IMPORTANT: All Rheem products
meet current Federal OSHA Guidelines
for safety. California Proposition 65
warnings are required for certain prod-
ucts, which are not covered by the
OSHA standards.
warnings for products sold in California
that contain, or produce, any of over
600 listed chemicals known to the
State of California to cause cancer or
birth defects such as fiberglass insula-
tion, lead in brass, and combustion
products from natural gas.
All "new equipment" shipped for sale in
California will have labels stating that
the product contains and/or produces
Proposition 65 chemicals. Although we
have not changed our processes, hav-
ing the same label on all our products
facilitates manufacturing and shipping.
We cannot always know "when, or if"
products will be sold in the California
market.
You may receive inquiries from cus-
tomers about chemicals found in, or
produced by, some of our heating and
air-conditioning equipment, or found in
natural gas used with some of our
products. Listed below are those chem-
icals and substances commonly asso-
ciated with similar equipment in our
industry and other manufacturers.
• Glass Wool (Fiberglass) Insulation
• Carbon Monoxide (CO)
• Formaldehyde
• Benzene
More details are available at the
Websites for OSHA (Occupational
Safety and Health Administration), at
www.osha.gov and the State of
California's OEHHA (Office of
Environmental Health Hazard
Assessment), at www.oehha.org.
Consumer education is important since
the chemicals and substances on the
consumers are aware that products
present safety and health risks, when
improperly used, handled and main-
tained.
Installation Instructions are updated on
a regular basis. This is done as product
changes occur or if new information
becomes available. In this publication,
an arrow ® denotes changes from the
previous edition or additional new
