INTRODUCTION Step 1 PLAN THE INSTALLATION
GENERAL DESCRIPTION
The complete downdraft system consists 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 transi-
tion 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.
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 mini-
mum 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,

Investigate potential ductwork routes and choose the G.
shortest possible route from the unit to an outside wall
or to the roof via an inside wall and attic. For guidance,
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, H.
etc.).
Determine whether the chosen route of ducting will meet
vent system performance requirements. To do this,
measure the duct lengths needed and determine spe-
cific fittings required. Enter this data in the spaces
provided in addition, the duct installation guidelines in
Table 2 (See Page 6) should be followed in developing
the ductwork plan.
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 blower or remote
duct transition as close to the downdraft as is pos-
sible. 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.
Where local codes permit, plastic pipe (PVC-schedule
40 pipe orABS 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 airflow.
The remote blowers requires a 10" or 8" diameter
round duct (depending on model) to match the inlet
ring. A transition 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 wall studs.
Do not exhaust more than one vent into a single duct
run.
Thermal breaks, such as a short section of nonmetal-
lic 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.
Step 2: Prepare Countertop Cutout
For installation with a Thermador cooktop, refer to Part A(at
left) and Figure 7 (Page 7)). For installation with another
brand of cooktop, refer to Part B (Page 8).
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 backs-
plash and/or wall. Assure that the side cutouts are square
to the front and rear cutouts. All illustrations and dimen-
sions 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 TM and Corian ®, be sure to follow the countertop
manufacturer's instructions regarding minimum corner radii,
reinforcement of corners, etc.
For overhead cabinet and cooktop side clearances
consult cooktop Installation Instructions.
A, FOR INSTALLATION WITH A
THERMADOR COOK TOP (FIGURE 7
AND TABLE 3)
Provide an opening in the countertop as specified in
Table 3 (Page 8). 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".

Table 2 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,

B. FOR INSTALLATION WITH ANOTHER BRAND OF COOKTOP (Figure 8)
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 Overall Width
COD = Cooktop Overall 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
CVS230 /UCV230 283/8
CVS236 /UCV236 343/8
CVS245 /UCV245 433/8
If CCW is larger than the CVS2 /UCV2 cutout width
then:
CW = CCW
See Figure 8 for CVS2 /UCV2 cutout widths and
dimension definitions,
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 or45".
OD is determined by: OD=COD+21/8 ",
6. Cut countertop using dims: CD, CW and SB as
defined in Figure 8,

Table 4: Cabinet Cutout Dimensions
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 counter-
top cutout (Line A-A), and the other (Line B-B) should
be at right angles to A-A.
C,
wall studs, floor joists, utilities, or other obstructions,
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.
B, Using these reference lines as a base for the measure-
ments 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
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,
Page 9

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 installa-
tion 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 VTN600CV2C, 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 instal-
lation. In the U.S., if there are no applicable local codes,
this unit should be installed in accordance with the National
Electric CodeANSI/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 Appli-
ances and/or local codes).
The appliance must be grounded. In the event of an electri-
cal 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 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.
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.

Step 9 Verify Installation, Operation and
Cooktop Alignment
Before performing this procedure, verify that all packing
materials were removed from inside the snorkel and that the
grease filters and front panel have been properly installed.
Refer to the Care and Use Manual for instructions regarding
filter and front panel installation.
Plug the vent power cord into a proper electrical receptacle
and ensure that the circuit is energized.
A. Raise the snorkel to its fully extended position by
pressing the UP/DOWN push-button once (Figure 12).
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).
B. Remove protective tape from top cap.
C. Turn the blower ON by selecting in turn each of the 3
speeds. Let the blower run several minutes at each
speed to evaluate its operation.
D. 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.
E. 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.
F. 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
cutout, then re-secure the cooktop to the countertop.
Failure to eliminate interference may result in
