ENGLISH RAIS - manual for Q-BIC & Q-BIC insert8ChimneyThe chimney is the driving force which makes the stove function. In order for the stove toperform satisfactorily the chimney height must be sufficient to ensure the correct draughtof 14 to 18 Pa so as to clear the products of combustion and prevent problems of smokeemanating into the room when firing.NOTE: A chimney height of not less than 4.5 metres measured vertically from the outletof the stove to the top of the chimney should be satisfactory. Alternatively the calculationprocedure given in BS 5854:1980 may be used as the basis for deciding whether a particularchimney design will provide sufficient draught.The outlet from the chimney should be above the roof of the building in accordance with theprovisions of Building Regulations Approved Document J.If installation is into an existing chimney then it must be sound and have no cracks or otherfaults which might allow fumes into the house. Older properties, especially, may have chim-ney faults or the cross section may be too large i.e. more than 230 mm x 230 mm. Remedialaction should be taken, if required, seeking expert advice, if necessary. If it is found necessaryto line the chimney then a flue liner suitable for solid fuel must be used in accordance withBuilding Regulations Approved Document J.Any existing chimney must be clear of obstruction and have been swept clean immediatelybefore installation of the stove. If the stove is fitted in place of an open fire then the chimneyshould be swept one month after installation to clear any soot falls which may have occurreddue to the difference in combustion between the stove and the open fire.If there is no existing chimney then either a prefabricated block chimney in accordance withBuilding Regulations Approved Document J or a twin walled insulated stainless steel flue toBS 4543 can be used. These chimneys must be fitted in accordance with the manufacturer’sinstructions and Building Regulations.A single wall metal fluepipe is suitable for connecting the stove to the chimney but is notsuitable for using for the complete chimney. The chimney and connecting fluepipe musthave a minimum diameter of 150 mm and its dimension should be not less than the size ofthe outlet socket of the stove which is 150 mm in diameter. Any bend in the chimney or con-necting fluepipe should not exceed 45°. 90°bends should not be used.Combustible material should not be located where the heat dissipating through the wallsof fireplaces or flues could ignite it. Therefore when installing the stove in the presence ofcombustible materials due account must be taken of the guidance on the separation ofcombustible material given in Building Regulations Approved Document J and also in thesestove instructions.
