RISKS DURING OPERATION
Scalding Risk
This water heater can make water hot
enough to cause severe burns instantly, resul ng in severe injury or death.
• Feel water before bathing or
showering
• To reduce the risk of scalding, install
Thermosta c Mixing Valves (tempera- ture limi ng valves) at each point- of-use. These valves automa cally mix hot and cold water to limit the temperature at the tap. Mixing valves are available from Lowe’s®. Follow manufacturer’s instruc ons for instal- la on and adjustment of the valves.
• The thermostat(s) on this water
heater have been factory set to approximately 120°F to reduce the risk of scalding. Higher temperatures increase the risk of scalding, but even at 120°F, hot water can scald. If you choose a higher temperature, Thermosta c Mixing Valves located at each point-of-use are par cularly important to help avoid scalding.
Temperature Time to Produce a Serious Burn
120°F (49°C) More than 5 minutes
125°F (52°C) 1½ to 2 minutes
130°F (54°C) About 30 seconds
135°F (57°C) About 10 seconds
140°F (60°C) Less than 5 seconds
145°F (63°C) Less than 3 seconds
150°F (66°C) About 1½ seconds
155°F (68°C) About 1 second
For informa on about changing the factory thermostat se ng(s), refer to the “Adjus ng Temperature” sec on in this manual (see page 15, step 10).
Even if you set the water heater thermostat(s) to a low se ng, higher temperatures may occur in certain circumstances:
• In some cases, repeated small draws of water can cause the hot and cold water in the tank to “stack” in lay­ers. If this happens, the water can be as much as thirty degrees ho er than the thermostat se ng. This temperature varia on is the result of your usage pa ern and is not a malfunc on.
• Water temperature will be ho er if someone adjusted the thermostat(s) to a higher se ng.
• Problems with the thermostat(s), or other malfunc ons may result in higher than expected water tempera­tures.
• If the water heater is in a hot envi­ronment, the water in the tank can become as hot as the surrounding air, regardless of the thermostat se ng.
• If the water supplied to the water heater is pre-heated (for example, by a solar system) the temperature in the tank may be higher than the water heater’s thermostat se ng.
To reduce the risk of unusually hot water reaching the fi xtures in the house, install Thermosta c Mixing Valves at each point-of-use.
If anyone in your home is at par cular risk of scalding (for example, the elder­ly, children, or people with disabili es) or if there is a local code or state law
4 • Residen al Electric Water Heater Use and Care Guide
requiring a certain water temperature at the hot water tap, then these precau­ ons are par cularly important.
According to a na onal standard American Society of San ary Engineer- ing (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. A higher temperature se ng allows the tank to provide much more hot water and can help provide proper water temperatures for appliances such as dishwashers and washing machines. Higher tank temperatures (140°F) also kill bacteria that cause a condi­ on known as “smelly water” and can reduce the levels of bacteria that cause water-borne diseases.
Water Contamina on Risk
Do not use chemicals that could con­taminate the potable water supply. Do not use piping that has been treated with chromates, boiler seal, or other chemicals.
Fire Risk To reduce the risk of a re that could destroy your home and seriously
injure or kill people:
• Do not store things that can burn easily such as paper or clothes next to the water heater.
• Be sure the junc on box cover and the access door covers are in place. These covers keep debris from enter­ing and poten ally being ignited,
and help keep any internal fi res from spreading.
• Keep the water heater from becom­ing wet. Immediately shut the water heater off and have it inspected by a qualifi ed person if you fi nd that the wiring, thermostat(s) or surrounding insula on have been exposed to wa- ter in any way (e.g., leaks from plumb­ing, leaks from the water heater itself can damage property and could cause a fi re risk). If the water heater is subjected to fl ood condi ons or the thermostat(s) have been submerged in water, the en re water heater must be replaced.
• Make electrical connec ons properly, according to the instruc ons on page
14. Use 10 gauge solid copper wire. Use a UL listed or CSA approved strain relief. Connect ground wire to green ground screw.
Explosion Risk
High temperatures and pressures in the water
heater tank can cause an explosion resul ng in property damage, serious injury or death. A new Tem­perature and Pressure (T&P) Relief Valve is included with your water heater to reduce risk of explosion by discharg­ing hot water. Addi onal temperature and pressure protec ve equipment may be required by local codes.
A na onally recognized tes ng labo- ratory maintains periodic inspec on of the valve produc on process and cerfi es that it meets the requirements for Relief Valves for Hot Water Supply Systems, ANSI Z21.22. The T&P Relief Valve’s relief pressure must not exceed the working pressure ra ng of the wa- ter heater as stated on the ra ng plate.
Maintain the T&P Relief Valve properly. Follow the maintenance instruc ons provided by the manufacturer of the T&P Relief Valve (label a ached to T&P Relief Valve) and the procedure that starts on page 24.
An explosion could occur if the T&P Re­lief Valve or discharge pipe is blocked. Do not cap or plug the T&P Relief Valve
or discharge pipe.
Fire and Explosion Risk if Hot Water is Not Used for Two Weeks or More
CAUTION! Hydrogen gas builds up in a hot water system when it is not used for a long period (two weeks or more). Hydrogen gas is extremely ammable. If the hot water system has not been used for two weeks or more, open a hot water faucet for several minutes at the kitchen sink before using any electrical appliances con­nected to the hot water system. Do not smoke or have an open fl ame or other igni on source near the faucet while it is open.

