boilers leave the factory specifically prearranged
for G20 gas (methane) or G30/G31 (LPG). The G20 models
(methane) can be converted to function with G30/G31 (LPG)
using the "specific nozzle kit" (optional) provided by

– 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.
