Concentric Vents High Efficiency Furnaces

The concentric vent allows both the intake for combustion air and the exhaust vent to pass through a standard roof or sidewall.

Concentric vents high efficiency furnaces.

Some high efficiency furnaces also include a plastic pipe for intake area and all types use a third plastic pipe to drain away the corrosive condensation resulting from the combustion process. These pvc pipes are connected to the furnace and expelled outside. This high efficiency venting system must be installed when you install the new furnace. Refer to the furnace installation instructions for intake vent pipe sizing information.

The vent kit is ideal if you do not want to cut two holes in your roof or wall to vent the furnace. In contrast modern high efficiency condensing furnaces exhaust much cooler gasses and need only plastic pipe materials such as pvc cpvc or abs for their exhaust vents. The 24 volt draft induced units include a standard vent kit that can be cut to fit wall thicknesses from 5 32 and includes an external vent cap which eliminates the need for expensive venting and unnecessary labor. Other aspects of high efficiency furnace venting.

These vents simplify installation and only require one hole through the wall or roof where the pipes terminate. Concentric vent kit for high efficiency gas furnace dcvk 20 two inch. This item is accepts two inch pipe. Without using these vents the installation would require cutting two holes through the home one for each pipe.

Description this item is used for a two pipe high efficiency gas furnace. This is an alternative to the standard two pipe intake vent shown in the basic furnace installation instructions. The pvc pipes are used for air intake exhaust gas and to remove the corrosive condensation resulting from the combustion process. Concentric vents make it easier to have a two pipe installation for high efficiency furnaces.
