Read and follow all safety messages and instruc ons in this manual. This is the safety alert symbol. It is used to alert you to poten al physical injury hazards. Obey all safety messages that follow this symbol to avoid possible property damage, serious injury or death. Do not remove any permanent instruc ons, labels, or the data plate from either the outside of the water heater or on the inside of the access panels. Keep this manual near the water heater.

SAFETY IMPORTANT SAFETY INFORMATION T o reduce the risk of property damage, serious injury or death, read and follow the precau ons below, all labels on the water heater, and the safety messages and instruc ons throughout this manual.
PAGE 5
According to a na onal standard: American Society of Sanitary Engineering (ASSE 1070) and most local plumbing codes, the water heater’s thermostat should not be used as the sole means to regulate water temperature and avoid scalds. Properly adjusted Thermosta c Mixing Valves installed at each point-of-use allow you to set the tank temperature to a higher se ng without increasing risk of scalds.
PAGE 6
GETTING STARTED Review all of the instruc ons before you begin work. If you aren’t sure that you can safely and properly do this work yourself, call your Lowe’s® store to arrange for Professional Installa on (you may also call a qualiﬁed person of your choice, such as a licensed plumber or electrician, to have the work done). Improper installa on can damage the water heater, your home and other property, and can present risks of serious injury or death.

INSTALLATION Step 1: ✓ Verify that your home is equipped and up-to-date for proper opera on Installing a new water heater is the perfect me to examine your home’s plumbing system and make sure the system is up to current code standards. There have likely been plumbing code changes since the old water heater was installed. We recommend installing the following accessories and any other needed changes to bring your home up to the latest code requirements. Use the checklist below and inspect your home.
PAGE 8
INSTALLATION INSTALLATION HOW: Connect the Thermal Expansion Tank (available at Lowe’s®) to the cold water supply line near the water heater. The expansion tank contains a bladder and an air charge. To work properly, the Thermal Expansion Tank must be sized according to the water heater’s tank capacity and pressurized to match the home’s incoming water pressure. Refer to the installa on instruc ons provided with the Thermal Expansion Tank for installa on details.
PAGE 9
INSTALLATION 5 Verify that the loca on is appropriate The water heater will be: • Installed indoors close to the center of the plumbing system. • In a suitable drain pan piped to an adequate floor drain or external to the building (Figure 6 on page 8). • In an area that will not freeze • In an area that is suitable for installing the water heater vertically The loca on has adequate space (clearances) for periodic servicing.
PAGE 10
INSTALLATION Figure 9 - Mounting for Drywall Moun ng - Masonry Wall (Solid Wall): The selected wall or cabinet must be capable of suppor ng double the weight of the unit when completely full of water (up to 150lbs). The installa on area must provide adequate clearances for removal of the front panel and servicing the unit. Drill two 13/32” holes in the masonry wall. NOTE: The holes MUST be level and at least 3-1/2” deep. . Insert the masonry wall anchors into the drilled holes.
PAGE 11
INSTALLATION Discharge Pipe (no more than) 6 “ (15.2cm) Step 5: Install shutoﬀ and tempering valves If one is not already installed, install a manual shutoﬀ valve in the cold water line that supplies the water heater. Install the shutoﬀ valve near the water heater so that it is readily accessible. Only use valves that are compa ble with potable water. Use only full-ﬂow ball or gate valves. Other types of valves may cause excessive restric on to the water ﬂow.
PAGE 12
INSTALLATION NOTICE: Most water heater models contain energy saving heat traps in the inlet and outlet connec ons. Do not remove the heat traps. IF YOU HAVE COPPER PIPES: If your home has copper water pipes, you can solder the water pipe connec ons or use compression ﬁ ngs which don’t require soldering. Compression ﬁ ngs are easier to install than soldering pipe. Check with local plumbing oﬃcials to determine what types of pipe materials are suitable for your loca on. Do not use lead-based solder.
PAGE 13
INSTALLATION Step 8: (6 Gal. Models) Make electrical connec ons (2.5 and 4 gallon models have a power cord, plug into an outlet) If Dry Firing occurs, replace the heating element according to the instrucons on page 20. WARNING! Working on an energized circuit can result in severe injury or death from electrical shock. NOTICE: Do not turn electrical power on unless you are sure all of the air is out of the tank and the tank is completely full of water.
PAGE 14
INSTALLATION Step 9: Adjus ng the Temperature With the installa on steps completed, you may adjust the water heater’s temperature se ng if desired. Set the thermostat(s) to desired temperature. The thermostat on this water heater has been factory set to approximately 105°F to reduce the risk of scald injury. You may wish to set a higher temperature to provide more hot water capacity, and to reduce bacterial growth.
PAGE 15
INSTALLATION Step 10: Opera on The water heater is now ready for normal opera on. To keep your water heater working safely and eﬃciently and extend its life, perform maintenance according to the schedule on page 19. INSTALLATION Vaca on To save energy, lower the temperature se ng on the thermostat(s) if you plan to be gone for an extended me.

TROUBLESHOOTING WARNING! Working near an energized circuit can result in severe injury or death from electrical shock. WARNING! When you are ﬁnished, be sure all covers are secured to reduce the risk of ﬁre and electric shock.
PAGE 17
TROUBLESHOOTING WARNING! Be sure all covers are secured to reduce the risk of ﬁre and electric shock. WARNING! Because of the increased risk from scalding, if you set the water heater’s thermostat(s) higher than 120°F, Thermosta c Mixing Valves at each point-of-use are par cularly important (page 4).
PAGE 18
TROUBLESHOOTING Temperature Too High If the water temperature is too hot: • Install or adjust the Thermostatic Mixing Valves for each point-of-use (see manufacturer’s instructions), or • Adjust the temperature by turning the dial counter-clockwise. TROUBLESHOOTING A nonfunc oning thermostat or a shorted hea ng element can cause extremely hot water.
PAGE 19
MAINTENANCE Rou ne maintenance will help your water heater last longer and work be er. If you can’t perform these rou ne maintenance tasks yourself, contact a qualiﬁed person. A er the ﬁrst six months, drain and ﬂush the water heater and inspect the anode rod. Depending on the hardness of your water, repeat this process at least annually, or more frequently if needed. From me to me, you may need to replace a hea ng element or a thermostat. All three maintenance tasks are described below.
PAGE 20
MAINTENANCE Inspect the anode rod more frequently, replacing the anode rod as needed. Obtain a new anode rod by contac ng our Technical Assistance Hotline (reference contact informa on on cover). NOTE: Anode rods are a consumable item and are not covered under warranty. If the sediment was present when the tank was drained, ﬂush the tank by opening the cold water supply valve and le ng the water run un l no more sediment drains from the tank.
PAGE 21
MAINTENANCE Check the newly installed element for leaks. If a leak is present, ghten the element un l the leak stops. If you cannot stop the leak, drain the tank and remove the element. Inspect the gasket for damage. If the gasket is damaged, replace the gasket and re-install the element. 9 Access Panel Figure 30 - Junction Box and Access Panel Using a 10mm nut driver, remove the ﬁve (5) nuts a aching the element to the tank and extract the element from the tank.
