The diaphragm ventilation hole on the Nordic XP LPG reducer is a functional feature of the pressure regulation system and must not be plugged, sealed or covered.
This opening allows atmospheric pressure to reach the diaphragm, ensuring the correct operation of the pressure compensation system and stable gas pressure regulation.
During installation and maintenance, always make sure that the ventilation hole remains clean and unobstructed. Obstructing this opening may affect the proper operation and performance of the Nordic XP reducer.
For further information, please refer to the technical documentation of the Nordic XP reducer.
