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.
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
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 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.
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 be-
ing 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.
The equivalent
feet of various
roof and wall caps
has
been taken into consideration.
Do not include them in this
calculation.
