Steady drip at ehxaust

I just assumed he had the manual, but he didn`t really say. If not, he can get-it from their site.<BR><BR>Dave

Drip at exhaust

Had a CGi-3 installed last year. From the beginning it had several small drips, first from the low water cut-off, then from bottom of the fan cage. They fixed the first, but still have not been able to stop the one by the fan. In fact, they cannot tell me what they think it is. I have placed small containers on the floor beneath the cover, and it continues to drip, running down the boiler cover to fill the container. The lower left corner of the fan's mounting, at the bolt, has begun to rust. Might this become a problem? What could cause this drip?

Here are a few photos that may help explain my situation.

The installing company and I get along pretty well, and they are willing to fix any problems. But they are at a loss to explain it. I'm figuring the condensate is somehow getting past the tee in the stainless exhaust. That's about all I can think of. I need a bit of help here. . .

From what I can see

The basement environment must be pretty humid as some of the pipe fittings appear to be rusting too. This will eventually take its toll on the burners as well. Is this a large water content (converted gravity) system? I can`t tell by your pics but is there any kind of bypass piping to get the boiler up to operating temp faster? If this is the only circ, I wonder why they put it on the return.

condensation

I can't see from the pics but how is it vented, out the sidewall or into a chimney. ? If in chimney, did they line chimney with a liner on not. Is the gas pressure correct on unit? All these will come into play. Tim

Thanks

No, this is not a conversion. This system, the boiler and the fintube (2 floors, 450 sq ft per floor, 3 walls, because one wall adjoins nex door). It is vented out the side wall, about 23 feet away. On that run they have used 1 45, and at least 4 90s. They just installed the condensate pump 2 weeks ago, because I didn't like the condensate being run into a piece of 3/4 tubing drilled into the basement floor. But, if you look, you will see rust stains already forming atop the label on the pump. Should the circulator be on the supply side? They are willing to correct any problems, and they have been doing so since the job was "finished" last year. Any ideas or suggestions?

I would sure bet

that would condense, and run back. I`ve never seen a vent termination done quite like that, but I`m also not familiar with your codes there. Looking at the requirements WM gives, I can`t find anything like that. Have you looked in your boiler manual? What kind of SS venting material is it?
(Edit)- Is the condensate drain tee located close to the boiler? Do they have a little "pigtail-type curly-Q" in the plastic drip tube leaving this?

Thank you


Dave, I believe the SS is E_Z seal. But, no, there is no pigtail coming off the tee. The exhaust leaves the boiler, comes straight up, about 2 feet, then breaks at a 90 degree turn, running horizontal, and the drain tee is just after it breaks. I'll see if I have a photo of it. As I said, I am not trying to fight with the installers. We actually get along pretty well. But I am trying to get the job corrected so that it is running correctly . . . which is what I paid for, after all. The actuall installer/serviceman who installed the pump advised me that he has no idea why it is dripping out of the fan/inducer cage. I suspect, if not corrected, this watery problem will shorten the life of my boiler and/or the inducer fan. Help . . . . Oh, I am in the Neptune, NJ area

It no doubt will

at least ruin the blowers fan! The little tube coming off that tee must have this little "trap" in it to keep the blowers pressure from dissipating the forming condensate away from the drain hole itself inside. Much like the drain from a F/A furnaces A/coil, otherwise it`ll run right back into the blower housing. It will also pass CO into the house!! Not sure how that got by an inspector.
(Edit)- After seeing that pic, I`ll bet that`s a BIG part of your problem!! Again, check your manual on the venting requirements, it`s there.
Hope this helps. BTW- I`m on the other side of the border LOL!

Stumpted

After speaking to the installers again, they don't know what could be causing this to happen. So I am stumpted. I'd like to find out how to stop it.

Weil-McLain is well represented in your area. I would get the local rep to take a look at your boiler. Either have your installer contact them through the supplier(most likely in Long Branch or Avon)or contact them yourself.

There are some things I would have done differently on the piping, but without the installation manual in front of me, I can't say they are wrong.

Excellant point Shane,

I never asked

Ooops, I had faith . . .

Call it foolharty. I trusted the company, who has been in business for over 50 years. Granted, it has been one small problem after another. But they have come back and corrected one after another. This one seems to have them stumped. Me too. I will fetch the OM and read it carefully. Yet I am sure there are many shoulds, coulds and suggestives orttos. Frankly, I've never seen one of those pigtales on a drain before. We only use them on gauges on steam pipes. But i like the idea. Lost in the drip . . . .
