Page 17: Gas Connections
Gas connections daia Novella RAI boilers must be connected to the methane or LPG gas supply in conformi- ty to applicable standards (figs. 3.6 and 3.7). Perform the following checks before making the connection. - Check that the boiler is compatible with the type of gas supply. - Page 18 DISABLING THE PRESSURE REGULATOR For the boiler to work with LPG fuel, the pres- sure regulator on the valve group needs to be disabled. To do so, proceed as follows: - Screw the pressure regulator screw (1) all the way in (fig. 3.9). - Unscrew the pressure measurement point screw (A) about 3 turns and connect up the pressure gauge (fig.
