The thermostove 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 flow 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 flow
switch commands the diverter valve to convey the
hot water contained inside of the thermostove
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
thermostove and then to heat the sanitary water.
Directions for use
If the installation of the thermostove provides
interaction with another existing system complete
with a heater (gas thermostove, gas thermostove,
oil thermostove, etc..) consult qualified personnel
who can then answer the compliance of the system,
as envisaged by the law in force.

EXCHANGER
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 flushing 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 stove using hoses so that the stove
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 floor
than the stove.
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 floor.
