EXHAUST HOOD CONFIGURATION
You can mount the hood exhaust fan on the exterior wall or in
line with the hood exhaust duct.
If necessary, you can mount the exhaust pipe further into the
hood or even into the exhaust duct at the top of the hood. This
should only be done, however, if the hood exhaust fan capacity
is insufficient to draw all the smoke out of the hood.
If you move the exhaust pipe close to or inside the hood exhaust
duct, you must ensure that there is minimal draw of air through
the unit. Measure the airflow lift and adjust the louvers as
applicable. (The ideal range is between -2.5 and -3.5 grams.)
NOTE
If you have trouble getting satisfactory airflow lift
values, contact 1.877.TROXLER (1.877.876.9537).
