96 percent thermal efficiency and storage up to

125 gallons, SHIELD has everything it takes to provide the ultimate green operation C without the risk of lime scale buildup. Ideal for green commercial buildings, SHIELD provides low NOx ratings compatible with the most stringent air quality standards. The NEG/REG sealed combustion system allows the unit to operate with inlet gas pressure as low as four inches of water column and delivers a quiet, environmentally friendly supply of heat. For added flexibility, SHIELD offers rooftop or sidewall venting options, including conventional, direct vent and concentric direct vent, all using PVC or CPVC pipe with vent runs up to

100 feet. Utilizing a fully modulating burner with 5:1 turndown, SHIELD can fire as low as

20 percent of maximum input when demand is lowest, and increase to

100 percent for peak- demand periods. This results in better overall efficiency and less cycling compared to "on-off" tank-type units that can only fire at full force. Smart Design, SMART CONTROL? In addition, SHIELD is equipped with an advanced water heater control, which makes system setup, service and operation a breeze. The innovative SMART CONTROL? features a two-line, 16-character backlit LCD display that provides readouts of setup, system status and diagnostic information in words, not codes. SMART CONTROL also includes night setback, time clock, alarm contacts, runtime contacts and manual-reset high limit. The outstanding life cycle efficiency and performance of SHIELD can serve even the highest demand commercial applications through manifolded installation of multiple units. For example, five SHIELD SNA

500 models can provide a total storage of

625 gallons with maximum input of 2.5 million Btu/hr. Another key advantage with SHIELD is that the storage tank features very high drawdown for more usable hot water, faster.
