8.3 General directions for the heating installation
Caution! Before connecting the central heating BOILER carefully wash the entire
heating installation! In this way, you eliminate from the pipes various debris such
as welding splashes, scoria, grummet, putty, dirt or similar. Otherwise, these
substances can form deposits in the heating switcher and can cause damage
or malfunctioning.
The equipment is provided with a 7l capacity and 1 bar loading pressure expansion vessel.
Before installing the equipment, check whether this volume is sufficient. If not, an
additional expansion vessel must be installed on the aspiration side of the pump.
Caution!
Check the pressure inside the expansion vessel before commissioning.
Pressure inside the expansion vessel must be 0.8÷1bar.

General directions for the hot water circuit
Caution!
It is obligatory to install an impurity filter on the return of the thermal circuit
installation!
When installing connecting pipes it is essential for these not to be tensed to
avoid creating areas of leakage!
Maximum working pressure allowed is 3bar.
Recommended working pressure is 1.5 barr!
When designing the heating installation will take into account the hydraulic characteristics
of the pump fitted this model central ! See indications cap.11.3.
Caution! It is forbidden to use the central heating BOILER without thermal agent or
partilally filled – danger of explosion! It is forbidden to use the central heating
BOILER if it is not completely aired!
Central heating BOILERS

GN
natural gas The gas connecting pipe
.
is made of stainless steel with an interior diameter of 12.4 mm. The gas input pipe must not
have a diameter smaller than that of the gas connecting pipe of the central heating
BOILER. The fuel input must be done according to applicable legal stipulations.
Connect the central heating BOILER to the hot water installation.
It is obligatory to install filters to de-harden the water and a mechanical impurity
filter on the cold water input connecting pipe!
Caution! When installing connecting pipes it is essential for these not to be tensed
to avoid creating areas of leakage!
The apparition of pressure shocks (input pressures higher than 3-4 bars in addition to
symoultaneously activating quick closing taps) can affect the components of the hydraulic
circuit inside the central heating BOILER. We recommend the installation of a pressure
regulator adjusted to 3-4 bars!
Damage caused by the apparition of pressure shocks or by the use of higher pressure than
recommended on the cold water input circuit is not covered by the warranty!
