BOILER ROOM
The room where the boiler will be installed must comply with the requirements of the regulations in force
(thermal output up to 35 kW: UNI-CIG 7129, UNI-CIG 7131; thermal output above 35 kW: MD April 12
1996 of the Ministry of the Interior), with particular attention to compliance with the specifications relating to
the outwards opening of the same, so as to prevent serious damages to users and boiler failures.
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 UNI-CIG 7129 standard, considering the boiler output as shown in the
technical data tables.
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
(above 20 French degrees), suitably treated water must be used in the plant. Should it be necessary to use anti-
freeze, observe the percentages suggested by the Manufacturing firms based on minimum temperatures,
perfectly mixing the anti-freeze with the water.
For
ERA 31 B 130
if there is no possibility of expansion in the hot water circuit, a hot water expansion tank
