Need code statement.

Sorry bout this. I am in the middle of a move and have packed my tech reference materials. I have a 1992 gas water heater installed in a bedroom closet. No makeup air being drawn from the exterior, natural venting type.

Thanks

Not on "that" computer at the moment but probably best to download the manufacturers install manual and use that for reference.

Thanks guys.

I would search for the installation manual online.

Most of them will show a 4" vent pipe installed for combustion air.

The closet door should have an airtight seal, but I will suggest drywall the door opening and cut a new door in from the hall if possible.
