Natural gas piping in plenums
Natural gas piping in plenums
(OP)
Occasionally we have to run natural gas piping above the ceiling in return air plenums. This has come up recently in a couple restaurants. Can't find a code limitation. I recall in the past using welded pipe in this application. Does anyone have any thoughts? Thanks.

A.6.2.5 It is the intent that gas piping, shutoff valves required by this code, and regulators be allowed to be installed in accessible portions of plenums, accessible ducts used to supply combustion and ventilation air in accordance with Section 5.3, and accessible spaces between a fixed ceiling and dropped ceiling.
