WATER HEATER SAFETY
Your safety and the safety or others are very important.
We have provided many important safety messages in this manual and on your appliance. Always read and obey all safety messages.
This is the safety alert symbol. This symbol alerts you to potential hazards that can kill or hurt you and others. All safety messages will follow the safety alert symbol and either the word “DANGER” or “WARNING”. These words mean:
DANGER: indicates an imminently hazardous situation which, if not avoided, will result in death or injury.
WARNING: indicates a potentially hazardous situation which, if not avoided, could result in death or injury.
All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury, and tell you what can happen if the instructions are not followed.
IMPORTANT: Hydrogen gas is produced in a hot water system served by this heater that has not been used for a long period of time (2 weeks or more). Hydrogen is extremely fl ammable. To reduce the risk of injury under these conditions, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water system. When hydrogen is present, there will probably be an unusal sound such as air escaping through the pipe as the water begins to fl ow. There should be no smoking or open fl ame near the faucet at the time it is open.
The California Safe Drinking Water and Toxic Enforcement Act requires the Governor of California to publish a list of substances known to the State of California to cause cancer, birth defects, or other reproductive harm, and requires businesses to warn of potential exposure to such substances.

Location Requirements
Site location
Select a location near the center of the water piping system. It must be installed indoors and in a vertical position on a level surface, in an area where water leakage will not cause consequential damage.
NOTE: Local codes and requirements in your area may require the water heater to be installed such that the bottom element is elevated from the floor at least 18 inches.
The water heater should be located in an area not subject to freezing temperatures. Water heaters located in unconditioned spaces (i.e., attics, garages, base­ments, etc.) may require the water piping and drain piping to be insulated to protect against freezing. The drain and controls must be easily accessible for opera­tion and service.
Keep combustibles such as boxes, magazines, clothes, etc., away from the water heater area.
Do not use this water heater in conjunction with a spa or hot tub.
IMPORTANT: The water heater should be located in an area where leakage of the tank or connections will not result in damage to the area adjacent to the water heater or to lower floors of the structure. Due to the
normal corrosive action of the water, the tank will eventually leak after an extended period of time. Also, any external plumbing leak, including those from improper installation, may cause early failure of the water tank due to corrosion if not repaired. If the homeowner is uncomfortable with making the repair, a qualified person should be contacted. A suitable metal drain pan should be
installed under the water heater as shown below. This metal drain pan is to protect the property from damage which may occur from normal condensate formation on the tank or leaks in the tank and pipe connections. The metal drain pan must limit the water level to a maximum depth of 2-1/2 inches and be two inches wider than the heater and piped to an adequate drain. Locate the water heater near a suitable indoor drain. Outdoor drains are subject to freezing temperatures which can obstruct the drain line. The piping should be at least 3/4”ID and pitched for proper drainage.
Under no circumstance will the manufacturer or seller of this water heater be held liable for any water damage that is caused by your failure to follow these instructions.
NOTE: The water heater shall be located so it is not
subject to physical damage by moving vehicles or area flooding.

Water System Piping
Piping Installation
Piping, fi ttings, and valves should be installed according to the installation drawing (Figure 3). If the indoor in­stallation area is subject to freezing temperatures, the
water piping must be protected by insulation.
Water supply pressure should be around 50 to 60 psi and should not exceed 80 psi. If this occurs, a pressure
reducing valve should be installed in the cold water inlet line. This should be placed on the supply to the entire house in order to maintain equal hot and cold water pressures.
IMPORTANT: Heat cannot be applied to the water fi ttings
on the heater as they may contain nonmetallic parts. If solder connections are used, solder the pipe to the adapter before attaching the adapter to the hot and cold water fi ttings.
IMPORTANT: Always use a good grade of joint com-
pound and be certain that all fi ttings are drawn up tight.
1. Install the water piping and fitting as shown in Figure 3. Connect the cold water supply (3/4” NPT) to the fitting marked “Cold”. Connect the hot water supply (3/4” NPT) to the fitting marked “Hot”.
IMPORTANT: Some models may contain energy saving
heat traps to prevent the circulation of hot water within the pipes. Do not remove these inserts.
2. The Installation of dielectric unions in both the hot and cold water supply lines is recommended for ease of removing the water heater for service or replacement.
3. Some local codes may require, and the manufac­ turer of this water heater recommends, installing a mixing valve in the domestic hot water line as shown in Figure 4. These valves reduce the point-of-use temperature of the hot water by mixing cold and hot water and are readily available. Contact a licensed plumber or the local plumbing authority.
4. If installing the water heater in a closed water system, install a relief valve or expansion tank in the cold water line as specified under “Closed System/Thermal Expansion”.
5. Install a shut-off valve in the cold water inlet line. It should be located close to the water heater and be easily accessible. Know the location of this valve and how to shut off the water to the heater.
6. Install a discharge line from the temperature and pressure relief valve in the opening marked “T & P RELIEF VALVE”. Install as specified under “Temperature and Pressure Relief Valve”.
7. After piping has been properly connected to the water heater, open the nearest hot water faucet. Then open the cold water shut off valve and allow the tank to completely fill with water. To purge the lines of any excess air and sediment, keep the hot water faucet open for 3 minutes after a constant flow of water is obtained. Close the faucet and check all connections for leaks.

