Abstract: A stove comprises a firebox formed of two U-shaped interfitting members of steel plate and a U-shapted one piece base. Dual primary and secondary draft air channels extend along the bottom of the firebox from front to back immediately underneath the fire and upwardly at the rear of the firebox. A first or larger channel provides primary combustion air to the fire and the second channel extends farther upwardly to the region where volatile gases would enter the flue to secure more complete combustion thereof. The dual draft channels are controlled by an automatic draft device at the front of the stove through which the draft air is introduced. A heat shield at the rear of the stove cooperates with the one piece base for delivering heated air forwardly to the living area in front of the stove.
