INTRODUCTION
GENERAL DESCRIPTION
The complete downdraft system consits of
the ventilator, the intake and the blower
(See Fig. 1). The blower can be either
integral (mounted on the vent intake in the
cabinet under the cooktop) or a remote
(mounted on the roof or outside wall). When
a remote blower is used, a duct transition is
mounted on the ventilator intake in place of
the integral blower to connect the intake to
the ductwork. 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, 36-inch and 45-inch models. Black
or white top cap accessories are available
to change the color from the basic stainless
steel. It is intended for use with all brands
and models of residential 30-inch, 36-inch
or 45-inch gas or electric cooktops except
professional style cooktops.
Step 1: Plan the installation
Carefully follow the planning procedures
listed below (See Figure 2).
A. Determine whether a remote or integral
blower will be used. Remote 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 will be accessible if
service is required.
C. Consider that cross drafts created by
adjacent open windows, doors, air
conditioning, 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
cabinet 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 provided, 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
duidance, 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 toespaces. Consider
potential interferences to ductwork from
building framing (floor joists, wall studs,
etc.) and utilities (electrical wiring, water,
gas, or sewer lines, etc).
G. Determine whether the chosen route of
ducting will meet vent system
performance requirements. To do this,
measure the duct lengths needed and
determine specific fittings required. Enter
this data in the spaces provided in
addition, the duct installation guidelines
in Table 2 (See Page 9) should be
followed in developing the ductwork
plan.
H. Purchase the necessary ductwork in
accordance with the listing developed in
G above.

DUCTWORK INSTALLATION
GUIDELINES
❑ For safety reasons, ducting should vent
directly outdoors (not into an attic,
underneath the house, into the garage or
into any enclosed space).
❑ 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
recommended.
❑ A short straight length of duct at the inlet
of the remote blower gives the best
delivery.
❑ 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.
DUCTWORK INSTALLATION
GUIDELINES
❑ 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
materials that are acceptable by the
applicable codes. All duct should be
26 gauge or heavier to minimize flex due
to air flow.
❑ The remote blowers requires a 10” or 8”
diameter round duct (depending on
model) to match the inlet ring. A
transition is necessyary 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 wall studs.
❑ Do not exhaust more than one vent into
a single duct run.
❑ Thermal breaks, such as a short section
of nonmetallic duct, should be used in
areas of extreme cold.
❑ Always use an appropriate roof or
wall-cap with damper. Laundry type wall
caps should never be used.
10
Step 2: Prepare Countertop Cutout
For installation with a Thermador cooktop,
refer to Part A (at left) and Figure 7
(Page 12). For installation with another
brand of cooktop, refer to Part B (Page 13).
For all installations verify that all cutouts will
clear the inside of the front countertop
support 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
manufacturer’s instructions regarding
minimum comer radii, reinforcement of
corners, etc.
For overhead cabinet and cooktop side
clearances consult cooktop Installation
Instructions.
A. FOR INSTALLATION WITH A
THERMADOR COOKTOP
(FIGURE 7 AND TABLE 3)
Provide an opening in the countertop as
specified in Table 3 (Page 13). Make
sure that the distance from the front of
the countertop to the front of the cutout
is not less than dimension ”SB”. Verify
that the available flat countertop is
greater than dimensions “OW” by “OD”.
Make certain that the backsplash
thickness does not exceed dimension
“BT”.

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 cabinet depths.
All dimensions are in inches and are based upon a standard 24” deep base cabinet
with 25” countertop.
** SGS and SGSX: width in table is at the widest point (center).
Refer to cooktop Installation Instructions for complete information prior to making any
cutouts.

Have the following cooktop measurements
available before proceeding All cooktop
dimensions should be verified through measurement prior to cutting the
countertop:
CCW = Cooktop Cutout Width
CCD = Cooktop Cutout Depth
COW = Cooktop Oberall Width
COD = Cooktop Oberall Depth
with the above dimensions confirmed,
determine the cutout size as follows:
1. Find the cutout width, (CW):
If CCW is smaller than the CVS2 / UCV2
cutout width then:
Installation CW

If CCW is larger than the CVS2 / UCV2
cutout width then:
CW = CCW
See Figure 8 for CVS2 / UCV2 cutout
widths and dimension definations.
2. Calculate the cutout depth, CD:
Determine the cooktop overhang (CO)
CO = (COD-CCD)/2 (Assumes front and
rear cooktop overhangs are equal).
Calculate the cutout depth, (CD):
CD = COD - CO+1-
7
/8”
3. Determine setback (SB) distance from
front of countertop to front of cutout.
SB is specified in the installation
instructions shipped with the cooktop.
4. Backsplash thickness must not
exceed BT as calculated below:
BT = 24
7
/8” - OD-SB+CO
(Provides
1
/8” clearance between vent
and backsplash.) A negative value for BT
means countertop is too small for the
installation.
5. Verify that the available flat countertop
has a width greater than OW and a
depth greater than OD.
OW depends on the installation:
CVS230 / UCV230:
OW equals the
greater of COW or
30”.
CVS236 / UCV236: OW equals the
greater of COW or
36”.
CVS245 / UCV245:
OW equals the
greater of COW or
45”.
OD is determined by: OD = COD + 21/8”.
6. Cut countertop using dims: CD, CW
and SB as defined in Figure 8.

Step 3: Prepare Duct Cutouts in
Cabinet
A. Refer to Figure 9. 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 countertop 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 shown in Table 4,
layout the necessary cabinet cutouts
needed to implement 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
C. Temporarily set intake and cooktop in
place and attach integral blower (or duct
transition fitting if a remote 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.
D. Remove temporarily placed hardware
and make cutouts in cabinet to
accommodate ductwork installation.
E. Make all other cabinet modifications
needed to provide proper clearances for
drawers or removable shelving.
15
Step 4: Install Ductwork (Remote
Blower, If Used)
A. Install the ductwork and remote blower
(if used) in accordance with the ductwork
routing plan developed in Step 1.
B. Make sure that the installation complies
with all installations guidelines in Table 2.
Also check that the opening where duct
passes through outside wall or roof has
been properly flashed and sealed to
prevent leakage.
C. If using Integral Blower, Model
VTN600VC2C, proceed to Step 5.
D. If using Remote Blower Model VTR600R
or VTR1000Q, refer to Installation
Instructions with that model.
Step 5: Install Electrical Service
Check your local building codes for proper
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 accordance with the CAN 1-B149.1
and .2-Installation Codes for Gas Burning
Appliances and/or lodal codes).
The appliance must be grounded. In the
event of an electrical short circuit,
grounding 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 plugged into an outlet that is properly
installed and grounded.
WARNING – Improper grounding can result
in a risk of electric shock.
Consult a qualified electrician if the
grounding instructions are not completely
understood, or if doubt exists as to whether
the appliance is properly grounded.
Do not use an extension cord. If the power
supply cord is too short, have a qualified
electrician install an outlet near the
appliance.
The receptacle should be located under the
countertop so that the 30 inch long power
cord from the vent will reach it.
See Figure 9. 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
A. Remove grease filters and any packing
materials from inside the intake.
B. Set the vent intake into rear of
countertop opening. Carefully lower it
into position so that the flanges on the
rear sides and edges fully support the
unit hanging from the coluntertop.
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.
D. Place the cooktop in countertop opening
with the rear edge of cooktop
overlapping the front edge of the vent.
Make sure rear edge of cooktop does
not bind against front of snorkel.
Follow the manufacturer’s installation
instructions for installing gasket strips,
protective heat tape (if required),
securing the cooktop to the countertop
and making the cooktop electrical and/or
gas connections.
