(1)  Only CO2.

(2)  The minimum and maximum pressure values reported constitute the technically permissible thresholds (UNI 11323: 2016), for limited periods of time, taking into account any physiological pressure trends in gas distribution networks.

(3)  Values provided in accordance with the English version of the text of Regulation (EU) 2016/426 on appliances burning gaseous fuels.
