Hey folks, ran into this on an inspection today. I believe the Tee previously was used to tie in a conventional furnace. It was later replaced with a high efficiency model that vents through PVC. Is it ok to leave the Tee fitting with a cap?

Yes.
Was there any evidence that the water heater flue gases were cooling before fully exhausted?

That’s why they make caps.

I see that at least once a week, and until I installed a WH with a power vent, I had that same set up in my house.
