So after the install about three weeks ago I had smoke from an unsealed pipe. I called the company and they sent the same installers back out. I couldn't see the smoke but I could smell it now. Somebody else comes out and fixes my problem. I do a check over and find this. I have never looked in there before so I don't know if its normal. Any ideas? something to worry about or is it something the gentleman did yesterday sealing something?
