1.4 ANTIFREEZE PROTECTION.
Minimum temperature -15 ° C.
If the boiler is installed
in a place where the temperature drops below 0°C, 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 special-
ly suited for central heating systems and which is manufacturer
guaranteed not to cause damage to the heat exchanger or other
components of the boiler. Th e antifreeze liquid must not be
harmful to one's health. Th e instructions of the manufacturer
of this liquid must be followed scrupulously regarding the per-
centage 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 potential pollution
class of water 2 (EN 1717:2002).
Th e 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 life and possible disposal, follow the supplier's instructions.
- Protect the domestic hot water circuit against freezing by using
an accessory that is supplied on request (antifreeze kit) com-
prising two electric heating elements, the relevant wiring and a
control thermostat (carefully read the installation 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 -5°C and -15°C) is thus en-
sured only if:
- the boiler is correctly connected to gas and electricity power
supply circuits;
- the boiler is powered constantly;
- the boiler is not in “off” mode;
- the boiler is not in anomaly conditions (Par. 2.5);
- the essential components of the boiler and/or antifreeze kit are
not faulty.
Th 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.
Note: 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. Th 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.
