NOTE:
The data provided in the following tables was obtained using 0.5 m concentric flue.
Gas flow rates refer to heating output below a temperature of 15°C and pressure of 1013 mbar.
Burner pressure values refer to use of gas at 15°C.
The number of revs for the fan on the display is expressed in revs / 50 (i.e. 1000 revs = 20).
