Safety
The warranty on your Sentry controller
does not cover damage from overfiring,
regardless of the circumstances. It is the
operator's responsibility to make sure
the kiln turns off at the proper time.
Follow these safety rules in addition to
the ones in your kiln or furnace manual.
When the kiln is not in use, disconnect the
power.
Do not leave the kiln unattended, especially
near the expected shut-off time.
Wear firing safety glasses when looking into
the peephole of a hot kiln.
Do not touch hot sides of kiln or furnace.
Keep unsupervised children away.
Install your kiln or furnace at least 12 inches
from any wall or combustible surface.
Do not open lid or door until kiln or furnace
has cooled and all switches are off.
Fire only in a well-ventilated, covered and pro-
tected area away from combustible materials.
Keep cordset away from hot sides of kiln or
furnace.
DANGEROUS VOLTAGE! Do not touch
heating elements with anything. Disconnect
kiln or furnace before servicing.
