USING AN EXPANSION KIT
The Europrisma 10 and 15 litr e capacity units can be installed in one of
two ways. The following guidelines ar e designed to help select the
correct items prior to installation.
Current Water Regulations and
Byelaws per mit unvented water
heaters with capacity of 15 litr es or
less to accommodate the expansion
of water that occurs during the
heating cycle in the system pipe
work. To achieve this the pipe work
between the last cold water draw of f
and the water heater must be of
sufficient volume to accommodate
the expansion.
If it is not possible to accommodate
the expansion in the system pipe
work, it is then necessar y to use an
expansion vessel and non-r eturn
valve (Kit A). If the mains water
pressur e may exceed 3.5 bar a
pressur e reducing valve (Kit B)
should also be installed. The
discharge from relief valves must be
made in a safe and conspicuous
manner; ther efore a tundish (Kit C) is
available for 10 and 15 litr e units
if required.
The Europrisma EP 30 R is cover ed by the Building Regulations and it is not possible to accommodate the expansion
water within the system pipework. Expansion contr ols must be installed. The EP 30 R is supplied with a tundish as
standard.
