Internal Blower Installation
This downdraft blower system is
designed to be used to exhaust
airborne contaminants when
cooking with a variety of gas
or electric cooktops. It can be
mounted in island, peninsula,
or conventional wall locations.
This unit can be easily installed
following these basic steps:
• Cut out the countertop
opening.
• Mount the unit in the cabi-
net.
• Connect the ductwork and
electrical.
• Install the cooktop.
Note: the high level of air flow
of this appliance may effect the
gas flame on some types of gas
cooktops. This is NORMAL and
will cause no harm, but can be
corrected by lowering the speed
of the blower.

TAKE MEASUREMENTS

All Units
1. Refer to the cooktop installation instructions for dimensions
of cooktop, countertop cut-out, and cabinet requirements.
Models RMDD3004 & RMDD3004EX will fit in most 30" wide
cabinets. Models RMDD3604 & RMDD3604EX will fit in most
36" wide cabinets. Models RMDD4804 & RMDD4804EX will
fit in most 48" wide cabinets. However, it is recommended that
oversized cabinets be used for easier installation.
2. 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 high-
lighted 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 2-3/8" of flat countertop is required behind
cooktop and that 1-3/4" is necessary between the back edge of
the cooktop and the inside of cabinet back.
