MIXING VALVE USAGE

Water (Potable) heating: All models are considered suitable for water (potable) heating only.

WARNING

Water temperature over 125°F (52°C) can cause severe burns instantly resulting in severe injury or death.
Children, the elderly, and the physically or mentally disabled are at highest risk for scald injury. Feel water before bathing or showering.
Temperature limiting valves are available. Read this instruction manual for safe temperature setting.

HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy space heating, clothes washing, and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/mentally disabled. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a mixing valve, should be used at the hot water taps used by these people or at the water heater. Mixing valves are available from your local plumbing contractor. Consult a Qualified Installer or Service Agency.
Follow mixing valve manufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat, read the “Temperature Regulation” section in this manual.

MATERIALS AND BASIC TOOLS NEEDED

DECIDING ON THE TYPE OF INSTALLATION

There are typically two different types of installation. The installation section of this manual has been broken into these two methods.
Look at your old water heater installation to determine which type of installation you have. After finding out what type of installation you have, look at these options:

Section A
Galvanized Pipe or Copper (Sweat) Piping
The original piping is galvanized pipe or sweat copper and you are going to use a “Water Heater Installation Kit”.

Installation Kit or Individual Parts

**CHECK YOUR TOOLS

**

Section B
Copper (Sweat) Piping
The original piping is copper sweat and you are going to reconnect with sweat joints.

Length of Hard Copper Piping (Size of copper pipe and sweat fittings must be the same size as the original piping.)

**CHECK YOUR TOOLS

**

LOCATING THE NEW WATER HEATER

Facts To Consider About The Location

CAUTION

Property Damage Hazard

• All water heater eventually leak
• Do not install without adequate drainage

Carefully choose an indoor location for the new water heater, because the placement is very important consideration for the safety of the occupants in the building and for the most economical use of the appliance.

Whether replacing an old water heater or putting the water heater in a new location, the following critical points must be observed:

1. Select a location as close as practical or centralized to the point of use. The water heater should be located in an area not subject to freezing temperatures.
2. Selected location must provides adequate clearances for removing the front cover in order to service parts such as the thermostat, element, temperature sensor, anode, and high limit reset. Adequate clearance for servicing this appliance should be considered before installation, such as operating the relief valve, etc.
3. The water heater should be located so it is not subject to physical damage by moving vehicles or area flooding.
4. The selected wall or cabinet must be capable of supporting at least two times the weight of the water heater when filled with water (7 7Ibs).
5. The water heater must be installed in a vertical position with water inlet and outlet connections facing upwards and easily accessible.

Installation of the water heater must be accomplished in such a manner that if the tank or any connections should leak, the flow will not cause damage to the structure. For this reason, it is not advisable to install the water heater in an attic or upper floor.
When such locations cannot be avoided, a suitable drain pan should be installed under the water heater. Drain pans are available from your local plumbing contractor. Such a drain pan must have a minimum length and width of at least 2 inches (51 mm) greater than the water heater dimensions and must be piped to an adequate drain.
Water heater life depends upon water quality, water pressure, water usage, water temperature, and the environment in which the water heater is installed. Water heaters are sometimes installed in locations where leakage may result in property damage, even with the use of a drain pan piped to a drain.
However, unanticipated damage can be reduced or prevented by a leak detector or water shut-off device used in conjunction with a piped drain pan. These devices are available from some plumbing supply wholesalers and retailers, and detect and react to leakage in various ways:

• Sensors mounted in the drain pan that trigger an alarm or turn off the incoming water to the water heater when leakage is detected.
• Sensors mounted in the drain pan that turn off the water supply to the entire home when water is detected in the drain pan.
• Water supply shut-off devices that activate based on the water pressure differential between the cold water and hot water pipes connected to the water heater.

INSULATION BLANKETS
Insulation blankets are available to the general public for external use on electric water heaters but are not necessary with this product. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters.
Should you choose to apply an insulation blanket to this heater, you should follow these instructions below. Failure to follow these instructions can result in fire, serious personal injury, or death.

Do not cover the temperature and pressure relief (T&P) valve with an insulation blanket.
Do not cover the instruction manual. Keep it on the side of the water heater or nearby for future reference.
Do obtain new warning and instruction labels for placement on the blanket directly over the existing labels.

WATER PIPING

DANGER

Water temperature over 125°F (52°C) can cause severe burns instantly resulting in severe injury or death.
Children, the elderly, and the physically or mentally disabled are at highest risk for scald injury.
Feel water before bathing or showering.
Temperature limiting valves are available. Read this instruction manual for safe temperature setting.

HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy space heating, clothes washing, dish washing, cleaning and other sanitizing needs can scald and permanently injury you upon contact. Some people are more likely to be permanently injured by hot water than others.
These include the elderly, children, the infirm, or physically/ mentally disabled. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a mixing valve should be used at the hot water taps used by these people or at the water heater. Valves for reducing point of use temperature by mixing cold and hot water are also available.
Consult a Qualified Installer or Service Agency. Follow manufacturer’s instructions for installation of the valves.
Before changing the factory setting on the thermostat, read the “Temperature Regulation” section in this manual.

WARNING

Toxic Chemical Hazard

• Do not connect non-potable water system

This water heater shall not be connected to any heating systems or components used with a non potable water heating appliance.
Toxic chemicals, such as those used for boiler treatment shall not be introduced into this system.
Water supply system may, because of such events as high line pressure, frequent cut-offs, the effects of water hammer among others, have installed devices such as pressure reducing valves, check valves, back flow preventers, etc. to control these types of problems. When these devices are not equipped with an internal by-pass, and no other measures are taken, the devices cause the water system to be closed. As water is heated, it expands(thermal expansion) and closed systems do not allow for the expansion of heated water.
The water within the water heater tank expands as it is heated and increases the pressure of the water system. If the relieving point of the water heater’s temperature-pressure relief valve is reached, the valve will relieve the excess pressure. The temperature-pressure relief valve is not limited for the constant relief of thermal expansion. This is an unacceptable condition and must be corrected.
It is recommended that any devices installed which could create a closed system have a by-pass and/or the system have an expansion tank or device to relieve the pressure built by thermal expansion in the water system. Expansion tanks are available for ordering through a local plumbing contractor. Contact the local water supplier and/or a service agency for assistance in controlling these situations.
NOTE: To protect against untimely corrosion of hot and cold water fittings, it is strongly recommended that dielectric unions or couplings be installed on this water heater when connected to copper pipe.
Figure 4 shows the typical attachment of the water piping to the water heater. The water heater is equipped with 1/2 inch NPT water connections.

CAUTION

Property Damage Hazard

• Avoid water heater damage.
• Install thermal expansion tank if necessary.
• Do not apply heat to cold water inlet.
• Contact qualified installer or service agency.

NOTE: If using copper tubing, older tubing to an adapter before attaching the adapter to the cold water inlet connection. Do not solder that cold water supply line directly to the cold water inlet, it will harm the dip tube and damage the tank.

WATER PIPING PRESSURE TEST
This section is only for the manufacturer installing the water heater when the installation is to comply with H.U.D. Standards.
When testing the water ways, H.U.D. Standards state: “Water distribution system: All water piping in the water distribution system shall be subjected to a pressure test. The test shall be made by subjecting the system to air or water at 1 00psi for 15 minutes without loss of pressure. When air pressure is used, the water heater shall not be connected during the test.

WARNING

Air Pressure Hazard

• If water piping system is to be air pressure tested, the water heater must be disconnected from the water piping system.
• Failure to disconnect the water heater during air pressure testing of the water system could result in DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE.

TEMPERATURE-PRESSURE RELIEF VALVE

WARNING

Explosion Hazard

• Temperature-pressure relief valve must comply with ANSI Z21.22 and ASME code.
• Properly sized temperature-relief valve must be installed in opening provided.
• Can result in overheating and excessive tank pressure.
• Can cause serious injury or death.

This heater is provided with a properly certified combination temperature- pressure relief valve by the manufacturer.
The valve is certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment of materials as meeting the requirements for Relief Valve for Hot Water Supply Systems, ANSI Z21.22 • CSA4.4, and the code requirements of ASME.
If replaced, the valve must meet the requirements of local codes, but not less than a combination temperature and pressure relief valve certified as indicated in the above paragraph.
The valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater(150psi=1035kPa) and a discharge capacity not less than the water heater input rate as shown in the model rating plate.
For safe operation of the water heater, the relief valve must not be removed from its designated opening nor plugged.
The temperature-pressure relief valve must be installed directly into the fitting of the water heater designed for the relief valve.
Provide tubing so that any discharge will exit only within 6 inches (153mm) above an adequate drain, or external to the building or structure. Be certain that no contact is made with any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances. Excessive length, over 30 feet (9. 14m), or use of more than four elbows can cause restriction and reduce the discharge capacity of the valve.
No valve or other obstruction is to be placed between the relief valve and the tank. Do not connect tubing directly to discharge drain unless a 6 inch air gap is provided. The relief valve must be allowed to discharge water in sufficient quantities, should circumstances demand, to prevent bodily injury, hazard to life, or property damage. If the discharge pipe is not connected to a drain or other suitable means, the water flow may cause property damage.

