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 3recommended). 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 314x 10ductwork (can be  
transitioned to 6round). 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 314x 10″  
discharge facing DOWN. See the Changing  
Blower Direction section, if necessary.

1. Set the downdraft into the opening. Extend  
the leveling brackets to the floor of the cabinet  
so the downdraft sits straight. (NOTE: Leveling  
brackets can be removed and reattached in  
other positions. The bottom flange may have to  
face inward in tight cabinet installations.)  
2. Secure the downdraft to the countertop  
as follows: Hold the downdraft against the back  
of the countertop cut-out and tighten the 2  
mounting screws (one on each end of unit) on  
the underside of the countertop. Use a wood  
shim between the screw and the underside of  
granite countertops.  
1. Cut the hole in the cabinet as well as holes  
in the wall or floor as necessary.  
2. Mount the roof or wall cap and work back  
toward the cabinet, attaching all ductwork,  
elbows and transitions as previously planned.  
Tape all ductwork connections to make them  
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 314x 10collar 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.
