The Concentric Vent allows both the intake for combustion air and the exhaust vent to pass through a standard roof or sidewall. This is an alternative to the standard two pipe intake/vent shown in the basic furnace installation instruc-tions. Follow these instructions as well as the basic furnace installation instruction for installation of the intake/vent pipe(s) and all furnace installation procedures.

What is a concentric vent?
Concentric venting describes any coaxial "pipe in pipe" venting design where the intake air and exhaust gas both vent through a shared assembly. It can provide an aesthetic installation with a single wall or roof penetration.
What is a concentric roof vent?
The Concentric Vent allows both the intake for combustion air and the exhaust vent to pass through a standard roof or sidewall. This is an alternative to the standard two pipe intake/vent shown in the basic furnace installation instructions.

What is a concentric vent used for?
The Concentric Vent allows both the intake for combustion air and the exhaust vent to pass through a standard roof or sidewall. This is an alternative to the standard two pipe intake/vent shown in the basic furnace installation instructions.
Is a concentric vent a direct vent?
Concentric venting may be used with several types of water heaters, including direct vent, power direct vent, and tankless water heaters. However, the material of the concentric venting may be different depending on the water heater.
What is a concentric vent water heater?
A concentric vent design consists of insulated intake and outtake pipes within the 5-inch concentric vent which enable the water heater to remain cold on the outside and prevent the risk of burn injuries from coming into contact with a hot water heater.
How close can concentric vents be?
Allow 8” center-to-center distance between concentric vent terminations on multiple boiler installations (see Fig. 7). It is very important to properly glue all joints. Failure to do so can result in property damage, serious personal injury, or death.
How does a concentric flue work?
A concentric flue system provides a very compact room sealed flue, where the air supply and flue gases are managed within a one-piece concentric duct system. Typically using a duct within a duct, flue gases are expelled through the inner duct with combustion air being drawn in via the outer annulus.
Does a concentric vent need a cap?
Unlike standard vent termination hubs, concentric vent terminations have the appearance of a small pipe extending out from a cone or saucer. Unfortunately the exhaust pipe extending out from the cone is prone to entry by birds and insects, which is why this opening must be protected by a suitable cap with screen.
How is a concentric vent used in a high efficiency furnace?

What is the proper way to vent a gas water heater?
There should be a minimum of 12 inches of vertical venting between the draft hood outlet and the first elbow or connecter. When using direct venting, any semi-horizontal piping should have a minimum upward slope of one quarter-inch per foot.
How do I know if my water heater is direct vent?
Difference in terms of venting pipe:A power vent water heater exhausts the gases or fumes through a PVC or other plastic pipe venting.A direct vent water heater does that through metal venting.
Can you extend a concentric vent?
You can extend the concentric vent kit up to 60" by replacing the piping between the concentric Y fitting and the rain cap. You must use SDR-26 PVC pipe.
Can concentric vent be shortened?
The pipe length of the concentric vent kit can be shortened, provided that the cutting and welding procedures adhere to the System1738 guidelines outlined in this guide. NOTE: THE PIPE LENGTH OF THE CONCENTRIC VENT KIT CANNOT BE LENGTHENED. 7.
Can you paint concentric vent?
You can paint a concentric black if needed.
What is a power direct vent?
Much like direct venting, power direct venting uses a blower to pull in air from outside your home for combustion and funnels it directly to your water heater. The same blower is also used to release the combustion exhaust gases back outside of your home. Similar to the power vent design, a power direct vent water heater can utilize PVC piping ...
Why are power vents so efficient?
Power vents are a more efficient option, as they are designed to utilize heat from the exhaust to heat water for energy savings. Thanks to lower exhaust temperatures they allow for PVC piping, which is a less expensive solution than a standard atmospheric vent metal piping and easier to assemble.
What is a direct vent water heater?
Direct vent gas water heaters are a type of gas water heater best suited for use when there is insufficient ventilation within the installation space in your home. A direct vent water heater draws air for combustion from outside your home rather than inside. The exhaust gases and excess heat produced by your water heater are then vented back ...
How does a power vent work on a water heater?
Smith power vent gas water heaters are equipped with an electric blower fan that is installed on top of the water heater, which requires an electrical outlet to be close to the water heater. The blower pushes the exhaust and excess heat through the exhaust venting. 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.#N#Power vents are a more efficient option, as they are designed to utilize heat from the exhaust to heat water for energy savings. Thanks to lower exhaust temperatures they allow for PVC piping, which is a less expensive solution than a standard atmospheric vent metal piping and easier to assemble. We recommend that you consult a professional plumbing contractor for installation.
How does an atmospheric vent work?
Atmospheric venting works on the principle of hot air rising. 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.
Can a direct vent water heater be used as an outlet?
Similar to the power vent design, a power direct vent water heater can utilize PVC piping to reduce installation costs. It is important to note that they also require an electrical outlet near the water heater for installation.
Can a water heater be concentric?
It can provide an aesthetic installation with a single wall or roof penetration. Concentric venting may be used with several types of water heaters, including direct vent, power direct vent, and tankless water heaters. However, the material of the concentric venting may be different depending on the water heater.
1. Concentric Vent
A concentric vent uses a double vent pipe, with the outer pipe being PVC, and the inner pipe is of Stainless Steel.
2. PVC Vent (Schedule 40)
A PVC Vent (schedule 40) is similar to a concentric vent in that it also uses dual venting pipes. However, unlike an inner stainless steel pipe, both these pipes are made of PVC schedule 40. You can see such a type of venting in a condensing tankless water heater, which is a gas tankless water heater variant.
3. Horizontal vs. vertical venting
You can do the venting of the tankless water heater in two ways. Namely, a vertical way and a horizontal way. Vertically, a vent exhaust gases to the outside through the roof. Such venting needs you to install a top above it to prevent rain and debris from getting it. While horizontally, the vent goes through the wall to exhaust the gases outside.
4. General knowledge for venting tankless water heaters
Gas tankless water heaters require proper venting. However, if you have an outdoor tankless unit, you do not need to install a vent.
