INTRODUCTION
GENERAL DESCRIPTION
The complete downdraft system consists of
the downdraft, a blower and a transition
box if using an Inline or Remote Blower. A
recirculation module is also available when
ducting to the outside is not preferred or
not possible. (See Fig. 1).
The blower can be either integral (mounted
on the vent intake in the cabinet under the
cooktop), an inline (mounted between the
kitchen and exterior wall anywhere within
the duct line), or a remote (mounted on the
roof or outside wall). When a remote or inli-
ne blower is used, a duct transition is
mounted on the ventilator intake in place of
the integral blower to connect the intake to
the duct work. The duct transition must be
purchased separately.
The integral blower or duct transition can
be mounted in different positions on the
intake to route ductwork to avoid cabinet,
building framing, utilities, etc.
The downdraft system is available in 30-
inch or 36- inch. Intended for non-profes-
sional style cooktops only.
A Recirculation Kit can be purchased sepa-
rately and used in conjunction with the Inte-
gral Blower if ducting to the outside is not a
viable option.
Step 1: Plan the installation
Carefully follow the planning procedures
listed below (See Figure 2). Sketches are
NOT intended to be a replacement for
careful planning.
A. Determine whether a remote, inline, or
integral blower will be used. Remote
and inline blower installation requires
4 wires plus a ground wire to run from
the downdraft to the blower.
B. Make sure that adequate cabinet and
counter space has been provided and
that the intake and blower will be acces-
sible if service is required.
C. Consider that cross drafts created by
adjacent open windows, doors, air con-
ditioning, old heating vents, recessed
ceiling lights, and traffic patterns may
affect performance.
D. For gas cooktop installations make sure
that a minimum 10 square inch opening
is provided in the toe-kick or other cabi-
net area. Inadequate ventilation of the
cabinet below the cooktop may result in
flame outage when operating the vent
system.
E. Provide for air supply or ”make-up
air” to the room where unit will be
installed. If ”make-up air” is not provi-
ded, then problems, such as fireplace
chimney downdrafts, could result.

F. Investigate potential ductwork routes
and choose the shortest possible route
from the unit to an outside wall or to the
roof via an inside wall and attic. For gui-
dance, typical ducting installations are
shown in figures 3 through 6. Installation
in island locations will require under floor
ducting. Peninsula locations usually
require ducting laterally through cabinets
or under cabinet toe spaces. Consider
potential interferences to ductwork from
building framing (floor joists, wall studs,
etc.) and utilities (electrical wiring, water,
gas, or sewer lines, etc).
G. Purchase the necessary ductwork as
needed to duct to the outside or purcha-
se separately the downdraft Recirculati-
on Module if ducting to the outside is not
a viable option.
• Be certain to avoid inter-
ference with gas and elec-
tric supply to cooktop.
• Shelving and drawer depths
are dependent upon cook-
top depth and setback.

DUCTWORK INSTALLATION GUIDE-
LINES
GDucting should vent directly outdoors
(not into an attic, underneath the house,
into the garage or into any enclosed
space). A Recirculation Module is availa-
ble when ducting to the outside is not
possible.
GKeep duct runs as short and straight as
possible.
GDuct fittings (elbows and transitions)
reduce air flow efficiency.
GBack to back elbows and ”S” turns give
very poor delivery and are not recom-
mended.
GA short straight length of duct at the inlet
of the remote blower gives the best deli-
very.
GTransition to duct from the integral blo-
wer or remote duct transition as close to
the downdraft as is possible. In order of
preference, use
1st. 10” round duct
2nd. 8” round duct
3rd. 3-1/4” x 14” duct
4th. 7” round duct
5th. 3-1/4” x 10” duct
6th. 6” round duct
GThe use of flexible metal round duct
should only be used when no other duct
fitting exists. Limit use to short lengths
and do not crush when making corners.
GBack to back elbows should be avoided.
DUCTWORK INSTALLATION
GUIDELINES
GWhere local codes permit, plastic pipe
(PVC-schedule 40 pipe or ABS pipe 7”
or 8” diameter) can be used in areas of
high ground moisture and in slab floors
to eliminate future rusting.
GUse only duct work constructed of mate-
rials that are acceptable by the applica-
ble codes. All duct should be 26 gauge
or heavier to minimize flex due to air
flow.
GThe remote blowers require a 10” or 6”
diameter round duct (depending on
model) to match the inlet ring. A transiti-
on is necessary from other duct sizes.
GUse sheet metal screws as required to
support the duct weight, and seal all
joints with duct tape.
GBe certain that the duct work does not
interfere with floor joists or wall studs.
GDo not exhaust more than one vent into
a single duct run.
GCold weather installations should have
an additional 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 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.
GAlways use an appropriate roof or wall-
cap with damper. Laundry type wall caps
should never be used.

