ADVANCE PLANNING
Design Information
Remote Switch
The downdraft vent has a separate raise/lower switch.
Plan to install the switch in a convenient location
outside of the vent/cooktop cutout.
Downdraft Vent and Cooktop Cutout
The installation of these downdraft vents with any
Monogram cooktop requires careful consideration. For
accurate planning, this book provides individual
dimension drawings for the vent and the Monogram
cooktop combined installation.
Countertop Requirements:
The countertop must have a deep flat surface to
accommodate the cooktop and the vent. Countertops
with a rolled front edge and backsplash may not
provide the flat surface area required.
Base Cabinet Requirements:
The base cabinet must be deep enough to accommodate the minimum clearance to the front of the
countertop, the cooktop burner box and the vent.
Creative Solutions
• When the kitchen design calls for an against the
wall installation, move the base cabinet forward, 3”
to 5”. Filler panels or complimentary moldings can
be added to exposed cabinet sides.
Before you begin, you must:
1. Review countertop dimension illustrations to be
sure you will have enough flat countertop surface.
2. Check to be sure that the total countertop depth
required (including minimum cutout to front edge
depth) allows enough space for a backsplash.
3. Review the cabinet illustration. Check to be sure
the interior cabinet depth will house the cooktop
burner box, the vent and the cutout clearance from
the front.
4. When countertop and cabinet depth present a
problem, review
5. Read this book completely to accurately plan the
installation location, clearances and ductwork
requirements.
With careful planning you can achieve a custom look
with minimal adjustments.
Creative Solutions.
Maintain Cutout Clearances
to Front Edge as Specified
• In an island or peninsula, use an extra deep
countertop. The countertop overhang at the
front can be adjusted to meet setback to cutout
requirements.
• When the cutout to front edge of the countertop
requirement is more than 2", add a bullnose trim to
the front edge of the countertop. Include the trim
thickness when measuring front edge to cutout
requirement. By adding the trim, the cooktop can be
moved forward, providing additional countertop
depth and interior cabinet space.

Design Information
Clearances
• The downdraft system with blower, motor and duct
work will occupy the cabinet below the countertop
and cooktop.
• The blower/motor assembly can be located below
the cabinet floor. The assembly will fit between 16”
floor joists. Order JXRB67 for indoor remote
locations.
• The blower motor assembly can also be installed
outdoors. Order JXBC67 for remote blower installations outdoors.
• Refer to “Cooktop Clearances” for information on
appropriate placement and necessary clearances
when planning installation.
• Refer to your specific cooktop installation instruction for other appropriate clearances.
• Avoid placing cabinetry directly above the cooking
surface when possible.
If cabinetry is used above the cooking surface:
• Use cabinets no more than 13” deep.
• Maintain 30” minimum clearance between cooktop
and unprotected cabinets directly above cooktop.
• If clearance is less than 30”, protect cabinet bottoms with flame-retardant millboard at least 1/4”
thick or gypsum board at least 3/16” thick covered
with 28 gauge sheet steel or .02” thick copper.
• Clearance between cooktop and protected
cabinetry must not be less than 24.”
EXCEPTION: Installation of a listed microwave oven
or cooking appliance over the cooktop shall conform
to the installation instructions packed with that
appliance.
• Working areas adjacent to the cooktop should 18”
minimum clearance between countertop and
cabinet bottom.
• Installation must conform with local codes.
Ductwork
Prepare ductwork to vent to the outdoors.
• Use the shortest and straightest duct run possible.
• The maximum permissible length for duct run is 150
feet.
• Refer to “Duct Fittings” chart to calculate equivalent
length for various duct configurations.
• The downdraft blower system is designed to use
3-1/4” x 10” ductwork. It can be transitioned to
6” round.
• Ductwork MUST be vented to the outside–never into
a crawl space, attic or other enclosed space.
• Determine the need for a wall cap or roof cap. Order
the cap in advance.
Electrical and Gas Locations
Plan the placement of the electrical outlet and gas
(if used) carefully. Gas or electrical outlets cannot be
placed on the back wall of the cabinet because it may
interfere with the downdraft plenum.
• Install a standard electrical outlet within reach of the
vents’ two foot long power cord.
• The vent and a Monogram gas cooktop combination
can operate from the same 120 volt standard duplex
outlet.
• Electric cooktops must operate from a separate
240 volt junction box.
