Pipe length to dia.

[Bylough]

Hi! Is 10mtr. length of 15mm dia. pipe -back to the meter- ok for an average (normal) sized gas fire (on the hearth). Or is 22mm a better option?
Thanks for any guidance- (I am only laying the pipe ready for jointing by a plumber).
Apologies to the regulators and others for asking this question previously.
Thanks again.
(I come up from under the floor only occasionally!)

15mm is fine.

Many thanks, chrishutt, for your prompt and helpful reply.
Now I can get on with the job -'the pipes, the pipes' (are calling me)!
Regards.
