corrosive vapors and liquids in the vicinity of this or any other appliance.

General Information continued-

A sacrificial anode(s) is used to extend tank life. Removal of any anode,

except for inspection and/or replacement, will nullify the warranty. In

areas where water is unusually active, an odor may occur at the hot water

faucet due to a reaction between the sacrificial anode and impurities in the

water. If this should happen, an alternative anode(s) may be purchased

from the supplier that installed this water heater. This will minimize the

odor while protecting the tank. Additionally, the water heater should be

flushed with appropriate dissolvers to eliminate any bacteria.

INSTALLATION

Locating the Water Heater

This water heater MUST be installed indoors out of the wind and

weather.

This water heater shall NOT be installed in any location where gasoline

or flammable vapors are likely to be present, unless the installation is

such to eliminate the probable ignition of gasoline or flammable

vapors.

The location this water heater is to be installed is of utmost importance.

Before installing this water heater, consult the installation section of these

instructions. After reading these installation and operating instructions,

select a location for the water heater where the floor is level and is easily

accessible to a power supply and water connections. It is recommended

that the water heater be located near the center of greatest hot water

usage to prevent heat loss through the pipes.

DO NOT locate the water heater where water lines could be subjected

to freezing temperatures. Locate the water heater so that access

panels and drain valves are accessible.

IMPORTANT

Before proceeding, please inspect the water heater and its components

for possible damage. DO NOT install any damaged components. If

damage is evident, please contact the supplier where the water heater

was purchased or the manufacturer listed on the rating plate for

replacement parts.

WARNING

Water heaters are heat producing appliances. To avoid damage or injury,

there shall be no materials stored against the water heater and proper

care shall be taken to avoid unnecessary contact (especially by children)

with the water heater. UNDER NO CIRCUMSTANCES SHALL FLAMMABLE

MATERIALS, SUCH AS GASOLINE OR PAINT THINNER BE USED OR

STORED IN THE VICINITY OF THIS WATER HEATER OR ANY LOCATION

FROM WHICH FUMES COULD REACH THE WATER HEATER.

Locating the Water Heater continued-

Some models are not equipped with a drain valve. For those models,

install a drain tee in the cold-water inlet as close as practical to the

water heater.

Water heater corrosion and component failure can be caused by the

heating and breakdown of airborne chemical vapors. Examples of

some typical compounds that are potentially corrosive are: spray can

propellants, cleaning solvents, refrigerator and air conditioning

refrigerants, swimming pool chemicals, calcium or sodium chloride,

waxes and process chemicals. These materials are corrosive at very

low concentration levels with little or no odor to reveal their presence.

NOTE: DAMAGE TO THE WATER HEATER CAUSED BY EXPOSURE TO

CORROSIVE VAPORS IS NOT COVERED BY THE WARRANTY. DO NOT

OPERATE THE WATER HEATER IF EXPOSURE HAS OR WILL OCCUR.

DO NOT STORE ANY POTENTIALLY CORROSIVE COMPOUNDS IN THE

VICINITY OF THE WATER HEATER.

This water heater must be located in an area where leakage of the tank

or water line connections and the combination temperature and

pressure relief valve will not result in damage to the area adjacent to

the water heater or to lower floors of the structure. When such

locations cannot be avoided, a suitable drain pan must be installed

under the water heater. The drain pan must have a minimum length

and width of at least 4 in. (10.2 cm) greater than the diameter of the

water heater. The drain pan, as described above, can be purchased

from your plumbing professional. The drain pan must be piped to an

adequate drain. The piping must be pitched for proper drainage.

CLEARANCES

1. Minimum clearance to combustible material is 0 inches for the Top,

Sides, Front, and Rear of this water heater. However, it is

recommended that at least 18 inches (45.7 cm) from the Top, and

24 inches (61 cm) from the Front. Clearance for servicing may be

reduced down to minimum clearance to combustible material, but

service time and effort may be greatly increased.

2. Increase distances to provide clearances for servicing.

To comply with NSF requirements this water heater is to be:

a) Sealed to the floor with sealant, in a smooth and easily

cleanable way, or

b) Installed with an optional leg kit that includes legs and/or

extensions that provide a minimum clearance of 6” beneath the

water heater.

Locating the Water Heater continued-

Note: Per Section 507.2 Seismic Provisions of the 2021 Uniform

Plumbing Code (UPC). Water heaters shall be anchored or strapped to

resist horizontal displacement due to earthquake motion. Strapping

shall be at points within the upper one-third and lower one-third of its

vertical dimensions. At the lower point, a distance of not less than 4

inches shall be maintained from the controls with the strapping.

Please refer to the local authority having jurisdiction to see if there are

any additional local requirements regarding seismic provisions.

Water Connections

NOTE: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE

MAIN WATER SUPPLY VALVE.

After shutting the main water supply valve, open a faucet to relieve the

water line pressure to prevent any water from leaking out of the pipes

while making the water connections to the water heater. After the

pressure has been relieved, close the faucet. The COLD water inlet and

HOT water outlet are identified on top of the water heater. The fittings

at the cold-water inlet and hot water outlet are dielectric waterway

fittings with 3/4” NPT tapered male threads. Make the proper

plumbing connections between the water heater and the plumbing

system in the house. Install a shut-off valve in the cold-water supply

line.

