Air intake for utility room?
My house has a small utility room with a gas water heater and no ventilation to/from the outside (other than the gas heater duct of course!).
I have the exhaust issue solved--a 5" duct with inside elbow leading down toward the floor, but what is the appropriate device to use for through-wall intake <12" below the ceiling? I presume something with a damper defeats the purpose.
I live in the California Bay Area so cold air is not a giant concern.
Thanks a lot.

Gas heater duct ?? Would that be the flue line ?
You would use an outside hood with no damper for fresh air in..... in a temperate zone.
If you were in a cold zone.... you'd want a motorized damper.
For a water heater...... a 4" vent is plenty.
I'm not sure what you are referring to at 12" below the ceiling.

Thank you! Just what I needed to know. The code says these openings must be within 12" of the ceiling.
