CONSERVATIONIST® POWER VENT
Commercial Gas
Water Heaters
APPROVAL RATINGS AND
CERTIFICATION
• All models comply with: ANSI Z21.10.3/CSA 4.3
and ASHRAE/IES 90.1 – 2004
• Meets Texas and other low NOx areas requiring
40ng/j
• All models are approved for use in combined
appliance applications.
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.
USER-FRIENDLY
• State-of-the-art electronic gas control provides
more precise temperature control.
• LED control light displays operation status and
diagnostics information.
ENHANCED-FLOW BRASS DRAIN
VALVE
• Have a solid brass, tamper resistant, enhancedflow, ball type, drain valve.
• Uses a standard female hose fitting that allows for
fast and easy draining during maintenance.
• Designed for easy operation, this valve includes
an integral screwdriver slot that features a ¼ turn
(open/close) radius, which not only permits full
straight-through water flow but also a quick and
positive shut off.
BLUE DIAMOND® GLASS COATING
• Provides superior corrosion resistance compared to
the industry-standard glasslining.
STANDARDS
• Design-certified by CSA International, according
to ANZI Z21.10.3 - CSA 4.3 standards governing
storage-type water heaters.
• Meets the thermal efficiency and standby loss
requirements of the U.S. Department of Energy and
current edition of ASHRAE/IESNA 90.1.
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, ABS, and polypropylene.
• Up to 125 equivalent feet of pipe make
installation easy in any situation.
• BTF-80 is a Category 3 (positive pressure noncondensing) appliance.
ANODES
• Tank-mounted, screw-in magnesium anodes for
longer tank life.
HIGH INPUT
• 76,000 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.
BUILT-IN CONDENSATE FITTING
• A condensate management coupling that
attaches vent pipe to the blower is included.
INSTALLED TEMPERATURE &
PRESSURE RELIEF VALVE
• Factory installed and matched to the heater.
(Specify if your local code requires a special T&P).
