SECTION II: GENERAL INFORMATION (cont .)

ANODE RODS

The anode rods are used as sacrificial elements within the volume of the storage tank.  The 

purpose of the rods 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 will 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 in your water heater.

CAUTION 

   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)

CAUTION 

  

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.

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°F or greater and a 

pressure of 150 PSI or greater.

BACKFLOW PREVENTER (CLOSED LOOP 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 

thermal expansion tank

 (designed for used 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.
