Step 9 Verify Installation, Operation and
Cooktop Alignment
Before performing this procedure, verify that all packing
materials were removed from inside the snorkel and that the
grease filters and front panel have been properly installed.
Refer to the Care and Use Manual for instructions regarding
filter and front panel installation.
Plug the vent power cord into a proper electrical receptacle
and ensure that the circuit is energized.
A. Raise the snorkel to its fully extended position by
pressing the control button once (Figure 12). Do not
hold the push-button. The elevating motor will stop
when the snorkel reaches its full height. (Note: the
blower will not operate unless the snorkel is fully
raised).
B. Remove protective tape from top cap.
C. Turn the blower ON by selecting in turn each of the 3
speeds. Let the blower run several minutes at each
speed to evaluate its operation.
D. With the blower running, lower the snorkel to its fully
retracted position by pressing the control button once.
The blower will immediately turn off.
E. With the blower on HIGH, close the windows and doors
to the area to ensure that fan does not cause back
drafting in any outlet vent for another appliance.
F. Raise and lower the vent again, and check to make sure
that the top cap on the snorkel does not catch on the
back edge of the cooktop when it is lowered. If interfer-
ence occurs, adjust the position of the cooktop by
moving it against the front edge of the countertop
cutout, then re-secure the cooktop to the countertop.
Failure to eliminate interference may result in perma-
nent damage to the vent. Also, ensure that the vent
support legs have been properly secured to the cabinet
base using the screws provided.
If the vent system does not operate satisfactorily during any
of the above procedures, review all steps in these Installa-
tion Instructions to ensure that nothing has been omitted or
overlooked. Also, refer to the Care & Use Manual for addi-
tional information or call Bosch Customer Support 1-800-
994-2904.
