Energy Saver Gas Water Heater System

The Combi1™TTW®FVIR Defender Safety System®Models Feature
(50T model, only):

dvanced ScreenLok

■ A

arrestor is designed to prevent ignition of flammable vapor outside of the
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 Combi1™TTW®Models Feature

■ Heat Exchanger—Single Wall 1

steel coil.

■ Supply and Return Connections—1" NPT female connections are located

on the front for space heating supply and return.

■ 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.

■ Power

ful Blower Motor—

for a considerably longer operational life.

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

(Maximum equivalent vent lengths on reverse side).

corrosion for long trouble-free service.

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