RE: Ex Parte Communication, Docket EERE-2012-BT-STD-0022

To whom it may concern,

On November 16, 2012, representatives from PJM Interconnection LLC, National Rural Electric Cooperatives Association, Edison Electric Institute, American Public Power Association, Rheem and the Steffes Corporati on (together, “Joint Commenters”) met with members of the Department of Energy (“Department”) to discuss the request for information “[...] Energy Conservation Standards for Resi dential Water Heaters”, the comments filed therein, and follow-up items from a previous meeting on September 5, 2012. See below for complete attendee list.

The main purpose of this meeting was to review research that Joint Commenters had done with water heater manufacturers to identify technology solutions, and their feasibility and cost, to enable electric storage water heaters to be grid-enabled at the point of manufacture. Every water heater manufacturer that the Joint Commenters spoke with was not only supportive of the idea, but in most cases was already developing such a device for the water heater. As an example, Joint Commenters presented a manual for the Whirlpool ‘Energy Smart’ water heater, which has grid-enabling features that allow for its control by utilities or the customer (see attachment).

The meeting adjourned with the Department asking Joint Commenters to think about ways in which utilities could routinely report the number of grid-enabled water heaters enrolled in their respective demand response programs and Joint Commenters agreed to file reporting options as additional comments in the docket.

Sincerely,

/s/ Scott Baker, on behalf of Joint Commenters

# 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.

The water heater should be located in an area not subject to freezing temperatures. Water heaters locatedin unconditioned spaces (i.e., attics, garages, basements, etc.) may require the water piping and drain piping to be insulated to protect against freezing. Thedrain 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: 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.

NOTE: The water heater shall be located so it is not subject to physical damage by moving vehicles or area flooding.

State of California
NOTE: The water heater must be braced, anchored, or strapped to avoid moving during an earthquake. Contact local utilities for code requirements in your area or call 1-877-817-6750 and request instructions.5 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 compound 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. In a Closed System use a Thermal Expansion Tank.

# Water System Piping Piping Installation
Piping, fi ttings, and valves should be installed accordingto the installation drawing (Figure 3). If the indoor installation area is subject to freezing temperatures, the water piping must be protected by insulation.6 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 quali fi 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 wateris 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. Thermalexpansion can also cause intermittent temperaturepressure relief valve operation: water discharged from thevalve 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 agencyor your retail supplier regarding the installation of a thermal expansion tank.

°F/°C F

For protection against excessive pressures and temperatures, a temperature and pressure relief valve must be installed in the opening marked “T&P RELIEFVALVE” (See Figure 5). This valve must be design certifi 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 theevent 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. 

### 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.

IMPORTANT: Do not plug or remove the temperature and pressure relief valve (T&P valve).7 

### The Temperature & Pressure Relief Valve:

• Must be connected to an adequate discharge line.

• Must not be in contact with any electrical part.

• Must not be rated higher than the working pressure shown on the data plate of the water heater. 

### The Discharge Line:

• Must not be smaller than the pipe size of the relief valve or have any reducing coupling installed in the discharge line.

• Must not be capped, blocked, plugged, or contain any valve between the relief valve and the end of the discharge line.

• Must terminate a maximum of six inches above a fl oor drain or external to the building. In cold climates, it is recommended that the discharge pipe be termi- nated at an adequate drain inside the building.

• Must be capable of withstanding 250° F (121° C) without distortion.

• Must be installed to allow complete drainage of both the valve and discharge line.


### T&P Relief Valve and Pipe Insulation:
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. 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.

# The Electronic Thermostat IMPORTANT: The Energy Smart ®

Module (ESM) must be removed before attempting to access the thermostat.NOTE: for the Electronic Thermostat (ET) changes to remain in effect the Energy Smart ®

Module (ESM) must notbe reconnected, also read the “Water Temperature Regulation” under the “Operating Your Water Heater” section. If the instructions are not clear, contact a quali fi ed person.
The Energy Smart ®

Module (ESM) is intended to serve as the primary interface for operating the water heater; however, the Electronic Thermostat (ET) may control the water heater in the absence of the Energy Smart ®

Module (ESM).

The Electronic Thermostat consists of an electronics box that contains a low voltage power supply, the thermostat set point knob, relays to switch between the upper andlower heating elements, one control thermistor, a connector for the lower element control thermistor, microelectronics to convert the thermistor signals and perform switching and other logic functions, and a connector to tie the Electronic Thermostat (ET) to the Energy Smart ®

Module (ESM) located on the front of the water heater jacket. The majority of the self-diagnostics are located in the Electronic Thermostat (ET), including the dry- fire protection intelligence. The thermostat circuit is designed so that when the upper heating element calls for heat, the power is directed to that element even if the lower element is also calling for heat. 

