Gas line

[deep]

I never put any gas line. What are things that i should keep in mind while putting a new line and its a commercial project?

What will be the pressure drop in a commericial building, its a restaurant?

TIA

As good as this site is for advice, no one here can outline how to do the job.

The b149 outlines installation practices as well how to pipe size. 

I'd start there .....
