Notes: A safety valve must be fitted in the
boiler flow pipework directly between the
boiler and the downstream isolating valve
(by the installer). If fitting a boiler altitude
gauge, a 3/8” BSP socket should be fitted by
the installer in the flow pipework adjacent to
the boiler to enable connection of the
altitude gauge pipework.
