Okay, so 4 or so firings later, and I'm still no closer to solving this mystery.
Everything is still attached correctly. I even uninstalled the duct and used a shorter more direct route from kiln to vent.
Seems to stank up my house even when there is no wind.
Holding a match over the lid holes, I do see the flame being pulled in a bit, and when I go outside there is a lit of air being blown out the vent.
Anybody have any other suggestions? Do I just call skutt and try to troubleshoot? At this point I'm really frustrated because I spent $400 and got this thing, and my house still smells like death by cancer. :/
All the peephole plugs were in. I'll try checking with a match when I get home (kiln is off now, but the vent is still running). I guess it could be the wind interfering with it. I dont remember what the weather was like when I first noticed the problem.
Another thought- does how the kiln is packed make a difference in the vent's functionality?
Also, on the dehumidifier thing, I use one sometimes, but it can dry stuff out FAST (including eyes and lips, haha). So if you leave it on and you're out of the studio for a day you can come back a pile of ware that's too dry to work with anymore. :/
