Abstract
A device to prevent indoor release of carbon monoxide and smoke from indoor combustors (stoves, furnaces, fireplaces, etc.). The device is based on a discovery that safe operation of indoor burners requires the air pressure in the room housing the burner to be relatively high in order to prevent generation of reverse chimney flow and indoor release of exhaust gas (smoke and carbon monoxide), which are dangerous to building occupants. This device solves the problem by increasing the building internal pressure.
