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.
GLASS-LINED TANK – 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).
