TEMPERATURE AND PRESSURE RELIEF VALVE

CAUTION

TO REDUCE THE RISK OF EXCESSIVE PRESSURES AND TEMPERATURES IN THIS WATER HEATER, INSTALL TEMPERATURE AND PRESSURE PROTECTIVE EQUIPMENT REQUIRED BY LOCAL CODES BUT NOT 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 VALVE 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 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 will exit only within 6 inches above, or at any distance below, the structural floor and cannot contact any live electrical part. THE DISCHARGE OPENING MUST NOT BE BLOCKED OR REDUCED IN SIZE UNDER ANY CIRCUMSTANCES.
