PLANNING - (continued)
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 2830 will fit in most 30" wide cabinets and the Model
2836 will fit in most 36" wide cabinets. However, it is recom-
mended 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" 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
Install downdraft with an exterior blower that draws 6.0 AMPS
or less.
1. This downdraft blower system is most efficient when used
with 10" round ductwork. Use a combination of elbows and
transitions (shown below), closest to the downdraft, in order
to get from 3¼" x 10" to 10" round as soon as possible.
2. For best performance: Choose the ducting option which al-
lows 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.

3. The system will operate most efficiently when the ductwork
does not exceed 40 feet of equivalent duct. The illustrations,
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.
4. Refer to instructions packed with exterior blower or in-line
blower for additional information.
PLAN THE WIRING
1. The downdraft and exterior blower system normally draws 6
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 2830 is be-
ing installed in a 30" wide cabinet or the Model 2836 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.
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.

ing with a variety of gas or electric
cooktops. It can be mounted in
island, peninsula, or conventional
wall locations.
This system can be easily installed
following these basic steps:
•
Cut out the countertop opening.
• Mount the unit in the cabinet.
• Install exterior or in-line blower
• Connect the ductwork and
electrical.
• Install the cooktop.
