PLANNING -
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
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.

DUCT
PLAN THE DUCTWORK
LEFT
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
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 DI-
RECTION" on page 3, if necessary.

STRAIGHT DUCT
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
being 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.
