Preparing the Hood, Planning Ductwork Installation

PREPARING THE HOOD

1.Unpack hood and check contents. You should receive: 1 – Filter with built-in light lens

1 – 3-1/4" x 10" damper/duct connector

1 – Installation parts bag

LIGHT LENS

ALUMINUM OR

COMBINATION

FILTER

2. Remove junction box cover.	JUNCTION BOX

3.Remove top or rear electrical knockout.

4.Select one of the three types of venting available: Non-Vented— Remove vent cover from hood front. Replace the aluminum filter with a non-ducted filter (BP57 or R610050 - purchase separately). Go to "Preparing the Installation Loca- tion".

VENT COVER

Rectangular Vented — 3-1/4" x 10" vertical or horizontal. Re- move knockout #② for vertical or knockout #③ for horizontal venting. Install damper/duct connector over opening. Go to "Planning Ductwork Installation".

Ducting directly through the wall (for range hoods mounted on an exterior wall). Shown are two ways to duct through an outside wall. If a wall cap is used directly off the back of the hood, special care must be taken to make sure that the damper in the damper/duct connector on the hood and damper in the wall cap do not interfere with each other when the hood is operating. This could result in either inadequate air delivery or back drafts. If this condition does exist, remove the hood damper flap. Sometimes when using a wall cap, it is easier to duct vertically and then use an elbow.

Ducting straight up through roof using 3-1/4" x 10" or 7" round duct. For single story installations.

Ducting between ceiling joists for multi-story installations or through soffits above cabinets where soffit connects to outside walls.

PREPARING THE INSTALLATION LOCATION

NOTE: MOUNT HOOD SO THAT BOTTOM OF HOOD IS 18" TO 25" ABOVE COOKING SURFACE. TOP FRONT OF HOOD SHOULD BE FLUSH WITH FRONT OF CABINET FRAME.

IF DISTANCE BETWEEN WALL AND FRONT OF CABINET FRAME IS MORE THAN 12", THERE WILL BE A SPACE BE- TWEEN BACK OF HOOD AND WALL. THIS IS NORMAL.

OMIT STEP 1 IF HOOD WILL BE INSTALLED UNDER CABI- NETS WITH FLUSH BOTTOM.

Round Vented — 7" vertical. Remove knockouts #① and #② exposing duct collar. Go to "Planning Ductwork Installation".

PLANNING DUCTWORK

INSTALLATION

This section for vented hoods only. Non-vented hoods skip this section and go on to "Preparing the Installation Loca- tion".

Begin planning ductwork by deciding where duct will run between
hood and outside. For best performance, use shortest possible
duct run and a minimum number of elbows. There are several
choices.	2

FILLER STRIP

1.For cabinets with recessed bottoms only: Install wood filler strips on each side of recessed area under cabinet. Use two 1" x 2" strips cut to length (use thicker strips if necessary). Fasten strips with wood screws about 3" in from each end.

2.Measure and mark the following:

a.) Electrical wiring opening in wall or cabinet.

b.) Duct opening in wall or cabinet (vented hoods only).
