Can gas tubing be concealed in a conversion vendor unit or medical unit?

(1) Tubing must not be run inside walls, floors, partitions, or roofs.
(2) If tubing passes through walls, floors, partitions, roofs, or similar installations, the tubing must be protected by the use of weather resistant grommets that snugly fit both the tubing and the hole through which the tubing passes.