Step 2: Prepare Countertop Cutout
Refer to the cooktop installation instructions
for dimensions of cooktop, countertop cut-
out, and cabinet requirements prior to
making any cutouts. Cooktop depth and
countertop back-splash depth can vary
greatly from one to another. These variati-
ons may cause the fit of the downdraft and
cooktop to be tight. A countertop (front
edge) with a raised lip and/or a wide backs-
plash (back edge) may not allow enough flat
countertop for a proper installation.
YCheck that the cooktop is far enough
forward that the downdraft will fit behind
it. Verify all dimensions prior to cutting
the countertops.
Use the physical products to confirm
cutouts whenever possible.
For all installations verify that all cutouts will
clear the inside of the front countertop sup-
port rail, and that the cooktop and vent will
be centered left to right within the cutout.
Also, make certain that the front
and rear cutouts are straight and parallel to
the front edge of countertop and the rear
backsplash and/or wall. Assure that the
side cutouts are square to the front and rear
cutouts.
All illustrations and dimensions are based
on standard 24” deep by 36” high American
style base cabinets with 25” countertops.
When installing laminated or solid surface
countertops such as Surell™ and Corian®,
be sure to follow the countertop manufac-
turer’s instructions regarding minimum
comer radii, reinforcement of corners, etc.
Note: Check boxes as tasks are completed.
For overhead cabinet and cooktop side
clearances consult cooktop Installation
Instructions.

10
Notes
Dimension ”SB” is the minimum distance from the leading edge of the counter to the leading
edge of the cutout.
Dimension ”BT” is the thickness of backsplash that provides 1/4” clearance between vent
and backsplash. Any backsplash with a curved radius where it meets the counter will require
additional clearance. Thicker backsplashes may be used by increasing the counter and cabi-
net depths.
Set the cooktop into the countertop opening so that the back edge of the cooktop overlaps
the leading edge of the downdraft.

Step 3: Prepare Duct Cutouts in
Cabinet
YA. 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. Construct
two reference lines through this point:
one should be parallel to the cabinet
front and directly below the rear counter-
top cutout (Line A-A), and the other (Line
B-B) should be at right angles to A-A.
YB. 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 allows best
clearance from wall studs, floor joists,
utilities, or other obstructions.
Step 3: Prepare Duct Cutouts in
Step 3: Cabinet
YC. Before cutting for ducting, temporarily
set intake and cooktop in place and
attach integral blower (or duct transition
fitting if a remote or inline blower is instal-
led). 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.
YD. Remove temporarily placed hardware
and make cutouts in cabinet to accom-
modate ductwork installation.
YE. Make all other cabinet modifications
needed to provide proper clearances for
drawers or removable shelving.
Note: Check boxes as tasks are completed.

Step 4: Install Ductwork (Remote or
Inline Blower, If Used)
YA. Install the ductwork and remote blo-
wer (if used) in accordance with the duc-
twork routing plan developed in Step 1.
YB. 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.
YC. If using Integral Blower, proceed to
Step 5.
YD. If using Remote or Inline Blower, refer
to Installation Instructions with that
model.
Step 5: Install Electrical Service
YCheck 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-
Installation Codes for Gas Burning Appli-
ances and/or local codes).
YThe 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.
몇WARNING – 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-
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.
YThe 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
YA. Remove grease filters and any
packing materials from inside the intake.
YB. Set the vent intake into rear of coun-
tertop opening. Carefully lower it into
position so that the flanges on the rear
sides and edges fully support the unit
hanging from the countertop.
YC. 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.

Step 8: Verify Installation, Operation
and Cooktop Alignment
YBefore performing this procedure, verify
that all packing materials were removed
from inside the snorkel and that the grea-
se filters and front panel have been pro-
perly installed. Refer to the Care and Use
Manual for instructions regarding filter
and front panel installation.
YPlug the vent power cord into a proper
electrical receptacle and ensure that the
circuit is energized.
YA. Raise the snorkel to its fully extended
position by pressing the UP/DOWN
push-button once. Do not hold the push-
button. The elevating motor will stop
when the snorkel reaches its full height.
(Note: the blower will not operate unless
the snorkel is fully raised).
YB. Remove protective tape from top cap.
YC. Turn the blower ON by selecting in
turn each of the 3 speeds. Let the blo-
wer run several minutes at each speed to
evaluate its operation.
YD. With the blower running, lower the
snorkel to its fully retracted position by
pressing the UP/DOWN push-button
once. The blower will immediately turn
off.
Step 8: Verify Installation, Operation
and Cooktop Alignment
YE. With the blower on HIGH, close the
windows and doors to the area to ensure
that fan does not cause back drafting in
any outlet vent for another appliance.
YF. Raise and lower the vent again, and
check to make sure that the top cap on
the snorkel does not catch on the back
edge of the cooktop when it is lowered. If
interference occurs, adjust the position
of the cooktop by moving it against the
front edge of the countertop. Failure to
eliminate interference may result in per-
manent damage to the vent. Also, ensu-
re that the vent support legs have been
properly secured to the cabinet base
using the screws provided.
몇If the vent system does not operate
satisfactorily during any of the above proce-
dures, review all steps in these Installation
Instructions to ensure that nothing has been
omitted or overlooked. Also, refer to the
Care & Use Manual for additional informati-
on or call Thermador Customer Support 1-

