(OP)
Why a 2" (6"wc) gas line to kitchen equipment comercial shell not be installed in a chase behaind the equipment? The sinior on the project said it is a no no, but did ot explain why?

A leak in an exposed area would not accumulate, mixing off and diluting rapidly. The oder would undoubtedly alert someone to its presense before large volumes accumulated and became excessively dangerous.

what about gas pipe in hung clg?
RE: Natural GAS low pressure in building
But since architects like to hide things like pipe and ductwork, we work with them.
Gas piping, at the pressure you are using, can usually be run above a ceiling or down a wall chase. If the above ceiling space is a plenum - you have to weld the piping and no valves are allowed.
Prior to occupying the building, the piping will have to be pressure tested for leaks. So once the piping passes the test, it is unlikely to leak - unless something moves or shifts.

Your senior probably said no to it because the low pressure piping normally use threads.
