Venting Requirements
IMPORTANT: Make sure there is proper clearance within the wall
or floor before making exhaust vent cutouts.
■Use heavy (rigid) metal vent.
■Venting system must terminate to the outside.
■Do not terminate the vent system in an attic or other
enclosed area.
■Do not use 4" (10.2 cm) laundry-type wall caps.
■Do not install 2 elbows together.
■Do not use plastic or metal foil vent.
■The length of vent system and number of elbows should
be kept to a minimum to provide efficient performance.
■Use no more than three 90° elbows.
■Make sure there is a minimum of 24" (61 cm) of straight vent
between the elbows if more than one elbow is used.
■Use clamps or duct tape to seal all joints in the vent system.
■Use caulking tape to seal the exterior wall or floor opening
around cap.
■Do not cut joist or stud. If vent cutout falls over a joist
or stud, a supporting frame must be constructed.
Flexible metal vent is not recommended. If it is used, calculate
each foot of flexible vent as 2 ft (0.6 m) of rigid metal vent.
Flexible elbows count twice as much as standard elbows.
Recommended vent system length:
For either interior-mounted or exterior-mounted blower
installations, the vent system length should not exceed the
maximum lengths listed in the “Maximum Length of Vent
System” chart. See “Calculating Vent System Length” in the
“Venting Methods” section in the Installation Instructions for the
interior- or exterior-mounted vent motor.
Cold Weather Installations
An additional backdraft damper should be installed to minimize
backward cold airflow and a thermal break should be installed
to minimize conduction of outside temperatures as part of the
vent system. The damper should be on the cold air side of the
thermal break.
The break should be as close as possible to where the vent
system enters the heated portion of the house.
Makeup Air
Local building codes may require the use of makeup air systems
when using ventilation systems greater than specified CFM of
air movement. The specified CFM varies from locale to locale.
Consult your HVAC professional for specific requirements in
your area.

Venting Methods
Determine which venting method is best for your application.
Vent system can terminate either through the wall or floor.
Island Location
NOTE: For island locations, a front- or rear-mounted blower
motor can also be mounted for right or left venting if needed for
your application. Most island applications would still require the
venting to be directed down through the floor.

INSTALLATION INSTRUCTIONS
EXTERIOR-MOUNTED VENT MOTOR
CAUTION: To reduce the risk of fire and electrical shock,
install the downdraft only with remote blower systems
that are sold by Whirlpool Corporation. Model numbers
UXI0600DYS (600 cfm) and UXI01200DYS (1200 cfm).
NOTE: Exterior-mounted vent motor installations require
an approved in-line blower motor system. Model numbers
UXI0600DYS (600 cfm) and UXI1200DYS (1200 cfm) are
available from your dealer or authorized parts supplier. See
“Blower motor system” in the “Accessories” section.
Venting Methods
Determine which venting method is best for your application.
Vent system can terminate through the wall or roof. A wall cap
or roof cap is required.
NOTES:
■Venting through a concrete slab is not recommended.
■The in-line blower motor system must be placed in
an enclosed area and can be located in a utility room,
basement, crawl space, or attic. Observe all governing
codes and ordinances.
■10" (25.4 cm) round vent duct is required for connections to
the retractable downdraft vent system outlet cover and the
in-line blower motor inlet and outlet covers. 10" (25.4 cm)
round vent duct is recommended for the retractable
downdraft vent system with in-line blower motor system.
Transitioning to different size ducting will reduce the
efficiency of the retractable downdraft vent system.

Calculating Vent System Length
It is recommended that you use round vent instead of rectangular
vent, especially if elbows are required. If rectangular vent is
required, it should be transitioned to 10" (25.4 cm) round vent
as soon as possible.
Maximum Length of Vent System
Vent Length
10" (25.4 cm) round 60 ft (18.3 m)
To calculate the length of the system you need, add the
equivalent feet (meters) for each vent piece used in the system.
Vent Piece 6" (15.2 cm) Round
45° elbow 2.5 ft
(0.8 m)
90° elbow 5.0 ft
(1.5 m)
The maximum equivalent vent lengths of 10" (25.4 cm) round
vents - 60 ft (18.3 m).
2 - 90° elbow = 10.0 ft (3 m)
10 ft (3 m) elbows = 10.0 ft (3 m)
Length of 10" (25.4 cm) system = 20 ft (6 m)
NOTE: The exterior-mounted vent motor requires a separate
wiring cable that should be installed at the same time the vent
work is installed.
