Vent Fan

The vent fan has two metal reusable vent filters.
Models that recirculate air back into the room
also use a charcoal filter.
Reusable Vent Filters
The metal filters trap grease released by foods
on the cooktop. They also prevent flames from
foods on the cooktop from damaging the inside
of the oven.
Removing and Cleaning the Filters
To remove, slide them to the rear using the
tabs. Pull down and out.
To clean the vent filters, soak them and then
swish around in hot water and detergent. Don't
use ammonia or ammonia products because
they will darken the metal. Light brushing can
be used to remove embedded dirt.
For this reason, the filters must always be in
place when the hood is used. The vent filters
should be cleaned once a month, or as needed.
Rinse, shake and let dry before replacing.
To replace, slide the filters into the frame slots
on the back of each opening. Press up and to
the front to lock into place.
