Combustion of fuel in boiler rooms requires oxygen. Air for maintenance of burning can directly get from the room of a boiler room or on a special airintaking pipe from the street. In a feather case the copper has the open combustion chamber, in the second - closed. In the closed chamber, products of combustion are forcibly taken away via the gas flue on the street. The copper with the open combustion chamber requires a stationary vertical flue in which natural draft is created. Coppers with the closed combustion chamber demand special pipes for an intake of air and a conclusion of exhaust gases. But the gas flue can be brought through a boiler room wall to the street at once, without equipping a flue if it was not provided at once. During the work, coppers with the closed combustion chamber publish less noise.
