The 100,000 BTU Force™ 90+ light-duty commercial gas water heater is equipped with a fully submerged, spiral-shaped condensing heat exchanger and 50 gallons of storage capacity. This design provides much greater heat transfer surface than a standard straight flue tube, resulting in 96% thermal efficiency and higher hot water output than comparable 80% efficient water heaters. With a 22" diameter, the Force™ 90+ can be installed in less space than a 75-gallon unit yet delivers greater recovery and lower operating costs. The Force 90 is ENERGY STAR® Qualified.

Unit of Measure: Imperial Metric Both

Power Direct Vent Design for Installation Versatility
  • Modular blower, with 120 V, 60 Hz electrical system (5 amps or less).
  • Can be vented vertically thru-the-roof or horizontally thru-the wall.
    Vents using PVC, CPVC or ABS pipe.
    • 2" pipe allows vent runs up to 45 equivalent feet.
    • 3" pipe allows vent runs up to 128 equivalent feet.
  • Optional concentric vent and sidewall termination kits available.
Available in Natural Gas or Propane

Side-Mounted Taps for Recirculating Systems
  • Hot and cold "side taps" allow the 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.
Advanced Electronic Control
  • Large LCD display.
  • Precise temperature control.
  • Advanced diagnostics.
  • iCOMM™ Compatible and can be monitored from remote locations.
Glasslined Tank with Two Magnesium Anode Rods
  • Provides superior protection against corrosion.
  • Commercial-grade glass lining protects all "water side" tank surfaces plus inside of internal heat exchanger exposed to condensate.
Top-Fired Low NOx Burner
  • Reduces NOx emissions and complies with SCAQMD Rule 1146.2, and other Air Quality Management. Districts with similar requirements for low NOx emissions.

Testing and Certifications
  • CSA® Certified and ASME Rated T&P Relief Valve
  • Meets the thermal efficiency and standby loss requirements of the U.S. Department of Energy and Current Edition ASHRAE/IESNA 90.1

  • 3-Year Limited Tank Warranty.

All models - Maximum Supply Pressure: 14 inches w.c. (3.48 kPa). Minimum Supply Pressure Natural Gas: 3.5 inches w.c. (.87 kPa). Minimum Pressure Propane: 8.0 inches w.c. (1.99 kPa). Minimum Pressure must be maintained under both load and no-load (static and dynamic) conditions.

Install in accordance with local codes.
