The provisions of this section of Part 8 in the 2002 BSS Standards are mandatory for non-private boats where applicable.

Some appliances are just not suitable for use on boats, e.g. where they generate too much heat in a confined space or where they are heavy and unstable. If surfaces next to an appliance get overheated there is a danger that they could catch fire. To reduce the risk of this happening you must make sure that all appliances are suitable for use on your boat, situated in sufficient space and are properly installed in line with the manufacturer's instructions for installation on boats.

Gas appliances can be connected with flexible pipes if the appliance is portable (e.g. can be moved for cleaning purposes). The hose needs to be fitted with an isolating tap on the feed side of the hose (to each appliance). Even though it is connected via a hose, the appliance must still be secured. Another situation where a hose is permitted is if the final connection to, say, a built-in hob unit over an oven unit, could not be made with fixed pipework because of difficulty accessing the joints. [8.3]

The installation instructions for appliances which were already in place before 3 January 2000 may not be available. Where woodwork and all other combustible materials, including curtains, are close to these appliances they are acceptable provided there is no damage evident. In general, woodwork and combustible materials which are not inherently flame retardant must be suitably insulated, protected against excessive heat or treated with a durable flame retardant.

To prevent damage to gas pipes and flue joints you must make sure that all appliances are secured against accidental movement and connected in such a way that undue stress on pipework or fittings is prevented.

Petrol vapour mixed with air is very explosive and steps must be taken to reduce the risk of it becoming ignited by an appliance burner. LPG and fuel oil appliances therefore must not be installed in petrol engine spaces. [8.3]
