The gaps between the floors, walls, partitions and dressing should be provided with the filling of non-combustible materials. Distance overlap between the top of the furnace, made of three rows of bricks and roof of combustible or slow-burning material that is protected by a steel grid, stucco, or steel sheet on asbestos board thickness of 10 mm should be take 250 mm for the periodic furnace stoves and 700 mm – long burning stoves, and unprotected ceiling – respectively 350 mm and 1000 mm. For furnaces with a ceiling of two rows of bricks, the distances should be increase by 1.5 times. Distance between the top metal furnace with insulated roof and ceiling should be protected by 800 mm, and the oven with neteploizolirovannym overlap and unprotected ceiling – 1,200 mm. Metal flue pipes that are laid parallel to the ceiling or the walls and partitions of material flammability groups G3, G4, must be from a distance of not less than 0.7 m – no insulation on the pipe, not less than 0,25 m – with isolation, which prevents the temperature rise on the outside surface of more than 90 C To maintain a cost-effective and uninterrupted operation of the heating equipment should be regularly checked and cleaned chimney with soot and debris: before the heating season, according to its end, but not less than 3 times per year.
