Re: WATER HEATER AND BOILER VENT PIPES
unlisted horizontal draft hood. That and the single walled connector should not be there.
Listed and approved draft hoods only and B-vent only in crawl space.
Condition of chimney?
clean out?
Liner?
Clearances to combustibles off that single walled pipe?
Support?
Screws?
Keep the fire in the fireplace.

If this is on the water vent pipe, it will act as a second draft hood, and double draft hoods are not permitted. It dilutes exhaust gases and might cause spillage into the crawlspace.
