WARNING
contains ceramic fiber material. Ceramic fibers can
be converted to cristobalite in very high temperature
applications. The International Agency for Research
on Cancer (IARC) has concluded, "Crystalline silica
in the form of quartz or cristobalite from occupational
sources is carcinogenic to humans (Group 1)". Normal
operating temperatures in this appliance are below the
level to convert ceramic fibers to cristobalite. Abnormal
operating conditions would have to be created to convert
the ceramic fibers in this appliance to cristobalite.
The ceramic fiber material used in this appliance is
an irritant; when handling or replacing the ceramic
materials it is advisable that the installer follow these
safety guidelines.
 Avoid breathing dust and contact with skin and
eyes.
• Use NIOSH certified dust respirator (N95).
This type of respirator is based on the OSHA
requirements for cristobalite at the time this
document
respirators may be needed depending on the job
site conditions. Current NIOSH recommendations
can be found on the NIOSH website at
http://www.cdc.gov/niosh/homepage.html.
NIOSH approved respirators, manufacturers, and
phone numbers are also listed on this website.