INTRODUCTION
DESCRIPTION GÉNÉRALE
Le système de contre-tirage complet com-
prend le contre-tirage, une soufflerie et une
boîte de transition si l'on utilise une souffle-
rie en conduite ou à distance. Un module
de recirculation est également disponible
lorsque la mise en place de conduits vers
l'extérieur n'est pas privilégiée ou est
impossible. (Voir fig. 1).
La soufflerie peut être soit intégrée (montée
sur l'entrée d'évent dans l'armoire sous la
table de cuisson), en conduite montée entre
la cuisine et le mur extérieur à l'intérieur du
conduit), ou à distance (montée sur le toit ou
le mur extérieur). Lorsqu'une soufflerie à dis-
tance ou en conduite est utilisée, une transi-
tion de conduit est fixée sur l'entrée de venti-
lateur au lieu d'une soufflerie intégrée pour
brancher l'entrée sur le conduit. La transition
de conduit doit être achetée séparément.
La soufflerie intégrée ou la transition de
conduit peut être monté dans différentes
positions sur l'entrée pour acheminer le
conduit afin d'éviter l'armoire, la structure
de l'édifice, les services publics, etc.
Le système de contre-tirage est disponible
en 30 ou 36 po. Il est prévu pour être utilisé
uniquement avec des tables de cuisson
non professionnelles.
Un kit de recirculation peut être acheté
séparément et utilisé parallèlement à la souf-
flerie intégrée si le conduit posé vers l'exté-
rieur ne constitue pas une option viable.
Étape 1 : plan d'installation
Suivre attentivement le processus de planifi-
cation indiqué ci-dessous (voir figure 2). Les
schémas n'ont PAS pour fonction de tenir
lieu de planification soigneuse.
A. Déterminer si une soufflerie à distance,
en conduite ou intégrée est utilisée.
L'installation d'une soufflerie à distan-
ce et en conduite requiert 4 fils plus
un fil de mise à la terre allant du sys-
tème de contre-tirage à la soufflerie.
B. S'assurer que l'espace d’armoire et de
plan de travail est adéquat et que l'en-
trée et la soufflerie sont accessibles si
une réparation est requise
C. Il faut considérer les courants d'air créés
par les fenêtres ouvertes, portes, climati-
seur, évents de chauffage anciens, éclai-
rages encastrés et le trafic pouvant
réduire le rendement.
D. Pour les installations de tables de cuisson
à gaz, s'assurer qu'une ouverture minimale
de 10 po2 est prévue au coup-de-pied ou
autre armoire. Une ventilation inadéquate
de l'armoire sous la table de cuisson peut
causer l'extinction de la flamme au
moment d'actionner le système d’évent.
E. Assurer une alimentation en air dans
la pièce où l'appareil est installé. Si
l’air d'appoint n’est pas assuré, alors
il peut en résulter des problèmes
comme un contre-tirage de la chemi-
née du foyer.

F. Vérifier les chemins de conduit potentiels
et choisir le plus court possible depuis
l'appareil au mur extérieur ou au toit par
un mur intérieur et le grenier. À des fins
d'aide, des installations de conduit
typiques sont montrées aux figures 3 à
6. L'installation pour un îlot requiert un
conduit sous le plancher. Les emplace-
ments péninsules requièrent habituelle-
ment des conduits latéraux par les
armoires ou sous la base des armoires. Il
faut prendre en considération les interfé-
rences potentielles des conduits par la
structure de l'édifice (montants de plan-
cher ou de mur) et les services publics
(câblage électrique, eau, gaz, ou
conduites d'égout, etc.).
G. Acheter les conduits nécessaires pour
raccorder les conduits vers l'extérieur ou
acheter le module de recirculation de
contre-tirage séparément si le raccorde-
ment des conduits vers l'extérieur n'est
pas une option viable.
• S’assurer d'éviter une inter-
férence avec le gaz et l'ali-
mentation électrique à la
table de cuisson.
• La profondeur de la tablette
et du tiroir est dépendante
de la profondeur et du retrait
de la table de cuisson.
