prearranged for G20 gas or G30/G31. The G20 models can be
converted to function with G30/G31 using the "specific nozzle

– the pipes are clean
– the gas supply pipe is the same dimension as or greater than
that of the boiler fitting (G3/4") and with a load loss less than
or equal to that contemplated between the gas mains and the
boiler.
