Bradford White Water Heaters RG275H6N

bock water heaters 51e

Intelligent gas control with proven millivolt powered technology and built-in piezo igniter
• Proprietary algorithms provide enhanced first hour delivery ratings and tighter temperature differentials
• Microprocessor constantly monitors and controls burner operation to maintain consistent and accurate water temperature levels
• An exclusive green LED light prompts the installer during start-up and provides ten different diagnostic codes to assist in troubleshooting
• Sight window offers a view into the combustion chamber to observe the operation of the pilot and burner
• An exclusively engineered enamel formula that provides superior tank protection from the highly corrosive effects of hot water, this formula (Vitraglas) is fused to the steel surface by firing at a temperature of over 1600 deg F
• Non-CFC foam covers the sides and top of the tank, reducing heat loss, this results in less energy consumption, improved efficiencies, and jacket rigidity
• Temperature and pressure relief valve installed
• Durable tamper proof design low restriction brass drain valve
• Protective magnesium anode rod
• Factory installed heat traps
• Factory installed hydrojet total performance system
• Advanced screenlok technology flame arrestor is designed to prevent ignition of flammable vapor outside of the water heater
• Flashing green LED provides positive indication that pilot is on
• High strength advanced polymer composite thermowell provides isolation between electric temperature sensor and surrounding water, no need to drain the tank when removing gas valve
• Pedestal base
• No regular cleaning of air inlet openings or flame arrestor is required under normal conditions
• 6 years limited tank and component parts warranty
• 3 x 4""snap lock" draft diverter
• Less than 40 ng/J NOx emissions
• Proven and reliable bimetallic switch prevents burner and pilot operation in case of ongoing flammable vapor burn inside of the combustion chamber or restricted air flow
  

  Bradford White Water Heaters RG250T6X

bock water heaters 33e

Single-wall full throat 1-1/2" diameter internal coil heat exchanger
• Factory installed aquastat on all models
• Factory installed temperature and pressure relief valve and brass drain valve
• Robust construction - inner tank is precision built from high quality steel and repetitive pressure testing assures the highest quality
• All steel construction with an environmentally-friendly powder coat finish providing a tough and attractive exterior
• Cobalt-enriched porcelain enamel glass lined tank and coil are highly resistant to aggressive water not susceptible to damage due to the presence of chloride in the water
• Ecomate insulation does not contribute to global warming
• Two magnesium anode rods - inhibit corrosion and maximize tank life. Electrolysis attacks the anode rods, not the tank
• Factory installed dielectric nipples on boiler connections - provides greater insulating protection
