How is a concentric vent used in a high efficiency furnace?

Concentric vents make it easier to have a two-pipe installation for high efficiency furnaces. These vents simplify installation and only require one hole through the wall or roof where the pipes terminate. Without using these vents, the installation would require cutting two holes through the home, one for each pipe.

How long can a concentric vent be?

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.

What is a concentric pipe?

A concentric reducer is used to join pipe sections or tube sections on the same axis. The concentric reducer is cone-shaped, and is used when there is a shift in diameter between pipes. For example, when a 1″ pipe transitions into a 3/4″ pipe and the top or bottom of the pipe doesn’t need to remain level.

Do you glue concentric vent?

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 should a high efficiency furnace be vented?

Proper sidewall venting requires installing separate vent pipes horizontally so that they vent to the outdoors through a wall of your home. These ventilation pipes should be isolated from the furnace combustion chamber and made airtight to eliminate the possibility of combustion gas leakage.

Is the exhaust from a gas furnace dangerous?

One of the most important safety features of gas-condensing systems is furnace sidewall venting. Gas furnaces burn natural gas to produce heat. A by-product of this combustion process can be carbon monoxide, a very dangerous exhaust gas.

What does a concentric vent do?

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 does a concentric kit do?

How long can a furnace exhaust pipe be?

The maximum vertical distance you can run a furnace exhaust vent is about 15 feet. If there is a forced air inlet within 10 feet of the exhaust vent, the exhaust gas ventilation terminal should be positioned at least 3 feet above it.

How far can you vent high efficiency furnace?

about 15 feet
The maximum vertical distance you can run a furnace exhaust vent is about 15 feet. If there is a forced air inlet within 10 feet of the exhaust vent, the exhaust gas ventilation terminal should be positioned at least 3 feet above it.

Can a high efficiency furnace Backdraft?

High-efficiency or 90+% combustion furnaces and boilers do not vent flue gases through a standard chimney. Since there is a fan pushing the combustion gases out of the building, there is no chance that these appliances will backdraft.

How do you install a concentric vent on a furnace?

Use appliance installation instructions to determine pipe diameter. 2. Determine correct Concentric Vent size for the pipe diameter selected. 3. Determine the best location for the Concentric Vent. Use 4. Cut a 4” diameter hole for CVENT-2, 2” kit. 5. Partially assemble Concentric Vent kit. Follow furnace

How do you install a flue pipe on a wood stove?

Screw three sheet metal screws to connect the pipe sections, overlapping at least 2inches along the seams. Install a flue collar where the pipe connects to the stove. Apply fireproof sealant. Attach a chimney pot or rain stopper cap on top of the pipe to prevent rain from entering. Clean flue pipes annually when not in use for wood stoves.

What is the vent code for a gas furnace?

Once you know about the system and be familiar with the gas furnace vent pipe code, you can continue with the installation. furnace vent pipe installation code,gas furnace venting codes,furnace exhaust pipe code,furnace flue vent code,gas furnace exhaust pipe regulations

Where does a furnace vent pipe go through the roof?

This structure generally uses the furnace vent pipe through roof because the B venting pipe is designed in a vertical manner. When the vent is withdrawing air from the house, it expels the gas outside through the vent. The installation for this natural type is quite easy with a modest cost.

What kind of pipe do I need for a vent flue?

I began the installation of the new vent flue by purchasing schedule 40 PVC pipe in 2″ and 3″ diameters. The 2″ pipe leaves the furnace and connects to the 3″ pipe at the first turn. The 3″ diameter pipe is cellulose core, which is approved by my furnace manufacturer.

Can a vent flue be attached to an air compressor?

Don’t do this if you just want to wing it. Here’s the old vent flue as it left the furnace and made its first turn. You can see PVC attaching to galvanized Type B vent. Three Augusts ago, our 22 year old air compressor died on us.

How many vents do you need for a two pipe furnace?

Product Family Description: Concentric vents make it easier to have a two-pipe installation for high efficiency furnaces. These vents simplify installation and only require one hole through the wall or roof where the pipes terminate. Without using these vents, the installation would require cutting two holes through the home, one for each pipe.
