maximum wattage/voltage = amperage.
Example: a 4500 watt/240 volt heater will draw
4500/240 = 18.75 amps.

These water heaters meet or exceed the performance standards established under ASHRAE Standard 90.1b 1992.

Features:

Bradford White is ISO registered to the 9001-1994 standard.

 1" Non-CFC foam insulation - surrounds the tank surface, saving energy by retarding loss of heat.
 Factory installed nipples - for longer water heater life. Easier installation. No special dielectric fittings to buy.
 Fully automatic controls - fast acting surface-mount thermostats for automatic temperature control. Factory installed sensitive manual reset energy cutoff for safety to prevent overheating. (Maximum thermostat setting 160oF.)
 Direct heat transfer with immersed elements - apply heat directly and efficiently to the water. Screw-In style.
 Vitraglas® lining - Bradford White water heater tanks are protected from the corrosive effects of hot water by an exclusive ceramic porcelain-like coating. The Bradford White high silica Vitraglas� lining provides a tough interior surface for our hot water tanks.
 Terminal Block - factory installed in junction box on all models.
 Field Convertible - capable of being converted to single phase and/or simultaneous operation at the terminal block.
 Protective magnesium anode rod - provides added protection against corrosion for long trouble-free service.
 Factory installed Hydrojet� Total Performance System - 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.
 T&P relief valve - actory installed.
 Brass drain valve
 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.
