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
