WARNING
DO NOT EXCHANGE MEMORY CARDS BETWEEN 2 OR MORE DIFFERENT FURNACES. DOING
SO COULD RESULT IN UNEXPECTED OPERATION – INCLUDING INADEQUATE AIRFLOW DUR-
ING HEATING (AND OTHER MODES) OR A LOSS OF HEAT.
RECOGNIZE THIS SYMBOL AS AN INDICATION OF IMPORTANT SAFETY
INFORMATION!
IF THE INFORMATION IN THESE INSTRUCTIONS IS NOT FOLLOWED EXACTLY, A FIRE OR EXPLOSION
MAY RESULT, CAUSING PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
THESE INSTRUCTIONS ARE INTENDED AS AN AID TO QUALIFIED SERVICE PERSONNEL FOR PROPER
INSTALLATION, ADJUSTMENT AND OPERATION OF THIS UNIT. READ THESE INSTRUCTIONS
THOROUGHLY BEFORE ATTEMPTING INSTALLATION OR OPERATION. FAILURE TO FOLLOW THESE
INSTRUCTIONS MAY RESULT IN IMPROPER INSTALLATION, ADJUSTMENT, SERVICE OR

PROPOSITION 65 WARNING: THIS PRODUCT CONTAINS CHEMICALS KNOWN TO THE STATE OF
CALIFORNIA TO CAUSE CANCER, BIRTH DEFECTS OR OTHER REPRODUCTIVE HARM.
— Do not store or use gasoline or other flammable vapors and liquids, or other combustible materials
in the vicinity of this or any other appliance.
— WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use any phone in your building.
• Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's instructions
• If you cannot reach your gas supplier, call the fire department.
• Do not return to your home until authorized by the gas supplier or fire department.
— DO NOT RELY ON SMELL ALONE TO DETECT LEAKS. DUE TO VARIOUS FACTORS, YOU MAY NOT
BE ABLE TO SMELL FUEL GASES.
• U.L. recognized fuel gas and CO detectors are recommended in all applications, and their installa-
tion should be in accordance with the manufacturer's recommendations and/or local laws, rules
regulations, or customs.
— Improper installation, adjustment, alteration, service or maintenance can cause injury, property
damage or death. Refer to this manual. Installation and service must be performed by a qualified
installer, service agency or the gas supplier. In the commonwealth of Massachusetts, installation
must be performed by a licensed plumber or gas fitter for appropriate fuel.
