BEFORE INSTALLING THE HOOD
1.
For the most efficient airflow exhaust use a straight run or as few elbows as possible. Vent unit to the outside
only.
2.
Two people are required for installation
Ducting
Always use rigid type metal ducts. Flexible ducts can restrict airflow by more than 50%.
6” round ductwork must be used to maintain maximum air flow efficiency with the 550 CFM motor.
Reduce the number of transitions and turns as much as possible. If a reducer is used, install a long reducer instead of a
pancake reducer. Reduce duct size as far away from the opening as possible. If turns and transitions are required install
them as far away from the opening as possible and as far apart between two as possible.
Here are some examples of different types of ventilation:
PREPARATION
Do not cut a joist or stud unless absolutely necessary. If a joist or stud must be cut then a supporting frame must be
constructed.
Before making cutouts make sure there is proper clearance within the ceiling or wall for exhaust vent.
