The 50-gallon, 76,000 BTU Force™ 90 light-duty commercial gas water heater is equipped with a fully submerged, spiral-shaped condensing heat exchanger. This design provides a much greater heat transfer surface than a standard straight flue tube, resulting in 90% thermal efficiency and higher hot water output than comparable 80% efficient water heaters. With 22" diameter, the 50-gallon Force™ 90 can be installed in less space than a 75-gallon unit and delivers greater recovery and lower operating costs.

Features
Power Vent Design for Installation Versatility
  • Modular blower, with 120 volt, 60 Hz electrical system (5 amps or less), 6-foot cord with standard 3-prong connector.
  • Can be vented vertically thru-the-roof or horizontally thru-the-wall.
  • Combined horizontal and vertical vent runs terminating through outside wall, using PVC, CPVC or ABS pipe as follows:
    • 2" pipe allows vent runs up to 20 equivalent feet.
    • 3" pipe allows vent runs up to 60 equivalent feet.
    • 4" pipe allows vent runs up to 120 equivalent feet.
  • Supplied with PVC pipe and elbows to connect heat exchanger outlet to blower, including condensate elbow and drain.
  • PVC Vent Attenuation Assembly (VAA) supplied to help ensure extra-quiet operation.
Side-Mounted Taps for Recirculating Systems
  • Hot and cold "side taps" allow Force™ 90 to be used for "combination" systems for water heating plus space heating, radiant floor heating or other applications requiring a recirculating hot water loop.
  • Plugs for recirculating taps are factory installed.
Intelli-Vent® (Intelli-Vent® is a registered trademark of the Emerson Electric Company) Gas Control with Silicon Nitride Hot Surface Ignitor
  • Premium-grade hot surface ignitor eliminates standing pilot.
  • Electronic circuitry provides superior system diagnostic capabilities plus extremely precise temperature control.
  • 180 ºF maximum temperature setting.
Glasslined Tank with Two Magnesium Anode Rods
  • Provides superior protection against corrosion.
  • Glass lining protects all "water side" tank surfaces plus inside of internal heat exchanger exposed to condensate.
Low NOx Green Choice® Burner
  • Reduces NOx emissions up to 33% and meets low NOx emission requirements of less than 40 ng/j.
Pexan™ Diffuser Dip Tube
  • Helps reduce lime and sediment buildup, maximize hot water output.
  • Pexan™ cross-link polymer withstands long-term exposure to temperatures up to 400 ºF.




Testing and Certifications
CSA® Certified and ASME Rated T&P Relief Valve
Maximum Hydrostatic Working Pressure: 150 psi Compliance
  • Design-certified by UL (Underwriters Laboratories) according to ANSI 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




Warranty
  • 3-Year Limited Tank Warranty.




Note
All models - Maximum Supply Pressure: 14 inches W.C. (3.48 kPa)

Minimum Supply Pressure Natural Gas: 5.0 inches W.C. (1.24 kPa)

Minimum Pressure must be maintained under both load and no load (Static and dynamic) conditions.

Recovery Capacities - U.S. Gallons/Hr. and Liters/Hr. at Temperature Rise Indicated

Recovery capacity based on 90% thermal efficiency

Install in accordance with local codes
