4. Install Transition
For internal blower installation, install the 7"
transition (included) to connect to 7" ducting. If 7"
ducting is not available, 8" ducting may be used. In
this instance, an additional 7-8" transition must also be
used (not included).
For remote blower applications, 10" ducting is
required. In this instance, a 7"-10" transition must
also be used.
Attach the transition with 4 #8 sheetmetal screws
(included) and seal connection with duct tape.
For best results, install transition so that damper hinge
runs front to back (not side to side).
5. Mount the Hood
The DAH model hood can be mounted through the
back wall or through the top. See General Information,
page 3, for suggestions for hood height.
Once the preferred height is determined, locate the
centerline (left to right) of the cooking appliance.
Wall Mount
1. From the centerpoint of the cooking appliance,
measure up to the preferred height. Measure up an
additional 9" to locate the centerline of the screw
holes (see Figure 4).
2. Install wood screws through wall leaving 1/4" of
the screws exposed.
Install one wood screw 11 1/2" to the left of the
centerline and one wood screw 11 1/2" to the right
of the centerline. These are the only installation
points for the 30" hood. See Figure 4.
For the 36" hood, there are 2 additional installation
points. These are also at the centerline height, but
are 15 3/8" from the centerline in each direction.
See Figure 4.
3. Place the hood by sliding the mounting holes in the
hood over the screw head.
4. Tighten the screws.
5. Note: For drywall or hollow walls please use
appropriate wall anchors in place of wood screws.
Top Mount
1. Install the hood flush against the back wall.
2. Identify the centerline on the mounting surface
(underside of cabinet).
3. Place the hood and install the wood screws through
the mounting holes.
Insert 3 wood screws 11 1/2" off the centerline in
both directions at the following depths:
1. 2 1/4" from the back wall
2. 8 1/4" from the back wall
Installation
3. 9 1/4" from the back wall
See Figure 5.
The 36" hood also requires 3 additional screws, at
the same depths, on each side (total of 6). These
are 15 3/4" from the center line (See Figure 5).
4. Place the hood.
5. Tighten the screws.
