In response to Re: hot water heater
An upper and lower vent with one free inch of area for each 1,000 btu's of input. You can duct the lower one down from the attic if you do not have an exterior wall to put the vent into.

: I've installed lots of hot water heaters but what is the latest on combustion air vents for nat. gas models? Should a vent be in the floor and ceiling and how big should these vents be. Hate to put holes in the floors...pier and beam homes.
