Note:
Do not be concerned if your kiln makes a
clicking sound during firing. Kilns use relays to
power the elements.The relays click each time their
electrical contacts come together.
Note:
The kiln’s actual firing rate may be less than
the rate you programmed, depending on the kiln
model, available voltage, and density of load you are
firing.
When the kiln fires to completion, it will beep for 30 sec-

The power failed during firing and temperature
dropped more than 180°F / 100°C by the time the power

Thunder Storms and Power Surges
Unplug the kiln or disconnect the power when the kiln is
not in use, especially during thunder storms and in areas
with frequent power surges. If the kiln is part way through a
firing when a storm begins, it is probably okay to continue
the firing with close supervision. Do not leave the kiln unat-
tended.
