“Ambient Anti-Frost” Function
If the building relevant to the boiler remains unoccupied during cold weather periods, you should con -
sider the chance to extend the protection against freezing to the whole heating system (and therefore
to the rooms) besides the boiler itself. Also for this function, the boiler must be receiving gas and elec-
tricity, and the system pressure must be correct.
f
if the Remote Control (original, optional kit) is installed, the anti-freeze function is automatically
performed by switching the boiler in stand-by mode by means of the suitable button on the control
itself. The boiler, the DHW storage, and the rooms will be kept at a minimum temperature that avoids
the freezing of the liquids in them;
f
if a common room thermostat or chronothermostat is installed, featuring* the “Ambient Anti-
Frost” function, and you want to use it, it'is necessary to leave the boiler in Winter mode and
NOT in stand-by or in Summer mode) to allow the boiler to activate when the room tempera-
ture sensor requires the heating. To minimize the gas consumption, it's also advisable to lower the
storage temperature by turning the DHW temperature knob to the minimum, on , otherwise
the water in the storage will be uselessly kept hot.
* failing this function, you can anyway set the room temperature a few degrees above zero, e.g. +5°C (if it's a chronothermostat,
remember to set it to manual mode).
The “Ambient Anti-Frost” function does not protect the sanitary circuit outside the boiler and,
especially, in areas where the heating system doesn’t reach. For this reason, we recommend
that you empty the cold and hot sanitary system, if they were at risk of freezing.
Installation
Law and regulation prescriptions for the installer
Note for the translator/writer: Place in this paragraph all the recommendations relevant to the compli-
ance with laws in the destination nation/country (if any). As an example (from Italian regulation):
Characteristics of the room: as this boiler has an heat output lower than 35 kW (about 30000 Kcal/h),
it is not required to install the appliance in a dedicated room, provided that the room complies with
the regulation in force and that all installation rules assuring a safe and regular gas boiler operation,
are strictly respected.
Permanent ventilation of the installation room is mandatory and extremely important when
a boiler with air draught from the installation room (B… appliance type) is installed. Ventilation
must be made and sized in compliance with Laws and Rules in force.
Instructing the user: at the end of the installation, the installer must:
• explain the operation of the boiler and its safety devices to the user;
• give this user this booklet and the documentation within his/her competence, duly filled in where
required.
