SECTION II: GENERAL INFORMATION (cont .)

ANODE RODS

The anode rod is used as a sacrificial element within the volume of the storage tank. The

purpose of the magnesium anode rod is to protect the inside of the tank against corrosion.

Anode rods should be inspected twice in the first year and at least yearly once a time interval

for inspection has been developed. Water conditions can influence the consumption rate of

the anode rods. Please see the Maintenance section of this manual for instructions on how to

change the anode rods.

Hydrogen gas is produced in a hot water system served by the heater that has not

been used for a long period of time (2 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. When 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.

TEMPERATURE AND PRESSURE RELIEF VALVE (T&P)

To reduce the risk of excessive pressures and temperatures in this water heater, install

temperature and pressure protective equipment required by local codes and no 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. This valve must be

marked with a maximum set pressure not to exceed the marked maximum working

pressure of the water heater. Install the valve in 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 circumstances.

Scalding injury and/or water damage can occur from either the manual lifting of the

lever or the normal operation of the T&P valve. If it is not piped to a proper drain.

If the valve fails to flow water or reseat, call your plumber.

The T&P valve is factory installed. A discharge drain tube must be installed (responsibility

of the installer) and shall terminate plain, not threaded, 6 inches above the floor drain.

The drain tube material must be approved for temperatures of 120

pressure of 150 PSI or greater.

BACKFLOW PREVENTER (CLOSED SYSTEM)

Some local municipal codes and ordinances require the use of these devices on potable

(domestic) water lines. Where backflow preventers are required, it will be necessary to install

a thermal expansion tank (designed for use with potable water) in order to prevent pressure

build up in the water heater and associated piping, which could cause the T&P

valve to discharge. Follow the expansion tank manufacturer's recommendations when

selecting a tank for your hot water system.

Note: Working pressure of the water heater is 150 PSI. Do not exceed 150 PSI.

SECTION III: PRE-INSTALLATION

LOCATION

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

connections, or the 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

location cannot be avoided, a suitable drain pan must be installed under the water

heater. The drain pan depth must be suitable for draining and collecting water. The

drain pan can be purchased from your plumbing professional. The drain pan must be

piped to an adequate drain and all drain piping must be at least 0.75" in diameter

and pitched for proper drainage.

DO NOT store or use gasoline or other flammable, combustible, or corrosive vapors

and/or liquids in the vicinity of the water heater or any other appliance.

IF YOU SMELL GAS:

• DO NOT try to light any appliance.

• DO NOT touch any electric switch; do not use any telephone in your building.

• Immediately call your gas supplier from a telephone in another building. Follow your

gas supplier's instructions.

• If you cannot reach your gas supplier, call the fire department.

DO NOT OPERATE THE APPLIANCE UNTIL THE LEAKAGE IS CORRECTED!

Do not drop water heater or lay heater down on its side. Move the water heater into

position by sliding or using an appropriately sized hand truck.
