Components included with the water heater:

• Drain Valve
• Temperature and Pressure Relief Valve
• Use and Care Manual and Warranty
  NOTE: Some components may ship factory installed.
  B. Locating the Water Heater

CAUTION
All water heaters eventually leak. Locate the water heater where any leakage from the relief valve, related piping, tank, or connections will not result in damage to surrounding areas or lower floors of the building. Any water heater should be installed in such a manner that if it should leak the resulting flow of water will not cause damage to the area in which it is installed. National Plumbing codes require a drain pan for any water heater installation. This drain pan should be sized with a maximum depth of 2”, and a minimum diameter 2” greater than the diameter of the water heater. The drain pan should empty into an open drain line. This drain line should be 3/4” ID minimum, piped to an open drain. Leakage damages ARE NOT covered by warranty. Failure to install a drain pan is the sole responsibility of the owner and/or installer. Reference UPC 2000 (Uniform Plumbing Code) Section 510 – Protection from Damage or IPC 200 (International Plumbing code) Section 504 – Safety Devices. Leakage damages ARE NOT covered by warranty. In addition, water leak detection devices and automatic water shutoff valves are readily available at plumbing supply houses. IT IS HIGHLY RECOMMENDED BY THE MANUFACTURER TO INSTALL WATER LEAK DETECTION DEVICES AND AUTOMATIC SHUTOFF VALVES IN ANY WATER HEATER INSTALLATION WHERE A LEAKAGE OF WATER COULD RESULT IN PROPERTY DAMAGES.
WARNING
This water heater is certified for indoor use only. DO NOT INSTALL OUTDOORS. Outdoor installations ARE NOT covered by warranty. Failure to install the water heater indoors could result in property damage, severe personal injury, or death.
This water heater must be installed upright in the vertical position as described in this manual. DO NOT attempt to install this water heater in any other orientation. Doing so will result in improper water heater operation and property damage, and could result in serious personal injury or death.

1. Installation Area (Mechanical Room) Operating Conditions
   • Ensure ambient temperatures are higher than 32 o o F / 0 C and lower than 104 o o F / 40 C
   • Avoid continuously high levels of humidity
   • Never close existing ventilation openings
   NOTE: When installing in a zero clearance location, it may not be possible to read or view some product labeling. It is recommended to make note of the water heater model and serial number.
   CAUTION
   The service life of the water heater’s exposed metallic surfaces, such as the junction box, is directly influenced by proximity to damp and salty marine environments. In such areas higher concentration levels of chlorides from sea spray coupled with relative humidity can lead to degradation of water heater components.
   WARNING
   Incorrect operating conditions can lead to damage to the heating system and put safe operation at risk. Ensure that the installation location adheres to the information included in this manual. Failure to do so could result in property damage, serious personal injury, or death. Failure of the water heater or components due to incorrect operating conditions IS NOT covered by product warranty.

2. Choose a location for the water heater as centralized to the piping and electrical system as possible. Also, locate the water heater and domestic water piping where it will not be exposed to freezing temperatures. All piping should be insulated. Additionally, place the water heater so that the drain, controls, and inlets/outlets are easily accessible.
   NOTE: To save on heating costs and improve energy efficiency keep the distance between the water heater and fixtures to a minimum to reduce heat loss from excess piping and keep friction loss at a minimum. Ensure all water heater piping is properly insulated to minimize heat loss.
   NOTE: If you do not provide the minimum clearances shown in Figure 1, it might not be possible to service the water heater without removing it from the space.
   NOTE: A combustible door or removable panel is acceptable front clearance.
   NOTE: In the State of California, the water heater must be braced, anchored, or strapped to avoid moving during an earthquake. Contact local utilities for code requirements in your area. Visit http://www.dsa.dgs.ca.gov or call 1-916-445-8100 and request instructions.
   However, applicable local codes shall govern installation. For residential water heaters of a capacity of greater than 52 gallons, consult the local building jurisdiction for acceptable bracing procedures.

3. Check area around water heater. Remove any combustible materials, gasoline, and other flammable liquids. Figure 1 – Recommended Service Clearances – NOTE: Overhead View Not Representative of All Models
   DENGER This water heater must not be located near flammable liquids such as gasoline, butane, liquefied propane, adhesives, solvents, paint thinners, etc., as the controls of this water heater could ignite these vapors and cause an explosion resulting in property damage, severe personal injury, or death.

