require the installation of your water heater be

accomplished in a way that the bottom element iselevated

from the floor at least 18 inches.

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. It is recommended that

a suitable drain pan be installed under the water heater

as shown below. This 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 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. Outside

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.

Water System Piping

Piping Installation

Piping, fittings, and valves should be installed according

to the installation drawing (Figure 6). If the indoor

installation area is subject to freezing temperatures, the

water piping must be protected by insulation.

Water supply pressure should not exceed 80% of the

working pressure of the water heater. The working

pressure is stated on the water heater's data plate. If

this occurs a pressure limiting valve with a bypass may

need to be installed in the cold water supply 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 fittings

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 fittings

Important: Always use a good grade of joint compound

and be certain that all fittings are drawn up tight

1 Install the water piping and fittings as shown in the

Figure 6 Connect the cold water supply (3/4 NPT)

to the fitting marked '%" Connect the hot water

supply (3/4 NPT) to the fitting marked "H"

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 unions in both the hot and cold

water supply lines are recommended for ease of

removing the water heater for service or replacement

3 The manufacturer of this water heater recommends

installing a tempering valve in the domestic hot water

line as shown in Figures 7 and 8 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

.Install a temperature and pressure relief valve and

discharge line 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 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

Please note the following:

DO NOT install this water heater with iron piping. The

system should be installed only with new piping that

issuitable for potable (drinkable) water such as copper,

CPVC, or polybutylene. DO NOT use PVC water

piping.

DO NOT use any pumps, valves, or fittings that are

not compatible with potable water.

DO NOT use valves that may cause excessive

restriction 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. Use 95/5 tin-antimony

or other equivalent material.

DO NOT tamper with the thermostat, heater elements,

electrical connections, or temperature and pressure

relief valve. Tampering voids all warranties. Only

qualified technicians 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

Periodic discharge of the temperature and pressure

relief valve may be due to thermal expansion in a closed

water supply system. The water utility supply meter may

contain a check valve, backfiow preventer or water

pressure reducing valve. This will create a closed water

system. During the heating cycle of the water heater,

the water expands causing pressure inside the water

heater to increase. This may cause the temperature

and pressure relief valve to discharge small quantities

of hot water. To prevent this from happening, there are

two recommendations:

Install a diaphragm-type expansion tank that is

suitable for potable water on the cold water supply

line. The expansion tank must have a minimum

capacity of 1.5 U.S. gallons for every 50 gallons

of stored water.

2. Install a 125 PSI pressure relief valve in the cold

water supply line. Make sure the discharge of

this valve is directed to an open drain and

protected from freezing.

Contact the local water supplier or plumbing inspector

for information on how to control this situation. Do not

plug the temperature and pressure relief valve.

For protection against excessive pressures and

temperatures, a temperature and pressure relief valve

must be installed in the opening marked "T & P RELIEF

VALVE" (See Figure 9).

Caution: To reduce the risk of excessive pressures and

temperatures in this water heater, install temperature

and pressure relief protective equipment required by

local codes, but no less than a combination temperature

and pressure relief valve certified 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

and Automatic Shutoff Devices for Hot Water Supply

Systems, ANSI Z21.22 - 1986. This valve must be marked

with the maximum set pressure not to exceed the marked

maximum working pressure of the water heater. Install

the valve into an opening provided and marked for this

purpose in the water heater, and orient it or provide

tubing so that any discharge from the valve exits only

within 6 inches above, or at any distance below, the

structural floor, and does not contact any live electrical

part. The discharge opening must not be blocked or

reduced in size under any circumstance.

Must not be in contact with any electrical part.

Must be connected to an adequate discharge line.

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 6 inches above a

floor drain or external to 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.

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. A tempering valve or other temperature limiting

valve must be installed in the water supply line to limit

the supply temperature to 120°F.

Note: Solar water heating systems can often supply

water with temperatures exceeding 180°F and may result

in water heater malfunction.

OPERATING YOUR WATER HEATER

Before operating the water heater, perform the

following:

1. Make sure the water heater has been properly

installed.

2. Completely fill the tank with water. (See Figure 2)

3. Apply power to the water heater only after the tank

is completely filled with water.

4. Carefully read and understand the "Water

Temperature Regulation" section of this manual.

5. Adjust the thermostat to the desired temperature

setting as directed under "Adjusting the Thermostat/

High Limit Control".

Important: Do not attempt to operate this water heater

if the thermostat(s), or surrounding insulation has been

exposed to water in any way. Immediately call a qualified

service technician to inspect the water heater and replace

any thermostat or insulation that has been exposed to

water. Do not attempt to repair these parts. Water heaters

subjected toflood conditions or any time the thermostat(s)

have been submerged in water require replacement of

the entire water heater.

Safety Shut=off

This water heater is designed to automatically shut-off

in the event that the water temperature exceeds 170°F

(77°C). A high limit control switch is used to shut off the

power to the elements if the water temperature exceeds

170°F (77°C). The high limit control can be reset by

firmly pushing in the red reset button located on the

thermostat. Follow the instructions under "Adjusting the

Thermostat/High Limit Control" to properly reset the high

limit control.

Water Temperature

Regulation

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 instructions manual before setting

temperature at water heater.

Feel water before bathing or showering.

Temperature limiting valves are available.

The thermostat is adjusted to a temperature setting of

120°F or lower when it is shipped from the factory.

Water temperature can be regulated by adjusting the

thermostat to the preferred setting as shown in "Adjusting

the Thermostat/High limit Control." The preferred

starting point is 120°F. There is a hot water scald

potential if the thermostat is set too high.

Important: Adjusting the thermostat past 120°F on the

thermostat will increase the risk of scald injury. Hot

water can produce first degree burns within:

120°F (49°C) more than 5 minutes

130°F (54°C) at 20 seconds

140°F (60°C) at 3 seconds

150°F (66°C) at 1-1!2 seconds

160°F (71°C) at less than 1 second

During low demand periods when hot water is not being

used, a lower thermostat setting will reduce energy

losses and may satisfy your normal hot water needs.

If hot water use is expected to be more than normal, a

higher thermostat setting may be required to meet the

increased demand.

When leaving your home for extended periods

(vacations, etc.) turn the thermostat to its lowest setting.

This will maintain the water at low temperatures with

minimum energy losses and prevent the tank from

freezing during cold weather.

Adjusting the Thermostat/High Limit Control

This water heater is equipped with one or more adjustable temperature regulating thermostats and a manual reset

high limit control. The following procedures must be performed when changing the temperature of the stored water

or resetting the high limit control. Upper and lower thermostats must be adjusted to the same temperature,

Before attempting to adjust the thermostat, make sure you read and understand the section of "Water

Temperature Regulation". Any other adjustments must be made by qualified service personnel.

1. Shut-off the power to the water heater.

2. Remove the access cover(s) and fold the insulation outward and away from the thermostat(s). Do not

remove the plastic cover.
