Boiler inactivity The effects of the periods of inactivity can be relevant in particular situations such as in flats used only for some months per year, most of all in cold places. The user will have to decide to put the boiler in the SAFETY SHUT OFF state disconnecting all the sup- plies, or to leave it on OFF mode (but electrically supplied) in order to let the Anti Frost Function work. -
Page 17: Ambient Anti-Frost" Function
ATTENTION: the anti-frost protections cannot intervene in the absence of electricity. If you an- ticipate this possibility, we recommend you add a good brand of anti-freeze to the heating sys- tem, following the producer’s instructions. We recommend to ask directly the installer/technician about the type of antifreeze product put in the heating system during installation. -

Page 22: Siphon Overflow Drain
Siphon overflow drain The boiler’s siphon is equipped with a supplementary safety discharge SCD that protects the burner in the very situation in which the condense does not from correctly from the drain pipe downstream from the siphon. Since this is easily accessible from the rear of the boiler, evaluate the opportunity to use it or not before installing the boiler, by connecting to it a section of flexible hose 1 suitable for condense. -

Before inserting the flue outlet pipe it’s therefore very important to correctly place the gasket on its seating as indicated in the figure. - Page 28 In case you foreseen to discharge the combustion products through a chimney (for single user) or a common flue (for multiple users) the part of the evacuation system (the chimney or the flue) to which the outlet duct of the condensing boilers is con- nected, must be declared suitable for this purpose by its producer.

Page 39: Combustion Test And Adjustment
Combustion test and adjustment Before checking the combustion, clean the burner and the exchanger as described in the para- graph "Combustion group cleaning" on page 35 (except for the case of first ignition). To check and adjust the boiler you need a flue analyser, correctly calibrated (in the condensing boiler, the precision and the correctness of the measures is particularly important). -

Addendum Outdoor Sensor Kit Installation and setting The Outdoor Sensor manages automatically the CH flow temperature** as a function of the outdoor temperature, thus avoiding the user to adjust it manually. This function is also named "shifting tempera- ture". that's the temperature of the heating elements. Don't mistake it with the room temperature (managed by the room thermo- stat or by the Remote Control, but not by the boiler) that doesn't depend on the first one. -
Page 60: Remote Control Kit
Remote Control Kit This remote control is more than a simple room thermostat. Thanks to this, it is possible to manage the boiler in all its set- tings like DHW and CH temperature adjustment, boiler reset in case of boiler block, and of course it works as a room thermo- stat both in manual and weekly program mode. - Page 61 Notes Green Heating Technology...
