INSIDE CABINET DEPTH

Refer to the cooktop installation instructions for dimensions of
cooktop, countertop cut-out, and cabinet requirements. The
DD0130SS can be installed in most standard 30" wide cabinets,
(DD0136SS can be installed in most standard 36" wide cabinets),
(DD0148SS can be installed in most standard 48" wide cabinets).

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 4 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. The back of the downdraft cut-out will be 1¾" from the
cooktop and 2" of FLAT countertop is needed behind cooktop.

The unit has an 18-in. power cord with a 3-pronged plug. Plan to
provide a grounded outlet within reach of this cord.

This downdraft blower system is designed for use with 3¼" x 10"
rectangular, or 6" round duct. The blower discharge can be
positioned in one of 3 directions with 7½" movement side to side.

The system will operate most efficiently when the ductwork does
not exceed 40 feet of equivalent duct. The chart above, shows
equivalent feet of elbows and transitions. The number of feet of
straight 3¼" x 10" or 6" duct plus the equivalent feet of elbows or
transitions to be used should equal 40 feet or less.

The equivalent feet of various roof and wall caps has been taken
into consideration. Do not include them in this calculation.
