1. Do not install the range hood near open doors and windows to avoid reduced
performance. (Fig.1)
2. Install the range hood directly above the cooktop. The optimal distance between the
cooktop and lower edge of the range hood is 24" to 36". (Fig.2) Install at the height
appropriate to your ceiling. Make sure the chimney reaches the ceiling. If your ceiling
leaves the hood a few inches higher or lower than 24" to 36" you can still install it without a
major loss of performance.
3. For optimal performance, do not over extend the exhaust tube and avoid unnecessary
bending. (Fig.3)
4. After hanging the unit on the wall, ensure the range hood is straight and leveled. (Fig.4)
5. The air outlet must be connected to chimney flumes or combustion gas ducts. Under no
circumstances should the air outlet be connected to ventilation ducts for rooms in which
fuel-burning appliances are installed.