CAUTION

Water Damage Hazard

• Temperature-pressure relief valve discharge pipe must terminate at adequate drain.

The Discharge Pipe:

• Shall not be smaller in size than the outlet pipe size of the valve, or have any reducing couplings or other restrictions.
• Shall not be plugged or blocked.
• Shall be of material listed for hot water distribution.
• Shall be installed so as to allow complete drainage of both the temperature-pressure relief valve, and the discharge pipe.
• Shall be installed so as to allow complete drainage of both the temperature-pressure relief valve, and the discharge pipe.
• Shall terminate at an adequate drain or external to the building or structure.
• Shall not have any shut-off valve between the relief valve and tank nor in the discharge pipe.

DANGER

Water temperature over 125°F (52°C) can cause severe burns instantly resulting in severe injury or death.
Children, the elderly, and the physically or mentally disabled are at highest risk for scald injury.
Feel water before bathing or showering.
Temperature limiting valves are available. Read this instruction manual for safe temperature setting.

The temperature-pressure relief valve must be manually operated at least once a year. Caution should be taken to ensure that (1) no one is in front of or around the outlet of the temperature pressure relief valve discharge line, and (2) the water manually discharged will not cause any bodily injury or property damage because the water may be extremely hot.
If after manually operating the valve, it fails to completely reset and continues to release water, immediately close the cold water inlet to the water heater, follow the draining instructions, and replace the temperature- pressure relief valve with a new one.

FILLING THE WATEER HEATER

CAUTION

Property Damage Hazard

• Avoid water heater damage.
• Fill tank with water before operating.

Never use this water heater unless it is completely full of water.
To prevent damage to the tank and heating element, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” electrical supply to the water heater.
The manufacturer will not warrant any elements damaged by failure to follow instructions.

To fill the water heater with water:

1. Open the cold water supply valve to the water heater.
   NOTE: The cold water supply valve must be left open when the water heater is in use.

2. To ensure complete filling of the tank, allow air to exit by opening the nearest hot water faucet. Allow water to run until a constant flow is obtained. This will let air out of the water heater and the piping.

3. Check all water piping and connections for leaks. Repair as needed.

4. Never alter or modify the certified construction of the water heater or its components, or bypass any safety features. Doing so voids all warranties.

WIRING DIAGRAM

WATER HEATERS EQUIPPED FOR ONE VOLTAGE ONLY: This water heater is equipped for one type voltage only. Check the rating plate near the bottom access panel for the correct voltage.
DO NOT use this water heater with any voltage other than the one shown on the models rating plate. Failure to use the correct voltage can cause problems which can result in DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. If you have any questions or doubts consult your electric company.
If wiring from your fuse box or circuit breaker box was aluminum for your old water heater, replace it with copper wire. If you wish to reuse the existing aluminum wire, have the connection at the water heater made by a competent electrician. Contact a local electrical contractor and /or the local electric utility.

TEMPERATURE REGULATION

DANGER

Water temperature over 125°F (52°C) can cause severe burns instantly resulting in severe injury or death.
Children, the elderly, and the physically or mentally disabled are at highest risk for scald injury.
Feel water before bathing or showering.
Temperature limiting valves are available. Read this instruction manual for safe temperature setting.

HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy space heating, clothes washing, dish washing, cleaning and other sanitizing needs can scald and permanently injury you upon contact. Some people are more likely to be permanently injured by hot water than others.
These include the elderly, children, the infirm, or physically/ mentally disabled. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a mixing valve should be used at the hot water taps used by these people or at the water heater. Mixing valves are available from your local plumbing contractor. Follow manufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat, see Figure 6.
Never allow small children to use a hot water tap or to draw their own bath water. Never leave a child or handicapped person unattended in a bathtub or shower.
It is recommended that lower water temperatures be used to avoid the risk of scalding. It is further recommended, in all cases, that the water temperature thermostat be set for the lowest temperature which satisfies your hot water needs. This will also provide the most energy efficient operation of the water heater.
KEEPING THE THERMOSTAT SETTING AT 120°F (49°C) OR LOWER WILL REDUCE THE RISK OF SCALDS.
Figure 6 shows the approximate time-to-burn relationship for normal adult skin.

TEMPERATURE ADJUSTMENT

WARNING

• Before removing any access panels or servicing the water heater, make sure the electrical supply to the water heater is turned “OFF”.
• Failure to do this could result in death, serious bodily injury, or property damage.

