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 2730 will fit in most 30" wide cabinets and the Model
2736 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.

DISCHARGE
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 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.
NOTE: The unit is shipped with the 3-1/4" x 10" discharge
facing DOWN. See "CHANGING BLOWER DIRECTION" on
page 3, 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 2730 is be-
ing installed in a 30" wide cabinet or the Model 2736 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.
