Abstract
A novel draft hood for mounting on top of a gas conversion unit to form an adaptor and coupler between the gas conversion unit and a chimney includes a box structure having a guide flange and a plurality of positioning flanges thereon. A down draft diverter is installed inside of the box structure juxtaposed the exhaust outlet in the top of the draft hood. A novel spring alignment means including control rod are inserted through the top of the draft hood and employed as a positioning and aligning device maneuverable from the inside of the combustion chamber of the gas conversion unit and employed to apply a spring force to the draft hood which couples it to the gas conversion unit.
