Bradford-White TTW4 User Manual

Light Duty Commercial Energy Saver Gas

Through-The-Wall Water Heaters

The TTW4 Models Feature:

■ 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.

■ 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.

■ 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).

■ 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

TW4-65S-65B-3N

reverse side for specifics.

■ Vitraglas

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.

■ More precise temperature control—with an adjustable temperature up to

180° F. Not recommended for 180° F sanitizing.

■ Steel Tank—Heavy gauge steel automatically formed, rolled and welded to

assure a continuous seam for glass lining.

■ Side connections—Side tappings allow easy connection for space heating

applications.

■ Protective magnesium rod—Provides added protection against corrosion

for long trouble-free service.

■ Factory installed Hydrojet

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.

■ Factory installed Heat T

reduces heat loss in piping and eliminates the potential for noise generation.

■ Water Connections—3⁄4" NPT factory installed true dielectric fittings.

Extends water heater life and eases installation.

■ 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.)

■ 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 star

■ Brass Drain Valve.

■ T&P Relief Valve included

■ Stainless Steel Flue baf

absorbed in the lower portion of tank. Reduces air movement in the heater
during standby periods to retard heat loss up the flue.

■ Design certified by CSA International (formerly AGA and CGA).
