Commercial Gas Water Heaters
All models are approved for use in combined appliance applications.
FEATURES
CFC-FREE FOAM INSULATION – Minimizes radiant heat loss.
DIP TUBE – Carries inlet water deep into tank.
HOT SURFACE IGNITION – Has a solid state ignition surface that does not flutter or blow out.
Provides increased reliability and efficiency over spark ignition systems. Eliminates the pilot and
saves energy.
INTELLI-VENT CONTROL – Provides temperature control and LED diagnostics.
GLASSLINED TAN K – Glass specifically developed by A. O. Smith for water heaters is permanently
fused to steel at 1,600° F, providing years of corrosion protection and dependable use.
ANODE – Tank-mounted, screw-in replaceable anode for longer tank life.
HIGH INPUT – 80,000 BTU input assures plenty of hot water is available by providing faster
recovery rates and higher first hour draws.
BURNER – High input, multiport burner for improved combustion efficiency and low NOx.
TURBO SHOT™ COMBUSTION SYSTEM – Air is precisely drawn through the combustion
control port and exhausted through plastic pipe. Controlling the airflow through the heater
enhances and regulates the combustion process. In standby mode, the combustion control port
restricts air circulation through the heater.
POWERED VENTING – Provides more venting flexibility and savings. A new quiet blower allows
exhaust venting through the roof or sidewall with plastic pipe such as PVC, CPVC, and ABS.
Allowable vent lengths of up to 100 equivalent feet make installation easy in any situation.
BTF-80 is a Category 3 (positive pressure non-condensing) appliance.
BUILT-IN CONDENSATE FITTING – A condensate management coupling that attaches vent
pipe to the blower and drain hose are included.
INSTALLED TEMPERATURE & PRESSURE RELIEF VALVE – Factory installed and matched to
the heater. (Specify if your local code requires a special T&P).
Three year limited tank warranty - For complete warranty information, consult written
warranty.
