What should be the minimum height for steam safety termination above the roof?

The minimum height for steam safety termination above the roof is established for safety and efficiency reasons. When steam is released, it needs to disperse effectively to prevent any hazardous conditions or damage. A termination height of 7 feet is often deemed necessary to ensure that steam does not accumulate near the building's structure or neighboring areas, which could lead to safety concerns.

This height also considers factors like local building codes and the prevention of re-entry of steam back into the building, ensuring that the steam is safely vented away from windows, doors, and other openings. Furthermore, a termination point that is adequately elevated helps mitigate any potential nuisance from noise or steam contacting cooler surfaces, which can cause condensation.

By adhering to the specified 7 feet minimum height, the system ensures optimal performance, minimizes risks associated with steam discharge, and complies with safety standards commonly accepted in high-pressure piping practices.
