1.6 OUTDOOR INSTALLATION.
e boiler has an IPX5D electric insulation rating and can also be
installed outdoors, without additional protections.
ATTENTION:
all optional kits that can be potentially con-
nected to the boiler must be protected on
the basis of their electrical protection rating.
1.7 ANTIFREEZE PROTECTION.
Minimum temperature -5°C. The boiler comes
standard with an anti-freeze function that activates the
pump and burner when the system water temperature
in the boiler falls below 5°C. e anti-freeze function
is only guaranteed if:
- the boiler is correctly connected to gas and electricity power
supply circuits;
- the boiler is powered constantly;
- Main switch is inserted;
- the boiler is not in no ignition block;
- the boiler essential components are not faulty.
In these conditions the boiler is protected against freezing to an
ambient temperature of -5°C.
Minimum temperature -15°C. If the boiler is installed in a
place where the temperature falls below -5°C and in the event
there is no gas (or the boiler goes into failed ignition block),
the appliance can freeze.
To prevent the risk of freezing follow the instructions below:
- Protect the central heating circuit from freezing by inserting
a good-quality antifreeze liquid into this circuit, which is
specially suited for central heating systems and which is
manufacturer guaranteed not to cause damage to the heat
exchanger or other components of the boiler. e antifreeze
liquid must not be harmful to one’s health. e instructions
of the manufacturer of this liquid must be followed scrupu-
lously regarding the percentage necessary with respect to the
minimum temperature at which the system must be kept.
N.B.: the excessive use of glycol could jeopardise the proper
functioning of the appliance.
An aqueous solution must be made with a potential water
pollution class 2 (EN 1717:2002 or local regulations in force).
e materials used for the central heating circuit of Immergas
boilers withstand ethylene and propylene glycol based anti-
freeze liquids (if the mixtures are prepared perfectly).
For life and possible disposal, follow the supplier’s instructions.
- Protect the condensate drain trap and relative drain against
freezing by using an accessory supplied on request (anti-freeze
kit) comprising two electric resistances, the relevant cables
and a control thermostat (carefully read the installation in-
structions contained in the accessory kit pack).
Boiler anti-freeze protection is thus ensured only if:
- the boiler is correctly connected to electricity power supply circuits;
- main switch is inserted;
- the anti-freeze kit components are ecient.
In these conditions the boiler is protected against freezing to
temperature of -15°C.
e warranty does not cover damage due to interruption of the
electrical power supply and failure to comply with that stated
on the previous page.
N.B.: if the boiler is installed in places where the temperature
falls below 0°C the domestic hot water and central heating
attachment pipes and the condensate drain pipe must be
insulated.
Note: the antifreeze systems described in this chapter are
only to protect the boiler. e presence of these functions
and devices does not exclude the possibility of parts of the
system or domestic hot water circuit outside the boiler from
freezing.
1.8 GAS CONNECTION.
Our boilers are designed to operate with with natural gas (G20)
and L.P.G. Supply pipes must be the same as or larger than the
boiler tting Victrix Pro 80 2ErP, 1“ Victrix Pro 100-120 2ErP.
ATTENTION:
before connecting the gas line, carefully
clean inside all the fuel feed system pipes
to remove any residue that could impair boiler
eciency. Also make sure the gas corresponds
to that for which the boiler is prepared (see
boiler data-plate). If dierent, the appliance
must be converted for operation with the other
type of gas (see converting appliance for other
gas types). e dynamic gas supply (methane
or L.P.G.) pressure must also be checked ac-
cording to the type used in the boiler, which
must comply with EN 437 and relative attach-
ments and with the local technical regulations
in force, as insucient levels can reduce gen-
erator output and cause malfunctions.
Ensure correct gas cock connection.
According to local regulations in force,
make sure that a gas cock is installed
upstream of each connection between
the appliance and the gas system. is cock,
if supplied by the appliance’s manufacturer,
can be directly connected to the appliance
(i.e. downstream from the pipes connecting
the system to the appliance), according to the
manufacturer’s instructions.
e gas supply pipe must be suitably dimensioned according to
current regulations in order to guarantee correct gas ow to the
burner even in conditions of maximum generator output and
to guarantee appliance eciency (technical specications). e
connection to the gas supply must conform to standards.
