CSST appliance penetration (non-moveable)

Can CSST penetrate an appliance cabinet if properly sleeved/protected with a bushing/grommet? I’m getting conflicting info all over the place. What do you say and/or how do you report? Thanks in advance.

The manufacturers requirements are clear. Is that the brand of the CSST you found? There are few and there is a brand that allows penetration through the metallic cabinet.

With a grommet.
