WARNING
PROPOSITION 65: This appliance contains fiberglass insulation. Respirable
particles of fiberglass are known to the State of California to cause cancer.
All manufacturer products meet current Federal OSHA Guidelines for safety.
California Proposition 65 warnings are required for certain products, which are
not covered by the OSHA standards.
California's Proposition 65 requires warnings for products sold in California
t
hat 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
h
ave not changed our processes, having 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 customers 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

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 consumers are aware that products pre-
sent safety and health risks, when improperly used, handled and maintained.

WARNING
The first 36 inches of supply air plenum and ductwork must be constructed of
sheet metal as required by NFPA 90B. The supply air plenum or duct must have a
solid sheet metal bottom directly under the unit with no openings, registers or
flexible air ducts located in it. If flexible supply air ducts are used they may be
located only in the vertical walls of a rectangular plenum, a minimum of 6 inches
from the solid bottom. Metal plenum or duct may be connected to the combustible
floor base, if not, it must be connected to the unit supply duct flanges such that
combustible floor or other combustible material is not exposed to the supply air
opening from the downflow unit. Exposing combustible (non-metal) material to the
supply openings of a downflow unit can cause a fire resulting in property damage,
personal injury or death.
