WARNING
To reduced 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 applicable 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 back-
drafting. Follow the heating equip-
ment manufacturer’s guideline and
safety standards such as those
published by the National Fired
Protection Association (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
appliance 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 manufacturer.
WARNING
For general ventilating use only. Do not
use to exhaust hazardous or explosive
materials 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 reduced the risk of fire, use only metal
duct work.
To reduce the risk of fire, electric shock
and injury to persons, ventilator
assemblies. All models must be installed
with integral blower, Model DHG601DUC
or remote blowers models
DHG6015DUC or DHG6023UC. 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
compliance with UL 507 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 standard
apply in specific installation.

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 and 36-inch models. It is intended
for use with all brands and models of
residential 30-inch or 36-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
Table 1 (see Page 8). In addition, the
duct installation guidelines 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.

Step 2: Prepare Countertop Cutout
For installation with a Bosch cooktop, refer
to Part A and Figure 7 (Page 12).
For installation with another brand of cook-
top, 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 cooktop (Figure 7
and Table 2)
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 thickn-
ess does not exceed dimension “BT”.
