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.

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

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 installa-

tion.

2. Cooktop depth can vary greatly from one to another. This may

cause the fit of these two appliances to be rather tight.

Install downdraft with an exterior blower that draws 6.0 AMPS or

less.

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.

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 being

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.

DISCHARGE

1. This downdraft blower system is most efficient when used with

10" round ductwork. Use a combination of elbows and transi-

tions (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 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.
