User’s Information
Never store gasoline, combustible materials, or other
fl ammable liquids or vapors near your furnace.
Carbon monoxide, fi re 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-fi red clothes
dryers, gas cooking stoves, water heaters, furnaces and
fi replaces. The U.S. Consumer Product Safety Commission
recommends that users of gas-burning appliances install
carbon monoxide detectors as well as fi re and smoke dectec-
tors, listed by a nationally recognized agency (e.g. Under-
writers Laboratories or International Approval Services), to
help alert dwelling occupants of the presence of fi re, smoke
or unsafe levels of carbon monoxide.
NOTE: The manufacturer of your furnace does not test any
detectors and makes no representations regarding any
brand or type of detector.
Installing and servicing heating equipment can be hazard-
ous due to gas and electrical components. Only trained and
qualifi ed personnel should install, repair or service heating
equipment.
Untrained personnel can perform basic maintenance func-
tions such as cleaning and replacing fi lters. All other opera-
tions must be performed by trained service personnel.
Parts and controls of this furnace are unique. Should ser-
vice or modifi cation be required, be sure your servicer uses
only factory authorized parts, kits, or accessories for this
furnace.
If you experience a problem with the operation of your
furnace, check the “Problem Solver” section of this manual
before you call for a possibly unneeded service call.
