Placement in Crawl Space

Mount Crawl Space Ventilator inside the crawl space behind existing foundation ventilation openings. Ventilation openings shall be within three feet of each corner of the building.

 

Whenever possible when installing multiple ventilators, locate on opposite walls of the crawl space. This will provide a more even air exchange and cross-ventilation.

 

The air will take the path of least resistance. To prevent poor ventilation, close off vent openings close to ventilators.
