" (20mm)
CSA Rated. Standard Models are self-closing T&P Relief Valves for Water
Heaters up to 105,000 BTU/Hr.
Watts Series LFSL100XL, LFL100XL , LFLL100XL and LFLLL100XL have
extended inlet shanks for use with the new generation of water heaters
containing extra thick insulation. These valves eliminate the use of an
extension nipple required with standard shank length models. They fea-
ture Lead Free* construction to comply with Lead Free* installation
requirements.
The combined 2-in-1 Temperature & Pressure relief valve provides the
least expensive and proven means for protection against both excessive
temperature and pressure emergency conditions.
Watts Self-closing combination T&P relief valves are design certified,
rated and listed by CSA to the requirements of ANSI Z21.22; and by the
National Board to the requirements of ASME Section IV.
They provide fully automatic temperature and pressure relief protection
for hot water storage tanks and heaters up to 105,000 BTU/Hr. The tem-
perature sensing element must be immersed in the water within the top
6" (152mm) of the tank. Male inlet and female outlet. Temperature relief
210°F (99°C). Standard setting 75, 100, 125, 150psi (5.3, 7.0, 8.8, 10.6 bar).

rated automatic temperature and pressure relief valve to protect the
heater from excessive pressure and excessive temperature. The device
shall be design certified, rated and listed by CSA to the requirements of
ANSI Z21.22; and by the National Board to the requirements of ASME
Section IV. The BTU discharge capacity of the device shall be in excess of
the BTU input rating of the heater. The Lead Free* Extended Shank T&P
Relief Valves shall comply with state codes and standards, where appli-
cable, requiring reduced lead content. Watts Series LFSL100XL,

WARNING: Following installation, the valve lever MUST be operated
AT LEAST ONCE A YEAR to insure that the waterways are clear.
Certain naturally occurring mineral deposits may adhere to the valve,
rendering it inoperative. When manually operating the lever, please take
precautions to avoid contact with hot water that may discharge and to
avoid water damage. 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 IMMEDIATELY.
This device is designed for emergency safety relief and shall not be used
as an operating control.