4. If the water heater is to replace an existing water heater, check for and correct any existing system problems such as:
   • System leaks
   • Location that could cause the system and water heater to freeze and leak
   • Incorrectly-sized expansion tank

5. This water heater must be installed vertical on a level surface.
   C. Water Chemistry Requirements
   CAUTION
   Chemical imbalance of the water supply may affect efficiency and cause severe damage to the appliance and associated equipment. Water quality must be professionally analyzed to determine whether it is necessary to treat the water. Various solutions are available to adjust water quality. Adverse water quality will affect the reliability of the system. In addition, operating temperatures above 135 o F will accelerate the build-up of lime scale and possibly shorten appliance service life. Failure of an appliance due to lime scale build-up, low pH, or other chemical imbalance IS NOT covered by the warranty. The water must be potable, free of corrosive chemicals, sand, dirt, and other contaminates. It is up to the installer to ensure the water does not contain corrosive chemicals or elements that can damage the heat exchanger. Potable water is defined as drinkable water supplied from utility or well water in compliance with EPA secondary maximum contaminant levels (40 CFR Part 143.3). If the water contains contaminants higher than outlined by the EPA, water treatment is recommended and additional, more frequent maintenance may be required. If you suspect that your water is contaminated in any way, discontinue use of the appliance and contact an authorized technician or licensed professional.

• Water pH between 6.5 and 8.5
  • pH levels below 6.5 can cause an increase in the rate of corrosion. pH of 8.5 or higher can potentially cause lime scale build-up
  • Maintain water pH between 6.5 and 8.5. Check with litmus paper or have it chemically analyzed by a local water treatment company.
  • If the pH is not between 6.5 and 8.5, consult a local water treatment company for solutions.

• Hardness less than 7 grains (120 mg/L)
  • Hardness levels above the required amounts can lead to lime scale build-up throughout the system. Water below 5 grains/ gallon (85 mg/L) may be over softened.
  • Consult local water treatment companies for unusually hard water areas (above the required amounts) or for other treatment solutions if water is being over softened (below 5 grains/gallon [85 mg/L]).

• Chloride concentration less than 100 ppm (mg/L)
  • Do not fill appliance or operate with water containing chlorides in excess of 100 ppm (mg/L).
  • Using chlorinated fresh water should be acceptable as levels are typically less than 5 ppm (mg/L).
  • Do not connect the appliance to directly heat swimming pool or spa water.

• Total Dissolved Solids (TDS) less than 500 ppm (mg/L)
  • Total dissolved solids are minerals, salts, metals, and charged particles that are dissolved in water.
  • The greater the amounts of TDS present, the higher the corrosion potential due to increased conductivity in the water.
  • If using softened water to fill the appliance, it is still possible to have high TDS. This water can be corrosive. Consult local water treatment companies for other treatment solutions to reduce this affect.
  *NOTE: To promote appliance service life, it is strongly recommended to follow the maintenance procedures in this manual.

CAUTION
Failure of electric elements due to lime scale build-up on the heating surface, low pH, or other imbalance IS NOT covered by the warranty.

Piping

A. Plumbing
It is mandatory that all plumbing be done in accordance with federal, local, and state plumbing codes and practices. Failure to properly install the water heater WILL VOID the warranty. It is also necessary to use both thread tape and pipe sealing compound on all mechanical plumbing connections. It is recommended to use unions on the hot and cold water connections to easily disconnect the water heater for servicing.
CAUTION
Dielectric fittings must be used on water connections.
Do not disturb the factory seal on the water heater connections! Use two wrenches when tightening or loosening the piping, valve, or adapters at the water heater. One to secure the water heater fitting, the other to tighten or loosen connections to the water heater. DO NOT over-tighten!
Do not apply heat to the Hot or Cold water heater connections. If sweat connections are used, sweat tubing to the adapter before fitting adapter to the water connections on the heater. Any heat applied to the water heater connections will permanently damage the dip tube and/or heat traps. Damages due to improper installation practices ARE NOT covered by warranty. Water piping, fittings, and valves must be properly installed for the correct and safe operation of this water heater. Please note the following:

• DO NOT install this water heater with iron or PVC piping. The system should be installed only with piping that is suitable for potable (drinkable) water.

