DOWNDRAFT
DUCTWORK
The downdraft blower system is designed for use with 8" round ductwork using a Flex Blower or 10" round ductwork using a remote blower.
(Purchase blowers separately.) Seven (7) different discharge connections are available - with side-to-side adjustment for accurate alignment
of ductwork:
A = 8" Round, Left Discharge out of Flex Blower
B = 8" Round, Right Discharge out of Flex Blower
C = 8" Round, Down Discharge out of Flex Blower (Electrical Panel to be mounted remotely)
D = 1-7/8" x 19", Left Discharge out of Housing to Remote Blower or Flex Blower in remote location. Use 1-7/8" x 19" to 8" round transition,
1-7/8" x 19" to 10" round transition, or 1-7/8" x 19" ductwork as appropriate.
E = 1-7/8" x 19", Right Discharge out of Housing to Remote Blower or Flex Blower in remote location. Use 1-7/8" x 19" to 8" round transition,
1-7/8" x 19" to 10" round transition, or 1-7/8" x 19" ductwork as appropriate.
F = 1-7/8" x 19", Rear Discharge out of Housing to Remote Blower or Flex Blower in remote location. Use 1-7/8" x 19" to 8" round transition,
1-7/8" x 19" to 10" round transition, or 1-7/8" x 19" ductwork as appropriate.
G = 1-7/8" x 19", Below Discharge out of Housing to Remote Blower or Flex Blower in remote location. Use 1-7/8" x 19" to 8" round transition,
1-7/8" x 19" to 10" round transition, or 1-7/8" x 19" ductwork as appropriate.
For best performance: Choose the ducting option which allows the shortest length of ductwork and a minimum number of elbows and
transitions. Check location of floor joists, wall studs, electrical wiring or plumbing for possible interference.

Remote blowers
use 8" or 10" round
remote discharge
plate instead of flex
blower.
Refer to the cooktop installation instructions for dimensions of cooktop, countertop cut-out, and cabinet requirements. However, it is recommended
that oversized cabinets be used for easier installation. Custom island designs need to account for deeper cabinets - especially when installed with
a range in front of the downdraft or when mounting the blower behind the downdraft. You must also plan for an access door.
Cooktop depth can vary greatly from one to another. This may cause the fit of these two appliances to be rather tight.
Pay special attention to the areas of potential interference highlighted above. A countertop with (A) a raised lip and/or (B) a backsplash may not
allow enough flat countertop for a proper installation. Note that 2-3/4" of flat countertop is required behind cooktop and that 2-7/8" is necessary
between the back edge of the cooktop and the inside of cabinet back.
