gas/air ratio is maintained over the total range of the boiler mo-
dulation, and that constant CO

values are achieved.
For optimum utilisation condensing boilers should be operated at
a low return temperature. However the PARAMOUNT two will also
work at designed temperatures of 70/50°C. In the condensing
mode as the return temperature is below the dew point (dew point
is 53°C at 8.5 % CO

).
They fulfil EN 483 and EN 677, Type C. Installation types B23, B33,
C13x, C33x, C43x, C63x. Emission value group G 61.
