RAISE/LOWER Switch (30” models only)
Turn the downdraft blower ON by pressing
the RAISE/LOWER switch located at the top
right of the vent (on some models). Place
your finger on the “center” of the switch
and hold until you observe the vent moving,
then release. The air vent will rise. Use the
selector switch to turn the blower ON, OFF
or to change the blower speed.
The vent may be lowered by again pressing
the RAISE/LOWER switch at the top right side
of the vent. The blower, if left on, will
automatically go off when the vent is
lowered.
NOTE: For most convenient operation, set the
blower to the speed you use most often. The
blower will come on to this speed whenever
the unit is raised.
Remote RAISE/LOWER switch
(36″models only)
36″models have a remote RAISE/LOWER
switch. It operates in the same manner as
the switch located on the vent.
RAISE/LOWER switch location may vary.
Using the Cooktop
Caution
Be careful when raising or lowering the
downdraft. Be sure pots, pot handles and
other objects are clear of the downdraft and
cannot be struck or tipped by the downdraft
being raised.
NOTE: There is a slight trim overhang at each
end of the vent.
■ To avoid injury, be sure fingers are clear
of the downdraft cover when it is being
lowered.
■ Keep hands and fingers away from all
downdraft parts.

The efficiency of your downdraft depends on
a clean filter.
Frequency of cleaning depends on the type
of cooking you do. Grease filters should be
cleaned at least once a month.
Never operate the downdraft without the filters
in place.
To remove: Lift up and pull the bottom out.
Remove the left filter first, then slide the
right filter to the left and remove it.
To clean: Soak and then agitate in a hot
detergent solution. Light brushing may be
used to remove imbedded soil. Rinse, shake
and remove moisture before replacing.
Filters may be cleaned by placing in
dishwasher, although some slight color
fading may occur after several washings.
With careful handling, the filter will last for
years. If replacement becomes necessary,
order the part from your dealer.
Cooking Tips
The high air movement of this downdraft
system can increase the cooking times for
some foods. It may take longer to reach
high cooking temperatures if the downdraft
is turned to high right away. Adjust the fan
speed for best cooking results.
For best results when heating oil for deep
frying or when boiling water, use the front
surface units or wait until the water is
boiling or the oil is at frying temperatures
before turning on the downdraft.
The downdraft may not completely capture all the
steam from pans on the front burners.
Canning
When canning foods in a water-bath canner,
a gentle but steady boil must be maintained
continuously for the required time.
When canning foods in a pressure canner,
the pressure must be maintained
continuously for the required time.
Use of the blower at HIGH speed when
canning may reduce the temperature
enough to stop boiling. While canning,
we recommend using the downdraft at
LOW speed and using the front surface unit.
Painted or metal surfaces
Grease filters
Clean greasy surfaces frequently, using a
mild detergent.
Do not use abrasive cloth or cleaners, steel wool
pads or scouring powder because they will scratch
the surface.

Installation of the downdraft system.
Read these instructions completely and carefully.
Planning the Ductwork
This downdraft blower system is designed
for use with 31⁄4″x 10″ductwork (can be
transitioned to 6″round). Two different
discharge directions are available with side-to-
side adjustment for accurate alignment of
ductwork.
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 joists, wall studs, electrical wiring or
plumbing for possible interference.
Steps to Determine Flexible Ducting’s Equivalent Length
Measure the actual amount of offset
(Maximum 3″recommended). The effect
upon airflow is dependent upon the amount
of offset.
Calculate the equivalent ducting
allowances using:
( ___ in. offset) x (14 ft. per inch)
= ___ ft. equivalent length.
Ensure that the total equivalent length of
ducting does not exceed the maximum
recommendation of 150 feet.
