1.7 HYDRAULIC CONNECTION.

In order not to void the condensation module war-
ranty before making the boiler connections, carefully
clean the heating system (pipes, radiators, etc.) with
special pickling or descaling products to remove
any deposits that could compromise correct boiler
operation.
A treatment of the heating and water system water is required,
in compliance with the technical standards in force, in order to
protect the system and the appliance from deposits (e.g. scale),
slurry or other hazardous deposits.
Water connections must be made in a rational way using the
couplings on the boiler template.
ATTENTION:
the manufacturer declines all liability
in the event of damage caused by the
installation of an automatic filling system.
In order to meet the system requirements established by EN 1717
in terms of pollution of drinking water, we recommend installing
the IMMERGAS anti-backflow kit to be used upstream of the cold
water inlet connection of the boiler.
To preserve the duration of appliance efficiency fea-
tures, in the presence of water whose features can
lead to the deposit of lime scale, installation of the
"polyphosphate dispenser" kit is recommended .

ATTENTION:
if the boiler is used for room central
heating only without connecting an ex-
ternal storage tank, you are required to install a
special bypass pipe (supplied in the document
bag) to prevent damage to the said boiler.
3 bar safety valve.
The boiler safety valve outlet must be connected to a draining
funnel. Otherwise, the manufacturer declines any responsibility
in case of flooding if the drain valve cuts in.
Condensate drain.
To drain the condensate produced by the appliance, it is necessary
to connect to the drainage system by means of acid condensate
resistant pipes, with an internal Ø of at least 13 mm. The system
connecting the appliance to the drainage system must be carried
out in such a way as to prevent occlusion and freezing of the liquid
contained in it. Before appliance ignition, ensure that the con-
densate can be correctly removed. After first ignition, check that
the drain trap is filled with condensate (Para. 1.23). Also, comply
with national and local regulations on discharging waste waters.
In the event condensate is not discharged into the wastewater
drainage system, a condensate neutraliser must be installed to
ensure compliance with the parameters established by the legis-
lation in force.
