Installer wants to run 1/2 inch flex stainless to a fireplace insert in 1 inch EMT conduit down the existing ash dump and through the basement wall where it would connect to the gas supply manifold. The flex and the EMT would be grounded. Any reason this should not be done. Can't find anything in the code preventing it but it seems odd.
No announcement yet.
