Warning
. See Figure 2, Page 7 .
B. Discharge line pipe size shall be equal or greater
than that of relief valve outlet over entire length
of discharge line with no intervening shutoff valve
between safety relief valve and discharge to
atmosphere.
C. Discharge line shall terminate with plain end to
atmosphere where any discharge will be clearly
visible and is at no risk of freezing.
D. Discharge line shall be independently supported to
avoid applied stress on relief valve.
E. Installation shall allow complete drainage of relief
valve and discharge line.

INSTALLATION SYSTEM PIPING
WARNING
Burn or Scald Hazard. Discharge line shall be installed to relief valve outlet connection to avoid burns,
scalding, or water damage due to discharge of steam and/or hot water during operation.
Discharge line shall:
• connect to relief valve outlet and piped down to safe point of disposal. Check local codes for maximum
distance from
fl
oor or allowable safe point of discharge.
• be of pipe size equal to or greater than that of the relief valve outlet over the entire length of discharge
line;
• have no intervening shutoff valve between safety relief valve and discharge to atmosphere (do not plug or
place any obstruction in discharge line.
• terminate freely to atmosphere where any discharge will be clearly visible and at no risk of freezing;
• allow complete drainage of the valve and the discharge line;
• be independently supported and securely anchored to avoid applied stress on the relief valve;
• be as short and straight as possible;
• terminate with plain end (not threaded);
• be constructed of material suitable for exposure to temperatures of 375° F; or greater.
Refer to local codes and appropriate ANSI/ASME Boiler and Pressure Vessel Code, Section IV, or Boiler,
Pressure Vessel and Pressure Piping Code, CSA B51 for additional installation requirements.