installa on:
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. Install any devices you need to comply with codes and assure that your new water heater performs at its best. Check with your local plumbing offi cial for more informa on.
Water pressure
We recommend checking your home’s water pressure with a pressure gauge (fi gure 4). Most codes allow a maximum incoming water pressure of 80 psi. We recommend a working pres­sure no higher than 50-60 psi.
HOW: Purchase an inexpensive water pressure gauge from Lowe’s®. Connect the Water Pressure Gauge to an out­side faucet and measure the maximum water pressure experienced through­out the day (highest water pressures
Figure 4 - Use a Water Pressure Gauge to make sure your home’s water pressure is not too high.
o en occur at night).
To limit your home’s water pressure: Locate your home’s Pressure Reduc­ing Valve (PRV) on the main incoming (cold) water supply line and adjust the water pressure control to between 50 and 60 psi. If your home does not have a Pressure Reducing Valve, install a PRV on the home’s main water supply line and set it to between 50 and 60 psi. Pressure Reducing Valves are avail­able at Lowe’s®.
BACKGROUND: Over the years, many u li es have increased water sup- ply pressures so they can serve more homes. In some homes today, pres­sures exceed 100 psi. High water pressures can damage water heaters, causing premature leaks. If you have replaced toilet valves, had a water heater leak, or had to repair applianc­es connected to the plumbing system, pay par cular a en on to your home’s water pressure. When purshasing a PRV, make sure the PRV has a built-in bypass.
Water pressure
increase caused by
thermal expansion
Verify that you have a properly sized Thermal Expansion Tank (fi gure 5). We recommend installing an expansion tank if your home does not have one. Codes require a properly pressurized, properly sized Thermal Expansion Tank in almost all homes. (See photo on inside front cover.)
Figure 5 - A Thermal Expansion Tank helps protect the home’s plumbing system from pres­sure spikes.
HOW: Connect the Thermal Expansion Tank (available from 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.
BACKGROUND: Water expands when heated, and the increased volume of water must have a place to go, or

thermal expansion will cause large increases in water pressure (despite the use of a Pressure Reducing Valve on the home’s main water supply line). The Safe Drinking Water Act of 1974 requires the use of backfl ow preventers and check valves to restrict water from your home reentering the public water system. Backfl ow preventers are o en installed in water meters and may not be readily visible. As a result, most all plumbing systems today are now “closed,” and almost all homes now need a Thermal Expan­sion Tank.
A Thermal Expansion Tank is a prac - cal and inexpensive way to help avoid damage to the water heater, washing machine, dishwasher, ice maker and even toilet valves. If your toilet oc­casionally runs for no apparent reason (usually briefl y at night), that may be due to thermal expansion increasing the water pressure temporarily.
Water pipe and tank leaks
Leaks from plumbing pipes or from the water heater itself can damage property and could cause a fi re risk.
• Install an automa c leak detec on and shutoff device (available from Lowe’s®). These devices can detect water leaks and can shut off the water heater’s water supply if a leak occurs.
Figure 6 - A suitable drain pan piped to an adequate drain can help protect fl ooring from leaks and drips.
heater in a drain pan that is piped to an adequate drain. The drain pan must be at least two inches wider than the diameter of the water heater. Install the drain pan so the water level would be limited to a maximum depth of 1-3/4”.
Water tempera-
ture regula on
Install Thermosta c Mixing Valves (fi g- ure 7) to regulate the temperature of the water supplied to each point-of­use (for example, kitchen sink, bath­room sink, bath, shower). Consult the valve manufacturer’s instruc ons or a qualifi ed person.
WARNING! Even if the water heater
thermostat is set to a rela vely low temperature, hot water can scald. Install Thermosta c Mixing Valves at each point-of-use to reduce the risk of scalding (see page 4).
BACKGROUND: A Thermosta c Mix-
ing Valve, installed at each point­of-use, mixes hot water from the water heater with cold water to more precisely regulate the temperature of hot water supplied to fi xtures. If you aren’t sure if your plumbing system is equipped with properly installed and adjusted Thermosta c Mixing Valves at each point where hot water is used, contact a qualifi ed person for more informa on.
• Install a suitable drain pan (available from Lowe’s®) under the water heat­er (fi gure 6) to catch condensa on or leaks in the piping connec ons or tank. Most codes require and we recommend installing the water

Before installing your water heater, ensure that:
The water heater will be:
1
• Installed indoors close to the center of the plumbing
system.
• In a suitable drain pan piped to an adequate fl oor drain or external to the building (See page 8, fi gure 6).
• In an area that will not freeze
• In an area that is suitable for install­ing the water heater ver cally
The loca on has adequate

weight of a full water heater.
Your area is not prone to
4
earthquakes. If it is, use special straps as required by
local building codes.
Vehicle Stop
Drain Pan
In a garage, install a vehicle stop to avoid water heater damage.
Avoid loca ons such as a cs,
6
upper fl oors, or where a leak
might damage the structure or furnishings. Due to the normal corrosive ac on of water, the tank will eventually leak. To minimize property damage from leaks, inspect and maintain your water heater in accor­dance with this manual’s instruc ons. Install a suitable drain pan under the water heater piped to an adequate drain. Inspect the drain pan, pipes, and surrounding area regularly and fi x any leaks found. Drain pans are available from Lowe’s®. Leaks are frequently in the plumbing system itself and not the water heater.
