Residential Power Vent Combi1™ TTW
Gas Water Heater System
The Combi1™ TTW® FVIR Defender Safety System® Models Feature
Photo is of
(50T model, only):
■ Advanced ScreenLok
is designed to prevent ignition of flammable vapor outside of the water heater.
■ Flammable Vapor Sensor—Electronic sensor prevents burner operation if
flammable vapors are detected. The sensor will also prevent operation if there is
ongoing flammable vapors burning inside the combustion chamber.
■ Maintenance Free—Regular cleaning of air inlet openings or flame arrestor is
not required under normal conditions.
■ Sight Window—Offers a view of the pilot and burner operation.
All Combi1
™
TTW® Models Feature
■ Internal Single Wall Heat Exchanger—1
steel coil.
-- 1" (25mm) NPT Solar Collector Supply and Return Connections.
■ Low Heat Exchanger Head Loss—Up to 10 GPM (38L) flow, with less than 5ft.
(1.5m) of head loss. Greatly reduces the required pump size for heat exchange.
■ Honeywell Self Diagnostic Electronic Gas Control —Intelligent gas control
with spark to pilot ignition system eliminates the constant burning pilot. This
results in savings of pilot gas during stand by periods (120 VAC).
-- Enhanced Performance—Proprietary algorithms provide enhanced First Hour
Rating and tighter temperature differential.
-- 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.
■ Factory-Installed Hydrojet
device 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
1600°F (871°C).
■ Horizontal and Vertical Venting—With 3" (76mm) or 4" (102mm) PVC, ABS or
CPVC (Maximum equivalent vent lengths on reverse side).
■ 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
extend water heater life and simplify water line connections.
■ Two Protective Anode Rods.
■ T&P Relief Valve—Installed.
■ Low Restrictive Brass Drain Valve—Durable tamper proof design.
■ Thermostatic Mixing Valve (ASSE Approved)—Included.
