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.
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.
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.
• 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.
