Model fl has a mounting flange for easy installation.
Vent in brick wall.
Brick vents are ideal for crawl space between floor or bath exhaust.
In this case the drainage and ventilation of this large brick wall is left to 30 small weep holes spaced at 2 foot intervals along the bottom course of the wall.
Air is pulled in through one side of the home and exits the opposite side.
If you place them further up the wall you may find the draft inside the home to be excessive and there are better options to consider.
The surface area of the wall is approximately 1100 square feet while the total surface area of all the weep holes together is 18 square feet.
These sturdy vents make an attractive accent through brick or block walls but are equally useful through any wall type.
Always wear safety glasses.
