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. These vents save time and money by reducing the amount of work required. Available in 2-inch, 3-inch, or 4-inch intake vent sizes.

Would there be an appreciable amount of heat absorbed by the intake air side? Considering mounting an outdoor temp sensor in the intake for humidifier control. Would appreciate your opinion.

Since the OD of the kit is a half size (3.5in or 4.5in), can you help sourcing a collar for a vertical roof install? All the collars I find are 2, 3, 4.. in sizes. Obviously, getting a good seal to the roof is very important. Thanks.

I just installed a new high efficiency furnace, can I use this pipe and run my exhaust and intake pipe up through my existing 6” exhaust vent that goes from the basement up through the roof that my old furnace used?

I have two horizontal furnaces in the attic can I use both furnaces to tie into the 3 inch exhaust and intake? I just wanted to know if I could just use one connector instead of two going outside of the house. Both are 3 ton 60k btu. Thanks!

I see a little bit of water dripping from the inside / intake side of the pipe. Should I be concerned?

I realize the PVC exhaust pipe running back to the furnace needs to be sloped, but in a horizontal install, should the CVENT be perfectly level/perpendicular with the exterior wall? In other words, would only the pipe from the CVENT back to the furnace have the 1/4" per foot slope, or does the entire assembly, including the CVENT, need to maintain the slope?

How do you remove the outer PVC rain cover to replace the pipe jack when getting a new roof? I am guessing our installer glued the inner pipe….

@Dojautlopez Год назад

Yes is glued. The flashing changes and over laps I believe. New construction we leave the top not glued until roof is complete

I'll never understand an open top vent. When they installed my furnace exhaust water came down the pipe and into my closet space and started rotting out the floor before I put a 90 on it..Maybe they forgot the 90? Either way I don't want water coming into my tankless even if it does have a condensate line.

@user-bx3zz9cx3y 7 часов назад

I had the same problem, but my vents were turned down. The water was leaking from the joints of the PVC vent pipe. The joints were not properly glued, allowing water to leak out and onto the drywall. I thought it was a roof leak, but it was because the home builder didn’t know how to glue a simple PVC joint. As long as the condensate drain is clear, there is no risk of water intrusion from an open top vent pipe.

How do you deal with heavy rain? Is there a way to cover top opening?

@joel4210 Год назад

Came here for this answer. I’m installing a indoor tankless water heater and need to vent it. I saw these concentric vents but wondering about the open vent.

@Phil-D83 Год назад

Prob add a 90*

@crislopes4518 Год назад

I was here for same question for a tankless water heater. Philip Dias. You suggest a 90 but wouldn’t the intake be sucking in water at that point? I’m doing a vertical termination. I guess it’d be the same problem for a horizontal termination.

@@joel4210 what did you end up doing?

What did you do? Did you get an answer from somebody?