## Diagnostic LED LightThe Green/Red LED light indicates the status of the electronic thermostat (See Figure 10A).



## • Green LED will signal normal operation. The green LED will blink 2 times per second to indicate that power is applied to the upper heating element and at a faster rate(4 times per second) to indicate that the lower heating element is powered.



## • Red LED will fl ash error codes. If a fault is detected by the electronic thermostat, the LED light indicator will use the red LED to indicate the fault detected. The fl ash code sequence is to consist of 1/2 second fl ashes of the red LED each separated by a 1/2 second off period.

The number of fl ashes indicates the fault code number. (See diagnostic code chart section in this manual). After the last 1/2 second “on” period, the LED will remainoff until a total of 5 seconds has elapsed for the fault indication cycle (there is a 5 seconds delay before the fault fl ash pattern repeats). After the 5 seconds are completed, the fault indication cycle is repeated starting with the fi rst 1/2 second- fl ash. The fl ash sequence will be repeated as long as the fault remains. Only one fault can be declared at a time. NOTE: the green LED is turned off when a fault code is being displayed, even though the heater may be operating in limp mode with an element on. See diagnostic code chart section in this manual. 

## Overriding The Energy Smart ® 

## Module (ESM) If the Energy Smart ®

Module (ESM) is not working, simply unplug the interface module and turn the set point knobon the Electronic Thermostat (ET) to the desired temperature (See Figures 10A & 10B).

# Smart Grid Technology

The electric Smart Grid will enable signi fi cant improvements in electric power reliability and quality through reduction of peak power demand, while providing consumers the knowledge and ability to manage their energy consumption and utility costs.

According to the Department of Energy (DOE), since 1982 the growth in peak electricity demand has exceeded power transmission growth. This has caused more frequent blackouts and service interruptions, as well as an increase in the costly reserve capacity the power grid requires to meet higher peak demands. The increased demand for electrical power across the nation has also led to higher peak utility costs. Smart appliances are one way to help mitigate this problem. By using advanced digital communication technologies, smart appliances will be able to communicate with local power company or home energy management systems, and react accordingly to save energy and money. For example, during peak demand periods the water heater may pause or delay its power consumption and thus reduce the load on the smart utility grid. Additionally, smart appliances will also communicate with consumers to let them know how much energy they are consuming. This will eventually allow consumers to control their appliances, manage energy usage, and to ultimately save money.



## Smart Grid Control (Where Available)

Where available, Grid Communication Adaptors may be supplied by the local power company or purchased fromleading retailers. Please contact your local power company for more information.

To activate Smart Grid Control, remove the cover overthe grid connection pins and plug in the grid communication adaptor. See Figure 10C. NOTE: use only Whirlpool - approved grid communication adaptors. This will enable the power company to communicate the peak demand periods for the water heater’s power usage.
After this connection has been made, simply press the “Grid Enabled” button to enable and/
or disable a request for grid control. See Figure 10D. Enabling this feature will allow acceptanceof the power company communication of grid management requests. Disabling this feature will allow the water heater to ignore grid management requests.

NOTE: Smart Grid will be disabled when the Energy Smart ®

Module (ESM) is disconnected from the junction box wiring harness (see page 12). Figure 10 D Smart Grid Contro l

# WARNING14 

# Operational Conditions

Anode Rod/Water Odor

Each water heater contains at least one anode rod, which will slowly deplete (due to electrolysis) prolonging the life of the water heater by protecting the glass-lined tank from corrosion. Adverse water quality, hotter watertemperatures, high hot water usage, hydronic heating devices, and water softening methods can increase the rate of anode rod depletion. Once the anode rod is depleted, the tank will start to corrode, eventually developing a leak.
Certain water conditions will cause a reaction between the anode rod and the water. The most common complaint associated with the anode rod is a “rotten egg smell” produced from the presence of hydrogen sul fide gas dissolved in the water. CAUTION: Do not remove this rod permanently as it will void any warranties. A special anode rod may be available if water odor or discoloration occurs. NOTE: this rod may reduce but not eliminate water odor problems. The water supply system may require special fi ltration equipment from a water conditioning company to successfully eliminate all water odor problems.

Arti ficially softened water is exceedingly 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. The anode rod should be inspected after a maximum of three years and annually thereafter until the condition of the anode rod dictates its replacement. NOTE: arti fi cially softened water requires the anode rod to be inspected annually. The following are typical (but not all) signs of a depleted anode rod: • The majority of the rods diameter is less than 3/8”. • Signi fi cant sections of the support wire (approx. 1/3 or more of the anode rod’s length) are visible.
If the anode rod show signs of either or both it should be replaced (see Figure 11). NOTE: Whether re-installing orreplacing the anode rod, check for any leaks and immediately correct if found. 

