IMPORTANT: All Manufacturer 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.

California's Proposition 65 requires

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 insulation,

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, having

the same label on all our products facili-

tates manufacturing and shipping. We

cannot always know "when, or if" prod-

ucts will be sold in the California market.

You may receive inquiries from cus-

tomers about chemicals found in, or pro-

duced by, some of our heating and air-

conditioning equipment, or found in nat-

ural gas used with some of our products.

Listed below are those chemicals and

substances commonly associated 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 list

are found in our daily lives. Most con-

sumers are aware that products present

safety and health risks, when improperly

used, handled and maintained.

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 mater-

ial.

IMPORTANT: To insure proper installa-

tion and operation of this product, com-

pletely read all instructions prior to

attempting to assemble, install, operate,

maintain or repair this product. Upon

unpacking of the furnace, inspect all

parts for damage prior to installation and

start-up.