• DO NOT use any pumps, valves, or fittings that are not compatible with potable water.

• DO NOT use valves that may cause excessive restrictions to water flow. Use full flow ball or gate valves only.

• DO NOT use 50/50 tin-lead solder (or any lead based solder) in potable water lines. ONLY use 95/5 Tin / antimony or other equivalent materials.

• DO NOT tamper with thermostat heater elements, electrical connections, or temperature and pressure relief valves. Tampering with any of these components is DANGEROUS and can result in property damage, severe injury, or death. Tampering voids all warranties. Only qualified technicians should service the above components.

• DO NOT use with piping that has been treated with chromates, boiler seal, or other chemicals.

• DO NOT add any chemicals to the system piping which will contaminate the potable water supply.

• DO NOT install check valves on the cold water supply line to the water heater. The water connections must be installed in accordance with all local and national plumbing codes, or any applicable standard which prevails.

• Pipe material must be suitable to meet local codes and industry standards.

• The pipe must be cleaned and without blemish before any connections are made.

• Isolation (shut-off valves) should be used to ease future servicing.

• All piping should be insulated.
  1. Install a shut-off or check valve or both on the cold inlet connection on the top or side of the heater.
  2 Connect the cold water supply line to the shut-off valve or check valve. Refer to piping Applications, this manual.

• Connect the hot water line to the top or side hot outlet connection on the top of the water heater. Then connect the hot water line.
  3. Ensure the T&P Valve is installed in the ports provided on the side or top of the water heater.

B. Recirculation Lines
In some installations a return circulation line may be installed. The recirculation line can be connected to the hot water inlet connection using a tee.
C. Thermal Expansion
A check valve may be installed in the cold water inlet line as a separate backflow preventer, or may be part of a pressure reducing valve, water meter, or water softener. An “open water system” refers to a system without a check valve. A “closed water system” refers to a system with a check valve installed in the cold water inlet line. As water is heated, it expands in volume and increases pressure within the water system. This action is referred to as “thermal expansion”. In an open water system, expanding water which exceeds the capacity of the system flows back into the city main where pressure is easily dissipated.
A closed water system prevents expanding water from flowing back to the city main. The resulting thermal expansion can rapidly increase pressure in the water heater and system piping. This rapid pressure increase can exceed the setting of the pressure relief valve, causing it to operate during each heating cycle, resulting in discharge from the T&P. This rapid and repeated expansion and contraction of components in the system can cause premature failure of system components, including the relief valve and possibly the water heater. Replacing the relief valve will not correct thermal expansion. A potable hot water expansion tank is required to offset thermal expansion. Expansion tanks are designed with an air cushion built in that compresses as system pressure increases, thereby relieving the overpressure condition and eliminating repeated operation of the relief valve. This expansion tank should be installed in the cold water line between the water heater and check valve, and must be sized for the entire water volume of the hot water system. See piping Applications. Other methods of controlling thermal expansion are available. Check with the local water utility to determine if a check valve exists in the cold water inlet line. Contact your installing contractor, water supplier, or plumbing inspector for additional information regarding thermal expansion.
D. Condensation
Condensation can form on the water heater when it is first filled with water, and may also occur with a heavy water draw and very cold inlet water temperature. This condition is not unusual and will disappear as the water becomes heated. However, if the condensation should continue, examine the piping and fittings for possible leaks.
E. Insulation Blankets
WARNING
If local codes require external application of insulation blanket kits, the manufacturer’s instructions included with the kit must be carefully followed.
In addition, pay careful attention to the following so as not to restrict the proper function and operation of the water heater:

• Do not cover the operating or warning labels attached to the water heater or attempt to locate them on the exterior of the insulation blanket.
• Do not apply insulation to the top of the water heater. This could interfere with the safe operation of the electrical junction box.
• Do not cover the jacket access panel to the thermostat and heating element or T&P valve.
• Inspect the insulation blanket frequently. Failure to follow these instructions could result in property damage, severe personal injury, or death.

