Delphi Ceramic Kiln Instruction Manual

Delphi Ceramic Kiln
Instruction Manual
INTRODUCTION
Thank you for purchasing a Delphi kiln. We are confi-
dent that the kiln will give you many years of relaxation
and creative enjoyment.
The warranty on your kiln does not cover damage from
overfiring, regardless of the circumstances. It is the oper-
ator's responsibility to make sure the kiln turns off when
the firing is completed. Never leave your kiln unattended
near the end of the firing.
Since the insulating firebricks expand and contract
with each firing, hairline cracks will appear in the bricks
while the kiln is cold-even in a new kiln. Do not be con-
cerned with these. They are normal. The cracks close
tightly when the heated bricks expand. The cracks func-
tion as expansion joints and will not affect the firing.
Do not be concerned with the light that appears
around the edge of the lid. As long as the lid is closed all
the way, there is little heat loss. Discolored paint is also
inevitable and doesn't affect firing results.
IMPORTANT SAFETY RULES
● There is little danger of serious burn from acciden-
tal contact if you exercise the same caution you
would use with an electric iron.
Place the kiln on the stand that came with the kiln.
●
When a kiln is safety tested, the lab fires the kiln on
the stand designed for it. Cinder blocks or bricks
can inhibit the flow of air under the kiln. They can
also change the kiln's heating characteristics.
Place the kiln on a non-combustible surface.
●
Do not install closer than 12" from any wall or com-
●
bustible surface.

Fire only in a well ventilated, covered, and protected
●
area.
Do not open the lid until kiln has cooled to room
●
temperature and the switch is turned off.
Dangerous voltage: do not touch the heating ele-
●
ments with anything.
Disconnect kiln before servicing.
●
Do not leave kiln unattended while firing. Do not
●
leave a kiln turned on at your studio while you are at
home sleeping.
Wear firing safety glasses when looking into a hot
●
kiln.
Keep the kiln lid closed when the kiln is not in use.
●
This keeps dust out of the kiln. Also, should some-
one turn on the kiln while you are away, the closed lid
will keep the heat safely inside the firing chamber.
Never place anything on the kiln lid, even when the
●
kiln is idle. If people become accustomed to placing
papers and other objects on the kiln, they may forget
and do that while the kiln is firing.
Remove all tripping hazards from around the kiln.
●
Keep the kiln's supply cord out of traffic areas.
Do not let the cord touch the side of the kiln, which
●
may damage the cord.
Avoid extension cords.
●
Wear gloves when you load and unload your kiln.
●
The gloves should be thick enough to protect you
from glaze shards and bits of pyrometric cones that
have stuck to shelves, sharp edges of broken ware,
and sharp stilt marks on the bottom of glazed ware.
