A:AnswerHi Gils, thank you for your question and interest in Model:DUH30252UC. If the model is not vented to the outside, the air will be recirculated through disposable charcoal filters that help remove smoke and odors. The charcoal filters cannot be cleaned. They must be replaced.
The charcoal filters are clipped inside of each metal grease filter (mounting instructions included with charcoal filters kit). The charcoal filters should be replaced when they are noticeably dirty or
discolored (usually after 6–12 months, depending on hood usage). This has washable aluminium, dishwasher-safe mesh filters.
A:AnswerHi there. Thank you for your question. For a vertical or horizontal discharge you can use a rectangular duct that is 3 1/4” x 10”. For a vertical discharge you may also use a round 7” duct.
A:AnswerHi Dave, thank you for your question and interest in Model:DUH30252UC. Per the Installation Instructions: For Recirculating: Use the hood as a template and mark the locations on the cabinet for the electrical wiring and keyhole screw slots. Since the hood is to be recirculated (not to be
vented outside), do not cut out any vent openings in the wall or cabinet bottom. To recirculate air into the kitchen, make sure the plastic vent lever is in the VERTICAL position (flat against the plastic blower housing).
