Plumbing installation of the boiler to the heating network
The water supply to the heating network
and the domestic water should be derived
from the water supply network.
The presence of calcium and salts in water
can cause premature corrosion in the
boiler and other problems.
Ensure to keep hot the boiler pipes.
The pipes should not be exposed to frost.
The pipes should be insulated with an
insulation thickness of more than 25 mm
in order to be protected against frost
(50mm in cold areas).
In case of frost occurring on the plumbing
of the heating network, the antifreeze
protection available within the unit, in the
area controlled by the thermostat will not
function adequately.
In order to select the size of the expansion
tank estimate that for every thousand
calories of boiler is required at least a liter
in the tank.
The expansion tank and the safety valve
shall be checked regularly to ensure good
operation and long lifetime of the boiler.
If the safety valve opens often then it is
due to increase of the pressure of the
network.
Check the automatic water filler of the
heating network and the pressure in the
expansion tank and fill with air (1 bar) if it
is deemed necessary.
Connect the safety valve outlet with a tube
in the drainage to drain of the water.

The backflow valve is positioned to prevent the natural flow of
water to the radiators when we ask for hot domestic water during
the summer months.
