L&L Kiln Mfg, Inc. 505 Sharptown Rd, Swedesboro NJ 08085 P:856.294.0077 F:856.294.0070 [email protected] hotkilns.com
1. Plastics, organic materials, bakeable modeling clay,
mothballs and a large variety of materials can decompose
under heat causing the release of highly toxic fumes or
rapid uncontrollable combustion.
2. Rocks, marbles, cement and other materials may explode
under high temperatures.
3. Before firing anything but ceramics, glass and metal
(obtained from a known reputable source) in a kiln carefully
investigate what happens under heat.
4. This is the sole responsibility of the user.
5. The kiln is not designed to be used for firing hazardous
materials. Doing so will void kiln warranty.
6. Adding propane, wood, charcoal or other materials
intended to produce a reduction atmosphere can be
hazardous if the volume is sufficient. Note that these
materials can cause an explosion under certain conditions
(just the right amount of air and flammable gasses at just
the right temperature) which could cause injury or death.
Moreover, a reducing atmosphere can cause premature
element failure by reducing the protective oxide coating on
the elements. Also note that carbonaceous materials will
produce poisonous carbon monoxide and highly flammable
hydrogen as they decompose at high temperatures. Also
note that the “auto-ignition” temperature of flammable
gasses is generally above 1400° F.
LOADING & UNLOADING CAUTIONS
TURN OFF POWER WHILE LOADING
1. Turn off power to the kiln when loading or servicing.
2. If power is on when you are loading or unloading the kiln
it is possible to touch the elements and get electrocuted.
3. We recommend having the kiln attached to a fused
disconnect switch with a lockout device (in any institutional
or industrial installations where someone could turn on the
kiln while someone else was working on it).
KEEP LID CLOSED WHEN KILN IS NOT IS USE
1. Keep lid closed when not operating the kiln.
2. Otherwise the weight of the lid over time may force the
hinge and stainless wrap to move down.
3. This will affect the way the lid closes and may cause the
lid to crack.
4. It will also keep the kiln cleaner by keeping dust out.
5. In addition, if the kiln somehow gets turned on accidentally,
an open kiln could present a fire hazard.
DO NOT STORE ANYTHING ON LID
#1
POTTER
1. Do not use the lid as a storage shelf.
2. The lid could crack.
3. Also - this practice could lead to a fire if you accidentally
leave combustible materials on the lid.
DO NOT OPEN THE DOOR ABOVE 250
