(1)  In the content of C1-C5 (sum) only Propane respectively Butane must be min. 95 g/(100 g) in Weight-%.

(2)  The components (sum): Hydrogen + N2 + O2 + CH4 is max. 0,2 g/(100 g) in Weight-%.

(3)  Exception for Butane: Additional supply pressure of 28-30 mbar for gas categories I3+ and II2H3+.

(4)  Depends on the pressure loss up to the appliance.

(5)  Depends on the gas network operators.

(6)  Depends on the operating pressure range.

(7)  Depends on the diameter of the pipeline.
