Fire Hazard

Venting system MUST terminate to the outside.

Do Not terminate the ductwork in an attic or other enclosed space.

Do Not use 4-inch laundry-type wall caps. Do Not use plastic-type ductwork.

Use Only Metal Ductwork.

Failure to follow these instructions may result in a fire.

Ductwork needed for installation is not supplied.

Wall cap is Not provided with interior- mounted motor.

Determine which venting method to use. Ductwork can extend either through the wall or roof.

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

II Put on gloves and safety glasses.

. Place cardboard or another form of protection on top of a flat surface where you can easily assemble the downdraft vent system. Remove parts packages, downdraft vent and blower box from carton. Remove all shipping materials, tape and protective film from downdraft vent and blower box.

l The size of the ductwork should be uniform.

l Do Not install two elbows together.

l Use duct tape to seal all joints in the ductwork system.

l Use caulking tape to seal the exterior wall or floor opening around cap.

l Do Not cut joist or stud. If ductwork cutout falls over a joist or stud, a supporting frame must be constructed.

. Flexible metal ductwork is Not

recommended. If it is used, calculate each foot of flexible ductwork as two feet

Do not vent a gas cooktop into a window well.

of rigid metal ductwork. Flexible elbows count twice as much as standard elbows.

NOTE: Make sure there is proper clearance within the wall or floor exhaust duct before making cutouts.

Recommended duct length

For either interior-mounted or exterior- mounted blower installations, ductwork length should not exceed the maximum lengths listed in the “Maximum length of duct system” chart. (See Panel C for interior-mounted blower; Panel E for exterior-mounted blower.)

Interior-mounted vent motor

Seal the s ace between the outside of wall cap inlet inside of BVC coupling with caulking metal.

Maximum length of ductwork system

For best performance, use no more than three 90” elbows. If more than one elbow is used, make sure that there is a minimum of 24 inches of straight duct between any two elbows. Do Not install two elbows together. It is recommended that you use round duct instead of rectangular duct, especially if elbows are required. If rectangular duct is required, it should be transitioned to 6” round duct as soon as possible.

Attach support legs to side of downdraft vent with two screws in

each leg. Do Not tighten screws.

Injury Hazard

Use two or more people to move and install downdraft vent.

Failure to follow this instruction can result in back or other injury.

Determining the length of system you need:

To calculate the length of system you need, add the equivalent feet for each duct piece that will be needed. See example for 6” round ductwork system.

Maximum length = 25 ft.

1 - wall cap		=	0	feet
8 feet	straight	=	8	feet
2 - 90”	elbows	=	10	feet

Length of 6” system = 22.5 feet

14. Carefully insert downdraft vent into countertop cutout. Two people are

recommended to support the weight of the downdraft vent during lifting. Check that downdraft vent is parallel to side of cutout and that mounting brackets overlap countertop.

15)Move support legs down against

’ cabinet floor. Place a level against front of downdraft vent base and adjust until downdraft vent is level vertically. Use a pencil to mark the top of each leg on face of downdraft vent. Then mark location of support leg mounting holes on cabinet floor. Remove downdraft vent from cutout. Drill starter holes at each mounting screw location on cabinet floor. Align top of legs with pencil marks on face of downdraft vent. Tighten screws in legs.
