BEFORE YOU BEGIN6Installation Range HoodInstructionsRead these instructions completely and carefully.• IMPORTANT – Save theseinstructions for local inspector’s use.• IMPORTANT – Observe allgoverning codes and ordinances.• Note to Installer – Be sure to leave theseinstructions with the Consumer.• Note to Consumer – Keep these instructionsfor future reference.• Skill level – Installation of this appliance requiresbasic mechanical and electrical skills.• Completion time – 30 minutes–3 hours• Proper installation is the responsibility of theinstaller.• Product failure due to improper installation is notcovered under the Warranty.NOTE: Read the ductwork sections only if you do nothave existing ductwork. If you have existing ductwork,skip to the “Damage” section and proceed.The venting system must exhaust to the outside.This hood can be vented vertically through uppercabinets or horizontally through an outside wall.Ductwork is not included.Exhaust connection:The hood exhaust has been designed to mate withstandard 31⁄4″ x 10″ rectangular ducting or 7″ diameterround ducting.If a 6″ round duct is required, a rectangular-to-roundtransition adaptor must be used*. Do not use less thana 6″ diameter duct.Maximum duct length:For satisfactory air movement, the total duct lengthof a 31⁄4″ x 10″ rectangular, 6″ or 7″ diameter roundduct should not exceed 65 equivalent feet. See theWORKSHEET–CALCULATE TOTAL EQUIVALENTDUCTWORK LENGTH section.NOTE: It is important that ducting be installed usingthe most direct route and with as few elbows as possible.This ensures clear venting of exhaust and helps preventblockages. Also, make sure dampers swing freely andnothing is blocking the ducts.Elbows, transitions, wall and roofcaps, etc.,present additional resistance to airflow and areequivalent to a section of straight duct longer than theiractual physical size. When calculating the total ductlength, add the equivalent lengths of all transitions andadaptors plus the length of all straight duct sections. Thecharts on the following pages show you how to calculatetotal equivalent ductwork length using the approximatefeet of equivalent length of some typical ducts.* IMPORTANT: If a rectangular-to-round transition adaptor is used, thebottom corners of the damper willhave to be cut to fit, using the tinsnips, in order to allow freemovement of the damper.Equivalent lengths of duct piecesare based on actual tests and reflectrequirements for good ventingperformance with any hood.DUCTWORK REQUIREMENTSWARNING – Before beginning theinstallation, switch power off at service panel and lockthe service disconnecting means to prevent powerfrom being switched on accidentally. When the servicedisconnecting means cannot be locked, securelyfasten a prominent warning device, such as a tag,to the service panel.FOR YOUR SAFETY:Questions?
