Furnace venting, open

c Capture
Central NJ, 1969 build, Slab on grade:
My understanding is that an induced fan furnace should not have such an open vent connector/draft hood. Can you confirm this and can you identify the name of this vent so that I can do some more research into it? The numbers printed on it didn’t help me.
I looked up the Carrier installation manual, snip attached, but it wasn’t much help to me.
This unit did have approvals and appeared to have a spill switch.
Thank you very much.

That needs a qualified HVAC professional badly. :flushed:

Thank you Larry!

Do any of you put something into the report to forestall the obvious question about how something could be wrong when it has the local officials approval stickers on it?
