State Industries Electric Heater FORCE 90TM User Manual

FORCE 90  
90% EFFICIENT  
Power-Vent Commercial Gas Water Heater  
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 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.  
Power-Vent Design for Installation Versatility  
• Modular blower, with 120 volt, 60Hz electrical system (5 amps or less), 6-foot cord with  
standard 3-prong connector  
• Combined horizontal and vertical vent runs terminating through outside wall,  
using Schedule 40 PVC pipe as follows:  
- 2" pipe allows vent runs up to 25 equivalent feet  
- 3" pipe allows vent runs up to 65 equivalent feet  
- 4" pipe allows vent runs up to 128 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®* 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°F maximum temperature setting  
Glass Lined 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%, complies with Southern California and Texas  
requirements  
PEXANDiffuser 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°F  
Factory-Installed Temperature and Pressure Relief Valve  
Maximum Hydrostatic Working Pressure: 150 psi  
Meets ASHRAE/IESNA 90.1-1999  
• 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  
warranty information

SUGGESTED SPECIFICATION  
(Natural or Propane) gas water heater(s) shall be State Force 90 model # SHE50 76NE, with 90% thermal efficiency, a storage capacity of 50 gallons, an input rating of 76,000  
BTUs per hour, a recovery rating of 83 gallons per hour at 100ºF rise and a maximum hydrostatic working pressure of 150 psi. Water heater(s) shall be of power-vent design,  
using 2", 3" or 4" PVC pipe for horizontal and/or vertical vent runs. Water heater(s) shall have: 1: Seamless, glass lined steel tank construction and a spiral-shaped heat  
exchanger placed entirely inside the tank, which shall be glass lined on the flue gas side to protect against acidic condensate. 2: An Intelli-Vent gas control system with silicon  
nitride hot surface ignitor. 3: A 3-year limited warranty against tank leaks. Water heater(s) shall meet or exceed ASHRAE/IESNA 90.1-1999, and be design-certified by UL
