Example (when using natural gas G20)
During the measurement at maximum output the value of O2(H) was 4.1 %.
The setting for O2(L) at minimum output will then be 5.05 ± 0,2 %
1. Replace the cap A of the adjustment screw B for protection
2. Repeat the measurement at maximum and minimum output (§ 1.2.1 en § 1..2.2)
to ensure the correct operation of the boiler.
