proceed to adjust the maximum pressure setting. Any adjustment of the minimum pressure modifies the maximum
setting. The following adjustments, given their extreme sensitivity, should be carried out solely by company expert
personnel.

- Connect an appropriate manometer to the burner pressure test point.
- Disconnect the power supply wires leading to the "Modureg" coil "c".
- Disconnect the pressure balancing pipe "h"
- Remove the protection cap "d" fitted on top of the coil.
