1.3 ANTIFREEZE PROTECTION.
Minimum temperature -5°C.
The boiler comes
standard with an anti-freeze function that ac-
tivates the pump and burner when the system
water temperature in the boiler falls below 4°C.
In these conditions the boiler is protected against
freezing to an ambient temperature of -5°C.
Minimum temperature -15°C.
In the event the
boiler is installed in a place where the tempera-
ture falls below -5°C, the appliance can freeze.
To prevent the risk of freezing follow the instruc-
tions 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 manu-
facturer guaranteed 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 followed
scrupulously regarding the percentage neces-
sary 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 withstand ethylene and
propylene glycol based antifreeze liquids (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 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 ac-
cessory kit pack).
In these conditions the boiler is protected against
freezing to temperature of -15°C.
Boiler antifreeze protection (both -5°C and -15°C)
is thus ensured only if:
- the boiler is correctly connected to gas and elec-
tricity power supply circuits;
- the boiler is powered constantly;
- the boiler is not in “off ” mode;
- the boiler is not in anomaly conditions (parag.
2.5);
- the essential components of the boiler and/or
antifreeze kit are not faulty.
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.
NOTE:
if the boiler is installed in places where
the temperature falls below 0°C the domestic
hot water and central heating attachment pipes
must be insulated.
The water in the storage tank unit is not protected
against freezing when the boiler is switched off.
