1.8 HYDRAULIC CONNECTION
In order not to void the warranty of the primary heat
exchanger, before making the boiler connections, care-
fully clean the heating system (pipes, radiators, etc.)
with special pickling or de-scaling products to remove
any deposits that could compromise correct boiler ope-
ration.
3 bar safety valve
The drain of the safety valve must always be properly conveyed to a
draining funnel; consequently, in case of valve operation, the lea-
ked fluid will end up in the sewer system.
Condensate drain
To drain the condensate produced by the appliance, it is necessary
to connect to the drainage system by means of acid condensate re-
sistant 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 condensate can be cor-
rectly removed. After first ignition, check that the drain trap is fil-
led with condensate.
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 legisla-
tion in force.
A treatment of the heating and water system water is required, in
compliance with the technical standards in force, in order to pro-
tect 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 cou-
plings on the boiler template.
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. We also recommend using a
category 1, 2 or 3 heat transfer fluid (ex: water + glycol) in the boi-
ler's primary circuit (C.H. circuit), as defined in standard EN 1717.
To preserve the duration of appliance efficiency features,
in the presence of water whose features can lead to the
deposit of lime scale, installation of the “polyphosphate
dispenser” kit is recommended .
