■ There are 7/8” access holes in the bottom and side of the downdraft
vent for connecting the blower wiring and strain relief. The blower
must be wired to turn on when the downdraft vent is turned on. When
installing a remote or in-line 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.
■ 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.

Duct Work Design Considerations
■ For optimal performance, consult a qualified HVAC specialist when
designing the duct system.
■ All duct work materials (including screws and duct tape) must be
purchased separately by the customer.
■ Cross-drafts or air currents from adjacent open windows or doors,
heating/air conditioning outlets, ceiling fans and recessed ceiling lights
reduce vent efficiency.
■ When planning the cabinet layout, allow room for the exhaust duct
coming out of the unit. Always look for the shortest, most direct route
to the outside.
■ Do not use flexible metal duct.
■ 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 required.
■ If multiple elbows are used, try to keep a minimum of 24” of straight
duct between them. Avoid “S” or “back to back” configurations of
adjacent elbows.
■ 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.
■ 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.
■ System exhaust location must take into account accumulated
snowfall, where applicable.
Revised 02/28/14 Page 7/7
PLANNING
GUIDE
Calculating the Maximum Duct Run Length
■ Do not use duct work that is smaller in cross-sectional area than the
required duct sizes in the Blower Maximum Duct Straight Length
table below. For best performance, keep the duct run as short as
possible and never exceed the maximums stated.
■ The maximum straight duct length for the downdraft vent system
depends on the model of remote or in-line blower used with the
vent system and the number of elbows and transitions used. The
Equivalent Number of Feet for each elbow and transition 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 from the Blower Maximum Duct Straight Length.
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, 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.
