What is the minimum distance that liquid fuel vent pipes should terminate from building openings?

The minimum distance that liquid fuel vent pipes should terminate from building openings is established to ensure safety and prevent the risk of fire or explosion. Terminating the vent pipes at least 2 feet from building openings helps to minimize the likelihood of vapors entering the structure. This distance acts as a buffer zone, mitigating potential hazards associated with the escape of fuel vapors.

Additionally, this requirement takes into account the potential for changes in air pressure near building openings, which could draw vapors inside if the vent pipes are positioned too close. By adhering to this guideline, the design seeks to safeguard the inhabitants of the building as well as maintain compliance with safety regulations set forth in the mechanical codes.
