Light Duty Commercial Energy Saver Gas

Through-The-WallWater Heaters

 

The TTW4 Models Feature:

 

Power Vented Heater—Designedfor 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—Ourdesign 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—Eliminatesthe 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—Horizontaland vertical venting up to 60

 

equivalent feet for 3" pipe, and up to 90 equivalent feet for 4" pipe. See

 

reverse side for specifics.

 

Vitraglas® Lining—BradfordWhite water heater tanks are protected from the

 

corrosive effects of hot water by a ceramic porcelain-likecoating. The

 

exclusive high silica ceramic lining provides a tough interior surface for our

 

water heater tank.

 

More precise temperature control—withan adjustable temperature up to

 

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

 

Steel Tank—Heavygauge steel automatically formed, rolled and welded to

 

assure a continuous seam for glass lining.

 

Side connections—Sidetappings allow easy connection for space heating

 

applications.

 

Protective magnesium rod—Providesadded protection against corrosion

 

for long trouble-freeservice.

 

Factory installed Hydrojet® Total PerformanceSystem—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.

 

Factory installed Heat Traps—Designincorporates a flexible disk that

 

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—Coversthe sides and top of tank to save

 

energy by retarding loss of heat. Also increases jacket rigidity.

 

(The TW4-65S-65B-3Nhas 1" of foam insulation.)

 

Electronic Gas Control Valve—Theintegrated, 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-upand diagnostics.

 

Brass Drain Valve.

 

T&P Relief Valve included

 

Stainless Steel Flue baffle—Designedto maximize the amount of heat

 

absorbed in the lower portion of tank. Reduces air movement in the heater

TW4-65S-65B-3N

during standby periods to retard heat loss up the flue.

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