Installation
STEP 5
Venting Installation Guidelines
• The following steps are for exterior ventilation.
Height and Clearance
IMPORTANT:
• Vent system must terminate to the outside (roof or side wall).
• DONOT terminate the vent system in an attic or other
enclosed area.
• DONOTuse4”(10.2cm)laundry-typewallcaps.
• Usemetal/aluminumventonly.Arigidmetal/aluminum
vent is recommended.
• DONOTuseaplasticvent.
• Alwayskeeptheductcleantoensureproperairflow.
• Calculatethefollowingfiguresbeforeinstallation:
1. Distance from the floor to the ceiling
2. Distance between the floor and the countertop/stove
3. A distance of 24” to 30” is recommended between
stove top and the bottom of range hood. 30” minimum
is required for gas stove tops.
4.
Height of duct aperture and duct cover.
For the most efficient & quiet operation:
• Itisrecommendedthattherangehoodbevented
vertically through the roof through 10” (15.3 cm) or
bigger round metal/aluminum vent work.
• Thesizeoftheventshouldbeuniform.
• Usenomorethanthree90°elbows.
• Make sure there is a minimum of 24” (61 cm) of
straight vent between the elbows if more than one
elbow is used.
• DONOTinstalltwoelbowstogether.
• The length of vent system and number of elbows should be
kept to a minimum to provide efficient performance.
• Theventsystemmusthaveadamper.Ifrooforwall
cap has a damper, you may remove damper flaps from
damper to increase air flow.
•
Only one flange is needed in the air duct system,
either on top of the motor (provided) or outside.
•
Use silver tape or duct tape to seal all joints in
the vent system.
24” (610 mm) Min / 30” (762 mm) Max
To reach 9 ft ceiling, make sure
range hood is installed at least
30” (762 mm) from cooking surface.
• Use caulking to seal exterior wall or roof opening
around the cap.

28” (711 mm)
Wall duct aperture is 28” (711 mm)
from bottom of range hood
