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 floor drain, making
discharge clearly visible.
•
The discharge line shall terminate plain, not threaded, with
a material serviceable for temperatures of 375
•
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 filling 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 "off" and
call a plumber immediately.
•
Take care whenever operating relief valve to avoid scalding
injury or property damage.
FAILURE TO COMPLY WITH THESE 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 qualified service
technician to ensure that the product has not been affected 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 specifically
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
o
F or greater.
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
water temperatures. By
setting
the
on this heater to obtain
the
increased
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.

temperature and time with
regard to scald injury and may be used as a guide in determining the
safest water temperature for your applications.
G. Filling the Heater
•
Make certain that the drain valve is completely closed.
•
Open the shut-off valve in the cold water supply line.
•
Open the hot water faucets to allow air to vent from the heater
and piping.
•
Allow sufficient time for the heater to completely fill with
water.
•
Verify elements are installed correctly. Check for leaks.
When filling the water heater, open a hot water tap to release air
in the tank and piping. The tank must be full of water before the
heater is turned on. Failure to ensure the water heater is full before
turning it on could result in damage to the water heater and other
property damages. Such damages ARE NOT covered by water heater
warranty.