F. Temperature and Pressure Relief Valve
For protection against excessive pressures and temperatures in this water heater, install temperature and pressure protective equipment as required by local codes, but not less than a combination T&P valve meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22B / CSA 4.4-M99 by a nationally recognized testing laboratory that maintains periodic inspection of production listed equipment and materials. This valve must be marked with a maximum set pressure not to exceed the marked maximum working pressure of the water heater. Install the T&P valve into the top or side opening provided and marked for this purpose on the water heater. The T&P valve must be plumbed down so discharge can exit at least 6” above the structural floor. The relief line cannot be in contact with any live electrical parts.

To avoid water damage or scalding due to relief valve operation:

• Discharge line must be connected to relief valve outlet and run to a safe place of disposal. Terminate the discharge line in a manner that will prevent possibility of severe burns or property damage should the relief valve discharge.
• Discharge line must be as short as possible and the same size as the valve discharge connection throughout its entire length.
• Discharge line must pitch downward from the valve and terminate at least 6” above the floor drain, making discharge clearly visible.
• The discharge line shall terminate plain, not threaded, with a material serviceable for temperatures of 375 F or greater.
• Do not pipe discharge to any location where freezing could occur.
• No valve may be installed between the relief valve and heater or in the discharge line. Do not plug or place any obstruction in the discharge line.
• Test the operation of the relief valve after filling and pressurizing the system by lifting the lever. Make sure the valve discharges freely. If the valve fails to operate correctly, immediately replace with a new properly rated relief valve.
• Test T&P valve at least once annually to ensure the waterway is clear. If valve does not operate, turn the heater “off” and call a plumber immediately.
• Take care whenever operating relief valve to avoid scalding injury or property damage.

FAILURE TO COMPLY WITH THE ABOVE GUIDELINES COULD RESULT IN FAILURE OF RELIEF VALVE OPERATION, RESULTING IN POSSIBILITY OF SUBSTANTIAL PROPERTY DAMAGE, SEVERE PERSONAL INJURY, OR DEATH. The pressure relief rating of the relief valve MUST NOT EXCEED 150 PSI, and not exceed the maximum working pressure of the water heater as marked on the rating plate. Failure to follow these instructions could result in property damage, severe personal injury, or death due to scalds.
WARNING
Do not thread a cap or plug into the relief valve or block relief valve outlet line under any circumstances! Explosion and property damage, serious injury, or death may result.
RE-INSPECTION OF T&P RELIEF VALVES: T&P valves should be inspected AT LEAST ONCE EVERY THREE YEARS, and replaced if necessary, by a licensed plumbing contractor or qualified service technician to ensure that the product has not been affected
by corrosive water conditions and to ensure that the valve and discharge line have not been altered or tampered with illegally.
Certain naturally occuring conditions may corrode the valve and its components over time, rendering the valve inoperative. Such conditions can only be detected if the valve and its components are physically removed and inspected. Do not attempt to conduct an inspection on your own. Contact your plumbing contractor for a re-inspection to assure continued safety.
FAILURE TO RE-INSPECT THE T&P VALVE AS DIRECTED COULD RESULT IN UNSAFE TEMPERATURE AND/OR PRESSURE BUILDUP WHICH CAN RESULT IN PROPERTY DAMAGE, SERIOUS PERSONAL INJURY, OR DEATH.
G. Scalding
WARNING
An ASSE 1017 or ASSE 1070 temperature limiting or mixing valve is recommended in installations servicing disabled or elderly persons, or children. Mixing valves can reduce but do not eliminate the risk of scalding.
To avoid scalding:

• Set the water heater set point temperature as low as possible.
• Feel water before bathing or showering.
• If thermostatic valves are required, use devices specifically designed for such purpose. Install these devices in accordance with instructions provided by the manufacturer. Failure to install a temperature limiting or mixing valve and follow these instructions could result in property damage, severe personal injury, or death due to scalds.

This water heater can deliver scalding water. Be careful whenever using hot water to avoid scalding injury. Certain appliances such as dishwashers and automatic clothes washers may require increased water temperatures. By setting the thermostat on this heater to obtain the increased water temperature required by these appliances you may create the potential for scald injury. To protect against injury, install a mixing valve in the water system. This valve will reduce point of use discharge temperatures by mixing cold and hot water in branch supply lines. Such valves are available from your local plumbing supplier.

