What is the minimum height requirement for a main vent from the nearest connected appliance?

The minimum height requirement for a main vent from the nearest connected appliance is 5 feet. This regulation is based on ensuring that the gases expelled through the vent are safely above the reach of any potential conflicts with other infrastructures or areas where people might congregate.

Maintaining this height helps to prevent the re-entry of flue gases into the building, thereby improving safety for occupants. It also allows for proper dispersion of these gases into the atmosphere, minimizing health risks and ensuring compliance with building codes and standards concerning ventilation and flue systems.

Understanding this requirement is crucial for anyone working with heating systems, as non-compliance can lead to serious hazards, including carbon monoxide buildup and potential fire risks.
