Venting Requirements

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

area.

■ Use a Jenn-Air

■ Vent system must terminate to the outside.

■ Use only a 6" (15.2 cm) round metal vent. Rigid metal vent is

recommended. For best performance, do not use plastic or metal foil vent.

■ 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. If roof or wall cap has a

damper, do not use damper supplied with the range hood.

vent cap.

■ Use only a 6" (15.2 cm) round metal vent or a 3¹⁄₄" x 10"

(8.3 x 25.4 cm) rectangular metal vent except for as follows:

■ For electric models, 5" (12.7 cm) diameter round metal

vent may be used for venting straight out the back of the cooktop and directly through the wall for a duct length of 10 ft (3.0 m) feet or less.

■ For gas models, 5" (12.7 cm) diameter round metal vent

must be used if the duct length is 10 ft (3.0 m) feet or less.

■ Do not use 5" (12.7 cm) elbows except in a 5" (12.7 cm)

system. Instead, use a 5" (12.7 cm) to 6" (15.2 cm) elbow or a 5" (12.7 cm) to 3¹⁄₄" x 10" (8.3 x 25.4 cm) elbow transition.

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

■ Use caulking to seal exterior wall or roof opening around the

cap.

■ Determine which venting method is best for your application.

For Best Performance:

■ Use 26-gauge minimum galvanized or 25-gauge minimum

aluminum metal vent. Poor quality pipe fittings can reduce airflow. Flexible metal vent is not recommended.

NOTE: Local codes may require a heavier gauge material.

■ 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

hood’s 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 3¹⁄₄" x 10"

(8.3 x 25.4 cm) system.

■ Do not reduce to a 5" (12.7 cm) system after using

6" (15.2 cm) or 3¹⁄₄" x 10" (8.3 x 25.4 cm) fittings.

■ Avoid forming handmade crimps. Handmade crimps may

restrict airflow.

■ Use a Jenn-Air

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 back draft damper.

The length of vent system and 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 (1272 m), reduce recommended vent run by 20% for best performance.

Cold Weather Installations

An additional back draft damper should be installed to minimize backward cold air flow and a thermal break 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.

Makeup Air

Local building codes may require the use of makeup 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.

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

Determine Range Blower Setting

This cooktop is equipped with a dual range blower. It is shipped from the factory in the low range for most installations. If the equivalent duct length exceeds 30 ft (9.1 m), it must be converted to high range. Do not convert the blower to high range for shorter lengths; this will cause excessive noise and conditioned air loss. Convert blower before installing into countertop if necessary.

WARNING

Excessive Weight Hazard Use two or more people to move and install cooktop. Failure to do so can result in back or other injury.

To Convert to High Range:

1. Using 2 or more people, place cooktop on floor with front

edge and plenum down.

2. Remove the four acorn nuts (A) that attach the blower motor

assembly to the blower exhaust scroll.

3. Remove the blower motor assembly (B) from the blower

exhaust scroll (E).

4. Slowly reach in the blower exhaust scroll opening and

remove the snap ring (C).

5. Gently remove the restrictor ring (D).

6. Place the motor assembly back on the studs of the blower

exhaust scroll.

A. Acorn nuts (4) B. Blower motor assembly C. Snap ring D. Restrictor ring

E. Blower exhaust scroll

Electrical Requirements

WARNING

Electrical Shock Hazard Disconnect power before servicing. Use 8 gauge copper wire. Electrically ground cooktop. Failure to follow these instructions can result in death,

fire, or electrical shock.

If codes permit and a separate ground wire is used, it is recommended that a qualified electrical installer determine that the ground path and wire gauge are in accordance with local codes.

Check with a qualified electrical installer if you are not sure the cooktop is properly grounded.

Make sure that the electrical connection and wire size are adequate and in conformance with the National Electrical Code, ANSI/NFPA 70-latest edition or CSA Standards C22.1-94, Canadian Electrical Code, Part 1 and C22.2 No. O-M91-latest edition, and all local codes and ordinances.

A copy of the above code standards can be obtained from: National Fire Protection Association

1 Batterymarch Park Quincy, MA 02169-7471

CSA International 8501 East Pleasant Valley Road Cleveland, OH 44131-5575

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 volt, 60 Hz., AC

only electrical supply is required on a separate, 40-amp circuit (30" [76.2 cm] models), 20-amp circuit (20" [50.8 cm] models) or 60-amp circuit (43" [109.2 cm] models), fused on both sides of the line.

■ The cooktop should be connected directly to the junction box

in the cabinet through the flexible metal conduit. The flexible, armored cable extending from the fuse box or circuit breaker box should be connected directly to the cooktop wiring box.

■ Locate the junction box in the cabinet 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 wiring box and at the junction box in the cabinet).

■ If the house has aluminum wiring follow the procedure below:

Connect a section of solid copper wire to the pigtail leads.

2. Connect the aluminum wiring to the added section of

copper wire 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.

4. Remove the removable grease filter by lifting the filter out.

5. Using 2 or more people, remove the cooktop from the carton.

6. Use foam end caps from the packaging as a work surface for

the floor or countertop.

7. Using 2 or more people, place the cooktop on the foam end

caps.

8. Avoid placing the cooktop face down on the control knobs. REMEMBER: An undercounter built-in oven cannot be

installed under this cooktop.

Rotate Blower - Optional

IMPORTANT: The following additional steps must be performed if the product is being installed in peninsula or island cabinetry.

The blower exhaust scroll is shipped from the factory set to exhaust straight out the back of the cabinet through an exterior wall.
