Harrie Leenders HL2 Instructions for Installation, Use and Maintenance7PREPARATORY WORK AND SAFETY CHECKSIMPORTANT WARNINGThis stove must not be installed into a chimney that serves any other heating appliance.There must not be an extractor fan fitted in the same room as the stove as this can cause the stove to emitfumes into the room.ChimneyIn order for the stove to perform satisfactorily the chimney height must be sufficient to ensure an adequatedraught of approximately 15 Pa so as to clear the products of combustion and prevent smoke problems intothe room.NOTE: A chimney height of not less than 4.5 metres measured vertically from the outlet of the stove to thetop of the chimney should be satisfactory. Alternatively the calculation procedure given in EN 133841 maybe used as the basis for deciding whether a particular chimney design will provide sufficient draught.The outlet from the chimney should be above the roof of the building in accordance with the provisions ofBuilding Regulations Approved Document J.If installation is into an existing chimney then it must be sound and have no cracks or other faults whichmight allow fumes into the house. Older properties, especially, may have chimney faults or the cross section may be too large i.e. more than 230 mm x 230 mm. Remedial action should be taken, if required, seeking expert advice, if necessary. If it is found necessary to line the chimney then a flue liner suitable for solidfuel must be used in accordance with Building Regulations Approved Document J.Any existing chimney must be clear of obstruction and have been swept clean immediately before installation of the stove. If the stove is fitted in place of an open fire then the chimney should be swept one monthafter installation to clear any soot falls which may have occurred due to the difference in combustion between the stove and the open fire.If there is no existing chimney then any new system must be to the designation described above and in accordance with Building Regulations Approved Document J.A single wall metal fluepipe is suitable for connecting the stove to the chimney but is not suitable for use asthe complete chimney. The chimney and connecting fluepipe must have a minimum diameter of 150 mmand its dimension should be not less than the size of the outlet socket of the stove.Any bend in the chimney or connecting fluepipe should not exceed 45°. 90° bends should not be used.Combustible material should not be located where the heat dissipating through the walls of fireplaces orflues could ignite it. Therefore when installing the stove in the presence of combustible materials due account must be taken of the guidance on the separation of combustible material given in Building Regulations Approved Document J and also in these stove instructions.If it is found that there is excessive draught in the chimney then a draught stabiliser should be fitted. Fittingof a draught stabiliser will affect the requirement for the permanent air supply into the room in which thestove is fitted in accordance with Approved Document J (see also combustion air supply).Adequate provision e.g. easily accessible soot door or doors must be provided for sweeping the chimneyand connecting fluepipe where it is not intended for the chimney to be swept through the appliance. |
