Step 8: 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 UP / DOWN
push-button once. 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 the UP / DOWN push-but-
ton 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
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
permanent 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
Installation Instructions to ensure that
nothing has been omitted or overlooked.
