Cooking fumes and smoke dissipates 
before it reaches the blower.

Use a damper type sidewall cap.
Reduce the number of elbows and length of duct work.
Check if all joints are properly connected, sealed and 
taped.

Check if unit is installed at the recommended height 
(page 9).  The range hood should also be able to cover 
the entire cooking area from left to right and most areas 
from rear to front.
Open doors and windows might also distract air flow 
before it reaches the blowers.
Make sure blowers are on high speed for heavy cooking.
