Recirculating Kit (Optional)
When used in recirculation mode, to reduce the risk of
Fire and Shock, use only conversion kit Model
HVREC5UC.
If it is not possible to vent cooking fumes and vapors to
the outside, the hood can be used in the non-vented
(recirculating) mode, using the recirculating kit. Fumes
and vapors are recycled through the round grid.
