installation of pipework

It's important that all parts of the gas system installation pipework on your boat are accessible for routine examination, service and replacement. Pipework that can't be examined may hide damage.

To help LPG work efficiently, and to minimise the amount of pipework that is prone to damage, it's recommended that the installation pipework is run as short as possible, particularly between the cylinder(s) and the highest rated appliance(s). However, a longer run of pipe is acceptable if this reduces the likelihood of the pipe being accidentally damaged.

To protect pipework from potential mechanical damage which could cause it to leak, it must be run as high as possible within the hull, preferably at or above gunwhale level. Leaking pipework is easier to detect at this height since LPG sinks and may not be noticed if escaping from pipework situated at floor level. Fractured pipework or loose connections will leak. To ensure that the effects of vibration don't cause pipes to fracture, or the connections to loosen, the pipework must be rigidly secured with fixing clips spaced at approximately no more than 500mm (20ins) apart.

To reduce the possibility of abrasion to the pipework, it must be protected from damage where it penetrates bulkheads or walls, by the use of sleeves, grommets or bulkhead fittings. [7.16]