If this water heater is installed in a closed water supply system, such as

the one having a back-flow preventer in the cold-water supply,

provisions shall be made to control thermal expansion. DO NOT

operate this water heater in a closed system without provisions for

controlling thermal expansion. Your water supplier or local plumbing

inspector should be contacted on how to control this situation.

CAUTION

If sweat fittings are to be used, DO NOT apply heat to the nipples on top

of the water heater. Sweat the tubing to the adapter before fitting the

adapter to the water connections. It is imperative that heat is not applied

to the nipples containing a plastic liner.

IMPORTANT

FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED 3/4” X 3/4”

TEMPERATURE-PRESSURE RELIEF VALVE WILL RELEASE THE

MANUFACTURER FROM ANY CLAIM WHICH MIGHT RESULT FROM

EXCESSIVE TEMPERATURE AND PRESSURES.

Water Connections continued-

After installation of the water lines, open the main water supply valve

and fill the water heater. While the water heater is filling, open several

hot water faucets to allow air to escape from the water system. When

a steady stream of water flows through the faucets, close them and

check all water connections for possible leaks. NEVER OPERATE THE

WATER HEATER WITHOUT FIRST BEING CERTAIN IT IS FILLED WITH

WATER.

WARNING

For protection against excessive temperatures and pressure, install

temperature and pressure protective equipment required by local codes,

but not less than a combination temperature and pressure relief valve

certified by a nationally recognized testing laboratory that maintains

periodic inspection of production of listed equipment or materials, as

meeting the Requirements for Relief Valves and Automatic Gas Shutoff

Devices for Hot Water Supply Systems, ANSI Z21.22, and the Standard

CAN1-4.4 Temperature, Pressure, Temperature and Pressure Relief

Valves and Vacuum Relief Valves. The combination temperature and

pressure relief valve shall be marked with a maximum set pressure, not to

exceed the maximum working pressure of the water heater. The

combination temperature and pressure relief valve shall also have an

hourly rated temperature steam BTU discharge capacity not less than the

hourly input rating of the water heater.

Install the combination temperature and pressure relief valve into the

opening provided and marked for this purpose on the water heater

Note: Some models may already be equipped or supplied with a

combination temperature and pressure relief valve. Verify that the

combination temperature and pressure relief valve complies with local

codes. If the combination temperature and pressure relief valve does not

comply with local codes, replace it with one that does. Follow the

installation instructions above on this page.

Install a discharge line so that water discharged from the combination

temperature and pressure relief valve will exit within six (6) inches (15.3

cm) above, or any distance below the structural floor and cannot contact

any live electrical part. The discharge line is to be installed to allow for

complete drainage of both the temperature and pressure relief valve and

the discharge line. The discharge opening must not be subjected to

blockage or freezing. DO NOT thread, plug or cap the discharge line. It is

recommended that a minimum of four (4) inches (10.2 cm) be provided on

the side of the water heater for servicing and maintenance of the

combination temperature and pressure relief valve.

Do not place a valve between the combination temperature and pressure

relief valve and the tank.

Water Connections continued-

This water heater can deliver scalding temperature water at any faucet

in the system. Be careful whenever using hot water to avoid scalding

injury. Certain appliances, such as dishwashers and automatic clothes

washers, may require increased temperature water. By setting the

thermostat on this water heater to obtain increased temperature water

required by these appliances, you may create the potential for scald

injury. To protect against injury, you

should install an ASSE approved mixing

valve in the water system. This valve

will reduce point of discharge

temperature by mixing cold and hot

water in branch supply lines. Such

valves are available from the

manufacturer of this water heater or a

local plumbing supplier. Please consult

with a plumbing professional.

WARNING

Hydrogen gas can be produced in a hot water system served by this

water heater that has not been used for a long period of time (generally

two weeks or more). Hydrogen gas is extremely flammable. To reduce

the risk of injury under these conditions, it is recommended that the hot

water faucet be opened for several minutes at the kitchen sink before

using any electrical appliance connected to the hot water system. If

hydrogen is present, there will probably be an unusual sound such as

air escaping through the pipe as the water begins to flow. There should

be no smoking or open flame near the faucet at the time it is open.

CAUTION

INCREASING THE THERMOSTAT SETTING ABOVE THE PRESET

TEMPERATURE MAY CAUSE SEVERE BURNS AND CONSUME

EXCESSIVE ENERGY. HOTTER WATER INCREASES THE RISK OF

SCALD INJURY.

Water Connections continued-

Upright Models (See Figures 1A & 1B)

The hot and cold-water connections are identified on the top of the

water heater (See figure 1A). For bottom inlet models, the cold-water

inlet is located on the side of the drain valve (see figure 1B). Connect

the hot and cold-water lines to the installed nipples using unions.

Install a listed temperature-pressure relief valve in the opening on the

side of the water heater.
