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.

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.

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 2-3/8" 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 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.
