Venting Methods - KitchenAid KXD4630YSS0 Use & Care Manual

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 UX11200DYS (1200 cfm) are available
from your dealer or authorized parts supplier. See "Blower motor
system" in the "Accessories" section.
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.

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 ° elbows = 10.0 ft (3 m)
10 ft (3 m) straight = 10.0 ft (3 m)
Length of 10" (25.4 cm) = 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.
