If you charge the central heating system with hard water, this may cause
blockage of the heat exchanger.
Mains supply water should not exceed 15° French hardness value. To
prevent any corrosion, pH value of the water should be between 8,2
-9,5,conductivityshouldbelessthan30μS/cm,andoxygencontent
should be less than 0,1 gr/m³.
Hot water circuit does not need a pressure relief valve. On the other
hand, pressure should not exceed 6 bars. In case of doubt, a pressure
regulatorshouldbetted.Consultyourinstalleronthisissue.

1.4 ECONOMY MEASURES
Your boiler is designed and manufactured to minimize the gas consump-
tion.
For further saving below are recommended:
• Yourboilerisadjustedto20.726kcal/hourofoutputcapacity.Down
rating of the heating capacity will save in houses where heating re-
quirement is less. Consult the authorized service for adjustment.
• Use of thermostatic radiator valves or ow balance of radiators
brings additional saving due to homogenous heat distribution over
the house.
