Refer to the cooktop installation instructions for dimensions of
cooktop, countertop cut-out, and cabinet requirements. The
RMDD3004 can be installed in most standard 30" wide cabinets,
(RMDD3604 can be installed in most standard 36" wide cabinets),
(RMDD4804 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.
* Dimensioned from top
of countertop
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 13/4"from
the cooktop and 2" of FLAT countertop is needed behind cooktop.

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 31/4"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.
