16 THERMAL EXP ANSION As water is heated,it expands (thermal expansion). In a closed system the volume of water will grow when it is heated. As the volume of water grows there will be a corresponding increase in water pressure due to thermal expansion.
17 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.
18 A gasline of sufcient sizemust be run to thewater heater . Consult thecurrentedition ofNationalFuel GasCode(ANSIZ223.1/NFP A 54) or the Natural Gas and Propane Installation Code (CAN/CSA B149.
