N.B. - The gas pressures at the burner and gas fl ows during the central heating phase given in the table refer
to nominal boiler output. To reduce this output (where necessary), gas pressure must be reduced until the
required output level is reached (see fi gures 4 and 5).
• Maximum working temperature for central heating fl ow: 85°C