## Water Heater Sounds
During the normal operation of the water heater, sounds or noises may be heard. These noises are common and may result from the following:
1. Normal expansion and contraction of metal parts during periods of heat-up and cool-down.
2. Sediment buildup in the tank bottom will create varying amounts of noise and may cause premature tank failure. Drain and fl ush the tank as directed under “Draining and Flushing”.


## Stacking
Certain water usage patterns can cause the water temperature to exceed the thermostat setting. This is known as “Stacking”.
Stacking occurs when a series of short draws of hot water (3 gallons or less) are taken from the water heatertank. This causes increased cycling of the heater elements and can result in increased water temperatures at the hot water outlet. An anti-scald device is recommended in the hot water supply line to reduce the risk of scald injury. Use of a mixing valve is encouraged.

Figure 11 Anode Rod

EXPOSED SUPPORT WIRE PITTED ANODE ROD

EXPOSED SUPPORT WIRE

See “Replacing the Anode Rod” in the maintenance section page 15.15 Manually operate the temperature and pressure relief valve at least once a year to make sure it is working properly. To prevent water damage, the valve must be properly connected to a discharge line which terminates at an adequate drain. Standing clear of the outlet (discharged water may be hot), slowly lift and release the lever handle on the temperature and pressure relief valve to allow the valve to operate freely and return to its closed position. If the valve fails to completely reset and continues to release water, immediately disconnect the electrical power, close the cold water inlet valve and call a quali fi ed person. 

# MAINTENANCE OF YOUR WATER HEATER

Draining and Flushing

It is recommended that the tank be drained and fl ushed every 6 months to remove sediment which may buildup during operation. The water heater should be drained if being shut down during freezing temperatures. To drain the tank, perform the following steps:
1. T urn off the power to water heater.
2. Open a nearby hot water faucet until the water is no longer hot. 3. Close the cold water inlet valve.
4. Connect a hose to the drain valve and terminate it to an adequate drain or external to the building.
5. Open the water heater drain valve and allow all the water to drain from the tank. Flush the tank with water as needed to remove sediment. 6. Close the drain valve and re fi ll the tank (open the cold water inlet valve), and restart the heater as directed in this manual. CAUTION: Do not turn on power to the water heater unless it is completely fi lled with water. To ensure that the tank is full, open a hot water f aucet and allow water to run until the air is purged and the water fl ows uninterrupted from the faucet.
7. Turn the electrical power on to turn the water heater
on. NOTE: the water heater will conduct a system diagnostic prior to operation.If the water heater is going to be shut down for an extended period, the drain valve should be left open. 

# Replacing the Anode Rod

1. Turn off the power to the water heater. 2. Shut off the water supply and open a nearby hot water faucet to depressurize the water tank.
3. Drain approximately 5 gallons of water from the tank. (Refer to “Draining and Flushing” for proper procedures.) Close drain valve.
4. Remove the old anode rod (See Figure 11). 5. Use Te fl on ® tape or approved pipe sealant on threads and install new anode rod. 6. Turn on the water supply and open a nearby hot water faucet to purge all air from the water system.
7. Restart the heater as directed in this manual. Turn the electrical power on to turn the water heater on. NOTE: the water heater will conduct a system diag- nostic prior to operation. See the “Repair Parts Illus- tration” for anode rod location on page 22.

# WARNING

Replacement heating elements must be of the same style and voltage/wattage rating as the ones originally in the water heater. This information can be found on the fl ange or terminal block of the element or on the water heater data plate. 1. Turn off the electric power to the water heater.
2. Drain the water heater as directed under “Draining and Flushing” section. 3. Remove the access cover(s), then remove the insula- tion and element cover(s). Remove the plastic guard covering electric wiring.
4. Disconnect the electric wires from the heating element (See Figure 13). Remove the screw-in element by turning the element counterclockwise with an SAE 1- 1/ 2 inch socket wrench or use an ele- ment wrench. Remove the existing gasket.

5. Clean the area with a soft cloth to remove any debris where the gasket fi ts to the tank. If replacing the bot- tom element, remove the accumulated sediment on the bottom of the tank. Refer to “Draining and Flush- ing.” 6. Make sure the replacement element has the correct voltage and wattage rating. Lubricate the new gasket with a few drops of dishwashing soap, position the new gasket on the element and insert it into the water heater tank (See Figure 14). Tighten the element by turning it clockwise until secure.
