Hello all, new member here and I absolutely love the site. I was hoping for some help from the experts. I bought a Quadrafire Sante Fe 2 years ago when I bought my house to replace an older Whitfield stove. It is vented out of the wall of my house, currently with about 1 ft. of pipe from the stove, to a 90 degree elbow, to a T, to another 90, then about 2 feet of pipe out of the house, all Selkirk piping (not sure how old). Towards the end of last year, and upon fire up this year, I have a smoke smell that is constantly there. I removed all of the piping, cleaned it out thouroughly, and reinstalled. I siliconed inside the pipes, and around all of the joints, and still have problems. I was seeing small plumes of smoke occasionally, so redid he joints, and it got a little better. I then removed the exhast fan, cleaned that out thoroughly, and reinstalled. The gasket for this was not in great shape, so I siliconed around the edge of the plate of the exhaust fan as well (not sure if this is recommeded?). I have noticed that I can feel a significant amount of air from inside the stove when I open the side door, it seems as if the exhaust fan is almost blowing out a little, is this normal? I think this is where my smoke smell is coming from, but can't figure out how to fix this. Is there anything else you can recommend I try to solve this problem? It has gotten much better since I re-did the piping and cleaned the exhaust fan area, but I can't get rid of the smell completely. Do you think my piping could be too old and should be replaced? My other question is can this smell be dangerous? I have 2 small kids, and I have not gotten any sign of CO2 from my detector, which is good. Sorry for the long winded post, any and all help is appreciated.
