The EcoStor2
™
 Single Coil Defender Safety System
®
 Models feature:
■  Backup Low NOx Burner—To activate burner, a thermistor temperature sensor is 
located in the upper portion of the tank to promote greater solar operation efficiency.
■  Internal Double Wall Heat Exchanger—1
1
⁄2" O.D. glass coated (Vitraglas
®
) steel coil 
ensures separation of potable water and heating fluid.
-- 3/4" NPT Solar Collector Supply and Return Connections.
■  Sensor Wires for Solar Thermistor Connections—Twisted wires are provided 
under the Upper and Lower covers (Thermistors and Solar Controller are not 
provided).
■  Honeywell Self Diagnostic Gas Control—Intelligent gas control with proven 
millivolt powered technology and built-in piezo igniter. A standard, off the shelf 
thermopile converts heat energy from the pilot flame into electrical energy to operate 
the gas valve and microprocessor. No need for external electricity.
-- Advanced Temperature Control  System—Microprocessor constantly monitors 
and controls burner operation to maintain accurate water temperature levels.
-- Intelligent Diagnostics—An exclusive green LED light prompts the installer during 
start-up and provides ten different diagnostic codes to assist in troubleshooting.
-- Pilot On Indication—Flashing green LED provides positive indication that pilot is 
on.
■  Defender Safety System
®
 (S-DW2-504 & S-DW2-65T only).
-- Advanced ScreenLok
®
 Technology Flame Arrestor Design—Flame arrestor is 
designed to prevent ignition of flammable vapor outside of the water heater.
-- Resettable Thermal Switch—Proven and reliable bimetallic switch prevents 
burner and pilot operation in case of ongoing flammable vapor burn inside of the 
combustion chamber or restricted air flow.
-- Maintenance Free—No regular cleaning of air inlet openings or flame arrestor is 
required under normal conditions.
-- Sight Window—Offers a view into the combustion chamber to observe the 
operation of the pilot and burner.
■  Factory Installed Hydrojet
®
 Total Performance System—Sediment reducing 
device that also increases first hour delivery of hot water while minimizing 
temperature build-up in tank.
■  Vitraglas
®
 Lining—An exclusively engineered enamel formula that provides 
superior tank protection from the highly corrosive effects of hot water. This formula 
(Vitraglas
®
) is fused to the steel surface by firing at a temperature of over 1600°F 
(871°C).
■  Insulation System—2" (51mm) Non-CFC foam insulation covers the sides and top 
of the tank, reducing heat loss. This results in less energy consumption, improved 
efficiencies, and jacket rigidity. Blanketed models additionally use a supplied flexible 
fiberglass insulation blanket.
■  Water Connections—3⁄4" (19mm) NPT factory-installed true dielectric fittings extend 
water heater life and simplify water line connections.
■  Two Protective Anode Rods.
■  T&P Relief Valve—Included.
■  Low Restrictive Brass Drain Valve—Durable tamper proof design.
■  Thermostatic Mixing Valve (ASSE Approved)—Included.
