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)
• Combined horizontal and vertical vent runs terminating through outside wall,
using Schedule 40 PVC 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
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
Glass Lined 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 up to 33%, complies with Southern California and
Texas requirements
Factory-Installed Temperature and Pressure Relief Valve
Maximum Hydrostatic Working Pressure: 150 psi
Meets ASHRAE/IESNA 90.1 (latest standard)
• Design-certified by UL (Underwriters Laboratories) according to
ANSI Z21.10.3-CSA4.3 standards governing storage-type water heaters
Three-Year Limited Tank Warranty
• Consult written warranty shipped with water heater or contact State for complete
