BS 8511:2010 pdf download.Code of practice for the installation of solid fuel heating and cooking appliances in small craft.
4.3 Cookers
For craft intended for use on rough waters, an appliance with griddle plates, hot plates or boiling rings should be fitted with a fiddle rail constructed of metal. It should be of sufficient robustness and height to retain the cooking utensils in the event of the craft experiencing significant waves or wash.
5 Installation — General requirements
5.1 Siting appliance
Appliances should not be sited where they may cause obstruction. particularly to passages and escape routes. They should not be positioned where they could create a fire hazard or damage surrounding materials or fold-away furnishings such as beds and tables, whether these are folded away or in position for use.
NOTE I it is advisable to avoid a location near to a stepped entrance There should be no free-hanging combustible material, such as curtains or blinds (whether in their extended or folded-back positions), capable of coming within the safe distance specified by the manufacturer or, if no distance is specified, within 600 mm of the appliance and any uninsulated connecting flue pipe.
The appliance should be located so as so provide the best possible heat distribution throughout the space it is intended to heat.
NOTE 2 The layout of the space to be heated will affect the location of the appliance, but a central location within the space may g,ve a more even heat distribution and thus be preferable.
5.2 Competent person
The appliance, connecting flue pipe and chimney should be installed by, or under the responsibility of, a competent person.
5.3 Securing appliance
To prevent its movement the appliance should be securely fastened either to the hearth or to the structure of the craft. Fixings should be of adequate strength to prevent appliance movement The manufacturer’s appropriate recommendations for fixing should be followed.
NOTE I Movement of the appliance can occur for a variety of reasons such as vigorous operation of the de-ashing mechanism, thermal expansion and contraction, and movement of the craft particularly caused by waves. wash and collisions.
NOTE 2 Suitable methods to secure the base of the appliance to the hearth include using adequately sized non-combustible fixings.
6 Hearth
Hearths should be designed and constructed of suitable robust and non-combustible materials, which can support the weight of the appliance. They should be of appropriate dimensions such that, in normal use, they prevent appliances setting fire to the craft’s fabric and furnishings, and limit the risk of people coming into contact with the appliance. The size of the hearth should be such that the proximity of the appliance to its edges will pevent damage to, or ignition of, other parts of the craft, e.g. flooi coverings such as carpets, rugs and wood laminates.
The non-combustible hearth should be permanently fixed to prevent movement. The hearth should be designed to accept and transfer into the structure, without deflection or cracking, the thermal stresses and statk loads imposed during use and the dynamk loads encountered during transport and use.
The required hearth design and/or construction is dependent on the performance of the appliance and should be installed as follows.
a) For appliances tested according to 85 EN 13240 for roomheaterslstoves and BS EN 12815 for cookers, which have been shown to give maximum hearth temperatures on the exposed surface not exceeding 100 C (and documented as such in the manufacturer’s instructions), the hearth should be of non-combustible board/sheet material and/or tiles with a combined thickness of at least 12 mm (see Figure 2) when placed on combustible material. Alternatively, the hearth should comprise the non-combustible hull structure (such as metal or concrete: see Figure 4b).
