6. If the pressure is too high (more than 5 mbar over) the appliance may be installed, but the gas supply company
should be contacted
7. Release the screw on the Burner Pressure test point on the gas valve and connect a manometer
8. Check that the measured pressure is as detailed in the Technical details
9. The measured value should be /- 10% of the described value. If this is not the case, please contact the
supplier.
Note: After checking the pressures and removing the manometers, the screws in the Pressure
Test points must be closed, and the system must be checked for gas-tightness.
