PLANNING
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 cabinet.
• Connect the ductwork and electrical.
• Install the cooktop.
I NOTE
The high level of air flow of this appliance may affect 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
1. Refer to the cooktop installation instructions for dimensions
of cooktop, countertop cut-out, and cabinet requirements.
The Model 59940 will fit in most 30" wide cabinets and the
Model 59946 will fit in most 36" 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
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" of flat countertop is required
behind cooktop and that 1-3/4" is necessary between the back
edge of the cool<top and the inside of cabinet back.

PLAN THE DUCTWORK
1. This downdraft blower system is designed
for use with
3-1/4" x 10" ductwork (can be transitioned
to 6" round)•
Three different discharge directions are available with side-
to-side adjustment for accurate alignment of ductwork.
2. For best performance:
Choose the ducting option which
allows the shortest
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. NOTE: The unit is shipped with the 3-1/4" x
10" discharge facing DOWN. See "CHANGING BLOWER
DISCHARGE" on page 7, if necessary.
3. 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 duct plus the equivalent feet
of transitions and/or elbows to be used should equal 40
feet or less.

PLAN THE WIRING
1. The downdraft blower system draws 4 AMPS and requires
a 120 VAC, 60 Hz circuit.
2. The unit has a 2 ft. long power cord with a 3-pronged plug•
Plan to provide a grounded outlet in a location which will
allow the unit's power cord to reach. (Note: If the Model 59940
is being installed in a 30" wide cabinet or the Model 59946 is
being installed in a 36" wide cabinet, the outlet cannot be
located on the back wall of cabinet.) Outlet may also be wall-
mounted, with access hole in cabinet.
