Before you start...

Proper installation is your responsibility. Make sure you have everything necessary for correct installation. It is the responsibility of the installer to comply with the installation clearances specified on the model/serial rating plate. The model/serial rating plate is located on the front of the downdraft vent above the wiring box cover.

Check location where downdraft vent will be installed. The location should be away from strong draft areas, such as windows, doors and strong heating vents or fans. Before making countertop cutout, check that downdraft vent and cooktop location will clear cabinet walls, backsplash, and rear wall studs inside cabinet.

IMPORTANT: Observe all governing codes and ordinances.

Failure to meet codes and ordinances could lead to fire or electrical shock.

Tools needed for installation:

Mobile home installation

The installation of this downdraft vent system must conform to the Manufactured Home Construction Safety Standards, Title 24 CFR, Part 328 (formerly the Federal Standard for Mobile Home Construction and Safety, Title 24, HUD, Part 280) or when such standard is not applicable, the Standard for Manufactured Home Installation 1982 (Manufactured Home Sites, Communities and Setups) ANSI A225.1/NFPA 501A*, or latest edition, or with local codes.

All openings in the wall or floor where retractable downdraft vent is to be installed must be sealed.

Electrical ground is required. See “Electrical requirements,” page 3.

When installing downdraft vent, the cabinet drawer will need to be removed and the drawer front installed permanently to cabinet.

NOTE: Downdraft vent is installed directly behind the cooktop. Install downdraft vent first.

Cabinet construction: Downdraft vent is designed for use in a cabinet with a depth of 24" (61 cm). Some installations require a countertop deeper than 25" (63.5 cm). See chart on page 5. The maximum depth of the overhead cabinet is 13" (33 cm). Overhead cabinets installed at either side of the downdraft vent must be 18" (45.7 cm) above the cooking surface.

See cooktop Installation Instructions before making any cutouts and for the minimum distance between the front edge of the countertop and front edge of cooktop. The minimum horizontal distance between the overhead cabinets is the same as the width of the installed downdraft vent.

When installing a 36" (91.4 cm) retractable downdraft vent with “Create-A-Cooktop” modules, the optional support must be installed on the front of the downdraft vent. See installation steps for details.

Vent system requirements

Venting system must terminate to the outside.

Do not terminate the vent system in an attic or other enclosed area.

Do not use 4" (10.2 cm) laundrytype wall caps

Do not use plastic or metal foil vent.

Vent work needed for installation is not supplied.

Wall cap is not provided with interior-mounted motor.

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

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

The size of the vent should be uniform.

Do not install two elbows together.

Use duct tape to seal all joints in the vent system.

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

Do not cut joist or stud. If vent cutout falls over a joist or stud, a supporting frame must be constructed.

Flexible metal vent is not recommended. If it is used, calculate each foot of flexible vent as two feet of rigid metal vent. Flexible elbows count twice as much as standard elbows.

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

Recommended vent system length: For either interior-mounted or exterior-mounted blower installations, vent system length should not exceed the maximum lengths listed in the “Maximum length of vent system” chart. (See this page for Interior-mounted vent motor; page 9 for exteriormounted vent motor.)

Maximum length of vent 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" (61 cm) of straight vent between any two elbows. Do not install two elbows together. It is recommended that you use round vent instead of rectangular vent, especially if elbows are required. If rectangular vent is required, it should be transitioned to 6" (15.2 cm) round vent as soon as possible.

Determining the length of system you need:

To calculate the length of system you need, add the equivalent feet for each vent piece that will be needed. See example for 6" (15.2 cm) round vent 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 (61 cm) of straight vent between any two elbows. Do not install two elbows together.

It is recommended that you use round vent instead of rectangular vent, especially if elbows are required. If rectangular vent is required, it should be transitioned to 10" (25.4 cm) round vent as soon as possible.

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 10" (25.4 cm) round vent system.

NOTE:The exterior-mounted vent motor requires a separate wiring cable that should be installed at the same time the vent work is installed.
