Can I vent my water heater horizontally?
The venting can run either vertically or horizontally with a longer line to help with space and sizing issues within your home, which makes power vent water heaters more flexible to install. Power vents are a more efficient option, as they are designed to utilize heat from the exhaust to heat water for energy savings.
How high does a water heater vent need to be?
For a single-wall pipe, you need 6″ clearance, and you cannot pass it through a ceiling, floor, or wall unless it’s masonry or concrete (non-combustible). For the draft hood connection, you need to allow for at least 12″ of vertical vent before throwing an elbow fitting in the line.
Can you put a power vent on a water heater?
Power vents simplify a gas hot water heater installation
Reduce high electric bills by replacing an electric water heater with a natural gas or propane heater, then reduce installation costs by installing a power-vented model that can be easily vented out a sidewall.
Can a tankless water heater share vent?
No common venting.
The tankless heater cannot share vent piping with any other appliance, and it cannot use a masonry chimney flue for venting.
Do gas water heaters need fresh air?
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.
Can you vent a tankless water heater into furnace vent?
When installing a tankless water heater, you have to consider the type of heater to guide you on what kind of venting you will need. Since a high-efficiency gas water heater produces corrosive combustion gases, you should avoid connecting it with the furnace vent or other existing vents for other appliances.
How far can you vent a direct vent water heater?
Power-vented natural gas water heaters use an electric fan or blower to push or pull combustion gases to the outdoors. This type of venting allows gas water heaters to be installed as far as 40 feet away from an outside wall and in homes without existing vertical vents.

Can I use PVC to vent gas water heater?
A standard will be needed for plastic flue pipes that should include a temperature gauge and a high limit probe. Then PVC, CPVC and polypropylene flue gas piping can be safely used on high efficiency boilers and water heaters.
What happens if a water heater is not vented properly?
A vent connector is the thing that takes the exhaust gases from the top of the water heater (draft hood) to the vent. If a vent connector isn’t properly installed, the potential for the water heater to backdraft increases.

What is the difference between a direct vent and power vent water heater?
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.
Are direct vent water heaters more efficient?
A power vent water heater also offers more energy efficiency when compared to a direct vent water heater. By utilizing a fan to operate the power vent, your water heater will require less gas to operate, which means it will require less energy to operate, and it will cost less to operate.
Can I replace a direct vent with a power vent?
A direct vent system pulls in air from outside and then vents the exhaust through a horizontal pipe. This difference in operation means that you can install a direct vent system almost anywhere, but a power vented water heater must be placed in a room with adequate airflow.
