Preparing for Rnstailation
Positioning the cooktop
The cooktop is designed to look best when centered
in a cabinet it's same width.
The exhaust vent beneath the cooktop must be locat-
ed between wall studs or floor joists so that ductwork
may be installed properly.
At least 6" must be allowed between side edges of
cooktop and adjacent walls.

to side
Avoid placing cabinets above the cooktop unit, if pos-
sible, in order to reduce the hazards caused by reach-
ing over heated surface units. If cabinets are placed
over the cooktop, the risks can be reduced by installing
a range hood that projects horizontally a minimum of 5
inches beyond the bottom of the cabinets.
If cabinetry is used above cooktop, allow a minimum
30" clearance between the cooking surface and the
bottom of any unprotected cabinet,
If clearance between cooktop and cabinetry is less
than 30'; cabinet bottom must be protected with flame
retardant millboard at least 1/4" thick, covered with 28
gauge sheet steel or 0.020" thick copper. Clearance
between cooktop and protected cabinetry must
NEVER BE LESS THAN 24"
A 15" minimum must be kept from the side edge of
cooktop to the bottom of any cabinet not directly above
cooktop. If clearance is less than 15", adjacent cabi-
nets should be at least 6" from side edge of cooktop.
Preparing the Base Cabinet
This cooktop is designed to fit easily into a variety of
cabinets. However, some cabinets may require modi-
fications.
Preparing a cabinet that is against a wall
In some cabinets, the sides may need to be scooped
or cut down 2" as shown, and the corner braces
removed in order to accommodate the unit.
In 75 cm. and 90 cm. frameless European cabinets,
the back panel may need to be cut down 5" to accom-
modate the unit.
Preparing a peninsula or island type cabinet

In general, the use of flexible ducting is discouraged
because it can cause severely restricted airflow.
However, if the blower outlet and the floor or walt duct
location do NOT align well, then flexible METAL duct-
ing can be used to adapt to an offset. Good alignment
without use of flexible ducting is best.
NOTE:
o DO NOT EXCEED THE MAXIMUM RECOMMEND-
ED OFFSET OF 3".
o DO NOT ALLOW THE FLEXIBLE DUCTING TO
KINK OR COLLAPSE.

Steps to Determine FHexible
Ducting's Equivalent Length
1. Measure the actual amount of offset (MAXIMUM 3"
RECOMMENDED). The effect upon airflow is
dependent upon the amount of offset.
2. Calculate the equivalent ducting allowances using:
(__ in. offset) x (14 Ft. per inch)
=_ Ft, equivalent length.
3. Enter the calculated value into TABLE 1 of this
installation instruction.
4. Ensure that the total equivalent length of ducting
does not exceed the maximum recommendation of
1O0 feet.

@
LnstaHing the Duct'work
Use minimum 26 gauge galvanized or 24 gauge alu-
minum duct in 6" round or 3W" x t0" size, or combina-
tion of both.
PVC duct should be used if installing under a poured
concrete slab.
NOTE: Local building code must be followed in speci-
fying approved type and schedule of PVC duct used.
5" round duct may be used on SHORT DUCT runs.
But, note higher equivalent lengths for each 5" dia.
piece used. Don't convert back to 5" duct after use of
6" round or 3'/.," x 10" duct.
Always use an appropriate roof or wall cap with
damper. Laundry type walt caps should NEVER by
used.

Select downward or wall venting. To convert blower
exhaust direction, remove four nuts inside the plenum
which hold blower and wire finger guard. Remove
blower and rotate so that exhaust faces downward or
rear direction needed. Replace wire finger guard and
nuts. Retighten nuts.
Blower exhaust direction can be adjusted slightly
while in its vertical or horizontal direction by loosen-
ing four nuts holding blower, rotating blower and
retightening nuts.
Use the shortest and straightest duct run possible. For
satisfactory performance the duct run should not
exceed t00 feet equivalent length, Refer to TABLE 1
of equivalent lengths. Use TABLE 1 to calculate the
total equivalent length of the ductwork,

Before Making Electrical Connections
Note to Electrician:
The power leads supplied with this appliance are U. L.
recognized for connection to large gauge household
wiring. The insulation of these leads is rated at tem-
peratures much higher than the temperature rating of
household wiring. The current carrying capacity of a
conductor is governed by the wire gauge and also the
temperature rating of the insulation around the wire.
Aluminum Wiring
WARNING: IMPROPER CONNECTION OF ALU-
MINUM HOUSE WIRING TO THE COPPER LEADS
CAN RESULT IN SERIOUS PROBLEMS.
Attach copper wires to aluminum wiring using special
connectors designed and U, L. listed for joining cop-
per to aluminum. Follow the connector manufacturer's
recommended procedure closely.

