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.
Do not thread a cap or plug into the relief valve or relief valve
line under any circumstances! Explosion and property damage,
serious injury, or death may result.
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.
F. Scalding
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 4 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.
An ASSE 1017 or ASSE 1070 temperature limiting or mixing
valve is recommended in installations servicing disabled or
elderly persons, or children. Mixing valves 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.
The water heater must be full of water and the system fully
purged BEFORE powering the water heater. When lling the
water heater, open a hot water tap to release air in the tank
and piping. All air has been purged from the system when
water runs freely from the faucets.
Applying power to the water heater when it is not full of water
will damage the heat exchanger, and could result in property
damage, serious personal injury, or death. Such damages
ARE NOT covered by water heater warranty.

Table 4 - Approximate Time / Temperature Relationships in Scalds
• Make certain 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.
G. Filling the Heater
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.
