What is the inspector's most likely finding regarding this installation?
- AThe installation is acceptable, as long as the connector is properly rated.
- BThe connector must be replaced with rigid black steel piping.
- COnly a portion of the connector can be concealed, not the entire length.

Show answer & explanationAnswer & explanation
Correct answer: D. Flexible gas appliance connectors are not permitted to be concealed within walls.
Flexible gas appliance connectors are designed for easy connection and disconnection of appliances, but they are not permitted to be concealed within walls, floors, or partitions. This is a critical safety measure to ensure accessibility for inspection, maintenance, and to prevent damage in concealed spaces.
Why the other options are wrong
- A. Even if rated, concealment is generally prohibited for flexible appliance connectors.
- B. While rigid piping is permitted in walls, the issue here is the concealment of a *flexible appliance connector*, not the general use of rigid pipe.
- C. No portion of a flexible appliance connector is permitted to be concealed within structural elements.

- Applies to all flexible appliance connectors.
Memory trick: Connectors Must Be Clearly Seen.
