Venting Installation Guidelines
• The following steps are for exterior ventilation.
• If you require a ductless installation, please visit anconahome.com to purchase a recirculation kit.
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 hood 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 aire duct system,
either on top of the motor or outside.
• Use silver tape or duct tape to seal all joints in the
vent system.
• Use caulking to seal exterior wall or roof opening
around the cap.
