FIGURE1& The valve is certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment as meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22 and the code requirements of ASME. If replaced, the codes, but not pressure relief paragraph. valve must meet the requirements of local less than a combination temperature and valve certified as indicated in the above The valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (150 psi = 1,035 kPa) and a discharge capacity not less than the water heater input rate as shown on the model rating plate. For safe operation of the water heater, the relief valve must not be removed from its designated opening nor plugged. The temperature-pressure relief valve must be installed directly into the fitting of the water heater designed for the relief valve. Position the valve downward and provide tubing so that any discharge will exit only within 6 inches (153 ram) above, or at any distance below the structural floor, see Figure 16. Be certain that no contact is made with any live electrica! part. The discharge opening must not be blocked or reduced in size under any circumstances. Excessive length, over 30 feet (9.14 m), or use of more than four elbows can cause restriction and reduce the discharge capacity of the valve. No valve or other obstruction is to be placed between the relief valve and the tank. Do not connect tubing directly to discharge drain unless a 6 inch air gap is provided. To prevent bodily injury, hazard to life, or property damage, the relief valve must be allowed to discharge water in quantities should circumstances demand. If the discharge pipe is not connected to a drain or other suitable means, the water flow may cause property damage. Water Damage Hazard Temperature-pressure relief valve discharge pipe must terminate at adequate drain. The Discharge Pipe: * Shall not be smaller in size than the outlet pipe size of the valve, or have any reducing couplings or other restrictions. * Shall not be plugged or blocked. . Shall be of material listed for hot water distribution. . Shall be installed so as to allow complete drainage of both the temperature-pressure relief valve, and the discharge pipe. * Shall terminate at an adequate drain. * Shall not have any valve between the relief valve and tank. Water temperature over 125°F (52°0) can cause severe burns instantly resulting in severe injury or death Children, the elderly, and the physically or mentally disabled are at highest riskfor scald injury. Feel water before bathing or showering. Temperature limiting valves are available. Read instruction manual for safe temperature setting 14
