4 Pipe connections
General
Pipe installation must be carried out in accordance with
current norms and directives.
Internal support bushes should be fitted when a plastic
or annealed copper pipe is used. The water heater must
be fitted with the requisite valves, such as a safety valve,
shut-off valve and non-return valve. An overflow pipe
should be routed from the safety valve to an appropri-
ate drain. The overflow pipe must be the same size as
the safety valve. Route the overflow pipe from the
safety valve enclosed along its entire length and ensure
that it is frost proof. The mouth of the overflow pipe
must be visible and not placed close to electrical com-
ponents.
