Defender Safety System ® , ScreenLok ® , TTW ® , Vitraglas
"Highest in Subcontractor Satisfaction among Water Heater/Boiler Manufacturers"
The TTW ® 4 FVIR Defender Safety System
Advanced ScreenLok
I
to prevent ignition of flammable vapor outside of the water heater
Flammable Vapor Sensor—Electronic sensor prevents burner operation if flammable
I
vapors are detected. The sensor will also prevent operation if there is ongoing flammable
vapor burn inside the combustion chamber.
Maintenance Free—No regular cleaning of air inlet openings or flame arrestor is required
I
under normal conditions.
Sight Window—Offers a view into the combustion chamber to observe the operation of the
I
pilot and burner.
Pedestal Base—Rugged and durable base allows easy transport and positioning, and
I
provides corrosion resistant contact with floor.
All TTW ® 4 Models Feature:
Powerful Blower Motor—Our design has higher torque for greater resistance to outside
I
winds and the power to eliminate problems with difficult venting situations. This significantly
quieter motor runs cooler for a considerably longer operational life.
Spark-to-Pilot Ignition System—Eliminates the constant burning pilot used on other water
I
heaters. This device results in savings of pilot gas during standby periods (110 VAC required
to heater).
Electronic Gas Control Valve—The integrated, immersion gas control valve offers more
I
precise temperature control for higher first hour delivery and also allows water temperature
adjustment without removing the cover. The control is equipped with an LED to display
heater status and aid in diagnostics.
Horizontal and Vertical Venting—With 3" or 4" PVC, ABS, or CPVC (Maximum equivalent
I
vent length on reverse side).
Vitraglas ® Lining—Bradford White water heater tanks are protected from the corrosive
I
effects of hot water by a ceramic porcelain-like coating. The exclusive high silica ceramic
lining provides a tough interior surface for our water heater tank.
More Precise Temperature Control—With an adjustable temperature up to 180° F. Not
I
recommended for 180° F sanitizing.
Stainless Steel Flue baffle—Designed to maximize the amount of heat absorbed in the
I
lower portion of tank. Reduces air movement in the heater during standby periods to retard
heat loss up the flue.
Steel Tank—Heavy gauge steel automatically formed, rolled and welded to assure a
I
continuous seam for glass lining.
Side Connections—Side tappings allow easy connection for space heating applications.
I
Protective Magnesium Rod—Provides added protection against corrosion for long
I
trouble-free service.
Factory Installed Hydrojet
I
reducing device. Helps prevent sediment build up in tank. Increases first hour delivery of hot
water while minimizing temperature build up at top of tank. (TW4-75S has Factory Installed
Hydrojet ® ).
Factory Installed Heat Traps—Design incorporates a flexible disk that reduces heat loss in
I
piping and eliminates the potential for noise generation.
Water Connections—3⁄4" NPT factory installed true dielectric fittings. Extends water heater
I
life and eases installation.
2" Non-CFC Foam Insulation—Saves energy by retarding loss of heat.
I
Brass Drain Valve.
I
T&P Relief Valve Installed.
I
Design Certified by CSA International (formerly AGA and CGA).
I
3 or 5-Year Limited Tank Warranties / 1-Year Limited Warranty on Component Parts.
