cold air side of the thermal
break. The break should be as
close as possible to where the
ducting enters the heated
portion of the house.
4. Hood installation height above
cooktop is the users preference.
The closer the hood is to the
cooktop the more efficient it will
be in capturing of cooking odors,
grease and smoke. Thermador
recommends the hood be in-
stalled 30-36" above the
countertop. The lower height
may be inconvenient for tall
people and large cooking vessels.
Check your ceiling height and
the hood height maximum before
you select your hood.
1. For the most efficient air
flow exhaust, use a straight
run or as few elbows as
possible.
CAUTION: Vent unit to
outside of building, only.
2. Use flex ducting only to
connect rigid duct directly to
transitions.
3. COLD WEATHER installa-
tions should have an addi-
tional backdraft damper
installed to minimize
backward cold air flow and a
nonmetallic thermal break
to minimize conduction of
outside temperatures as
part of the ductwork. The
damper should be on the

Preparation of mounting
surface (Drywall)
1. Select a mounting height
comfortable for the user and
mark on wall behind cooking
surface.
2. Mark centerline of cooking
surface and draw vertical line
from bottom of hood to the
ceiling.
3. Tape template, matching
center-line and hood bottom as
shown in Fig. A.
4. Mark centers of the 6 fastener
locations through template on
wall then remove template.
5. Mark wall with horizontal line
1" above highest and 1" below
lowest fastener location.
6. Find studs behind drywall by
tapping wall or using a stud
finder. Mark the center of the
studs with a vertical
line to the right and
left of the marked
fastener location.
Note: 2 x 6's must
span at least 2 studs
side to side.
7. Cutout drywall along
marked lines. Install
2 x 6's between studs
firmly flush with stud
front. Make sure all
mounting screws will
anchor to added
lumber. Replace
drywall and refinish.
8. Attach template to
wall using cooking
surface centerline
and hood installation
height as shown in
Fig. A

4. Secure hood with 2 screws on
top and 2 screws on bottom.
See Fig. D.
5. REMOTE VENTILATOR AND
DUCT INSTALLATION. Refer to
instructions shipped with
remote ventilator model
VTR1000Q or VTR1400Q for
installation of remote blower
and ducting. The remote
ventilator inlet fits 10" round
duct. Transition to 8" round
prior to passing through ceiling
or wall for duct cover clearance
and connecting to the hood
transition. Do not use ducting
smaller than 8" round.
6. Connect ducting to transition
using starter collar provided
with hood (See Fig. C). Locate
collar screws so they fit into
corner of the duct cover.
Secure collar to transition and
duct with three sheet metal
screws each. Seal with duct
tape.
7. Install wiring for
remote ventilator and
power supply. See
electrical installation on
page 7.
8. Install duct covers
on top of hood as shown
in Fig. B. Raise inside
cover and attach to duct
cover bracket using two
sheet metal screws
provided.
Appliance Installation:
1. Install transition on top of hood
if removed for shipping. Fig. C
2. Hang hood on 2 mounting
hooks through the rectangular
cutouts on back of hood. Fig. D
3. Level the appliance shown in
Fig. D.

Alternate Installations
Reduced Ceiling Height
Installation for HNW model:
The hood may be installed with
only the lower part of the duct
cover to reduce the overall
height. This hood height is
signified by *in Table 1.
1. For the duct cover to slide
down and engage the top of
the hood position the duct
cover bracket 1" below the
ceiling.
2. Fill in the gap between the
ceiling and top of the
chimney with a 1" thick
piece of wood cut to the inside
cross section of the chimney
cover.
3. Finish the wood to match the
ceiling.
4. Copy the two mounting holes
on the sides of the upper
cover to the lower cover.
5. Install lower cover on hood
and secure to mounting
bracket with two sheet metal
screws.
Rear discharge
For rear discharge a 90 degree
elbow may be installed immedi-
ately above the hood. The
distance from the bottom of the
hood to top of the transition is
provided by dimension "T" in
Table 1.

ELECTRICAL
INSTALLATION
Warning: Switch power off at
service panel and lock the
service disconnecting means
before wiring this unit.
Wiring Remote Ventilator
VTR1000Q or VTR1400Q:
1. Run five wires #14 AWG
(black, white, blue, red,
and green) in 1/2” conduit
from the remote ventilator
to the hood.
2. Install conduit connector
at the end of the conduit.
Remove the knockout on
top of the junction box.
Attach conduit connector

3. Use the four wire bundle
and ground wire in the
junction box for
connecting to the remote
ventilator wires. Connect
black wire from the
remote ventilator to the
black wire in the junction
box, red to red, blue to
blue, white to white, and
green to green. Do not
connect to the power
supply wire bundle
containing a black and
white wire. See Figure E.
Wiring To Power Supply:
1. Installation requires a
15A circuit. Run three
wires: black, white, and
green using #14 AWG from
the service panel to the
junction box.
2. Remove junction box cover
HNW
as shown in Figure E.
3. Remove the knockout and
install 1/2” conduit
connector.
4. Connect black wire from
service panel to black in
junction box, white to
