In addition to venting, gas and propane water heaters need an air supply for combustion.

Some water heater venting systems remove the possibility of backdrafting with fan-assisted ventilation or direct venting technology.
Atmospheric Venting
Standard water heatersthe most common typeoften use a method known asatmospheric venting.
The vent consists of a vertical or upward-sloping vent duct that typically ties into a common vent.
The system works solely through natural convectionbased on the principle that hot air rises.
The power of the draw increases as the vent duct heats up.
Poorly designed vents commonly have insufficient draw and/or are highly susceptible to backdrafting.
The water heater must have a nearby electrical outlet for powering the fan.
They also reduce the risk of accidental fires resulting from flammable vapors around the water heater.
A standard atmosphericwater heater hook up in a mobile homeoften requires an outside access panel.
