I pictured the plate in my pics.

Got little from furnace compare.
Do you have a good lookup link?

That is an optional hook-up.

I won't mention the dozen or more other issues I see. I'm sure you covered them...

Maybe not
Please list what you see.
There are many but not all in the pics here.
Yes lots of debris (clean filter) haha

Contacted a wholesaler and that is an option.

After looking at your photo the furnace ID Tag on the far right at the top part of the tag is cropped out but the second line does say "or direct vent"

Bob combustion air is not an issue as long as the room is not a confined space.
Is this in Chicago??

Jeff you are mis-interpreting
My concern as stated above was having a suction draw from that air intake directly from and within the closed cabinet itself.
There is no pvc extension at all to even the outside of the cabinet.

That is where my main concern is.

The water heater is a high eff model so I am not worried about back drafting.

Bob, it looks like you have a louvered front panel? A cat 1 would not have a sealed combustion chamber!

Ok then you are saying the intake being in the cabinet would have no (negative ) effect? Pun intended.

I wonder if it it obeys the 0ne square inch per 1,000 btu rule?

[Jeff Merritt]

As long as the room it is in meets the room volume L X W X H divided by 50 X 1000 = BTU

Bob, you have other issues, that damper is to close to he draft inducer,I am sure the MFG of the unit more than likely called for it to be farther/further away from the draft inducer blower, the way the unit is installed looks bad.
