Kiln Sitter with Electric Valve for Gas Kilns
A kiln sitter may be ordered with your Torchbearer gas kiln or added later. If the kiln is installed with a kiln sitter, the kiln sitter electrical box on the kiln plugs into a standard 120-volt outlet. The electric valve plugs into the receptacle on the kiln sitter box.
Gas kiln sitter systems may be retrofitted after the purchase of the kiln. To add a kiln sitter to a Torchbearer kiln, drill a 1-inch hole in the exposed brick area of the kiln for the kiln sitter tube assembly to go through. Mount the kiln sitter electrical box to the
kiln and secure it to the kiln body with #6 sheet metal screws. Screw the electric valve to the burner manifold, paying attention to the gas flow direction embossed on the valve.
The kiln sitter with timer is a mechanical device that will shut the kiln down once it reaches temperature. Pyrometric cones are inserted into the kiln sitter cone supports and once the kiln reaches temperature the cone will bend and mechanically shut down the kiln. The timer is usually set 30 minutes beyond the estimated firing time and will shut down the kiln if the cone in the kiln sitter does not. During the firing, the kiln operator will open the gas valve in 45-minute increments from low to medium
to high to reach the desired temperature. When firing a gas kiln with a kiln sitter it is a good idea to have a pyrometer to know the temperature inside the kiln and witness cones on shelves to determine accurate firings.
