Pipe installation

The water heater is only designed for upright installation.
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.
