4 FEATURES & BENEFITS BLUE DIAMOND GLASS COATING Provides superior corrosion resistance compared to industry-standard glasslining. ENHANCED-FLOW BRASS DRAIN VALVE Our residential water heaters have a solid brass, tamper resistant, enhancedflow, ball type, drain valve. Uses a standard female hose fitting that allows for fast and easy draining during maintenance. Designed for easy operation, this valve includes an integral screwdriver slot that features a 1/4 turn (open/close) radius, which not only permits full straightthrough water flow but also a quick and positive shut off. SELF-POWERED ELECTRONIC GAS VALVE A. O. Smith gas water heaters are equipped with a self-powered electronic gas valve with intelligent control logic. The gas valve has an internal microprocessor that provides enhanced operating parameters and tighter differentials for precise sensing and faster heating response to optimize performance. The self-powered electronic gas valve uses a thermopile to generate the power needed to operate the electronic gas control without requiring an external power source It also incorporates an LED Status Indicator that monitors system operation and service diagnostics. HEAT TRAP NIPPLES Helps mitigate standby heat loss. Factoryinstalled for faster installation. SELF-CLEANING DIP TUBES Helps reduce lime and sediment buildup and maximizes hot water output. Made from long-lasting PEX cross-linked polymer. T&P RELIEF VALVE ENERGY STAR A. O. Smith offers a variety of models that are ENERGY STAR qualified. Learn more at CSA Certified and ASME Rated. GREEN CHOICE GAS BURNER COREGARD ANODE ROD Our anode rods have a stainless steel core that extends the life of the anode rod allowing superior tank protection far longer than standard anode rods. Patented eco-friendly burner design reduces NOx emissions up to 33% and complies with low NOx emissions of less than 40 ng/j. Enhanced Ultra-Low NOx burner complies with SCAQMD Rule 1121 and other air quality management districts with requirements for NOx emissions of less than 10 ng/j. NAECA III COMPLIANT Complies with the Federal Energy Conservation Standards effective April 16, 2015, in accordance with the Energy Policy and Conservation Act (EPCA), as amended. 1

5 RESIDENTIAL WATER HEATER SELECTION GUIDE TANK TYPE SIZING To select the right A. O. Smith water heater for your home, you need to consider the size of your family and other factors that contribute to your First Rating (FHR) Requirement. The charts below provides suggested A. O. Smith residential water heater selection guidelines for several family sizes. FAMILY SIZE FIRST HOUR RATING REQUIREMENTS 2 PEOPLE GALLONS 3 PEOPLE GALLONS 4 PEOPLE GALLONS 5 PEOPLE GALLONS 6 PEOPLE GALLONS 7 OR MORE PEOPLE 100 OR MORE GALLONS 1. Determine whether your family is low demand or high demand. You should consider your family to be high demand if... There are more than two full baths in the home. There are (or will be) teenagers living in the home. It s a fact: teenagers use more hot water for showering and washing clothes. You have an oversize whirlpool bath or other large tub. As a rule of thumb, the water heater tank capacity should be 100% of the bathtub capacity (example: 75-gallon tub / 75-gallon water heater). 2. Locate your family size and determine the first hour rating requirement for your family. If you decide your family is high demand, consider moving up to the next first hour rating level. 3. Consult the heater options on the following pages for an A. O. Smith residential water heater with a first hour rating that meets your requirements. TANKLESS SIZING Average Ground Water Temperature 2 SOUTHERN ZONE Average Ground Water Temperature: 62 F to 77 F CENTRAL ZONE Average Ground Water Temperature: 52 F to 61 F NORTHERN ZONE Average Ground Water Temperature: 37 F to 51 F Remember, these are general recommendations. Your A. O. Smith Water Heater Specialist can review your family s needs in even greater detail to make sure the model you choose will always provide enough hot water to meet the demand. TANKLESS MODELS GROUND WATER TEMPERATURE FACTOR The temperature of incoming ground water (cold water inlet temperature) varies greatly throughout the U.S. and also fluctuates with the changing of the seasons. The temperature of water as it enters the water heater will determine the amount of temperature rise required to achieve the desired hot water outlet temperature (120 F is recommended). The best way to measure your incoming ground water temperature is to use a thermometer to measure cold water temperature during the coldest season of the year. To simplify the process, use this map to determine whether your installation location is in the Southern Zone, Central Zone or Northern Zone. PEAK HOT WATER DEMAND The next step is to determine how many gallons per minute of hot water will be required during the busiest usage period ( peak demand ). Consider all appliances and fixtures that use hot water, including lavatory faucets, kitchen faucets, washing machines, dishwashers, showers and bathtubs. Be sure to determine how many appliances and fixtures will be used at the same time ( peak demand ).

6 GUIDING YOU THROUGH THE NAECA III TRANSITION The U.S. Department of Energy (DOE) regulates minimum energy efficiency requirements for all brands of water heaters. A new update to the rules for increasing minimum energy efficiency is in effect as of April 16, AT A. O. SMITH, WE VE PREPARED OUR LINE OF RESIDENTIAL WATER HEATERS TO MEET THE STANDARDS. BUT AS SOMEONE IN THE BUILDING COMMUNITY, YOU NEED TO UNDERSTAND HOW THESE CHANGES IMPACT YOU AS WELL. These design changes require that most residential water heaters under 55 gallons of capacity produced after April 16, 2015 be larger in size. Therefore, they will require more installation space in both single-family and multi-family housing. Most water heaters under 55 gallons are 2 larger in height and diameter. Units over 55 gallons will require even more drastic technology changes. WATER HEATER REPLACEMENT ISSUES? WE HAVE SOLUTIONS. ELECTRIC GAS LESS THAN 55 GALLON MORE THAN 55 GALLON LESS THAN 55 GALLON MORE THAN 55 GALLON WILL THE NEW LARGER DESIGN FIT? IF NOT, YOU HAVE TWO OPTIONS. OPTION 1: Use a smaller heater to match the current footprint of your existing heater. You might consider adding a mixing valve on the water heater to increase delivery capacity. OPTION 2: Upgrade to a smaller more efficient tankless unit. THE TECHNOLOGY FOR UNITS OVER 55 GALLONS HAS CHANGED. OPTION 1: Upgrade to one of A. O. Smith s High Efficiency Options such as tankless or Vertex. OPTION 2: Replace your obsolete model with 2 smaller gas heaters. ( Example: two 40-gallon gas units in the place of one 75-gallon gas unit). WILL THE NEW LARGER DESIGN FIT? IF NOT, SEE BELOW. OPTION 1: Use a smaller heater to match the current footprint of your existing heater. You might consider adding a mixing valve on the water heater to increase delivery capacity. THE TECHNOLOGY FOR UNITS OVER 55 GALLONS HAS CHANGED. OPTION 1: Upgrade to A. O. Smith s Voltex Hybrid Electric Heat Pump water heater which is 2.5x more efficient as a standard electric. OPTION 2: Replace your obsolete model with 2 smaller electric heaters ( Example: Two 40-gallon electrics in the place of one 80-gallon electric). TO LEARN MORE, VISIT HOTWATER.COM/NAECA 3
