New Boiler

[f49h]

Hi Guys,
I have just installed new pipework for my new central heating system.
(22mm supply / return, 15mm to rads)
The next problem is which boiler.
I have a 2 story end terrace house, double glazed, 9 radiators.
I want to change my shower to be fed of the new combi boiler. and at a later date install a bath
I was thinking of a Vokera Linea730 or 735.
The gas supply to the old boiler is 15mm.
Would the boiler size be ok and will I have to get the corgi fitter to upgrade the gas pipe to 22mm
Cheers

For a start the gas supply will have to be in at least 22 mm if the distance to the meter is no more than about 5 m, perhaps 28 mm if its further!
