Installation Specifications
Planning the Installation
General System Layout
The vent system consists of the downdraft vent itself and a
single Dacor approved cabinet blower (models ERV3015 and
ERV3615), remote blower or in-line blower (see facing page
for examples).
WARNING
• Failure to install an approved blower or proper duct
work will result in a back draft and/or the insufficient
venting of smoke and fumes.
• To reduce the risk of personal injury caused by reaching over a hot appliance, cabinet storage space
located directly above the range/cooktop should be
avoided.
• Follow the instructions and diagrams for minimum safe
clearances and installation location in these instructions, the appliance installation instructions and the
blower installation instructions. Failure to do so may
result in a fire or safety hazard.
• Plan the installation so that all minimum dimensions
are met or exceeded. All contact surfaces between the
downdraft vent and any cabinets or walls must be solid
and at right angles.
• The downdraft vent is equipped with adjustable anchor
legs to accommodate various cabinet heights.
• Install the downdraft vent and range/cooktop so that
they can be removed if service is required.
• When installing the downdraft vent with a cooktop,
access from the front of the cabinet to the chassis and
the electrical/gas supplies of both appliances must
be provided for inspection and service. Any drawers
or shelves must be easy to remove for access to the
cooktop, downdraft vent and utilities.
• There are 7/8” access holes in the bottom and side of
the downdraft vent for connecting the blower wiring and
strain relief. Wire the blower to turn on when the downdraft vent is turned on. When installing a remote or inline blower, run the blower wiring/conduit parallel to the
duct work, connecting it to the downdraft vent on one
end and the blower on the other.
• Allow room for the exhaust duct coming out of the unit.
See Planning the Duct Work for further details.
• The maximum allowable duct run must be taken
into consideration when determining the layout. See
Planning the Duct Work for further details.
• Refer to the range/cooktop installation instructions for
the minimum cutout dimensions specific to the particular downdraft vent model being installed.

Planning the Duct Work
WARNING
• To reduce the risk of fire and to properly exhaust air,
be sure to duct air outside the house or building. Do
not vent exhaust air into spaces within walls or ceilings or into attics, crawl spaces or garages.
• TO REDUCE THE RISK OF FIRE, USE ONLY METAL
DUCT WORK.
• DO NOT install more than one blower to increase the
length of the duct run. Even small differences between
blower air flow rates can greatly reduce the air draw
by the downdraft vent.
Local building codes may require the use of makeup air
systems with ventilation systems that move air greater than
the specified movement rate (CFM). The specified rate varies based on locale. Consult a qualified HVAC specialist
when designing the system for the requirements in your
area and to assure optimal performance.
You must install one of the Dacor blower models listed
below for the downdraft vent to operate properly. See the
blower installation instructions for directions. For model
CABP3, see the instructions later in this manual.
Installations with ILHSF and REMP series blowers:
With ILHSF and REMP blowers, the downdraft vent can
be configured to exhaust through the back, the bottom or
either side by removing the appropriate exhaust knock-out
shown on the facing page.
• When connecting the duct work to the back of the unit,
the customer must supply a 3 ¼ x 10 rectangular transition to make the connection.
• For side and bottom exhaust connections, use the supplied transition to connect the duct work to the unit. It
transitions between the 1
unit and a 3 ¼ x 10 rectangular duct connection. On
bottom exhaust installations cut a hole in the floor to
allow the transition and/or duct work to pass through
the floor (see page 13).

Duct installation requirements for all blowers:
• All duct work materials (including screws and duct tape)
must be purchased separately by the customer.
• When planning new duct work, always look for the
shortest, most direct route to the outside. See page
7 for examples.
• You can increase the duct size over the duct run if
desired. To prevent a back draft, never decrease the
duct size over the run.
• Do not rely on duct tape alone to seal duct joints.
Fasten all connections with sheet metal screws and
tape all joints with certified silver tape or duct tape.
3”
C
L
• Use sheet metal screws as required to support the duct
weight.
• To prevent back-drafts, a damper at the duct outlet may
also be required.
• Make sure duct work does not interfere with floor joists
or wall studs.
• With concrete slab construction, “box-in” the duct work
and blower wiring to prevent collapsing or other damage when the wet concrete is poured.
• Cross-drafts or air currents from adjacent open windows or doors, heating/air conditioning outlets, ceiling
fans and recessed ceiling lights reduce vent efficiency.
• System exhaust location (see page 8) must take
into account accumulated snowfall, where applicable.

Installation Specifications
Calculating the Maximum Duct Run Length
• For optimal performance, consult a qualified HVAC
specialist when designing the duct system.
• Do not use duct work that is smaller in cross-sectional
area than the required duct sizes in the tables below.
• Keep the duct run as short as possible for best performance and never exceed the maximums stated in the
table below right.
• The maximum duct length for the downdraft vent system depends on the blower model used and the number of elbows and transitions. The Equivalent Number
of Feet for each elbow and transition (see table below)
must be subtracted from the maximum straight length
to compensate for wind resistance. To determine the
maximum allowable length of the duct work, subtract all
of the equivalent lengths of the elbows and transitions
listed below from the Blower Maximum Duct Straight
Length (see table right).
For example, for a downdraft vent system using 3 ¼ x 10
rectangular duct, two (2) 3 ¼ x 10 90° elbows, a 3 ¼ x 10
rectangular to 10” round transition, and a REMP16 remote
blower:
• From the Blower Maximum Duct Straight Length
table below, the maximum length without transitions
and elbows is 60 feet.
• The equivalent length of each 90° elbow is 15 feet.
• The equivalent length of 45° elbow is 2 feet.
• The equivalent length of the transition is 4 feet.
• The total equivalent length of the above components is:
15 feet + 15 feet + 4 feet + 2 feet = 36 feet.
• The maximum amount of straight duct that can be used
with a REMP16 and the above components is: 60 feet 34 feet = 24 feet.
Duct Work Design Tips
• Wherever possible, reduce the number of transitions
and turns to as few sharp angles as possible. Two
staggered 45° angles are better than one 90°. Keep
turns as far away from the hood exhaust as possible,
with as much space between each bend as possible.
• For best performance, use round duct instead of rectangular when possible, especially when elbows are
