Hello to all - I bought a QuadraFire Santa Fe and it is being professionally installed by the person recommended from the hearth shop that sold me the stove. The installer was out once already to run the exhaust vent pipe and drop off the stove. However, the air intake adapter was on backorder, so he has to come back tomorrow to finish the job. He is using Simpson Duravent "pellet vent pro" pipe. At my exterior, he put in a wall thimble through the rim joist, but only used the exterior half because the interior there is not finished. Then he put the interior half at the ceiling level above my stove, where I plan to install a flush drywall ceiling. However the collar on the thimble is meant to extend into a 4+ inch wall cavity, but the venting pipe makes has a 90 degree elbow just above ceiling level, so the collar will not clear. I called the hearth store to ask about ordering a ceiling plate and he said that was a bad idea, and to just snip out a section of the thimble collar. I am about to do that myself, and will ask the installer about doing it when he is here, but I wonder if anyone here has thoughts on this? I am almost tempted to insist that he stick around while that piece of drywall goes up, as I think the whole thimble flange should go on the pipe AFTER the drywall, so I don't have to cut a hole that is bigger than the esuction and play carnival game to thread it up eight feet of pipe! Also, the 25 foot air intake pipe (flex chimney liner also from Simpson Duravent) was left on my floor at the last visit, and in between, during some of the other construction, it was partially crushed. This pipe was not cheap, and at first the hearth guy who is the one ordering all the pipe told me I should have one continuous intake pipe. Now he says he will send out a coupling and the installer can splice together two pieces of flex pipe. Does that sound kosher? Lastly, I read the checklist of things to go over with the installer. I even got a bag of pellets so I can run it for 20 minutes before he leaves. However, I just want to throw out whether there are any other things to go over with the installer (e.g., with this particular stove) that people here might know of? Thanks in advance!
