FEATURING:
Gas Water Heater System
The Combi2® FVIR Defender Safety System® Model Features (C-DW2-504T10FBN
model only):
■ Advanced ScreenLok
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 vapors burning inside of the
combustion chamber or restricted air flow.
■ Maintenance Free—Regular cleaning of air inlet openings or flame arrestor is not
required under normal conditions.
■ Sight Window—Offers a view into the combustion chamber to observe the operation
of the pilot and burner.
All Combi2® Models Feature:
■ Bradford White ICON System
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.
-- Enhanced Performance—Proprietary algorithms provide enhanced First Hour
Rating and tighter temperature differential.
-- Advanced Temperature Control System—Microprocessor controls burner
operation for consistent and accurate water temperature levels up to 180°F (82°C).
-- Intelligent Diagnostics—Exclusive multicolor LED light indicates operation status/
service required.
■ Internal Double Wall Heat Exchanger—Double wall 1
(Vitraglas
®
) steel coil ensures separation of potable water and heating fluid.
-- 3/4" (19mm) NPT Front Supply and Return Connections.
-- Low Heat Exchanger Head Loss—Up to 8 GPM (30 LPM) flow, with less than 6 ft.
(1.8m) of head loss. Greatly reduces the required pump size for heat exchange.
■ Factory Installed Hydrojet
that also increases first hour rating 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
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.
■ Pedestal Base.
■ Water Connections—3⁄4" (19mm) NPT factory installed true dielectric fittings.
■ Two Protective Anode Rods.
■ T&P Relief Valve—Installed.
■ Low Restrictive Brass Drain Valve—Durable tamper proof design.
■ Thermostatic Mixing Valve (ASSE Approved)—Included.
