Linchimb Posted Sunday at 09:54 PM Report Share Posted Sunday at 09:54 PM Hi Everyone, I recently got an installed a new Nabertherm Top 80 and just did a first firing to season the kiln elements. The instruction manual shows the pre-set programmes for bisque and glaze firing. It mentions that the fresh air valve needs to be closed manually when it reaches 600 degrees. I don’t recall any manual intervention when I was using a Northern kiln….I’m wondering if I can just leave the valve open if I am away from studio? The fresh air valve is located towards the bottom of the kiln where a small hole is drilled on the bottom with a handle to open/shut it. Many thanks!

neilestrick Posted Monday at 05:13 PM Report Share Posted Monday at 05:13 PM Where does this fresh air enter the kiln, and how big is the opening? Quote Link to comment Share on other sites More sharing options...
Linchimb Posted Monday at 05:29 PM Author Report Share Posted Monday at 05:29 PM Hi, it’s this small hole on the base of the kiln I believe (see picture). Thanks Quote Link to comment Share on other sites More sharing options...
neilestrick Posted 17 hours ago Report Share Posted 17 hours ago I would just leave that half open for the entire firing if you don't have some other vent system connected to the kiln. Quote Link to comment Share on other sites More sharing options...
