ADVANCE PLANNING

Ductwork Planning

• Determine the exact location of the vent hood.
• Plan the route for venting exhaust to the outdoors.
• Use the shortest and straightest duct route possible. For satisfactory performance, duct run should not exceed 100 feet equivalent length for any duct configurations.
• Refer to “Duct Fittings” chart to compute the maximum permissible length for duct runs to the outdoors. See page 6.
• Use metal ductwork.
• For 48" models use: 3-1/4" x 24" or 10" round.
• For 36" and 30" models: 7" to 10" round or 3-1/4" x 12" to 3-1/4" x 24".
• Install a wall or roof cap with damper at the exterior opening.

Determine the size of the wall or roof cap for your model and installation.

- Order the caps and any transitions needed in advance. See “Duct and Duct Fittings” listed in your local yellow pages. Be sure to include equivalent lengths of caps and transitions when calculating the total duct run. See “Duct Fittings”, page 6.

48" Wide Model Duct Transitions

- Transition duct pieces are available for 48" wide models. See illustrations, ZX48BY and ZX48AY transition pieces, page 3.

Installation Framing for Adequate Support

These vent hoods are heavy. Adequate structural support must be provided. Hoods must be secured to vertical studs in the wall.

• Additional studs may be required.

- We strongly recommend that the vent hood and duct cover be on site before final framing and wall finishing. This will also help to accurately locate the ductwork and electrical service.

Decorative Duct Covers

Decorative duct covers are available for all models. The duct covers conceal the ductwork running from the top of the hood to an 8 ft. ceiling or soffit. Duct covers are available in 6" or 12" heights. See page 8 to determine need and size. See page 3 to order exact part number.

- To avoid unsightly gaps above the hood, plan the installation height carefully.

POWER SUPPLY

IMPORTANT - (Please read carefully)

③DETERMINE DUCT COVER ACCESSORIES, DUCTWORK AND WIRING LOCATIONS

We recommend that the vent hood and decorative duct cover (if used) be on site before final framing and wall finishing. This will help to accurately locate studs, ductwork and electrical service. Read these instructions to determine the need for duct cover accessories, duct fittings and wiring locations.

Duct Cover Accessories:

Perform this step to determine the need and size of an accessory duct cover. These measurements assume a typical 8ft. ceiling height.

• Measure down from the ceiling 24-1/4". Measure again to 30-1/4". Use a level to draw a horizontal line at both locations.
• 24-1/4" is the total of a 6" duct cover, 18" hood height, plus 1/4" for clearance.
• 30-1/4" is the total of a 12" duct cover, 18" hood height, plus 1/4" for clearance.

- Check the distance from the floor to the horizontal lines. The horizontal lines must fall between 66" and 72" from the floor.

- Determine the exact installation location. Use the level to draw the centerline up to the ceiling.

- Choose the location height and tape template onto the wall. Be sure the template is straight and level.

For Ceiling Heights greater than 8 ft.

Add 36" floor to cooktop height, distance from cooking surface to bottom of hood (36" max.) and hood height (18") to determine use of duct covers.

Installation below a soffit:

Ductwork can be concealed behind the soffit. Duct covers will not needed.

Determine Ductwork Locations:

CEILING DUCTING:

If ductwork will vent straight up to the ceiling:

- Use the level to draw the centerline straight up to the ceiling.

30" and 36" models:

- For 7" round, measure, 4-3/8" from the back wall to the centerline of a 7-1/2" hole on the ceiling.

48" wide models:

- For 10" round duct (using ZX48AY duct transition), measure 6-5/8" from the back wall to the centerline of a 10-1/2" hole.

IMPORTANT: Any transition used must be measured and calculated to determine exact centerline.

Centerline To Wall FOR CEILING VENT DUCTING House Wiring Duct Hole Centerline 7" or 12" Min. Above Top of Hood FOR WALL VENT DUCT 24-1/4" or 30-1/4"

WALL DUCTING:

If ductwork will vent to the rear:

- Use the level to draw a line straight up from the centerline on the template.

30" and 36" models:

- Measure 7" above the top of the hood shown on the template to the centerline of a 7-1/2" dia. duct hole. (Hole may need to be elongated for duct elbow.)

48" wide models:

- Measure at least 6-5/8" above the top of the hood shown on the template to the centerline of a 10-1/2" dia. hole duct.

House Wiring Location:

• The junction box is located on the top right side of all hood models.
• Route house wiring as close to the installation location as possible; through the ceiling, soffit or back wall.

Remove the template:

- Remove the template and set aside before going to step 4. In the next step you must locate studs or provide additional support for mounting the hood.

4 Recommended Mounting Method PROVIDE WALL FRAMING FOR HOOD SUPPORT

IMPORTANT: Framing must be capable of supporting 130 lbs.

• Mark the exact location of the vent hood as determined in step 3.
• Provide mounting support as shown below using METHOD 1 or METHOD 2.

ALTERNATE MOUNTING TIP:

Hanger screws (not supplied) can be used in the top mounting hole locations. Hanger screws will provide support to the hood while nuts and remaining lag screws are being installed.

• Install and mount the hood onto the screws. Loosely, install washers and nuts to hold the hood in place. Check level and be sure the bottom of the hood is on the horizontal line.
• Secure the hood with the supplied lag screws in remaining 4 holes. Tighten all screws and nuts.

NOTE: For 48" Wide Models

During shipping the motor may become loose and need to be tightened.

- The motor hangs by a bracket which slips into an opening in the top of the hood. Gently, push the motor up and forward. If you feel movement, use a 1/2" flat blade screwdriver to tighten the barrel nut and secure the motor.

Hanger Screw self-taps (after drilling) into wood. Protruding end has machine thread to accept nut. Also called a table screw.

Note: Double nut the screw to drive into wall stud, then remove both nuts before mounting hood.
