90+
96% Efficient
Power Direct Vent Commercial Gas Water Heater
The 100,000 BTU Force™ 90+ light-duty commercial gas water heater is equipped with a fully submerged, spiral-shaped condensing heat exchang-
er 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.
Power Direct Vent Design for Installation Versatility
• Modular blower, with 120V, 60Hz 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
4˝ pipe allows vent runs up to 128 equivalent feet
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
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
CSA Certified and ASME Rated T&P Relief Valve
Maximum Hydrostatic Working Pressure: 150 psi
Meets the thermal efficiency and standby
loss requirements of the U.S. Department
of Energy and current edition of
ASHRAE/IESNA 90.1
