Pressure (Safety) Relief Valve
In accordance with the prevailing British Standard 5440/6644, the installer shall install as suitably sized
Pressure (Safety) Relief Valve.
The location of this valve is important with respect to the applied pressure of the units circulation pump,
it is therefore recommended to locate the Pressure (Safety) Relief Valve on the return pipe immediately
adjacent to the heat generator; furthermore, there must not be any means of isolation between the unit
and the Pressure (Safety) Relief Valve.
To assist with the correct positioning of the pressure relief valve hydraulic connector kits are available as
an optional extra.
