The boiler can also be equipped with a full kit
for the production of domestic hot water .
This kit comprises:
- a plate heat exchanger
- a three-way diverter valve
- water fl ow switch
- pipes and unions for connection
The kit is preassembled by the manufacturer’s task is
to heat the domestic water from the water line of the
dwelling. In the moment in which there is request for
opening a hot water tap, the fl ow switch commands
the diverter valve to convey the hot water contained
inside of the boiler towards the plate heat exchanger.
In the case in which the heater is turned off and there
is demand for sanitary water, the heater after 30
seconds from the request, it automatically starts the
ignition process to heat the water inside the boiler
and then to heat the sanitary water.
Directions for use
If the installation of the boiler provides interaction
with another existing system complete with a heater
(gas boiler, gas boiler, oil boiler, etc..) consult qualifi ed
personnel who can then answer the compliance of
the system, as envisaged by the law in force.
Flushing the system
In accordance with the UNI-CTI 8065 is strongly
recommended to wash the entire system before
connecting it in order to get rid of residues and
deposits.
After fl ushing the system to protect it against
corrosion and deposits, it is recommended the use
of inhibitors.
Upstream from the stove, always install shutters so
as to disconnect it from the plumbing system should
it be necessary to move it, or when it requires routine
and/or special maintenance. Connect the boiler using
hoses so that the boiler is not too strictly connected
to the system, and to allow slight movement.
These are as helpful as the supply and return piping
system if the heating system is on a higher fl oor than
the boiler.
The exhaust pipe pressure is connected temporarily to
a carafe or a funnel to avoid, in case of overpressure,
that the water gush bathrooms and the structure and
the fl oor.
