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

• 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

• Reduces NOx emissions up to 33%, complies with Southern California and Texas requirements

PEXAN

• 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
