Burner adjustment

(Prohibited in Belgium).

With the burner operating at full power, the CO2 must be in the range 8.8 to 9.2 % (natural gas) or 10.5 to 10.6 % (propane).

If necessary, adjust the CO2 by turning the screw clockwise to reduce it and counter-clockwise to increase it. (see photo opposite).
