangers has an enclosed longitudinally extending corrugated heat conductive metal plate and terminates in a bottom heat conducted metal plate deposed adjacent the gas burner. Room air is inducted through an air intake opening in the side of the housing, through an air filter and through the air inlet conduit to the air distribution chamber. Heated air is then exhausted through the air outlet conduits through the front of the housing. Conventional thermostatic controls may be utilized and a pressurized gas supply tank may be provided in the housing interior. This enables the device to be utilized in campers and in remote cabins.
