The cooker operates on the principle of equalization of natural differential pressures caused by rising warmer air, similar to the draw created by the upper portion of a fireplace, for drafting hot gases or smoke laden hot gases from the combustion source and selectively routing it through passageways into and around the various components.

A thermally insulated cooking pot consists of an outer pot and an inner pot. The inner pot is suspended within the outer pot by hanging from the top inner circumferential area of the outer pot with its own top outer circumferential area. The space between the inner and outer pots becomes an insulation cavity. The contact point between the two pots is sealed by a pliable packing ring with an L-shaped cross-section, thereby sealing the insulation cavity. This sealed insulation cavity provides excellent thermal insulation. The packing ring contains a plurality of protrusions on the surface that come into contact with the inner pot to prevent the packing ring from sticking to the inner pot. The gap formed between the packing ring protrusions and the inner pot prevents the inner pot from sticking to the packing ring.
