PREPARE THE DOWNDRAFT LOCATION
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.
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
59960 will fit in most 30" wide cabinets and the Model 59966
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 cooktop 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.
NOTE
The equivalent feet of various roof and wall caps has been taken into
consideration. Do not include them in this calculation.
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.
