WARNING
!
Hazardous Gases!
Exposure to fuel substances or by-products of incomplete
fuel combustion is believed by the state of California to
cause cancer, birth defects, or other reproductive harm.
Carbon monoxide, fire or smoke can cause serious
bodily injury, death, and/ or property damage.
A variety of potential sources of carbon monoxide can be
found in a building or dwelling such as gas-fired clothes
dryers, gas cooking stoves, water heaters, Furnaces and
fireplaces. The U.S. Consumer Product Safety Commis-
sion recommends that users of gas-burning appliances
install carbon monoxide detectors as well as fire and
smoke detectors per the manufacturers installation in-
structions to help alert dwelling occupants of the pres-
ence of fire, smoke or unsafe levels of carbon monoxide.
These devises should be listed by Underwriters Labora-
tories, Inc. Standards for Single and Multiple Station
Carbon Monoxide Alarms, UL 2034 or CSA Interna-
tional Standard, Residential Carbon Monoxide Alarming
Devices, CSA 6.19
NOTE: The manufacturer of your Furnace does NOT test any
detectors and makes no representations regarding any
brand or type of detector.
Connect duct work to Furnace. See Outline Drawing for
supply and return duct size and location. Flexible duct
connectors are recommended to connect both supply
and return air ducts to the Furnace. If only the front of
the Furnace is accessible, it is recommended that both
supply and return air plenums are removable.
