To Tinknocker11 or anyone who can help. Re: New information on an old topic...mystery solved!

I have some photos that might be of interest to you and others, but I wasn't successful in posting photos, previously, without your help. Looking for help, once again.

Thanks,

Whatthehay?

I have some photos that might be of interest, regarding my furnace problem of condensate running back down the combustion vent intake to combustion box. Based on these photos, does anyone care to offer an explanation, as to why this concentric didn't work correctly? Thanks!

couldn`t get 3rd & 4th pic to open

BUT

is that concentic homemade???????????

Hacks, as you had already found out. Thats not the way to make it longer.

It looks like the installer cut the concentric kit right in the middle, so he could lengthen the concentric, rather than lengthen the two pipes coming from the furnace.

Don't know why 3 and 4 wouldn't open for you... I just tried it and it went right to the photo site. Perhaps, try again?

This is Turtle.

You sure your looking at the furnace vent pipe and not the sewer drain vent pipe ? I'm lost looking at that home made kit.

that homemade hackery belongs on the wall of shame. no wonder you had water problems, i'm suprised that thing ran at all.

It is hard to determine size of the pipes from the photos. Sorry I didn't post size of the pipes used in making up this concentric. The outer top pipe is 4", but then the guy necked it down to 3" before it arrives at the Y. Of course there is still a 2" pipe inside, so that didn't leave much of a gap for the air intake.

I made the discovery of condensate getting into the combustion when I got a call from my wife, telling me the furnace had quit running. I pulled off the front access panel, only to find the water leaking out of the combustion box. The code told me the problem that shut off the furnace was a pressure switch, so I tapped the switch and turned the furnace back on. That was last November, and surprisingly, it has seemed to run ok ever since. I'm sure glad to have the hacked concentric replaced by a friendly tech, who knows his stuff.

That hadn't occurred to me, and you may be right (it could be a sewer pipe), but I found it connected to the vents coming out of the top, front of the furnace, and running through the attic to the roof.

what a mess. Why would a installer even mess with a concentric kit if he penetrated the outside wall with 2 pipes. It'd be a lot easier just to terminate em the tradional way. It looks like that piece he's trying to extend it with, is blocking the intake air. I'd be getting a different company out there to fix that.

Done. That's how I was able to get my hands on the hacked concentric.

Thanks for the input.
