Step 8: Verify Installation, Operation
and Cooktop Alignment
Y Before performing this procedure, verify
that all packing materials were removed
from inside the snorkel and that the grea-
se filters and front panel have been pro-
perly installed. Refer to the Care and Use
Manual for instructions regarding filter
and front panel installation.
Y Plug the vent power cord into a proper
electrical receptacle and ensure that the
circuit is energized.
Y A. Raise the snorkel to its fully extended
position by pressing the UP/DOWN

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).
Y B. Remove protective tape from top cap.
Y C. Turn the blower ON by selecting in
turn each of the 3 speeds. Let the blo-
wer run several minutes at each speed to
evaluate its operation.

Step 8: Verify Installation, Operation
and Cooktop Alignment
Y 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.
Y 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
interference occurs, adjust the position
of the cooktop by moving it against the
front edge of the countertop. Failure to
eliminate interference may result in per-
manent damage to the vent. Also, ensu-
re 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 proce-
dures, review all steps in these Installation
Instructions to ensure that nothing has been
omitted or overlooked. Also, refer to the
Care & Use Manual for additional informati-
on or call Thermador Customer Support 1-
