Hydraulic Connection - Immergas Victrix Tera 28 1 Instructions And Warnings

Storage tanks (in case of supply from LPG depot).
- New LPG storage tanks may contain residual inert gases (nitro-
gen) that degrade the mixture delivered to the appliance casing
functioning anomalies.
- Due to the composition of the LPG mixture, layering of the
mixture components may occur during the period of storage in
the tanks. This can cause a variation in the calorific value of the
mixture delivered to the appliance, with subsequent change in
its performance.

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. In order not to void the heat
exchanger warranty, you are required to comply with what has
been prescribed in (Par. 1.24).
Hydraulic 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. We also recommend using a
category 1, 2 or 3 heat transfer fluid (ex: water + glycol) in the boil-
er's primary circuit (CH circuit), as defined in standard EN 1717.
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 .
3 bar safety valve.
Safety valve (Part. 3 Fig. 7) discharge must always be conveyed
through a draining funnel. Consequently, in the event of valve
intervention, the discharged liquid 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
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. 1.26). 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.
