Specifications
T&P valves
Each water heater and hot water storage tank shall be equipped
with a CSA and A.S.M.E. Rated** automatic temperature and
pressure relief valve to protect the heater from excessive pres-
sure and temperature. Lead Free* Temperature and Pressure
Relief Valves (valve type, reduced pressure zone, etc.) shall
be constructed using Lead Free* materials. Lead Free valves
shall comply with state codes and standards, where applicable,
requiring reduced lead content. The device shall be ANSI Z21.22
certified. The BTU discharge capacity of the device shall be in
excess of the BTU input rating of the heater. Watts Series No.

NOTICE
Inquire with governing authorities for local installation
requirements
*The wetted surface of this product contacted by consumable
water contains less than 0.25% of lead by weight.
Following installation, the valve lever MUST be operated
AT LEAST ONCE A YEAR to ensure that the water-ways
are clear. Certain naturally occurring mineral deposits may
adhere to the valve, rendering it inoperative. When manually
operating the lever, water will discharge and precautions must be
taken to avoid contact with hot water and to avoid water dam-
age. BEFORE operating lever, check to see that a discharge
line is connected to this valve directing the flow of hot water from
the valve to a proper place of disposal otherwise personal injury
may result. If no water flows, valve is inoperative. TURN OFF
THE WATER HEATER AND CALL A PLUMBER IMMEDI-
ATELY.
This device is designed for emergency safety relief and shall not
be used as an operating control.
