POP VENT/AURA VENT/SOLAR FAN/ROUND BACK VENT
PLACEMENT INSTRUCTIONS
FOR ROOF EXHAUST APPLICATIONS

The following is our recommendation for the proper placement of the PV, AV, ASF & RBV lines.

The vent should be placed approx. 8" - 10" down from the peak.

On homes that require two vents, they should be placed approx. 1/4 of the total length in from each end.
 
On homes that require three vents, one vent should be in the center and the other two approx. 1/6 in from each end.
 
On homes that require four vents, two vents should be placed approx. 1/8 in from each end and two vents should be placed approx. 3/8 in from each end.
 
When ventilating, calculate 50% exhaust from above, and 50% inlet from below. One 14" vent is good for approx. 600 sq. ft. One 12" vent is good for 450 sq. ft., one 10” vent is good for 327 sq. ft., and one 8” vent is good for 200 sq. ft., etc.
