N.B. - The gas pressures at the burner and gas flows 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 figures 4 and 5).
During  domestic hot water production, gas pressures to the burner must correspond to the maximum output given
in table for the type  of gas.
Gas pressure must be adjusted during maximum draw-off of domestic hot water.
• Maximum working temperature for central heating flow: 85
°
C
• Maximum  temperature of  domestic hot water: 55
°
C, adjustable between 40
°
C and 55
°
C.
• Minimuum domestic cold water pressure required for 95% heat input:
- Flow restrictor fitted (standard) - 1,2 bar;
- Flow restrictor removed - 0,5 bar
