  3. Water Chemistry Requirements

    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 reliability of the system. In addition, operating temperatures above 135oF 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.
Part 3 – Piping
  1. 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 dope on all mechanical plumbing connections. Install unions on the hot and cold water connections to easily disconnect the water heater for servicing.
    1. Install a shut-off valve on the inlet connection on the top of the heater. Connect the cold water supply line to the shut-off valve. Refer to piping Applications, this manual.
    2. Connect the hot water line to the connection marked “HOT” on the top of the water heater.
    3. Install the T&P Valve in the opening provided near the top of the heater.
    4. Install the drain valve in the opening provided near the bottom of the heater.
  2. Thermal Expansion
  3. 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.
  4. Insulation Blankets
    Insulation blankets for external use on electric water heaters are not necessary with this water heater. An insulation blanket is meant to reduce the standby heat loss encountered with storage tank heaters. This water heater meets or exceeds National Appliance Energy Conservation Act standards with respect to insulation and energy factor requirements, thus making an insulation blanket unnecessary. The manufacturer’s warranty does not cover any damages or defects caused by the installation, attachment, or use of any type of energy saving or other unapproved devices (other than those authorized by the manufacturer) into, onto, or in conjunction with the water heater. The use of unauthorized energy saving devices may shorten the life of the water heater and endanger life and property. The manufacturer disclaims any responsibility for any losses or injuries resulting from the use of such unauthorized devices.
  5. 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 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.
  6. Scalding
    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. Table 5 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.
  7. Filling the Heater
  8. Applications

PIPING NOTES:
The following notes are applicable to all of the piping applications demonstrated on this page.

  1. Minimum pipe size should match connection size. Upsize pipe accordingly if greater flow is required.
  2. A thermal expansion tank suitable for potable water must be sized and installed within this piping system between the backflow preventer and the cold water inlet.
  3. All circulators should have an integral flow check.
  4. Drains and check valve between unit and storage tank will assist in purging air from system.
  5. These drawings are meant to demonstrate system piping only. The installer is responsible for all equipment and detailing required by local codes. In Massachusetts, you must install a vacuum relief valve per 248 CMR.
  6. Mixing valve application is optional, but recommended to help prevent scalding. See Part 3 for more information.

Part 5 – Installation Checklist
Part 6 – Operation

After water and electrical connections have been made and tank is filled with water, turn on power to the heater. The heater is now in operation.

  1. Combination Thermostat and High Limit Control (ECO) After water and electrical connections have been made and tank is filled with water, turn on power to the heater. The heater is now in operation. Each water heater thermostat is a combination Thermostat – High Limit Control (ECO). Thermostats are located above the heating elements. If for any reason the water temperature becomes excessively high, the ECO breaks the circuit to the heating element. Once the switch opens it must be reset manually. However, THE CAUSE OF THE OVER TEMPERATURE CONDITION MUST BE CORRECTED FIRST.
  2. Thermostat Adjustment and ECO Reset There are three thermostats on these water heaters. If temperature adjustment is necessary, TURN OFF POWER TO HEATER, remove black access cover and insulation. The thermostat protective cover SHOULD NOT be removed. Set temperature indicator to desired temperature. Replace insulation and the black access cover. Turn on power to the heater.

IF YOU NEED TO ADJUST THERMOSTAT(S) OR RESET THE ECO (RED RESET BUTTON)

STEP #1 – Turn off power to the water heater by removing fuse or shutting off at circuit breaker.
STEP #2 – Remove the two screws that hold the access cover in place. Remove the cover.
STEP #3 – Remove the insulation to expose the thermostat.
STEP #4 – See Figure 11

  1. Reset the ECO by pushing in the red button marked “RESET”.
  2. Adjust the water temperature by turning the white adjustment knob. Turning the knob to the right (clockwise) makes the water hotter. Turning the knob to the left (counterclockwise) makes the water cooler.

Step #5 – Replace the insulation.
Step #6 – Reattach the access cover with the two screws.
Step #7 – Restore power by replacing the fuse or turning on the circuit breaker.
Step #8 –

  1. After resetting the ECO, ensure the water heater is operating properly before leaving the installation.
  2. After adjusting the water temperature, allow the water heater enough time to heat the water to temperature. After the water heater has stopped heating, measure the water temperature at a hot water outlet in the structure.

Step #9 – If the water heater is operating properly and the water temperature is satisfactory, adjustment is complete.

C. Heating Element Replacement Procedure

Step #1 – Turn off power to the water heater. Use a Phillips Head screwdriver to remove the wires from the element.
Step #2 – Run hot water at a faucet in the system. When it runs cold, shut off the faucet. Then shut off water at the main cold water inlet or, if possible, valve off the water heater from the system. Drain the water from the system, or just the water heater if it can be isolated from the system.
Step #3 – Remove the element with a 1 1/2” socket wrench or element tool.
Step #4 – Inspect the removed element. Determine whether the replacement element will need a square or circular gasket and washer.

Step #5 – Ensure thread and opening are completely free of debris. Use a nylon brush to clear away any debris.
Step #6 – Put a small amount of NSF approved lubricant and sealant on the appropriate gasket and/or washer for the installation. Put the gasket and/or washer on the element.
Step #7 – Screw the element clockwise into the tank, and tighten with the 1 1/2” socket wrench or element tool. Be sure O-ring seats properly.
NOTE: Repeat Steps 3 – 6 as Necessary for Multiple Elements
Step #8 – Open the main cold water inlet. If the water heater has been isolated from the system, open the valves. Refill the tank with cold water. Open a hot water faucet high in the system to bleed any air pressure from the system. Water will flow freely when air is completely.
Step #9 – Pressure check the tank for leaks around element. If no leaks are found, use a Phillips Head screwdriver to connect the wires to the element.
Step #10 – Turn power back on to the water heater.

Part 7 – Maintenance Considerations

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.

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 elements while the heater is in operation. If the elements are hissing / singing excessively, they may need to be cleaned. Inspect the elements 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.
