WARNING
This warning is presented for compliance with California
Proposition 65 and other regulatory agencies and only
applies to the insulation in this product. This product con-
tains refractory ceramic, refractory ceramic fiber or fiber-
glass insulation, which can produce respirable dust or fi-
bers during disassembly. Dust or fibers can cause irrita-
tion and can aggravate pre-existing respiratory diseases.
Refractory ceramic and refractory ceramic fibers (after
reaching 1000°C) contain crystalline silica, which can
cause lung damage (silicosis). The International Agency
for Research on Cancer (IARC) has classified refractory
ceramic fiber and fiberglass as possibly carcinogenic
(Group 2B), and crystalline silica as carcinogenic to
humans (Group 1).
The insulating materials can be located in the door, the
hearth collar, in the chamber of the product or under the
hot plate top. Tests performed by the manufacturer indi-
cate that there is no risk of exposure to dust or respirable
fibers resulting from operation of this product under nor-
mal conditions. However, there may be a risk of exposure
to respirable dust or fibers when repairing or maintaining
the insulating materials, or when otherwise disturbing
