(50T model, only):

■ Advanced ScreenLok

rrestor is designed to prevent ignition of flammable vapor outside of the

a
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 vapor burn 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.

■ Pedestal Base—Rugged and durable base allows easy transport and

positioning, and provides corrosion resistant contact with floor.

All Combi2™TTW®Models Feature

■ Heat Exchanger—Double wall 1

ensures separation of potable water and heating fluid.

■ Low Heat Exchanger Head Loss—Up to 10 GPM flow, with less than 5 ft.

of head loss. Greatly reduces the required pump size for heat exchange.

■ Factory installed Hydrojet

inlet sediment reducing device helps prevent sediment build up in tank.
Increases first hour delivery and minimizing temperature build up in tank.

■ Vitraglas

®

Lined Tank—Bradford White tanks are protected from the

corrosive effects of hot water by an exclusive ceramic porcelain-like coating.

■ Electronic Gas Control Valve—The integrated, immersion gas control valve

offers precise temperature control for higher first hour delivery and also
allows water temperature adjustment without removing the cover. Control is
equipped with an LED display to aid in start-up and diagnostics.

■ Spark to Pilot Ignition System—Eliminates the constant burning pilot used

on other water heaters.

■ 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.

■ Horizontal and Vertical Venting—With 3" or 4" PVC, ABS OR CPVC

(Maximum equivalent vent length on r

■ Thermostatic Mixing Valve—Supplied to help prevent injury due to

scalding.

■ Two Protective Aluminum Anode Rods—Provide added protection against

corrosion for long trouble-free service.

■ 2" Non-CFC Foam Insulation—Surrounds the tank surface, saving energy

by retarding loss of heat.

General

All gas water heaters are certified at 300 PSI test pressure (2068 kPa) and 150 PSI working pressure (1034 kPa). All potable water and heat exchanger
connections are 3⁄4" NPT (19mm) on 11" (203mm) centers. All gas connections 1⁄2" (13mm).

All models design certified by CSA International (formerly AGA/CGA), ANSI Z-21.10.1 and or 10.3 and peak performance rated.

Dimensions and specifications subject to change without notice in accordance with our policy of continuous product improvement.

Suitable for Water (Potable) Heating and Space Heating.

Toxic chemicals, such as those used for boiler treatment, shall NEVER be introduced into the potable water side. The potable side of this unit may NEVER
be connected to any existing heating system or component(s) previously used with a non-potable water heating appliance. The heat exchanger side of the
unit may be used in space heating applications.
