Step 3: Prepare Duct Cutouts in
Cabinet
Y A. Refer to Figure 8. Drop a plumb-line
from Point "P" at the rear center of the
countertop cutout. Mark this point on
the bottom of the cabinet below. Con-
struct two reference lines through this
point: one should be parallel to the cabi-
net front and directly below the rear
countertop cutout (Line A-A), and the
other (Line
B-B) should be at right angles to A-A.
Y B. Using these reference lines as a base
for the measurements, layout the neces-
sary cabinet cutouts needed to imple-
ment the planned ductwork route.
Where a range of measurements is
noted, choose a measurement that al-
lows best clearance from wall studs,
floor joists, utilities, or other obstructions.
Y C. Before cutting for ducting, temporarily
set intake and cooktop in place and at-
tach integral blower (or duct transition fit-
ting if a remote or inline blower is
installed). Refer to steps 6 and 7. Verify
that the duct cutouts as marked will
match the hardware installation. Adjust
the duct cutout as necessary to match
hardware installation.
Y D. Remove temporarily placed hardware
and make cutouts in cabinet to accom-
modate ductwork installation.
Y E. Make all other cabinet modifications
needed to provide proper clearances for
drawers or removable shelving.
Note: Check boxes as tasks are completed.

ting if a remote or inline blower is

Note: Check boxes as tasks are completed.
Step 4: Install Ductwork (Remote or
Inline Blower, If Used)
Y A. Install the ductwork and remote blo-
wer (if used) in accordance with the
ductwork routing plan developed in Step
1.
Y B. Make sure that the installation com-
plies with all installations guidelines. Type
and length of ducting and lack of make-
up air may reduce CFM. Also check that
the opening where duct passes through
outside wall or roof has been properly
flashed and sealed to prevent leakage.
Y C. If using Integral Blower, proceed to
Step 5.
Y D. If using Remote or Inline Blower, refer
to Installation Instructions with that
model.
Step 5: Install Electrical Service
Y Check your local building codes for pro-
per method of installation. In the U.S., if
there are no applicable local codes, this
unit should be installed in accordance
with the National Electric Code
ANSI/NFPA No. 70, Current Issue. (In
Canada, installation must be in accor-
dance with the CAN 1-B149.1 and .2-In-
stallation Codes for Gas Burning
Appliances and/or local codes).
Y The appliance must be grounded. In the
event of an electrical short circuit, groun-
ding reduces the risk of electric shock by
providing an escape wire for the electric
current. This appliance is equipped with
a cord having a grounding wire with a
grounding plug. The plug must be plug-
ged into an outlet that is properly instal-
led and grounded.
WARNING – Improper grounding can
result in a risk of electric shock.
Only a qualified electrician, or similarly quali-
fied persons, should make the electrical
connections.
Do not use an extension cord. If the power
supply cord is too short, have a qualified
electrician install an outlet near the applian-
Fig. 8
ce.
The receptacle should be located under
the countertop so that the 30 inch long
power cord from the vent will reach it.
See Figure 8.
Y The cord should be routed beneath the
appliance and away from heat generated
by the cooktop. Access should not be
obstructed by blower, cabinet work,
ductwork or electrical/gas utilities for the
cooktop. All power for the vent system
(including the remote blower, if used) is
supplied via the cord to the intake unit.
The outlet can usually be extended from
another kitchen outlet or have its own
circuit from the main service panel.
Do not plug vent cord into receptacle
until Step 8.
Step 6: Mount Vent and Cooktop
Y A. Remove grease filters and any pak-
king materials from inside the intake.
Y B. Set the vent intake into rear of coun-
tertop opening. Carefully lower it into po-
sition so that the flanges on the rear
sides and edges fully support the unit
hanging from the countertop.
Y C. Hold the unit against the rear of the
countertop opening, and slide the leg
brackets down to meet the bottom of
cabinet. Check and adjust for plumb,
then fasten leg brackets to cabinet with
hardware provided.
Note: Check boxes as tasks are completed.
