RE-INSPECTION OF T&P RELIEF VALVES: T&P valves should
be inspected AT LEAST ONCE EVERY THREE YEARS, and
replaced if necessary, by a licensed plumbing contractor or
qualied service technician to ensure that the product has not
been aected by corrosive water conditions and to ensure that
the valve and discharge line have not been altered or tampered
with illegally. Certain naturally occuring conditions may corrode
the valve and its components over time, rendering the valve
inoperative. Such conditions can only be detected if the valve
and its components are physically removed and inspected.
Do not attempt to conduct an inspection on your own.
Contact your plumbing contractor for a re-inspection to assure
continued safety.
FAILURE TO RE-INSPECT THE T&P VALVE AS DIRECTED
COULD RESULT IN UNSAFE TEMPERATURE AND/OR
PRESSURE BUILD-UP WHICH CAN RESULT IN PROPERTY
DAMAGE, SERIOUS PERSONAL INJURY, OR DEATH.
Do not thread a cap or plug into the relief valve or block relief
valve outlet line under any circumstances! Explosion and
property damage, serious injury, or death may result.
F. Scalding
An ASSE 1017 or ASSE 1070 temperature limiting or mixing
valve is recommended in installations servicing disabled or
elderly persons, or children. Mixing valves can reduce but do
not eliminate the risk of scalding.
To avoid scalding:
• Set the water heater set point temperature as low as
possible.
• Feel water before bathing or showering.
• If thermostatic valves are required, use devices
specically designed for such purpose. Install these
devices in accordance with instructions provided by
the manufacturer.
Failure to install a temperature limiting or mixing valve and
follow these instructions could result in property damage,
severe personal injury, or death due to scalds.
• Make certain that the drain valve is completely closed.
• Open the shut-o valve in the cold water supply line.
• Open the hot water faucets to allow air to vent from
the heater and piping.
• Allow sucient time for the heater to completely ll
with water.
• Verify elements are installed correctly. Check for leaks.
G. Filling the Heater
This water heater can deliver scalding water. Be careful
whenever using hot water to avoid scalding injury. Certain
appliances such as dishwashers and automatic clothes
washers may require increased water temperatures. By
setting the thermostat on this heater to obtain the increased
water temperature required by these appliances you may
create the potential for scald injury.
To protect against
injury, install a mixing
valve in the water
system. This valve
will reduce point
of use discharge
temperatures by
mixing cold and
hot water in branch
supply lines. Such
valves are available
from your local
plumbing supplier.
Table 1 details the
relationship of water
temperature and
time with regard to
scald injury and may
be used as a guide
in determining the
safest water temperature for your applications.
To avoid water damage or scalding due to relief valve operation:
• Discharge line must be connected to relief valve outlet
and run to a safe place of disposal. Terminate the
discharge line in a manner that will prevent possibility of
severe burns or property damage should the relief valve
discharge.
• Discharge line must be as short as possible and the same
size as the valve discharge connection throughout its
entire length.
• Discharge line must pitch downward from the valve
and terminate at least 6” above the oor drain, making
discharge clearly visible.
• The discharge line shall terminate plain, not threaded,
with a material serviceable for temperatures of 375
o
F or
greater.
• Do not pipe discharge to any location where freezing
could occur.
• No valve may be installed between the relief valve and
heater or in the discharge line. Do not plug or place any
obstruction in the discharge line.
• Test the operation of the relief valve after lling and
pressurizing the system by lifting the lever. Make sure
the valve discharges freely. If the valve fails to operate
correctly, immediately replace with a new properly rated
relief valve.
• Test T&P valve at least once annually to ensure the
waterway is clear. If valve does not operate, turn the
heater “o” and call a plumber immediately.
• Take care whenever operating relief valve to avoid
scalding injury or property damage.
FAILURE TO COMPLY WITH THE ABOVE GUIDELINES
COULD RESULT IN FAILURE OF RELIEF VALVE OPERATION,
RESULTING IN POSSIBILITY OF SUBSTANTIAL PROPERTY
DAMAGE, SEVERE PERSONAL INJURY, OR DEATH.
