Venting Requirements
IMPORTANT: This cooktop must be exhausted outdoors unless using the Duct- Free Filter Accessory Kit. See the “Venting Methods” section.

• Do not terminate the vent system in an attic, wall, ceiling, or concealed space of a building.
• Use a vent cap.
• The vent system must terminate to the outside.
• Use only a 6″ (15.2 cm) diameter round or 3 1/4″ x 10″(8.3 cm x 25.4 cm) rectangular vent except as follows: For electric cooktops, a 5″ (12.7 cm) diameter round vent may be used for venting straight out the back of the cooktop and directly through the wall for 10 ft (3.0 m) or less.
• Before making cutouts, make sure there is proper clearance within the wall or floor for the exhaust vent.
• Do not cut a joist or stud unless absolutely necessary. If a joist or stud must be cut, then a supporting frame must be constructed.
• The size of the vent should be uniform.
• The vent system must have a damper.
• Use vent clamps to seal all joints in the vent system.
• Use caulking to seal the exterior wall or roof opening around the cap.
• Determine which venting method is best for your application.

For Best Performance:

• Use a 26-gauge minimum galvanized or 25-gauge minimum aluminum metal vent. Poor-quality pipe fittings can reduce airflow. The flexible metal vent is not recommended.
  NOTE: Local codes may require a heavier gauge material.

• The metal duct may be reduced to 30-gauge galvanized steel or 26-gauge aluminized steel if allowed by local codes.
  This reduction is based on information in the International Residential Codes Section M1601.1 (2006 edition).

• Do not install 2 elbows together.

• Use no more than three 90° elbows.

• If an elbow is used, install it as far away as possible from the vent motor exhaust opening.

• Make sure there is a minimum of 18″ (45.7 cm) of straight vent between the elbows if more than one elbow is used.

• Elbows too close together can cause excess turbulence that reduces airflow.

• Do not use a 5″ (12.7 cm) elbow in a 6″ (15.2 cm) or 3 1/4″ x 10″ (8.3 cm x 25.4 cm) system.

• Do not reduce to a 5″ (12.7 cm) system after using 6″ (15.2 cm) or 3 1/4″ x 10″ (8.3 cm x 25.4 cm) fittings.

• Avoid forming handmade crimps. Handmade crimps may restrict airflow.

• Use a vent cap for proper performance. If an alternate wall or roof cap is used, be certain the cap size is not reduced and that it has a backdraft damper.

• Use vent clamps to seal all joints in the vent system.

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

The length of the vent system and the number of elbows should be kept to a minimum to provide efficient performance.
The maximum equivalent length of the vent system is 60 ft (18.3 m). For altitudes above 4,500 ft (1372 m), reduce recommended vent run by 20% for best performance.
Cold Weather Installations
An additional backdraft damper should be installed to minimize backward cold airflow.
Makeup Air
Local building codes may require the use of makeup air systems when using ventilation systems greater than the specified CFM of air movement. The specified CFM varies from locale to locale. Consult your HVAC professional for specific requirements in your area.

Duct-Free Filter Accessory Kit
The Duct-Free Filter Accessory Kit Part Number W10620783 is now available. Duct-Free Filter Accessory Kit is ideal for both new construction and kitchen renovation projects because it provides an easy alternative to the installation of metal ducting and venting in the downdraft system outside the home. The kit includes all required hardware, one filter, and complete installation instructions. Replacement Filter Part Number W10177003 is available.

Calculating Vent System Length
To calculate the length of the system you need, add the equivalent feet (meters) for each vent piece used in the system.

(1.5 m)
6″ (15.2 cm) to 3 1/4″ x 10″ (8.3 cm x 25.4 cm) 90° elbow transition| 5.0 ft (1.5 m)
3 1/4″ x 10″ (8.3 cm x 25.4 cm) 90° elbow| 5.0 ft (1.5 m)
3 1/4″ x 10″ (8.3 cm x 25.4 cm) flat elbow| 12.0 ft (3.7 m)
3 1/4″ x 10″ (8.3 cm x 25.4 cm) wall cap| 0.0 ft (0.0 m)

Example vent system

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

Before You Make the Electrical Connection:
To properly install your cooktop, you must determine the type of electrical connection you will be using and follow the instructions provided for it here.

• A 4-wire or 3-wire, single-phase, 120/240 V, 60 Hz, AC-only electrical supply on a separate, 40 A circuit breaker is required for both 30″ (76.2 cm) and 36″ (91.4 cm) models. If a fused system is used, fuse both sides of the line.
• The cooktop should be connected directly to the junction box through the flexible metal conduit. The flexible, armored cable extending from the fuse box or circuit breaker box should be connected directly to the junction box.
• Locate the junction box to allow as much slack as possible between the junction box and the cooktop so that the cooktop can be moved if servicing becomes necessary in the future.
• A UL-listed or CSA-approved conduit connector must be provided at each end of the power supply cable (at the cooktop and at the junction box).
• If the house has aluminum wiring, follow the procedure below:
• Connect the aluminum wiring using special connectors and/or tools designed and UL-listed for joining copper to aluminum.

Follow the electrical connector manufacturer’s recommended procedure. Aluminum/copper connection must conform with local codes and industry-accepted wiring practices.
