Water Circuit Installation - EdilKamin MILLA H 12 Installation, Use And Maintenance Handbook

PLUMBING CONNECTION
The plumbing connection depends on the type of
system.
However, there are some "common rules":
• The plumbing connection must be carried out by
qualified personnel who can issue documentation
declaring correct installation conforming to current
law in each country (for example, in Italy according
to Ministerial Decree 37/2008 and standard UNI
10412-2)
• The plumbing system must operate at a pressure
between 1 and 1.5-2 bar on a hot closed-vessel
circuit.
• Note: DO NOT install the stove in place of, for
example, a thermocooker installed with an open
vessel without an adequate expansion system
making it a closed vessel.
• The separation of the primary from the secondary
circuit is ideal and, in some countries, it is also
mandatory in case of the installation of a heating
plant (for example, in Italy, the reference is the
Circular from ISPESL, now INAIL, of April 2011).
This separation is easily carried out using KIT A2
from Edilkamin.
• The presence of a puffer (inertial storage tank) is
recommended but not mandatory. Its presence
has the advantage of freeing the stove from
"sudden" demands from the heating system and
allowing the integration of other heat sources. It
reduces consumption and increases the efficiency
of the system.
• The hot water exiting from the output of the stove
must be "directed" differently depending on the
objective (heating, radiators, exchanger, whether
or not there is a puffer, etc.)
• • The material used in the circuit must be suitable
to withstand any overheating.
• The discharge of the safety valve must be
accessible and visible. The discharge water must
be channelled into a vertical pipe using a funnel
with backflow air intakes, appropriately spaced
from the discharge point. The conveying pipe
must have the following characteristics:
• Must not originate more than 50 cm from the
discharge of the valve and must be positioned in
the same room where the KIT

INSTALLER
• Verify that the hydraulic system is correctly
installed and is equipped with an expansion tank
that is sufficiently large to guarantee safety. The
presence of a tank within the boiler-stove does
NOT guarantee appropriate protection from
thermal expansion occurring in the whole system.
• Therefore the installer must assess whether an
additional expansion tank is needed, depending on
the type of system installed.
Fill the system using the filling tap (it is recommended
not to exceed a pressure of 1,5 bar).
When filling, 'bleed' the pump and the relief tap.
PRESSURE GAUGE
Milla H has provided with an electronic reading system
for water pressure. Therefore, there is no analogue
pressure gauge. Water pressure is shown on the
display, on the bottom left (*) as indicated in the figure
below. Edilkamin proposes an analogue pressure
gauge as optional.
