Direct. With direct vent installations, there is a sealed combustion chamber and a flue pipe. They can vent separately or together through a double-wall pipe. Compared to atmospheric, direct-vent water heaters offer more installation flexibility because they can vent horizontally.
Also to know is, can a direct vent water heater be vented vertically?
Venting layout
The venting system of the gas water heaters might consist of one or two pipes. The two-pipe system can be further divided into the concentric (pipe inside the pipe) system, and a system with two separate pipes. The vents can run horizontally, vertically, or combined.
Besides, can you put a gas water heater in a closet?

Can you vent a water heater out the side of a house?
This water heater is found in different homes, including mobile homes that require it to be placed outside. Atmospheric venting operates by the difference between the pressure and temperature from the outside and inside of the house to migrate the exhaust gas upward and throughout the vertical pipe.
Do gas water heaters need fresh air?
Water Heater Venting Basics
In addition to venting, gas and propane water heaters need an air supply for combustion. This may come from the atmospheric air in the house, or it can come through a vent pipe that pulls air from the outdoors.
Is a power vent water heater worth it?
Since a power vent water heater eliminates the potential for backdraft, they greatly lower the risk of carbon monoxide poisoning, although it is not totally eliminated. Energy savings is another benefit. Power vent water heaters are more energy efficient, so they require less gas to operate.
What is the difference between direct vent and atmospheric vent?
Basically, the difference between the two is that the power vent water heater removes combustion gases from the atmosphere via a powered venting fan, while a direct vent water heater vents these gases into the outdoor atmosphere using a chimney or exhaust pipe.
What is the proper way to vent a gas water heater?
The venting must be vertical or upward sloping so that the hot exhaust rises up through the venting to exit your home. Making sure that your home has a properly working vent system is imperative when installing a standard atmospheric vent with your water heater.
What is Type B gas vent?
DuraVent Type B Gas Vent is designed to meet the rugged demands of the job site. The inner wall is recessed to eliminate damage in handling. Type B Gas Vent has been engineered to heat up rapidly. It remains hot during the operation of the appliance with minimal condensation in the appliance and vent system.
Where do you vent a gas water heater?
In both cases, the water heater needs to be located near an exterior wall or a chimney for the venting system to work properly. On some gas water heater models, a power vent blower fan will be used to draw the exhaust fumes through the flue.