Water temperature over 125°F can cause severe burns instantly or death from scalds. Children, disabled and elderly are at highest risk of being scalded. See instruction manual before setting temperature at water heater. Feel water before bathing or showering. Temperature limiting valves are available, see manual.
Table 1 details the relationship of water temperature and time with regard to scald injury and may be used as a guide in determining the safest water temperature for your applications.
H. Filling the Heater

• Make certain that the drain valve is completely closed.
• Open the shut-off valve in the cold water supply line.
• Open the hot water faucets to allow air to vent from the heater and piping.
• Allow sufficient time for the heater to completely fill with water.
• Verify the element is installed correctly. Check for leaks.

CAUTION
When filling the water heater, open a hot water tap to release air in the tank and piping. The tank must be full of water before the heais turned on. Failure to ensure the water heater is full before turning it on could result in damage to the water heater and other properdamages. Such damages ARE NOT covered by water heater warranty.

Failure to refill the tank before restoring power to the water heater will result in damage to the heating element and property damage. Such damages ARE NOT covered by warranty.
D. Anode Rod
This water heater is equipped with a magnesium anode rod. Anode rods are sacrificial components that counteract water chemistry to minimize or eliminate tank corrosion.
The anode rod should be inspected annually and replaced as necessary to prolong tank life. Have the supply water quality professionally analyzed, as local water conditions will influence the duration for inspection and replacement of the anode rod.
The use of a water softener may increase the speed of anode consumption. More frequent inspection of the anode is needed when using softened or treated water.
Water with high sulfate and/or mineral content can produce a rotten egg odor in heated water. Chlorinating the water supply may minimize this problem.
NOTE: Do not remove the anode rod from an operating water heater. Operating the water heater without the anode rod will shorten the life of the tank and VOID the warranty.

Maintenance

Considerations

• To avoid electric shock, disconnect electrical supply before performing maintenance.
• To avoid severe burns, allow heater to cool before performing maintenance.

NOTE: In addition to the routine maintenance detailed in this manual, this water heater should be inspected annually by a qualified service technician to assure that all the equipment is operating safely and efficiently. The owner should make necessary arrangements with a qualified heating contractor for periodic maintenance of the heater. Installer must also inform the owner that lack of proper care and maintenance may result in a hazardous condition, premature heater failure, and void the warranty.
Routine preventative maintenance ensure the water heater operates safely and efficiently over its service life. The Owner / User may perform the maintenance activities described below.
Monthly (Every two weeks in hard water locations)
It is recommended that a few quarts of water be drained from the heater. This will flush sediment deposits from the bottom of the heater and lengthen the heater’s service life. Turn off power to the heater during flushing operation, so the elements will not be damaged.
CAUTION
Failure to shut off the heater when draining may damage the heating element. Operating a partially filled / empty water heater could lead to damage from “dry-firing”. Failures due to such damage ARE NOT covered by warranty.
WARNING
Water drained from the water heater may be scalding hot. Take care to avoid scalding. Wear gloves and safety glasses, and direct water to a safe drainage location. It is recommended to turn power off to the water heater and run water at a hot water faucet until it cools BEFORE draining water from the heater. Failure to comply with this warning could result in property damage, severe personal injury, or death.
To flush the tank, attach a hose to the field installed drain valve. Close the cold water supply line shut-off valve. Open the drain valve and hot water faucet(s) to vent heater while draining. Direct the flow of water to a drain or bucket where it will not cause damage. Flush until water runs clear to complete this operation. Close drain valve and reopen the supply line shut-off valve. Close the hot water faucet(s) once all air has been bled from the system (when water runs freely). Make certain that the heater is completely full of water before restoring power.
Periodically (At least twice a year)
Check around the water heater and related plumbing for leaks. If the combination temperature and pressure relief valve discharges periodically, or water is leaking from around the heating elements, there may be a problem with your water system. DO NOT ATTEMPT TO REPAIR LEAKS YOURSELF! Contact a qualified service contractor for assistance.
Check the area around the water heater for flammable liquids or combustible materials. If any are found, remove from the area.
Vacation (Extended shut-off periods)
During extended mild or warm weather periods when hot water will not be in use, shut off the electric power to the tank. When hot water is needed again, restore power to the water heater.
During extended cold weather periods when hot water will not be in use and prone to freezing conditions, shut off electric power to the tank, close the supply line shut-off valve, open the drain valve and drain the water heater to a safe drainage location (as detailed previously). Once drained, close the drain valve. When hot water is needed again, restore the water supply to the tank. Once the tank is full, restore power.
WARNING
Water drained from the water heater may be scalding hot. Take care to avoid scalding. Wear gloves and safety glasses, and direct water to a safe drainage location. It is recommended to turn power off to the water heater and run water at a hot water faucet until it cools BEFORE draining water from the heater. Failure to comply with this warning could result in property damage, severe personal injury, or death. Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two weeks or more).
HYDROGEN GAS IS EXTREMELY FLAMMABLE! To dissipate such gas and reduce the risk of injury, it is recommended that the kitchen sink hot water faucet be opened for several minutes before using any electrical water heater connected to the hot water system. If hydrogen is present, there will be an unusual sound, such as air escaping through the pipe as water begins to flow. Do not smoke or use an open flame near the faucet while it is open. Failure to follow this warning could result in property damage, severe personal injury, or death.
The maintenance activities described below are only to be performed by the Installer / Qualified Service Provider. These maintenance items should be performed during recommended annual service and any service calls.

