Depends how far from the gas metre.

Maybe but why does it state in the installation manual 22mm, no mention of distance from meter, a metre is a distance of measurement I would have thought a Plumber would have known the difference.:p

You need to understand how gas supply pipes are sized according to the demand. Although the direct connection to the boiler will be 22mm, the route back to the meter may include larger pipework, depending on other connections to the supply. Your qualified installer will know all this.
