e internal gas supply system must be built in compliance with
the provisions and regulations and all legislation in force, and
any other reference on good technique. If the generator does not
exceed the maximum nominal heat input of 35 kW (Victrix Pro
35 2 ErP in individual installation) simply follow the provisions
set forth in the technical regulation in force
Install a manual cut-o valve with quick closure manoeuvre for 90°
rotation and end run stops in the all open or all closed positions
on the gas supply pipe in a visible and easily reachable position
outside the room where the appliance is installed.
ATTENTION:
the appliance has been designed to op-
erate with combustible gas free of im-
purities; otherwise it is advisable to t special
lters upstream of the appliance to restore the
purity of the fuel.
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 causing
problems with boiler operation.
- Due to the composition of the LPG mixture, layering of the mixture
components may occur during the period of storage in the tanks.
is can cause a variation in the heating power of the mixture de-
livered to the appliance, with subsequent change in its performance.
1.9 HYDRAULIC CONNECTION.
In order not to void the condensation module warranty,
before making the boiler connections, carefully wash
the CH system (pipes, radiators, etc.) with special pick-
ling 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.
Chemical conditioning treatment is always required in relation
to the quality of the water used in the water systems for winter
heating, with or without domestic hot water production, still
following the provisions of the law in force. System water swe-
etening treatment required for systems with furnaces with heat
output greater than 100 kW and supply water with hardness
greater than 15 french degrees. Refer to the laws in force for the
aforementioned treatments.
ATTENTION:
the manufacturer is not liable in case of
damage caused by the absence of heat
and water systems water treatment.
It is recommended to prepare a lter in the system
to collect and separate any impurities present in the
system (slurry remover lter).
In order to avoid deposits, scaling and corrosion in the central
heating system, the provisions set forth in the technical regulation
in force on water treatment in heating systems for civil use must
be respected.

cable
Water connections must be made in a rational way using the cou-
plings on the boiler template. e discharge of the boiler safety
valve must be connected to a tundish and then the waste should
be connected to the sewer. Otherwise, the manufacturer declines
any responsibility in case of ooding if the drain valve cuts in.
ATTENTION:
the manufacturer declines all liability in
the event of damage caused by the inclu-
sion of automatic lling that is not its own brand.
In order to meet the system requirements established by EN
1717 and in observance of local technical regulations in force
on the pollution of drinking water, we recommend installing an
anti-backow kit to be used upstream of the cold water inlet con-
nection of the boiler. We also recommend using category 2 heat
transfer uid (ex: water + glycol) in the boiler’s primary circuit
(C.H. circuit), as dened in standard EN 1717.
To preserve the duration of appliance eciency fe-
atures, we recommend the installation of a suitable
device for water treatment in presence of water whose
characteristics can lead to the deposit of lime scale.
Condensate drain.
Condensate must be drained according to the laws in force.
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. e system
connecting the appliance to the drainage system must be carried
out in such a way as to prevent freezing of the liquid contained in
it. Before appliance start-up, make sure that the condensate can
be correctly removed, in accordance to the provisions of the laws
in force; aer rst ignition, check that the drain trap is lled with
condensate (para. 1.22). 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 legi-
slation in force.
