State SBD85 365NE A - Manual (Page 22)

22
This water heater is provided with a properly rated/sized and
certified combination temperature - pressure (T&P) relief valve by
the manufacturer. See Temperature-Pressure Relief Valve on pages
14-15 for information on replacement and other requirements.
Water Damage Hazard
Temperature-Pressure Relief Valve discharge
pipe must terminate at adequate drain.
•
CAUTION
Install a discharge pipe between the T&P valve discharge
opening and a suitable floor drain. Do not connect discharge
piping directly to the drain unless a 6” (15.2 cm) air gap is
provided. To prevent bodily injury, hazard to life, or property
damage, the relief valve must be allowed to discharge water
in adequate quantities should circumstances demand. If the
discharge pipe is not connected to a drain or other suitable
means, the water flow may cause property damage.
t&p ValVe discharge pipe reQuirements:
• 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 not be exposed to freezing temperatures.
• Shall be of material listed for hot water distribution.
• Shall be installed so as to allow complete drainage of both
Temperature-Pressure Relief Valve and the discharge pipe.
• Must terminate a maximum of six inches above a floor
drain or external to the building. In cold climates, it is
recommended that the discharge pipe be terminated at an
adequate drain inside the building.
• Shall not have any valve or other obstruction between the
relief valve and the drain.
