5.12 - Hydraulic connection
for MYDENS -- B boiler
The “B” version of the boiler must be connected to a
indirect water heater with coil for the production of domestic
hot water (see also chapter 5.15).
To do this, fittings have been set-up for connection to the
indirect water heater. Operate as follows to prepare (refer
to figure 5.8):
1.- mount the reducer “A”;
2.- mount the wires “B” and “C”;
Make sure that every coupling has its own gasket
introduced
A = reducer fitting
B = supply to indirect water heater coil
C = return from indirect water heater coil

indirect water heater with coil
5.13 - Polyphosphates
softener (on request)
If the boiler is installed in a geographical area where
domestic water has hardness exceeding 25°F (250 mg/l), a
polyphosphates softener must be installed on the cold water
supply (see figure 5.9 detail “B”), in order to safeguard the
appliance from any lime scale deposits.
Proceed as follows for installation (refer to figure 5.9):
1.- connect the softener “B” to the cock “A”;
2.- mount the cock “A” to the boiler fitting;
3.- proceed with the installation of the cold water inlet pipe
into the fitting behind the softener “B”;
4.- before re-mounting the lower cover, it is necessary to
trim (only in the rear part), the entire part between walls
“C” and “D”, from the outer edge to the central slot, to
allow the softener “B” to be housed.
