Power Venter discharge must be located how many feet from a building opening?

In the context of Maine's oil handling regulations, specific distances for venting systems, such as power venters, must be adhered to in order to ensure safety and compliance with local codes. The requirement to position a power venter discharge at least 4 feet from a building opening is primarily to prevent exhaust gases from entering the building. This distance helps mitigate the risks associated with carbon monoxide and other hazardous emissions, promoting safe air quality within the structure.

Proper placement is critical for maintaining ventilation efficiency, preventing backdrafting issues, and ensuring that exhaust does not interfere with other ventilation systems in the structure. The regulation reflects an understanding of airflow dynamics and the potential impact of exhaust on building inhabitants.
