Anti-Freeze Protection - Immergas VICTRIX 26 2 I Instruction Booklet And Warning

1.3 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 4°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;
- the boiler is not off ("off " mode);
- the boiler is not in no ignition block (Par. 2.6);
- the boiler essential components are not faulty.
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
instructions below:
- protect the central heating circuit from freezing
by introducing a top quality anti-freeze liquid
into this circuit, which is not noxious to health.
The instructions of the manufacturer of this
liquid must be followed scrupulously regarding
the percentage necessary with respect to the
minimum temperature at which the system
must be kept. An aqueous solution must be
made with potential pollution class of water 2
(EN 1717:2002).
The materials used for the central heating circuit
of Immergas boilers resist ethylene and propylene
glycol based antifreeze liquids (if the mixtures are
prepared perfectly).
For duration and possible disposal, follow the
supplier's instructions.
- Protect the condensate drain trap and circuit
board against freezing by using an accessory
that is supplied on request (anti-freeze kit)
comprising two electric heating elements,
the relevant cables and a control thermostat
(carefully read the installation instructions
contained in the accessory kit pack).
Boiler anti-freeze protection is thus ensured only if:
- the boiler is correctly connected to gas and
electricity power supply circuits and powered;
- the anti-freezing 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
interruption of the electrical power supply and
failure to comply with that stated above.
N.B.: if the boiler is installed in places where the
temperature falls below 0°C the domestic water
and heating attachment pipes must be insulated.
1.4 ATTACHMENTS.
Gas connection (Appliance category II
Our boilers are designed to operate with methane
gas (G20) and LPG. Supply pipes must be the
same as or larger than the 3/4"G boiler fitting.
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, as insufficient levels can reduce
generator output and cause malfunctions.
Ensure correct gas cock connection. The gas
supply pipe must be suitably dimensioned
according to current regulations in order to
guarantee correct gas flow to the burner even
in conditions of maximum generator output
and to guarantee appliance efficiency (technical
specifications). The coupling system must
conform to standards.
Fuel gas quality. The appliance has been
designed to operate with gas free of impurities;
otherwise it is advisable to fit special filters
upstream from the appliance to restore the
purity of the gas.
Storage tanks (in case of supply from LPG
depot).
- New LPG storage tanks may contain residual
inert gases (nitrogen) 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 heating power of
the mixture delivered to the appliance, with
subsequent change in its performance.

Important: In order not to void the warranty
2H3B/P
before making the boiler connections, carefully
clean the heating system (pipes, radiators, etc.)
with special pickling or de-scaling products to
remove any deposits that could compromise
correct boiler operation.
In compliance with Standards in force it is
mandatory to treat the water in the heating
system chemically, in compliance with the
indications of the decree, in order to protect the
system and appliance from deposits of lime scale.
Water connections must be made in a rational
way using the couplings on the boiler template.
The boiler safety valve outlet must be connected
to a draining funnel. Otherwise, the manufacturer
declines any responsibility in case of flooding if
the drain valve cuts in.
Important: 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 . On the basis of the Standards
in force, it is mandatory to treat the supply water
with temporary water hardness over or equal to 25
French degrees in the central heating circuit and
over than or equal to 15 French degrees for DHW,
using conditioning chemicals for powers ≤ 100 kW
or with softeners for powers > 100 kW
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 having an
internal diameter 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
freezing of the liquid contained in it. Before
appliance start-up, ensure that the condensate
can be correctly removed. Also, comply with
national and local regulations on discharging
waste waters.
