Minimum temperature -15°C
In the previously listed conditions ad with the addition of the antifreeze kit, the appliance is protected against freezing up to a
temperature of -15°C.
Protect the domestic hot water circuit (when paired with a storage tank unit) against freezing by using an accessory that is supplied on
request (antifreeze kit) comprising an electric resistance, the relevant wiring and a control thermostat (carefully read and follow the in-
stallation instructions contained in the accessory kit pack).
Appliance antifreeze protection is thus only ensured if:
- the appliance is correctly connected to gas and electricity power supply circuits;
- the appliance is powered constantly;
- the appliance is not in "off" mode.
- the appliance is not in anomaly conditions (Parag. 2.5);
- the appliance essential components 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 pre-
vious pages.
If the appliance is installed in places where the temperature falls below -5°C the domestic hot water and central heating attach-
ment pipes and the condensate drain pipe must be insulated.
The antifreeze systems described in this chapter are only to protect the appliance; the presence of these functions and devices
does not exclude the possibility of parts of the system or domestic hot water circuit outside the appliance from freezing.
