It is not necessary to prepare any vent, but the arrangement for a correct air inlet and fume evacuation must be
strictly complied with (Refer to the following page).
CONNECTION TO THE GAS PLANT
The boiler must be connected to the gas plant according to the regulations in force. To determine the piping
diameters, refer to the tables of the UNICIG 7129 standard, considering the boiler output as shown in the
technical data tables (page 9).
CONNECTION TO THE WATER CIRCUIT
The boiler must be connected to the water circuit according to the regulations in force. In case of hard waters

freeze, observe the percentages suggested by the Manufacturing firms based on minimum temperatures,
perfectly mixing the anti-freeze with the water.
