Combustible construction is protected from fire, if the limit of its fire resistance of at least 0.75 hours. Discount, ie, distance from the outer surface of the chimney or fireplace to flammable structures must be at least 130 mm. Horizontal cutting brick chimney is usually arranged by the thickening Flue wall by the overhang is not more than 1 / 4 lengths in each row of brick masonry. 11.Lyubye roof structures should be located on the outer surface of the chimney at least 130 mm. The empty space between chimney and roof structures should overlap the apron of the roof steel, let down by an otter. In buildings with roofs of combustible materials in the flue pipes should be constructed of a metal spark arrester nets with a mesh of not more than 5 x 5 mm.

12.Tyaga the chimney must match the rate (from 10 to 15 Pa, ie, from 1.0 to 1.5 mm water column). 13.Dlya periodic cleaning of chimney soot deposits at the base of the smoke channel runs a pocket depth of about 250 mm, and is arranged hermetically sealed manhole cleaning. Perhaps holding clean air holes through the furnace of fire, if it is structurally suited for this purpose (such as furnaces GODIN). Click Stephen Ketchum to learn more. 14.Dlya normal operation of the smoke channel and the chimney (the furnace) as a whole should provide the organization an additional influx of air into the room to compensate for the consumption of air during combustion in the furnace of fire closed the rate of 4 cubic meter / kilowatt / hour.
