Bradford White Corp Water Heater TTW4 User Manual

355-B 0506  
Light Duty Commercial Energy Saver Gas  
Through-The-Wall Water Heaters  
The TTW4 Models Feature:  
I Power Vented Heater—Designed for installations where atmospheric units  
cannot be used. Exhaust gases are vented under positive pressure directly  
out of the building through the wall or the roof.  
I Powerful Blower Motor—Our design has higher torque for greater  
resistance to outside winds and the power to eliminate problems with difficult  
venting situations. This significantly quieter motor runs cooler for a  
considerably longer operational life.  
I Spark-to-Pilot Ignition System—Eliminates the constant burning pilot used  
on other water heaters. This device results in savings of pilot gas during  
standby periods (110 VAC required to heater).  
I PVC, ABS or CPVC Venting—Horizontal and vertical venting up to 60  
equivalent feet for 3" pipe, and up to 90 equivalent feet for 4" pipe. See  
reverse side for specifics.  
®
I Vitraglas Lining—Bradford White water heater tanks are protected from the  
corrosive 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.  
I More precise temperature control—with an adjustable temperature up to  
180° F. Not recommended for 180° F sanitizing.  
I Steel Tank—Heavy gauge steel automatically formed, rolled and welded to  
assure a continuous seam for glass lining.  
I Side connections—Side tappings allow easy connection for space heating  
applications.  
I Protective magnesium rod—Provides added protection against corrosion  
for long trouble-free service.  
I Factory installed Hydrojet Total Performance System—Cold inlet  
®
sediment 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.  
I Factory installed Heat Traps—Design incorporates a flexible disk that  
reduces heat loss in piping and eliminates the potential for noise generation.  
I Water Connections—3⁄4" NPT factory installed true dielectric fittings.  
Extends water heater life and eases installation.  
I 2" Non-CFC Foam Insulation—Covers the sides and top of tank to save  
energy by retarding loss of heat. Also increases jacket rigidity.  
(The TW4-65S-65B-3N has 1" of foam insulation.)  
I Electronic Gas Control Valve—The integrated, immersion gas control valve  
offers more 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 display to aid in start-up and diagnostics.  
I Brass Drain Valve.  
I T&P Relief Valve included  
I Stainless Steel Flue baffle—Designed to maximize the amount of heat  
absorbed in the lower portion of tank. Reduces air movement in the heater  
during standby periods to retard heat loss up the flue.  
TW4-65S-65B-3N  
I Design certified by CSA International (formerly AGA and CGA).  
6-Year Limited Warranty on Component Parts / 6 or 10-Year Limited Tank Warranties.
