Vent unit to outside of building, only. • On avarage 2 hours are necessary to complete installation (without considering cut to be done on wall and or on cabinet, installation of ducts , conduit and electrical connections to the mains). • The hood is fitted with Screws and Drywall Anchors suitable for most surfaces, consult a Qualified Installer, check if they perfectly fit with your cabinet/wall. • Do not use flex ducting. • COLD WEATHER installations should have an additional backdraft damper installed to minimize backward cold air flow and a nonmetallic thermal break to minimize conduction of outside temperatures as part of the ductwork. The damper should be on the cold air side of the thermal break. The break should be as close as possible to where the ducting enters the heated portion of the house. • Remote blowers require a five wire installation. • Make up air: Local building codes may require the use of Make-Up Air Systems when using Ducted Ventilation Systems greater than specified CFM of air movement. The specified CFM varies from locale to locale. Consult your HVAC professional for specific requirements in your area. • Typical installation Min installation height from the range top to the bottom of the hood is 30" if a gas range is used or 24" to 30" if an electric range is used.