To change the temperature setting:
The white knob on the front of the water heater is the temperature control. When the “OFF” mark is aligned with the raised indicator arrow, the water heater is off. Turn the knob clockwise to increase the temperature, and counterclockwise to decrease the temperature. The knob is marked with circular indentations of increasing size. The larger the indentation, the higher the temperature setting. See Figure 6. The temperature range of this water heater is 68°F at the lowest setting and 158°F at the maximum setting. This water heater is shipped in the “OFF” position. Adjust the dial to the desired temperature.

TEMPERRATURE SETTINGS
It is recommended that the dial be set lower whenever possible.

FOR YOUR INFORMATION

THERMAL EXPANSION

CAUTION

Property Damage Hazard

• Avoid water heater damage.
• Install thermal expansion tank if necessary.
• Do not apply heat to cold water inlet.
• Contact qualified installer or service agency

Water supply systems may, because of such events as high line pressure, frequent cut-offs, the effects pf water hammer among others, have installed devices such as pressure reducing valves, check valves, back flow preventers, etc. to control these types of problems. When these devices are not equipped with an internal by-pass, and no other measures are taken, the devices cause the water system to be closed. As water is heated, it expands(thermal expansion) and closed systems do not allow for the expansion of heated water.
The water within the water heater tank expands as it is heated and increases the pressure of the water system. If the relieving point of the water heater’s temperature-pressure relief valve is reached, the valve will relieve the excess pressure. The temperature-pressure relief valve is not intended for the constant relief of thermal expansion. This is an unacceptable condition and must be corrected. It is recommended that any devices installed which could create a closed system have a bypass and/or the system have an expansion in the water system. Expansion tanks are available for ordering through a local plumbing contractor.
Contact the local water heater supplier or service agency for assistance in controlling these situations.

STRANGE SOUNDS
Possible noises due to expansion and contraction of some metal parts during periods of heat-up and cool-down do not necessarily represent harmful or dangerous conditions

OPERATION CONDITIONS

WATER ODOR

In each water heater there is installed at least one anode rod(see parts section) for corrosion protection of the tank. Certain water conditions will cause a reaction between this rod and the water.
The most common complaint associated with the anode rod is one of a “rotten egg smell” in the hot water. This odor is derived from hydrogen sulfide gas dissolved in the water. The smell is the result of four factors which must all be present for the odor to develop:

• A. A concentration of sulfate in the supply water.
• B. Little or no dissolved oxygen in the water.
• C. A sulfate reducing bacteria which has accumulated within the water heater(this harmless bacteria is nontoxic to humans).
• D. An excess of active hydrogen in the tank. This is caused by the corrosion protective action of the anode.

Smelly water may be eliminated or reduced in some water heater models by replacing the anode(s) with one of less active material, and then chlorinating the water heater tank and all hot water lines. Contact the local water heater supplier oe service agency for further information concerning an Anode Replacement and chlorination treatment; we can only suggest that chlorination or aeration of the water supply be considered to eliminate the water problem.

Do not remove the anode leaving the tank unprotected. By doing so, all warranty on the water heater tank is voided.

“AIR” IN HOT WATER FAUCETS

WARNING

Explosion Hazard

• Flammable hydrogen gases may be present.
• Keep all ignition sources away from faucet when turning on hot water.

HYDROGEN GAS:
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 and explosive.
To prevent the possibility of injury under these conditions, we recommend the hot water faucet, located farthest away be opened for several minutes before any electrical appliances which are connected to the hot water system are used(such as a dishwasher or washing machine). If hydrogen gas is present, there will probably be an unusual sound similar to air escaping through the pipe as the hot water faucet at the time it is open.

HIGHER WATER TEMPERATURE SHUT OFF SYSTEM
A non-adjustable high temperature limit control operates before steam temperatures are reached. The high limit switch must be reset manually when it operates. BECAUSE THE HIGH LIMIT OPERATES ONLY WHEN ABNORMALLY HI GH WATER TEMPERATURES ARE PRESENT, IT IS IMPORTANT THAT A QUALIFIED SERVICE AGENT BE CONTACTED TO DETERMINE THE REASON FOR OPERATION BEFORE RESETTING.

** WARNING

**

• Before removing any access panels or servicing the water heater, make sure the electrical supply to the water heater is turned “OFF”.
• Failure to do this could result in death, serious bodily injury, or property damage.
• Turn off and unplug the water heater. Do not attempt to reset thermostat with power on.
• Remove the front panel, see “Removing Front Panel” in the Periodic Maintenance section.
• Removing the insulation to expose the reset button.
• Reset the high limit by pushing in the red button.
• Replace the insulation so that ii completely covers the thermostat and element.
• Replace the front panel.
• Plug in and turn on the water heater.

