1.3 ANTI-FREEZE PROTECTION.
Minimum temperature -3°C.
The boiler comes
standard with an antifreeze function that
activates the pump and burner when the water
temperature inside the boiler drops below 4°C.
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 drops
below -5° C, the appliance can freeze.
To prevent the risk of freezing follow the
instructions below:
- protect the central heating circuit from freez-
ing by inserting a quality antifreeze liquid into
this circuit, which is specifically adequate for
central heating systems and which is guaran-
teed by the manufacturer not to cause damage
to the heat exchanger or other components of
the boiler. The antifreeze liquid must not be
harmful to one’s health. The instructions of the
manufacturer of this liquid must be strictly fol-
lowed regarding the necessary percentage 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 or local regulations in
force).
Warning:
the excessive use of glycol could
jeopardise the proper functioning of the ap-
pliance.
The materials used for the central heating
circuit of Immergas boilers resist ethylene
and propylene glycol based antifreeze liq-
uids (if the mixtures are prepared perfectly).
For life and possible disposal, follow the sup-
plier’s instructions.
- Protect the domestic hot water circuit against
freezing by using an accessory supplied on
request (antifreeze kit) comprising an electric
heating element, the relevant cables and a
control thermostat (carefully read the instal-
lation instructions contained in the accessory
kit pack).
In these conditions the boiler is protected against
freezing to temperature of -15°C.
Boiler antifreeze protection (both -3°C and -15°C)
is thus ensured only if:
- the boiler is correctly connected to the gas and
electricity power supply circuits;
- the boiler is powered constantly;
- the boiler is not in stand-by (
);
- the boiler is not in anomaly conditions (parag.
2.6);
- the essential components of the boiler and/or
antifreeze kit are not faulty.
The 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 water
and heating connecting pipes must be insulated.
