Single wall into B vent question

Mid 80’s Lennox gas furnace. Two foot long section of single wall galvanized stove pipe shoved into the next piece of “B” vent. No locking tabs, no screws. Seems wrong to me. Anyone else?

I can’t see a thing from here, but I would advise that you call it as you see it. You don’t need a law, code or rule to talk about issues in a home inspection. If you can rationalize a good reason for an issue to be considered, voice your opinion.

Just don’t cause additional expense to anyone by having some alleged professional evaluate what you have to say. State your business, and work with your client. It doesnt have to be fixed, just brought to your clients attention.
