1.4 OUTDOOR INSTALLATION.
The “Victrix 115 1 I” boiler has an IPX5D electric
insulation rating and can also be installed outdo-
ors, without additional protections.
Important:
all optional kits that can be potential-
ly connected to the boiler must be protected on
the basis of their electrical protection rating.
1.5 ANTI-FREEZE PROTECTION.
Minimum temperature -5°C.
The boiler comes
standard with an anti-freeze function that activa-
tes the pump and burner when the system water
temperature in the boiler falls below 3°C.
The 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 (Par.
- the boiler essential components are not faul-
ty.
In these conditions the boiler is protected against
freezing to an environmental 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 ignition block, the appliance
can freeze.
To prevent the risk of freezing follow the instruc-
tions below:
- Protect the central heating circuit from free-
zing by introducing a good quality anti-freeze
liquid (specifically for central heating systems),
carefully following the manufacturer’s instruc-
tions regarding the percentage necessary with
respect to the minimum temperature required
for preserving the system.
The materials the boilers are made from are
resistant to ethylene and propylene glycol-based
anti-freeze liquids.
For life and possible disposal, follow the supplier’s
instructions.
- Protect the condensate drain trap and P.C.B.
against freezing by using an accessory that is
supplied on request (anti-freeze kit) comprising
two electric resistances, the relevant cables and
a control thermostat (carefully read the instal-
lation instructions 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 efficient.
In these conditions the boiler is protected against
freezing to temperature of -15°C.
The warranty does not cover damage due to inter-
ruption of the electrical power supply and failure to
comply with that stated on the previous page.

1.7 CONNECTIONS.
Gas connection (Appliance category II
2H3P
).
Our boilers are built to function with methane
gas (G20) and L.P.G. The supply piping must be
the same or greater than the 1” G boiler fitting.
N.B.:
the gas supply pipe must be suitably di-
mensioned according to current regulations in
order to guarantee correct gas flow to the boiler
even in conditions of maximum generator output
and to guarantee appliance efficiency (technical
specifications). The coupling system must con-
form to standards.
Before connecting the gas line, carefully clean
inside all the fuel feed system pipes to remove any
residue that could impair boiler efficiency. Also
make sure the gas corresponds to that for which
the boiler is prepared (see boiler data-plate).
If different, the appliance must be converted
for operation with the other type of gas (see
converting appliance for other gas types). The
dynamic gas supply (methane or LPG) pressure
must also be checked according to the type used
in the boiler, which must be in compliance, as
insufficient levels can reduce generator output
and cause malfunctions.
Ensure correct connection to the gas cock.
A manual cut-off valve with quick closure mano-
euvre for 90° rotation and end run stops in the
all open or all closed positions must be installed
on the gas supply pipe in a visible and easily
reachable position outside the room where the
appliance is installed.
