Water Damage Hazard

pipe must terminate at adequate drain.

VALVE
COLD
No valve or other obstruction is to be placed between the relief
valve and the tank. Do not connect tubing directly to discharge
drain unless a 6 inch air gap is provided. To prevent bodily
injury, hazard to life, or property damage, the relief valve must
be allowed to discharge water inquantities should circumstances
demand. Ifthe discharge pipe is not connected to a drain or other
suitable means, the water flow may cause property damage.
The Discharge Pipe:
• Shall not be smaller in size than the outlet pipe size of the
valve, or have any reducing couplings or other restrictions.
• Shall not be plugged or blocked.
• Shall be of material listed for hot water distribution.
• Shall be installed so as to allow complete drainage of both the
temperature-pressure relief valve, and the discharge pipe.
• Shall terminate at an adequate drain.
• Shall not have any valve between the relief valve and tank.

Water temperature over 125°F
(52°C) can cause severe burns
instantly resulting insevere injury
or death.
Children, the elderly, and the
,_ physically or mentally disabled
. are at highest riskfor scald injury.
_,,_, Feel water before bathing or
_ 1_ showering.
Temperature limiting valves are
available.
Read instruction manual for safe
temperature setting
The temperature-pressure relief valve must be manually operated
at least once a year. Caution should be taken to ensure that
(1) no one is in front of or around the outlet of the temperature-
pressure relief valve discharge line, and (2) the water manually
discharged wilt not cause any bodily injury or property damage
because the water may be extremely hot.
If after manually operating the valve, it fails to completely reset
and continues to release water, immediately close the cold water
inlet to the water heater, follow the draining instructions, and
replace the temperature-pressure relief valve with a new one.

Temperature-Pressure Relief Valve -
Optional Location
An optional temperature-pressure relief valve location is provided
on the jacket top.
If the top location is preferred, the temperature-pressure relief
valve in the side location and the counter-sunk plug in the top
location can be interchanged.
Be sure to use new pipe joint compound or put two to three turns
of teflon tape around the threaded ends of the temperature-
pressure relief valve and counter-sunk plug when reinstalling
these parts.
