> Insert a seal (1) in the cap nut (2).
> Screw the discharge pipe (3) onto the expansion relief
valve.
> Make the discharge line routing as short as possible and
sloping away from the boiler.
> Allow the line to terminate in such a way that nobody
can be injured and no cable or other electrical compo-
nents can be damaged if water or steam is ejected.
> Note that the end of the line must be visible.
> If the pipe cannot fall to a safe discharge point then the
Vaillant remote pressure relief valve mounting kit can be
used to provide a suitable way to achieve this.
> Ensure the discharge pipe work is installed, routed and
terminated correctly to minimise the risk of freezing up.
