INSIDE CABINET DEPTH

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

A

behind cooktop and that 2-1/2" is necessary between the back edge of the cooktop
and the inside of cabinet back.

Use the dimensions in the above illustration to help plan
how and where to provide duct access through your
cabinet. Generally, 1-7/8" x 19" rectangular duct will be
used through left, right, and back of cabinet - while 8"
round duct will be used through cabinet floor.

For left, right, or rear exhaust:
Allow at least 18" for transition and elbow or blower.

For left / right exhaust:

A 30" deep cabinet is recommended to align properly
with flex blower. Flex blower can be mounted to rear
cabinet wall or to a platform / frame (not provided) on
the base of the cabinet floor. (See flex blower instruc­tions).

Cabinet depths of 24" to 30" are required - depending
on the type of cooking appliance.

ELECTRICAL PANEL

The unit has a 30-in. power cord with a 3-pronged plug.
Plan to provide a grounded outlet within reach of this cord.

BLOWER

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.) Six (6) different discharge connections are available - with side-to­side 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.

For best performance: Choose the ducting option which allows the shor test 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.
