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.
Care and cleaning of the downdraft system.
Grease filters
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.

IMPORTANT: These vents are recommended for island installations. Against-the-wall installations are
limited due to countertop depth requirements. The vent and cooktop combined depth requires an extra
deep flat countertop surface.
■ The countertop must be at least 26″ deep with a
flat surface area of 231⁄2″ or more, front to back
(NOTE: JGP932S requires 233⁄4″ flat surface area
and JP350SC, JP930SC and JP938SC require 235⁄8″
flat surface area).
In addition, other clearances to the front edge of
the countertop must be considered.
