KitchenAid 36" Commercial-Style Hood Installation Guide

Minimum distance “X”: 30" (76.2 cm)
Suggested maximum distance “X”: 36" (91.4 cm)

■

Vent system must terminate to the outdoors.

■

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 vent only. Rigid metal vent is recommended. 
Plastic or metal foil vent is not recommended.

■

The length of vent system and number of elbows should be 
kept to a minimum to provide efficient performance.

■

Use no more than three 90° elbows.

■

Make sure there is a minimum of 24" (61.0 cm) of straight 
vent between the elbows if more than 1 elbow is used.

■

Do not install 2 elbows together.

■

Use clamps to seal all joints in the vent system.

■

The vent system must have a damper. If the roof or wall cap 
has a damper, do not use the damper supplied with the range 
hood.

■

Use caulking to seal exterior wall or roof opening around the 
cap.

■

The size of the vent should be uniform.

An additional back draft damper should be installed to minimize 
backward cold air flow and a thermal break should be installed to 
minimize conduction of outside temperatures as part of the vent 
system. The damper should be on the cold air side of the thermal 
break.

The break should be as close as possible to where the vent 
system enters the heated portion of the house.

Local building codes may require the use of make up air systems 
when using ventilation systems greater than specified CFM of air 
movement. The specified CFM varies from locale to locale. 
Consult your HVAC professional for specific requirements in your 
area.

A 6" (15.2 cm) round vent system is needed for installation (not 
included). The hood exhaust opening is 6" (15.2 cm) round. Two 
6" (15.2 cm) round vent systems are needed for installation on 
48" (121.9 cm) models.

NOTE: Flexible vent is not recommended. Flexible vent creates 
back pressure and air turbulence that greatly reduce 
performance.

Vent system can terminate either through the roof or wall. The 
exhaust collar can also be directed to vent out the rear of the 
hood.

To vent through the wall, the blower needs to be changed to the 
proper orientation.

*The 48" (121.9 cm) hood uses two 6" (15.2 cm) round vents or 

transitions to 10" (25.4 cm) round vent using Part Number 
4396915.
