1.3 ANTI-FREEZE PROTECTION.
Minimum temperature -5°C.
Minimum
temperature -5°C. The boiler is supplied with
an anti/freeze function as standard 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 in 'no ignition block' mode
(Par. 2.5);
- the boiler essential components are not faulty.
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 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:
- protects 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.
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 life 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 electricity
power supply circuits;
- the main switch is on;
- 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
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 heating
attachment pipes must be insulated.
