*6 If the gas supply pressure is higher than the maximum permissible value, install a separate gas pressure governor upstream of the system.
*7 At 70 °C average boiler water temperature and cylinder storage temperature Tcyl = 60 °C.
The DHW performance factor NL depends on the cylinder storage temperature Tcyl.
Standard values: Tcyl = 60 °C → 1.0 × NL Tcyl = 55 °C → 0.75 × NL Tcyl = 50 °C → 0.55 × NL Tcyl = 45 °C → 0.3 × NL.
