SERVICING
NOTE: BE SURE ELECTRICAL POWER IS
Disconnect power to the cooktop and remove it first.
Reverse the steps in the Install the Downdraft section
to remove the downdraft from the cabinet.
OFF BEFORE SERVICING THE UNIT.
It may be necessary to remove the downdraft blower
system from the cabinet in order to service components
such as the blower motor or air vent mechanism.
Service parts are available from your local GE
distributor or from a GE Service and Parts Center.
USING YOUR DOWNDRAFT VENT SYSTEM
Controls
Turn the downdraft blower
ON by pressing down on
the activating switch. The
air vent will rise.
Turn the downdraft
blower OFF by pressing
the activating switch
again. The air vent will
go down and the blower
will shut off.
The blower can be ON or
OFF and its speed can be
adjusted with the recessed
knob on the right side of
the air vent.
NOTE: For most convenient operation, set the
blower to your favorite speed. The blower will come
on to this speed whenever the activating switch is
pressed and the air vent rises.
Knob
CAUTION: Be careful when raising or lowering
the downdraft. Be sure pots, pot handles and other
objects are clear of the downdraft cover and cannot
be struck or tipped by the downdraft being raised.
• To avoid injury, make sure there are no fingers
around the downdraft cover when it is lowered.
• Keep hands and fingers away from all
downdraft parts.
COOKING TIPS
• The high-capacity performance 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 on to high
right away. Adjust the fan speed for best cooking
results.
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.
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.
Use of the blower at a 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.
• The downdraft may not completely capture all the
steam from pans on the front burners.

CARE AND CLEANING
Grease Filter
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: Pull the filters out by grasping them and
pulling straight up.
To clean: Soak and then agitate in a hot detergent
solution. Light brushing may be used to remove
embedded soil. Rinse, shake and remove moisture
before replacing.
NOTE: The filters are different sizes. Be sure to
With careful handling, the filter will last for years.
If replacement becomes necessary, order the part
from your dealer.
replace them with the longer filter on the left.
When replacing the filters, the long one goes in the
left side.
Blower
Painted or Metal Surfaces
1. DISCONNECT THE DOWNDRAFT
POWER SUPPLY BY REMOVING THE
POWER CORD FROM THE RECEPTACLE.
Clean greasy surfaces frequently, using a mild
detergent. Do not use abrasive cloth, steel wool
pads or scouring powder because they will mar
the surface.
2. Remove the blower cover.
3. Use a vacuum hose to clean the blower.
Do not immerse the blower in water.
Stainless Steel Surfaces (on some models)
Do not use a steel wool pad; it will scratch the
surface.
4. Replace the blower cover.
5. Reconnect the power supply.
To clean the stainless steel surface, use warm, sudsy
water, a stainless steel cleaner such as Kleen King®,
or an all-purpose liquid or spray cleaner. Always
scrub in the direction of the grain. Rinse thoroughly
with a sponge or cloth and clean water. Dry with a
soft, clean cloth. After cleaning, use a stainless steel
polish, such as Stainless Steel Magic®, Revere
Copper and Stainless Steel Cleaner® or Wenol All
Purpose Metal Polish®. Follow the product
instructions for cleaning the stainless steel surface.

Plan the Ductwork
Steps to Determine Flexible Ducting’s
Equivalent Length
1. Measure the actual amount of offset
(Maximum 3″ recommended). The effect upon
Right
discharge
airflow is dependent upon the amount of offset.
2. Calculate the equivalent ducting allowances
using:
Left discharge
( ___ in. offset) x (14 Ft. per inch)
= ___ Ft. equivalent length.
Down discharge
(as shipped)
3. Ensure that the total equivalent length of
ducting does not exceed the maximum
recommendation of 100 feet.
1. This downdraft blower system is designed
for use with 31⁄4″ 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.
Venting Island to Outside Wall
Wall
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
joists, wall studs, electrical wiring or plumbing
for possible interference.
NOTE: The unit is shipped with the 31⁄4″ x 10″
discharge facing DOWN. See the Changing

secure and air tight.
3. Connect the ductwork (and transition,
if required) to the downdraft. If necessary,
LOOSEN wing nuts and screws that hold the
blower in place, and slide the blower left or right
to meet the ductwork. Retighten the screws and
wing nuts.
3. Screw the leveling brackets to the bottom of
the cabinet. Tighten the screws holding the
leveling bracket to the unit on each side.
NOTE: A 31⁄4″ x 10″ collar is provided for
installers who prefer to rivet the cutwork to the
unit. This will allow the blower to be removed
and replaced easily in service situations without
disturbing the ductwork.
Install the Electrical Wiring
1. Mount a standard wiring box, with
3-pronged outlet, inside the cabinet. Make sure
the downdraft’s power cord can easily reach it.
2. Run the appropriate power cable into the
cabinet and connect it to the outlet.
3. Plug the downdraft’s power cord into
the outlet.

Install the Cooktop
Adjust the Switch
• With the Downdraft in the “Down” position,
place the cooktop into the cutout.
The downdraft is factory-adjusted for proper
operation. However, shipping and handling may
affect the positions of the activating switch.
• Push the cooktop back until the back edge of
the cooktop just barely touches the front edge of
the downdraft cover.
To adjust position of activating switch:
WARNING: To avoid possible electrical
shock, personal injury or death—
disconnect electrical power.
• Using a dime as a thickness gauge, align the
cooktop so that there is a minimum uniform gap
of 0.05″ (the thickness of a dime) between the
cooktop and the downdraft cover.
NOTE: Do not force the downdraft cover to
move rearward when aligning the cooktop. This
may cause the downdraft cover to impact and
damage the cooktop when the vent is raised and
lowered.
1. If the downdraft is plugged into the electrical
outlet, unplug it.
2. Lift the air vent straight up and cock it
slightly so it remains in the UP position.
