(*) Only for I
2EK
: the appliance was configured for the appliance category K (I2K) and is suitable for the use of G and G+ distribution gases according to the specifications as
included in the NTA 8837:2012 Annex D with a Wobbe index of 43.46 – 45.3 MJ/m3 (dry, 0 °C, upper value) or 41.23 – 42.98 (dry, 15 °C, upper value). This appliance can
moreover be converted and/or be calibrated for the appliance category E (I2E). This therefore implies that the appliance “is suitable for G+ gas and H gas or is demonstrably
suitable for G+ gas and can demonstrably be made suitable for H gas” within the meaning of the “Dutch Decree of 10 May 2016 regarding amendment of the Dutch Gas
Appliances Decree and the Dutch Commodities (Administrative Fines) Act in connection with the changing composition of gas in the Netherlands as well as technical
amendment of some other decrees.
