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 safety valve outlet. Piped down to safe point of disposal. Check local codes for maximum

distance from floor or allowable safe point of discharge.

• Pipe size be of equal to or greater than of safety valve outlet over entire length of discharge line.
• Have no intervening shutoff valve between safety 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 valve and discharge line.
• Install safety valve with spindle in vertical position.
• Do not install shutoff valve between boiler and safety valve.
• Support safety valve discharge piping.
• Be short and straight as possible.
• Terminate with plain end, not threaded.
• Constructed of material suitable for exposure to temperatures of 375° F (191°C); or greater.

Refer to local codes and appropriate ASME Boiler and Pressure Vessel Code for additional installation

requirements.
