Using AutoFire® with a Kiln-Sitter® ®
If you have a Kiln-Sitter® on the kiln, you may use a Cone 10 bar or cone under the sensing rod to shut off
power if the kiln reaches high temperatures. This bar will last many firings. You can also remove the cone or
bar and prop up the sensing rod with a piece of refractory material. Set the Kiln-Sitter® timer for two hours
longer than the firing.