o Before performing any service, DISCONNECT
THE COOKTOP POWER SUPPLY AT THE
HOUSEHOLD DISTRIBUTION PANEL BY
REMOVING THE FUSE OR SWITCHING OFF
THE CIRCUIT BREAKER.
Do not leave children
alone or unattended
while the cooktop units
are in operation. They
could be seriously burned.
oDo not allow anyone to
climb, stand or hang on
the cooktop.
t{
CAUTION: ITEMS OF
INTEREST TO CHILDREN
SHOULD NOT BE STORED
IN CABINETS ABOVE THE
COOKTOP-- CHILDREN
CLIMBING ON THE COOKTOP
TO REACH THEM COULD BE
SERIOUSLY INJURED.
Never wear loose-fitting
or hanging garments
while using the cooktop.
Flammable material could
be ignited if brought in con-
tact with hot surfaces and
may cause severe burns.
Use only dry pot holders--moist or damp pot
holders on hot surfaces may result in burns from
steam. Do not let pot holders touch hot heating
elements. Do not use a towel or other bulky cloths
in place of a pot holder.
Never use your appliance
for warming or heating the
room,
Do not store flammable
materials near the
cooktop. Do not store or
use combustible materi-
als, gasoline or other
flammable vapors and
liquids in the vicinity of
this or any other appliance.
Keep the vent grille and the grease filters
clean to maintain good venting and to avoid
grease fires.
Do not let cooking grease or other flammable
materials accumulate on or near the cooktop.

o Never clean the cooktop surface when it is hot.
Some cleaners produce noxious fumes and wet
cloths could cause steam burns if used on a hot
surface.
oDo not use water on grease
fires. Never pick up a flaming
pan. Smother a flaming pan
on surface unit by covering
pan completely with well-fit-
ting lid, cookie sheet or flat
tray, or if available, use a dry
chemical or foam-type
extinguisher.
Flaming grease outside a pan can be put out by
covering with baking soda or, if available, a multi-
purpose dry chemical or foam type extinguisher.
o Do not heat unopened
food containers.
Pressure could buildup
and the container could
burst causing an injury,
o Do not touch heating elements. These surfaces
may be hot enough to burn even though they are
dark in color. During and after use, do not touch,
or let clothing or other flammable materials con-
tact the surface units or areas nearby surface
units; allow sufficient time for cooling, first.
Potentially hot surfaces include the cooktop,
removable modules, accessories and areas
facing the cooktop.
o When cooking pork, follow the directions exactly
and always cook the meat to an internal tempera-
ture of at least 170°F. This assures that,
in the remote possibility that trichina may be
present in the meat, it will by killed and the meat
will be safe to eat.
o Use proper pan size--the modules are equipped
with 2 surface units of different size. Select cook-
ware having flat bottoms large enough to cover
the surface unit heating element. The use of
undersized cookware will expose a portion of the
heating element to direct contact and may result
in ignition of clothing. Proper relationship of the
cookware to the heating element will also improve
efficiency.
Never leave the surface
units unattended at high
heat settings. Boilover
causes smoking and greasy
spillovers that may catch on
fire. 7
Be sure the drip pans are not covered and are
in place. Their absence during cooking could
damage cooktop parts and wiring.
Do not use aluminum foil to line the cooktop
tubs, the reflector pan, the grill or the griddle.
Misuse could result in a shock, fire hazard or
damage to the cooktop.
Only certain types of glass, glass/ceramic,
earthenware or other glazed containers are
suitable for cooktop service; others may break
because of the sudden change in temperature.
Only the grill grate and the griddle accessory
plate may be placed over the grill heating
element.
To minimize the possibility
of burns, ignition of
flammable materials, and
spillage, the cookware handles
should be turned toward the
center of the cooktop without
extending over nearby surface
units. i
Keep the tub, the reflector pan, the grill grate
and the grease collector jar clean. Be sure the
drain hole in the tub is open. If clogged, a fire can
occur. Empty the grease jars frequently.
Do not immerse or soak the removable
surface unit module, the solid disk module,
the radiant module or the grill heating
element. Do not put them in adishwasher.
Always turn the heating units to OFF before
removing cookware.

UMPORTAINTSAFET f 8NSTIRUCTSON$(co t oued)
oKeep an eye on foods being fried at HI or
Medium High heat settings.
o To avoid the possibility of a burn or electric
shock, always be certain that the controls for all
heating units are at the OFF position and all units
are cool before attempting to lift or remove them.
o Never leave the kitchen while using the grill or
griddle accessory.
oDo not replace the grease collector jar
with a mayonnaise jar whichcouldbreak
when hot grease drips into it. Replace with
any wide mouth canning jar.
Foods for frying should be as dry as possible.
Frost on frozen foods or moisture on fresh foods
can cause hot fat to bubble up and over sides of
pan.
oUse little fat for effective shallow or deep-fat
frying. Filling the pan too full of fat can cause
spillovers when food is added.
oIf a combination of oils or fats will be used in
frying, stir together before heating, or as fats melt
slowly.
o Always heat fat slowly, and watch as it heats.
o Never try to move a pan of hot fat, especially a
deep fat fryer. Wait until the fat is cool.
Use adeep fat thermometer whenever possi-
ble to prevent overheating fat beyond the smok-
ing point.
o To control flame-ups, turn down the heat setting
to LO rather than OFF. This keeps the downdraft
vent blower on. Or, turn the vent blower to ON,
then turn the grill OFE
Use a long-handled utensil to carefully remove
the food from the grill.
These steps should control the flame until it even-
tually goes out. if it does not, cover the entire grill
module with a cookie sheet or the lid from a large
roasting pan. Use a pot holder to remove this later
because it will be hot.
° NEVER USE WATER ON A GREASE FIRE.
