Commercial Gas Light Duty

High Input Direct Vent Water Heater

Features:

 

9001

Bradford White is ISO registered to the

S T A N D A R D

9001 standard.

1" Non-CFC foam insulation—surroundsthe tank surface, saving energy by retarding loss of heat.

Closed combustion—allair for combustion is taken directly from the outside. Theco-axialvent pipe (pipe inside a pipe) draws combustion air in through the outer pipe (6"), and exhausts the products of combustion through the inner pipe (4").

Co-axial—rotationalventing at top of unit.

No electrical power necessary.

Piezo igniter—forease of lighting the pilot.

Water Connections—3/4"NPT factory installed true dielectric fittings. Extends water heater life and eases installation.

Vitraglas® lined tank—BradfordWhite water heater tanks are protected from the corrosive effects of hot water by an exclusive ceramicporcelain-likecoating. The Bradford White high silica Vitraglas® lining provides a tough interior surface for our water heater tanks.

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.

Protective magnesium anode rod—provides added protection against corrosion for long trouble-free service.

Brass drain valve.

T&P relief valve—factoryinstalled.

Side Tappings—forspace heating purposes.

Fully automatic controls—automatictemperature selection at your fingertips.Built-inenergycut-offswitch prevents abnormally high water temperature for extra safety.Built-ingas pressure regulation. Fastacting thermostat starts heat recovery cycle sooner.

NSF construction available.

Optional vent kits—allowfor up to 8 foot max vertical and 8 foot max horizontal (2.4 meters)). All DH models must be terminated horizontally.

Three year limited warranty on steel tank—heavy gauge steel automatically formed, rolled and welded to assure a continuous seam for glass lining.

One year limited warranty on parts.

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