Electronics Temperature
(ELEC)
Check the Circuit Board Temperature
High temperatures in the switch box can damage the
controller circuit board, which is rated for 158°F/70°C max-
imum operating temperature. If necessary, exhaust hot air
from the room to lower board temperature.When firing
several kilns, position them at least three feet apart to allow
adequate air circulation.
From or while firing, press
