Important Information About Efficiency And Quality - Rheem 801T Series Installation Instructions Manual

WARNING
!
BLOWER AND BURNERS MUST NEVER BE OPERATED
WITHOUT THE BLOWER DOOR IN PLACE . THIS IS TO
PREVENT DRAWING GAS FUMES (WHICH COULD CON-
TAIN HAZARDOUS CARBON MONOXIDE) INTO THE
HOME THAT COULD RESULT IN PERSONAL INJURY OR
DEATH .
WARNING
!
ALWAYS INSTALL THE FURNACE TO OPERATE WITHIN
THE FURNACE'S INTENDED TEMPERATURE-RISE
RANGE WITH A DUCT SYSTEM WHICH HAS AN EX-
TERNAL STATIC PRESSURE WITHIN THE ALLOWABLE
RANGE, AS SPECIFIED IN THE DUCTING SECTION OF
THESE INSTRUCTIONS . SEE ALSO FURNACE RATING
PLATE .
THE FURNACE MAY BE USED FOR HEATING OF BUILD-
INGS OR STRUCTURES UNDER CONSTRUCTION .
INSTALLATION MUST COMPLY WITH ALL INSTALLA-
TION INSTRUCTIONS INCLUDING:
- PROPER VENT INSTALLATION;
- FURNACE OPERATING UNDER THERMOSTAT CON-
TROL;
- RETURN AIR DUCT SEALED TO THE FURNACE;
-
AIR FILTERS IN PLACE;
- SET FURNACE INPUT RATE AND TEMPERATURE
RISE PER RATING PLATE MARKINGS;
- MEANS FOR PROVIDING OUTDOOR AIR REQUIRED
FOR COMBUSTION;
- RETURN AIR TEMPERATURE MAINTAINED BE-
TWEEN 55°F (13°C) AND 80°F (27°C); AND
-
CLEAN FURNACE, DUCT WORK AND COMPO-
NENTS UPON SUBSTANTIAL COMPLETION OF THE
CONSTRUCTION PROCESS, AND VERIFY THAT THE
FURNACE OPERATING CONDITIONS INCLUDING
IGNITION, INPUT RATE, TEMPERATURE RISE AND
VENTING, ACCORDING TO THE INSTRUCTIONS AND
CODES .
IMPORTANT INFORMATION ABOUT
EFFICIENCY AND INDOOR AIR
QUALITY
Central cooling and heating equipment is only as efficient as the
duct system that carries the cooled or heated air . To maintain
efficiency, comfort and good indoor air quality, it is important to
have the proper balance between the air being supplied to each
room and the air returning to the cooling and heating equipment .
Proper balance and sealing of the duct system improves the
efficiency of the heating and air conditioning system and im-
proves the indoor air quality of the home by reducing the amount
of airborne pollutants that enter homes from spaces where the
ductwork and / or equipment is located . The manufacturer and
the U.S. Environmental Protection Agency's Energy Star Pro-
gram recommend that central duct systems be checked by a
qualified contractor for proper balance and sealing .
WARNING
!
DUCT LEAKS CAN CREATE AN UNBALANCED SYSTEM
AND DRAW POLLUTANTS SUCH AS DIRT, DUST, FUMES
AND ODORS INTO THE HOME CAUSING PROPERTY
DAMAGE . FUMES AND ODORS FROM TOXIC, VOLATILE
OR FLAMMABLE CHEMICALS, AS WELL AS AUTOMO-
BILE EXHAUST AND CARBON MONOXIDE (CO), CAN BE
DRAWN INTO THE LIVING SPACE THROUGH LEAKING
DUCTS AND UNBALANCED DUCT SYSTEMS CAUSING
PERSONAL INJURY OR DEATH (SEE FIGURE 2) .
• IF AIR-MOVING EQUIPMENT OR DUCTWORK IS LO-
CATED IN GARAGES OR OFF-GARAGE STORAGE
AREAS - ALL JOINTS, SEAMS, AND OPENINGS IN
THE EQUIPMENT AND DUCT MUST BE SEALED TO
LIMIT THE MIGRATION OF TOXIC FUMES AND ODORS
INCLUDING CARBON MONOXIDE FROM MIGRATING
INTO THE LIVING SPACE .
• IF AIR-MOVING EQUIPMENT OR DUCTWORK IS LO-
CATED IN SPACES CONTAINING FUEL BURNING
APPLIANCES SUCH AS WATER HEATERS OR BOIL-
ERS - ALL JOINTS, SEAMS, AND OPENINGS IN THE
EQUIPMENT AND DUCT MUST ALSO BE SEALED TO
PREVENT DEPRESSURIZATION OF THE SPACE AND
POSSIBLE MIGRATION OF COMBUSTION BYPROD-
UCTS INCLUDING CARBON MONOXIDE INTO THE LIV-
ING SPACE .
