General
Pipe installation must be carried out in accordance with
current norms and directives.
Internal support bushes should be fitted when a plastic
pipe or annealed copper pipe is used. The water heater
must be fitted with the requisite valves, such as a safety
valve, shut-off valve, non-return valve, and vacuum
valve. An overflow pipe must be routed from the safety
valve to a suitable drain. The size of the overflow pipe
must be the same as on the safety valve. Route the
overflow pipe from the safety valve enclosed along its
entire length and ensure that it is frost proof. The outlet
of the overflow pipe should be visible and clearly away
from any electrical components.
