PRE-INSTALLATION CHECKS
It is important that adequate ventilation exists and the flue or chimney system that is to be used is in good working condition. Products of combustion that enter the room could be a serious health risk. Before installation of this product we recommend that the flue or chimney system and ventilation requirements are inspected by a competent person, and passed as suitable for use with the appliance to be fitted. In particular the following should be checked:
1.FLUE OR CHIMNEY
1.1The construction of the Flue or Chimney system should meet the requirements of the Building Regulations with sizes as shown on the next page.
1.2An approved factory made system suitable for Solid Fuel use, complying with BS 4543: Part 2, may be used when installed to the requirements of BS 7566: Parts 1 to 4, the manufacturer’s instructions and the requirements of Building Regulations.
1.3New masonry chimney systems built with clay or concrete liners or
1.4A flexible flue liner system may be used, if it is independently certified for use with solid fuel systems, and is installed according to the manufacturer’s instructions and the requirements of Building Regulations. If an appliance is being replaced on an existing flexible flue liner system, the liner system should be replaced, unless it can be proved to be recently installed and can be seen to be in good condition.
1.5Do not connect to systems containing large voids or over 230mm square (9" square).
1.6The minimum height of the flue or chimney must be 4.5m (15') when measured from the hearth to the top of the flue, with no horizontal sections and a maximum of 4 bends with angles of less than 45 degrees.
1.7The flue exit from the building should be positioned to comply with the requirements of the Building Regulations.
1.8Any existing flue should be confirmed as suitable for the new intended use, as defined in the Building Regulations.
1.9Any existing flue or chimney system must be inspected and swept by a NACS registered (GB only) chimney sweep, to confirm that the system is structurally sound and free from any obstructions.
1.10Suitable access should be provided to enable the collection and removal of debris.
1.11Provision should be made to sweep and inspect the flue when the appliance is installed.
1.12No other heating appliances should be connected to, or share, the same flue or chimney system.
1.13Check the flue draught. This should be done with all windows and doors closed and any extraction fans in this or adjoining rooms running at maximum speed. (See next section for additional ventilation requirements)