PERIODIC MAINTENANCE

ANODE ROD INSPECTION

CAUTION

Property Damage Hazard

• Avoid water heater damage.
• Inspection and replacement of anode rod required.

The anode rod is used to protect the tank from corrosion. Most hot water tanks are equipped with an anode rod. The submerged rod sacrifices itself to protect the tank. Instead of corroding the tank, water ions attack nd eat away the anode rod. This does not affect the water’s taste or color. The rod must be maintained to keep the tank in operating condition.

NOTE: Artificially softened water is more corrosive because the process substitutes sodium ions for magnesium and calcium ions.
The use of a water softener may decrease the life of the water heater tank.

Anode deterioration depends on water conductivity, not necessarily water condition. A corroded or pitted anode rod indicates high water conductivity and should be checked and/ or replaced more often than an anode rod can extend the life of your water heater. Inspection should be conducted by a qualified technician, and at a minimum should be checked every three years. The anode rod in this unit is attached to the element flange. For removal instructions, see “ELEMENT CLEANING/ REPLACEMENT.”
Typical (but not all) signs of a depleted anode rod are as follows:

1. The majority of the rods diameter is less than 3/8″
2. Significant sections of the support wire(approximately 1/3 or more if the anode rod’s length) are visible.

If the anode rod shows signs of either or both it should be replaced.
NOTE: Whether re-installing or replacing the anode rod, check for any leaks and immediately correct if found.

TEMPERATURE PRESSURE RELIEF VALVE OPERATION

DANGER

• Burn hazard
• Hot water discharge.
• Keep clear of relief valve discharge outlet.

The temperature-pressure relief valve must be manually operated at least once a year.
When checking the temperature-pressure relief valve operation, make sure that (1) no one is in front of or around the outlet of the temperature-pressure relief valve discharge line, and(2) that the water discharge will not cause any property damage, as the water may be extremely hot, see figure 7.

**TEMPERATURE-PRESSURE RELIEF VALVE

**

If after manually operating the valve, it fails to completely reset and continues to release water, immediately close the cold water inlet to the water heater, follow the draining instructions, and replace the temperature- pressure relief valve with a new one.
If the temperature-pressure relief valve on the appliance weeps or discharges periodically, this may be due to thermal expansion.
You may have a check valve installed in the water line or a water meter with a check valve. Consult your local water supplier or service agency for further information. Do not plug or remove the temperature-pressure relief valve.

DRAINING

**DANGER

**

• Burn hazard
• Hot water discharge.
• Keep clear of relief valve discharge outlet.

The water heater should be drained if being shut down during freezing temperatures. Also periodic draining and cleaning of sediment from the tank may be necessary.

1. Turn off and unplug the water heater from the electric outlet.
2. CLOSE the cold water inlet valve to the water heater.
3. OPEN a nearby hot water faucet and leave open to allow for draining.

If you are not thoroughly familiar with your water heater and safety practices, contact a qualified installer to check the water heater.

LEAKAGE CHECKPOINTS

WARNING

• Before removing any access panels or servicing the water heater, make sure the electrical supply to the water heater is turned “OFF”.
• Failure to do this could result in death, serious bodily injury, or property damage.

WARNING

Read and understand this instruction manual and safety messages before installing, operating, or servicing this water heater.
Failure to follow these instructions and safety messages could result in death or serious injury.
This manual must remain with water heater.

Read this manual first. Make sure the electrical power supply has been turned “OFF” before checking the tank for leakage.

• A. Condensation and dripping may be seen on pipes if the water temperature is low in humid weather or pipe connections may be leaking.
• B. Small amounts of water from temperature-pressure relief valve may be due to thermal expansion or high water pressure in your area. If the valve is not piped to an open drain the released water could be mistaken for a leaking heater, see “Thermal Expansion” section.
• *C. The temperature-pressure relief valve may be leaking at the tank fitting.
• D. Water on the side of the tank may be condensation due to the panel or insulation not being in place.
• E. Water in the water heater bottom or on the floor may be from  condensation, loose connections, or the relief valve. DO NOT replace the water heater until a full inspection of all possible water sources is made and necessary corrective steps taken.
  Leakage from other appliances, water lines, or ground seepage should also be checked.
  To check where threaded portion enters tank, insert cotton swab between jacket opening and fitting. If cotton is wet, follow “Draining” instructions in the “Periodic Maintenance” section and then remove fitting. Put pipe dope or Teflon tape on the threads and replace. Then follow “Filling the Water Heater” instructions in the “Installing the New Water Heater” section.