1. Ask the owner / user if there have been any issues with the water heater. Diagnose any heater issues and repair / replace parts as necessary.
2. Check the water heater and related plumbing for leaks. Repair any that are found.
3. Check the area around the water heater for flammable liquids or combustible materials. If any are found, remove from the area.
4. Check the heating element while the heater is in operation. If the element is hissing / singing excessively, it may need to be cleaned. Inspect the element and clean if necessary.
5. Inspect the Temperature and Pressure (T&P) Relief Valve. See instructions below.
6. Turn power supply off to the water heater. Open the drain valve and drain a few gallons of water from the tank to clear any hard water deposits. Once complete, close the drain valve and restore power to the water heater.

WARNING
T&P Relief Valve Maintenance Instructions:

• Annually: Certain naturally occuring mineral deposits may adhere to the valve, blocking waterways and rendering the valve inoperative. The T&P Relief Valve lever must be operated to ensure the waterways are clear. If waterways are clear, hot water will discharge from the valve. Take precautions to avoid personal injury and property damage from contact with hot water. Before operating lever, check to see that a discharge line is connected to the valve, directing the flow of hot water from the valve to a proper place of disposal.
• Replacement of the valve is required if no water flows when the lever is operated. Turn the water heater off until the valve is replaced. If water flows from the valve, drain a few gallons from the tank to ensure the water flows freely.
• At least once every three years: To ensure that the T&P valve has not been affected by corrosive water conditions and that the valve and discharge line have not been altered or tampered with illegally, relief valves should be inspected, and replaced, if necessary, by a licensed plumbing contractor or qualified service technician. Failure to comply with these guidelines could result in failure of relief valve operation, and possibly result in substantial property damage, severe personal injury, or death.

Leakage Checkpoints
A. Condensation may be seen on pipes in humid weather or pipe connections may be leaking.
B. The primary anode rod may be leaking.
C. Small amounts of water from the temperature / pressure relief valve may be due to thermal expansion or high water pressure in your area.
D. The temperature / pressure relief valve may be leaking at the tank fitting.

PROCEDURES FOR WARRANTY SERVICE REQUESTS
Any claim for warranty assistance must be made promptly. Determine if the water heater is “in-warranty” (that is, within the applicable warranty period) by reviewing a copy of the original sales receipt. The Owner must present a copy of the original sales receipt for a warranty service request. If the water heater is “in-warranty”, contact the retailer from whom the water heater was purchased (or the installer) for assistance. Be prepared to provide the retailer or installer with a copy of the original receipt, complete model and serial numbers, and the date of installation of the water heater, in addition to explanation of the water heater problem. Warranty coverage is subject to validation of “in-warranty” coverage by the manufacturer claims department personnel. All alleged defective or malfunctioning components must be returned to the manufacturer via the local distribution channels where original purchase was made.
NOTE: Any components or heaters returned to the manufacturer for warranty analysis will become the property of the manufacturer and will not be returned, even if credit is denied. If all warranty conditions are satisfied, the manufacturer will provide replacement components to the retailer.
