Before you start...

Your safety and the safety of others are very important.

We have provided many important safety messages in this manual and on your appliance. Always read and obey all safety messages.

This is the safety alert symbol.

This symbol alerts you to potential hazards that can kill or hurt you and others.

All safety messages will follow the safety alert symbol and either the word “DANGER” or “WARNING”.

These words mean:

DANGER

You can be killed or seriously injured if you don’t immediately follow instructions.

WARNING

You can be killed or seriously injured if you don’t follow instructions.

All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury, and tell you what can happen if the instructions are not followed.

IMPORTANT: Observe all governing codes and ordinances.

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

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.

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.

Electrical requirements

IMPORTANT: Observe all governing codes and ordinances.

It is the customer’s responsibility:

•To contact a qualified electrical installer.

•To assure that the electrical installation is adequate and in conformance with National Electrical Code, ANSI/NFPA 70

— latest edition*, or CSA Standards C22.1-94, Canadian Electrical Code, Part 1 and C22.2 No. 0-M91 - latest edition** and all local codes and ordinances.

If codes permit and a separate ground wire is used, it is recommended that a qualified electrician determine that the ground path is adequate.

Do not ground to a gas pipe.

Check with a qualified electrician if you are not sure downdraft vent is properly grounded.

Do not have a fuse in the neutral or ground circuit.

IMPORTANT: Save Installation instructions for electrical inspector’s use.

A. A 120-volt, 60-Hz, AC-only, fused electrical supply is required on a separate 15 amp circuit. A time-delay fuse or circuit breaker is recommended. The fuse must be sized per local codes in accordance with the electrical rating of the downdraft vent as specified on the model/serial rating plate located on the front of the downdraft vent above the wiring box cover.

B. The downdraft vent must be connected with copper wire only.

C. Wire sizes and connections must conform to the requirements of the National Electrical Code, ANSI/NFPA 70 — latest edition*, or CSA Standards C22.1-94, Canadian Electrical Code, Part 1 and C22.2 No. 0-M91 - latest edition** and all local codes and ordinances.

WARNING — TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:

Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable Codes and Standards, including fire related construction. Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent back drafting. Follow the heating equipment manufacturer’s guideline and safety standards such as those published by the National Fire Protection Association (NFPA),and the American Society of Heating Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.

When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.

Ducted fans must always be vented to the outdoors.

WARNING — To reduce the risk of fire, use only metal ductwork.

This unit must be grounded.

D. This downdraft vent should be connected directly to the fused disconnect (or circuit breaker) through flexible, armored or nonmetallic sheathed, copper cable. Allow some slack in the cable so the downdraft vent can be moved if servicing is ever necessary.

E. A U.L.- or C.S.A.-listed, 1/2" (12.7 mm) conduit connector must be provided at each end of the power supply cable (at the downdraft vent and at the junction box).

F. A wiring diagram is located on the downdraft vent base above the wiring box cover.

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.)

3-1/4" x 10"	35 feet (8.9 m)
(8.3 cm x 25.4 cm)

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"
