looking for condensate vent cover
 
1 Attachment(s)
We experience a problem during high winds where it appears that our gas fired furnace fails.

Quite annoying, we have theorized that a missing condensate vent cover is the problem. During high winds an internal pressure switch shuts off the gas to our furnace as wind creates a pressure difference if it blows "just right." And "just right" is any high wind whipping around our house.

Our neighbors have a "baffle" covering their vents, however we do not (we had one that the builder "kindly" left under our deck;the deck framing prevented its attachment; in the intervening five years it has been misplaced/lost/thrown away/stolen).

The photo attached shows the vent "baffle."

The condensate vent is a dual-pipe, larger pipe enveloping a smaller pipe. The cover shown seems to allow the inner pipe to exhaust, while the cone allows intake and provides some wind protection.

We have not been able to find a similar cover at Lowes, Home Depot, Ace, or other builder supply. It's possible because we do not know what it is called (other than "vent cover"/"baffle"). We have taken pictures to stores only to "baffle" the salesforce (pun intended).

Any help in finding this cover would be appreciated. Any thoughts on our theory would be nice too. :)

Thats known as a concentric vent.

The end piece is not sold separately.
You will need to buy the entire thing($$$$). And then just use the end cone.

Without it. Most likely the wind is blowing the exhaust fumes back into the intake pipe. And causing a flame failure.

Another solution as a temp fix. is to get 2-PVC 90 ells, and a 12" long piece of 2" PVC(guessing your vent pipe is 2") And attach one ell to 90 the exhaust up or to the side. The 12" piece to extend it away from the intake. And use the other 90 to direct the vent fumes from the house.

Generally, they should not exhaust under a deck.

Thank you! After giving it a name, other than baffle, I could find it on "Google"!

$$$$ is right. Ugh.

Regarding the deck exhaust... it doesn't do this now, we replaced the deck sometime ago. Now, I have a 45 down on the outside pipe to provide some "protection" though I don't think it does much for the flame outs in the wind.

Much thanks again!

Post a pic of how you have it venting now.

Been is correct. The cone is not sold separately. I have had this request several times this year and have not been able to locate a source for the cone only.

Good Luck

If you have no affiliation with them. Yes it is.

I get it, but I don't GET IT. As I said, it is my company, so there is a lot of affiliation. I will remove my post so someone here can promote someone who does not contribute or support this forum.

You can leave your post.

I believe it has to do with self free advertising.

But, because I am a forum member, I am prohibited from saying what I just said (crap...did it again). So, what ultimately will happen is that someone else will post a link to a company that sells CV kits to help the OP, and this will be a company that is not affiliated with the forum. Where my frustration comes into play is when this happens, I have to watch the missed opportunity, while I am involved in offering DIY support.

Now, with that said, I do GET IT. Without this policy, the forum would be filled with self promoters and would become a watered down version of Craig's List and not the resource that is today. ...Still Frustrating Though....

OK, sorry OP for the thread hijack. Let's get back to the business at hand. your vent will be either 2" or 3" at the furnace. From that you can order your next CV Kit if that is what you decide to do. If you get the correct size, and order one like you see in your picture, you will be fine. they are all basically the same (of that configuration) for standard home gas furnaces.

Imagine how some pro's must feel when they see you giving advise to someone that is in their area. And they miss out on a service call that would have made them money.

No difference, since they can't promote themselves either.

Besides. Your screen name will let posters find you on the net.

I assume that is the neighbors pic. Without the hood it will never work properly. Get the installer to come back and replace the kit and have it flush to the house. A DIFFICULT job for an DIYer to do as both sets of pipes need connecting in the house at the SAME time and a skilled plumber/installer to do that or it will leak etc.

Marty S. 01-03-2010 02:00 PM

If the intake hood will not fit because of the deck location then run the intake and exhaust seperate. Take them past the deck to avoid recirculation and insulate the exhaust that's outside.

yuri 01-03-2010 02:04 PM

Gotta be careful with the length of run, # of elbows etc. Depending on type of furnace some are finicky. Carriers like a certain configuration which is different than the Goodmans etc. Need to follow the manufacturers recommendations or have more problems later. Uninsulated exhaust pipe under a deck is tricky! Must be sloped back properly and insulated REAL well or it will freeze up. I avoid them like the plague.:censored:

@yuri, et al., The deck is no longer there. Yes, the photo is a neighbor's vent. The neighborhood as a whole has a varied selection of these vents. The first 5 or 6 homes built seem to have the CV "option." The remainder, have a separated exhaust/intake piping on the exterior.

A CV vent cover could be easily added today... if I could get one. :)

@beenthere, HAD, what we have now on the exterior of the home is a DIY's misunderstanding of what the vent was to begin with. Sometime ago, I added the 45 elbow shown in the attached (after we removed the old deck and replaced with one that no longer obstructs/blocks the vent and lost the termination cover). Note that the elbow only directs down. No piping is provided to for exhaust pipe directly.

I only determined last night, after reading the furnace op manual, that it was the condensate vent and that exhaust blowback or blockage could create a flame out, as designed by the manufacturer. Note, that this situation has intermittently existed for five years, I do not believe it has been damaging, just annoying when the furnace won't stay on in bitter cold and windy weather (just when you need it) :blink:.

Looking at CVs online, it is very unlikely that myself, or a contractor, is going to replace the CV whole. I won't have it, or pay for it. The basement is finished and to replace is to demo the ceiling into the joists for access.

I really only need the cover. If there were not an intervening 5 years (since the house was built) I might argue to the building contractor (listed on the furnace) that "they owe me a CV cover."

I'll look around for CV parts, but as HAD notes, if as a contractor it is nigh impossible to buy, it might mean purchasing whole for just for the cover. :censored:

Thanks for all the replies! :thumbsup:

You have the option of paying to advertise on this site
And what you mentioned is the problem...the forum filling up with people just advertising their product
There are probably 1-5 people banned every day who come on here just to advertise
We do have to apply the rules across the board
