BS 8511-2010 pdf free download.Code of practice for the installation of solid fuel heating and cooking appliances in small craft.
7.1 General precautions
Care should be taken to prevent combustible materials in the surrounding structure of the craft being damaged or ignited when they are subjected to radiated, convected and conducted heat from the appliance. Any combustible material in the vicinity of an appliance, whether exposed or covered, e.g. by tiles, should be protected to ensure that its surface temperature does not exceed 65 °C above ambient temperature.
For appliances tested according to BS EN 13240 orBS EN 12815 (with or without the manufacturer’s heat shields) the installation arrangements and clearances of combustible materials from the sides and rear should either:
a) follow the manufacturer’s installation instructions; or
b) for appliances with a declared distance from combustibles of 700 mm or less to the rear and sides, as determined by the temperature safety tests described in BS EN 13240 or BS EN 12815, follow either of the installation examples A or B described in 7.2 and 7.3 respectively, and shown in Figures 8 to 11 inclusive.
For all other appliances, verification of the safe distances from combustible surfaces, using the proposed installation arrangement. should be made by following the temperature safety test procedures described in BS EN 13240 or BS EN 12815, as appropriate.
7.2 Installation example A
Non-combustible insulation board should be affixed to the structure to the sides and rear of the appliance, with an air gap maintained to separate the board from the structure. The air gap may be left open or be closed by non-combustible material at top and sides. The board should extend to at least the extremities of the hearth horizontally and to at least 200 mm above the top surface of the appliance.
NOTE 1 Examples of suitable non-combustible insulation board include those made from calcium silicate, gypsum and vermiculite, but care ought to be taken to ensure that the board does not contain reinforcements made of combustible material.
Attachment of the insulation board to the structure should be at the corners of the board, using non-combustible fixings and with non-combustible spacers to maintain the gap between the board and the structure.BS 8511-2010 pdf free download.
