SAFETY INSTRUCTIONS
Read All Instructions Before Using the Appliance.
READ AND SAVE THESE INSTRUCTIONS
WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC
SHOCK, OR INJURY TO PERSONS, OBSERVE
THE FOLLOWING:
A. Installation work and electrical wiring must be done
by qualified person(s)in accordance with all appli-
cable codes and standards, including fire-related
construction.
B. Sufficient air is needed for proper combustion and
exhausting of gases through the flue (chimney) of
fuel burning equipment to prevent backdrafting.
Follow the heating equipment manufacturer's
guideline and safety standards such as those
published by the National Fire Protection Associa-
tion (NFPA), and the American Society for Heating,
Refrigeration and Air Conditioning Engineers
(ASHRAE), and the local code authorities.
C When cutting or drilling into wall or ceiling, do not
damage electrical wiring and other hidden utilities.
D. Ducted fans must always be vented to the outdoors.
E. Always unplug or disconnect the downdraft from the
power supply before servicing.
F. This unit is designed for indoor use only. Use this
unit only in the manner intended by the manufac-
turer.
This unit is manufactured for indoor use only. Do not use
this unit outdoors.
WARNING
CAUTION: Forgeneral ventilating use only. Do
not use to exhaust hazardous or explosive materi-
als and vapors.
To reduce risk of fire and to properly exhaust air,
be sure to duct air outside. Do not vent exhaust
air into spaces within walls, ceilings, attics, crawl
spaces or garages.
TO REDUCE THE RISK OF FIRE, USE ONLY
METAL DUCT WORK.
To reduce the risk of fire, electric shock and injury
to persons, ventilator assemblies. All CVS2
models must be installed with integral blower,
Model VTN600CV2C or remote blowers model
VTR600R or VTR1000Q. Other ventilator blowers
cannot be substituted.
To reduce the risk of fire or electric shock, do not
use the fan with any solid-state speed control
device.
This appliance has been found to be in compli-
ance with UL507 Standard for Electric Fans and
CAN/CSA-22.2 No. 113 Canadian Standard for
Fans and Ventilators. It is the responsibility of the
owner and the installer to determine if additional
requirements or standards apply in specific
installations.

INTRODUCTION
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.
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 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,

Figure 2
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 inaccordance with
the listing developed in G above.
