Pipe installation must be carried out in accordance
with current norms and directives.
When the circulation pump is running, the flow in the
radiator circuit must not be completely stopped. In oth-
er words, in a system where the radiator flow might
stop because all thermostat valves are closed, there
must be a bypass valve to protect the circulation
pump.
The total volume is 240 litres, with 170 litres in the
water heater and 70 litres in the double-jacket space.
The pressure vessel in the VVM 240 is approved for
max 9.0 bar (0.9 MPa) in the water heater and 2.5 bar
(0.25 MPa) in the double jacket space.
An overflow pipe should be routed from the overflow
cup (99) to an appropriate drain. The diameter of the
overflow pipe should be the same as the waster water
pipe, Ø 32 (98) and should be routed downwards to
prevent water pockets and to be frost proof. The outlet
of the overflow pipe should be visible. See applicable
standards.
General
NOTE!
The pipe work must be flushed before
the electric boiler is connected, so that
any contaminants do not damage the
components parts.
