Description for Bradford White M-I-403S6FBN

PLEASE NOTE: This water heater cannot be sold to residents of certain southern California zip codes due to Air Quality Regulations. To view a list of zip codes where this heater cannot be installed, click here.

This Bradford White water heater utilizes a draft diverter and is atmospherically vented. It is perfect for many standard water heating applications.

Features:

  • Bradford White ICON System - Intelligent gas control with proven millivolt powered technology and built-in piezo igniter. A standard, off the shelf thermopile converts heat energy from the pilot flame into electrical energy to operate the gas valve and microprocessor. No need for external electricity.
    • Enhanced Performance - Proprietary algorithms provide enhanced First Hour Delivery ratings and tighter temperature differentials.
    • Advanced Temperature Control System - Microprocessor constantly monitors and controls burner operation to maintain consistent and accurate water temperature levels.
    • Intelligent Diagnostics - An exclusive green LED light prompts the installer during start-up and provides ten different diagnostic codes to assist in troubleshooting.
    • Pilot On Indication - Flashing green LED provides positive indication that pilot is on.
    • Separate Immersed Thermowell - 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.
  • Advanced ScreenLok® Technology Flame Arrestor Design - Flame arrestor is designed to prevent ignition of flammable vapor outside of the water heater.
  • Resettable Thermal Switch - 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.
  • Maintenance Free - No regular cleaning of air inlet openings or flame arrestor is required under normal conditions.
  • Sight Window - Offers a view into the combustion chamber to observe the operation of the pilot and burner.
  • Factory Installed Hydrojet® Total Performance System - Cold water inlet sediment reducing device helps prevent sediment build up in tank. Increases first hour delivery of hot water while minimizing temperature build up in tank.
  • Vitraglas® Lining - Bradford White tanks are lined with a exclusively engineered enamel formula that provides superior 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 1600ºF.
  • 1" Non-CFC Foam Insulation - Covers the sides and top of tank, reducing the amount of heat loss. This results in less energy consumption, improved operation efficiencies and jacket rigidity.
  • Pedestal Base.
  • Water Connections -3/4" NPT factory installed true dielectric fittings.
  • Factory Installed Heat Traps.
  • Protective Magnesium Anode Rod.
  • 3x4 "Snap Lock" Draft Diverter - Allows either 3" or 4" vent connections with inputs of 40,000 BTU/Hr or less. Over 40,000 BTU/Hr. has the 4" "Snap Lock" Draft Diverter.
  • T&P Relief Valve - Included.
  • Brass Drain Valve - Tamper proof design

PLEASE NOTE: The product weighs 128 lbs. and may require the use of a
lift gate.
If you do require a lift gate at your delivery, you'll have the option to add this FREE of charge when you checkout.

Normally I perform research before buying products. In this case the research followed the purchase. I was pleased to learn Bradford White WH are considered #1. Similar tanks from Whirlpool and Kenmore lack the better magnesium anode. Model MI403S6FBN is a tradition atmospheric vented tank. The model is 79% efficient but I can turn down the water temperature down when leaving the house to work. The next step up in efficiency is a power vent model. Power vents mean motors to go bad and require an electric plug. Simple is always best for longevity.

The burner controls are from Honeywell and are reported to be 1st rank. A skilled handyman installed the tank with no problems.

Great heater

By DementedDad

from Texas

Verified Buyer

Comments about 40 Gallon - 40,000 BTU Defender Safety System Atmospheric Vent Energy Saver Residential Water Heater (Nat Gas):

I ordered two of these and did a parallel installation (house has 3.5 baths and a whirlpool tub. The heaters were easy to connect and the Honeywell gas valve make it easy to light the pilot and get things going. They both started right up without any fuss and the burner flames look great. It took only about 45 minutes to go from full cold to the B setting. That turned out to be too hot for us so I moved in back to between A and B. The heaters came with the pressure relief valves in the package. It was great to find these at Pex since Bradford White is not usually available at retail.

Fantastic product

By Rob the remodeler

from Fort Worth, TX

Verified Buyer

Comments about 40 Gallon - 38,000 BTU Defender Safety System Atmospheric Vent Energy Saver Residential Water Heater (LP Gas):

I replaced a whirlpool heater that we had for about 7 years. I had never heard of Bradford White before I bought this unit. PexSupply had a great price and delivery was smooth. The installation was a super easy. The quality of construction and the components on it are solid. Nothing cheap on it or about it. When it's running you don't even know it. The recovery time is also great. We have 4 in our house and this 40gallon tank seems to always be enough water. I am very hard to please and NEVER leave product reviews unless I am 100% satisfied. You will not regret getting this unit or any made by this manufacture.

Comments about 40 Gallon - 40,000 BTU Defender Safety System Atmospheric Vent Energy Saver Residential Water Heater (Nat Gas):

We bought it to replace equipment damaged during hurricane Sandy, it works great. We were able to raise the equipment on blocks without any extra work because it was short enough. Pex Supply was professional and the delivery was prompt.

Buying my second one

By just george

from Rochester, New York

Comments about 40 Gallon - 40,000 BTU Defender Safety System Atmospheric Vent Energy Saver Residential Water Heater (Nat Gas):

This is the ideal unit for a household of 2 or 3 people who use a limited amount of water. This wouldn't be a wise choice for a big family.
My first one has lasted 8 years. It probably would go longer if I replace the anode rod. It's never been replaced.

    Q:

    Do you need to turn the vent facing down after exiting the building?
    Asked on 6/5/2014 by the whistler

    1 answer

    • CUSTOMER CARE

      A:

      This atmospheric vent water heater must be connected to a lined masonry chimney or venting system. It is not approved for horizontal venting. If venting through the roof of the building use of a vent cap will protect the exhaust flue from the elements.

    • CUSTOMER CARE

      A:

      Both units are 40-gallons, but keep in mind that this Bradford White model uses atmospheric (not power) venting. Bradford White's M-1-TW-40S6FBN is their closet alternative to the A.O. Smith GPSH-40.