Please note the following: DO NOT install this water heater with iron piping. The system should be installed only with piping that is suitable for potable (drinkable) water such as copper, CPVC, or polyethylene (PEX). DO NOT use PVC water piping.
DO NOT use any pumps, valves, or fi ttings that are not compatible with potable water.
DO NOT use valves that may cause excessive restriction to water fl ow. Use full-fl ow ball or gate valves only.
DO NOT use tin-lead solder in potable water lines. Use 95/5 tin antimony or other equivalent material.
DO NOT tamper with the energy smart module, electronic thermostat, temperature sensors, heat­ ing elements, electrical connections, or temperature and pressure relief valve. Tampering voids all war­ ranties. Only qualifi ed person should service these components.
DO NOT use with piping that has been treated with chromate’s, boiler seal, or other chemicals.
DO NOT add any chemicals to the system piping which will contaminate the potable water supply.
Closed System/Thermal Expansion
Typically, a closed system includes a pressure reducing valve (PRV) on the cold water inlet (supply line). As water is heated, it expands (thermal expansion). In a closed sys­tem, the volume of water will grow. As the volume of water grows, there will be a corresponding increase in water pressure due to thermal expansion. Thermal expansion can cause premature tank failure (leakage). This type of failure is not covered under the limited warranty. Thermal expansion can also cause intermittent temperature­pressure relief valve operation: water discharged from the valve due to excessive pressure build up. The tempera­ture-pressure relief valve is not intended for the constant relief of thermal expansion. This condition is not covered under the limited warranty.
A properly-sized thermal expansion tank should be in­stalled on all closed systems to control the harmful effects of thermal expansion. Contact a plumbing service agency or your retail supplier regarding the installation of a ther­mal expansion tank.

A thermal expansion tank can help prevent damage to the water heater and other appliances (i.e.: washing machine, ice maker, dishwasher, etc.).
IMPORTANT: Do not plug or remove the temperature and pressure relief valve (T&P valve).
Temperature and Pressure Relief Valve
Explosion Hazard
• Temperature-pressure relief valve must comply with ANSI Z21.22-CSA 4.4 and ASME code.
• Properly sized temperature­pressure relief valve must be installed in opening provided.
• Can result in overheating and excessive tank pressure.
• Can cause serious injury or death.

For protection against excessive pressures and temperatures, a temperature and pressure relief valve must be installed in the opening marked “T&P RELIEF VALVE” (See Figure 5). This valve must be design certi­ ed by a nationally recognized testing laboratory that maintains periodic inspection of the production of listed equipment or materials as meeting the requirements for Relief Valves for Hot Water Supply Systems, ANSI Z21.22. The function of the temperature and pressure relief valve is to discharge water in large quantities in the event of excessive temperature or pressure develop­ing in the water heater. The valve’s relief pressure must not exceed the working pressure of the water heater as stated on the rating plate.
IMPORTANT: Only a new temperature and pressure relief valve should be used with your water heater. Do not use an old or existing valve as it may be damaged or not adequate for the working pressure of the new water heater. Do not place any valve between the relief valve and the tank.

T&P Relief Valve and Pipe Insulation:
6. Spread the slit open and slip the insulation over the cold water (inlet) pipe. Apply gentle pressure along the length of the insulation to ensure it is fully seated around the pipe. Also ensure that the base of insulation is flush with the water heater. Once seated, secure the insulation with duct tape, electrical tape, or equivalent.
7. Repeat steps 5 through 6 for the hot water (outlet) pipe.
8. Add additional sections of pipe insulation as needed.
Solar Installation
If this water heater is used as a solar storage heater or as a backup for the solar system, the water supply temperatures to the water heater tank may be in excess of 120° F (48.8° C). A mixing valve or other temperature limiting valve must be installed in the water supply line to limit the supply temperature to 120° F (48.8° C).
Note: Solar water heating systems can often supply water with temperatures exceeding 180° F (82.2° C) and may result in water heater malfunction.
1. Locate the temperature and pressure relief valve on the water heater (also known as a T&P Relief Valve, (Figure 6).
2. Locate the slit running the length of the insulation.
3 Spread this slit open and slip it up under the T&P
Relief Valve (See Figure 6). Apply gentle pressure to the insulation to ensure it is fully seated on the T&P Relief Valve. Once sealed, secure the insulation with a section of duct tape, electrical tape, or equivalent. IMPORTANT: The insulation or tape must not block the discharge opening or hinder access to the manual relief lever. Ensure a discharge pipe is installed into the T&P valve discharge opening per the instructions manual.
4. Locate the hot water (outlet) & cold water (inlet) pipes to the water heater.
5. Locate the slit running the length of a section of pipe insulation.
