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
recircuIation 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 wail anywhere within
the duct line), or a remote (mounted on the
roof or outside wail). 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-
grai 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, inIine, 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.

• 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,

Fig. 2
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 wali 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
potentiai interferences to ductwork from
building framing (floor joists, wali 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.

DUCTWORK INSTALLATION GUIDE-
LINES
•Ducting 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.
• Keep duct runs as short and straight as
possible.
• Duct fittings (elbows and transitions)
reduce air flow efficiency.
• Back to back elbows and "S" turns give
very poor delivery and are not recom-
mended,
• A short straight length of duct at the inlet
of the remote blower gives the best deli-
very.
• Transition 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
• The 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.
• Back to back elbows should be avoided,
• Where 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.
• Use 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.
• The 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.
• Use sheet metal screws as required to
support the duct weight, and seal all
joints with duct tape.
• Be certain that the duct work does not
interfere with floor joists or walI studs,
• Do not exhaust more than one vent into
a single duct run.
• Cold 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.
• Always use an appropriate roof or wail-
cap with damper. Laundry type wail caps
should never be used,

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 back,splash. Any back,splash with a curved radius where it meets the counter will require
additionai clearance. Thicker back,splashes may be used by increasing the counter and cabi-
net depths.
Set the cook,top into the countertop opening so that the back`edge of the cook,top overlaps
the leading edge of the downdraft.

Point "P"
Fig. 8
Step 3: Prepare Duct Cutouts in
Cabinet
[] A. Refer to Figure 8. Drop a pIumbqine
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.
[] 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 allows best
clearance from wall studs, floor joists,
utilities, or other obstructions.
[] C. 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.
[] D. Remove temporarily placed hardware
and make cutouts in cabinet to accom-
modate ductwork installation.
[] E. Make all other cabinet modifications
needed to provide proper clearances for
drawers or removable shelving.
Note: Check boxes as tasks are completed.

Canada,installationmustbeinaccor-
dancewiththeCAN1-B149.1and.2-
Installation Codes for Gas Burning Appli-
ances and/or local codes).
[] 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 piug-
ged into an outlet that is properly instal-
led and grounded.
/_k 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. Ifthe power
supply cord is too short, have a qualified
electrician install an outlet near the applian-
ce.
Step 6: Mount Vent and Cooktop
[] A. Remove grease filters and any
packing materials from inside the intake.
[] B. 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.
[] 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.

DESCRIPTION GC:NC:RALE
Le systeme de contre-tirage complet com-
prend le contre-tirage, une soufflerie et une
boTtede transition si I'on utilise une souffle-
tie en conduite ou a distance. Un module
de recirculation est egalement disponible
Iorsque Ia mise en place de conduits vers
I'exterieur n'est pas privilegiee ou est
impossible. (Volt fig. 1).
La soufflerie peut _tre soit integree (montee
sur I'entree d'event dans I'armoire sous Ia
table de cuisson), en conduite montee entre
Iacuisine et lemur exterieur a I'interieur du
conduit), ou a distance (montee sur Ietoit ou
lemur exterieur). Lorsqu'une soufflerie a dis-
tance ou en conduite est utilisee, une transi-
tion de conduit est fixee sur I'entree de venti-
Iateur au Iieu d'une soufflerie integree pour
brancher I'entree sur le conduit. La transition
de conduit dolt _tre achetee separement.
La soufflerie integree ou Iatransition de
conduit peut _tre monte dans differentes
positions sur I'entree pour acheminer le
conduit afin d'eviter I'armoire, la structure
de I'edifice, les services publics, etc.
Le systeme de contre-tirage est disponible
en 30 ou 36 po. IIest prevu pour _tre utilise
uniquement avec des tables de cuisson
non professionnelles.
Un kit de recirculation peut _tre achete
separement et utilise paralletement a la souf-
flerie integree si Ie conduit pose vers I'exte-
rieur ne constitue pas une option viable.
I_tape 1 : plan d'installation
Suivre attentivement le processus de planifi-
cation indique ci-dessous (volt figure 2). Les
schemas n'ont PAS pour fonction de tenir
lieu de planification soigneuse.
A. Determiner si une soufflerie a distance,
en conduite ou integree est utiIisee.
L'installation d'une soufflerie &distan-
ce et en conduite requiert 4 ills plus
un fil de raise & la terre allant du sys-
t_me de contre-tirage & la soufflerie.
B. S'assurer que I'espace d'armoire et de
plan de travail est adequat et que I'en-
tree et Ia soufflerie sont accessibles si
une reparation est requise
C. IIfaut considerer les courants d'air crees
par les fen_tres ouvertes, portes, climati-
seur, events de chauffage anciens, eclai-
rages encastres et Ietrafic pouvant
reduire le rendement.
D. Pour Iesinstallations de tables de cuisson
gaz, s'assurer qu'une ouverture minimale
de 10 po2 est prevue au coup-de-pied ou
autre armoire. Une ventilation inadequate
de I'armoire sous Iatable de cuisson peut
causer I'extinction de la flamme au
moment d'actionner Iesysteme d'event.
E. Assurer une alimentation en air dans
la piece oQ I'appareil est installS. Si
I'air d'appoint West pas assure, alors
il peut en r_sulter des probl_mes
comme un contre-tirage de la chemi-
n_e du foyer. 19
