Re: Ventilation requirements for natural gas water heater
It depends on where the water heater is. If in the home and drawing air from the home then the door should probably be sealed with weather stripping and combustion air brought in from the attic with a pipe just abobe floor level. Also a screened opening in the ceiling for ventilation for the unit. Of course this all depends on the location of the unit and the size of the unit for proper sized combustion air supply. You should consult a plumber for proper codes and installation.
