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