3 Installation Specifications
Planning the Location warning • Observe all governing codes and ordinances during planning and installation. Contact your local building department for further information. • The range hood is heavy. To prevent personal injury and property damage caused by the hood coming loose from the ceiling, use only the hood mounting bracket provided with the unit. ■ Carefully check the location where the hood is to be installed. The hood should be placed for convenient access. Make certain that electrical power can be provided in the selected location. ■ The hood model selected must be as wide as the cooktop surface or wider. ■ Install the range hood and cooking appliance(s) so that they can be removed if service is required. ■ Plan the installation so that all minimum dimensions are met or exceeded (see page 3). Dimensions shown provide minimum clearances, unless other wise noted. ■ The mounting bracket must be attached directly to the studs in the ceiling, or to a reinforced mounting block secured to the studs. See below for mounting bracket hole dimensions. 12 9/16” (31.9 cm) 6 1/8” (15.6 cm) 11” (27.9 cm) Dia. Back Dimensions ■ The mounting bracket must be mounted directly above the center of the cooking surface. The mount ing surface must be level. ■ Allow clearance in the center of the mounting bracket for the exhaust duct to pass through the ceiling. Planning the Duct Work warning • To prevent combustion by-products, smoke or odors from entering the home and to improve efficiency, tape all duct joints securely. • Use only duct work deemed acceptable by state, municipal and local codes. • DO NOT install an additional in-line or external blower to increase the length of the duct run. Even small differences between blower air flow rates can greatly reduce the air draw of the hood. CAUTION To reduce the risk of fire and to properly exhaust air, be sure to duct air outside the house or building. Do not vent exhaust air into spaces within walls or ceilings or into attics, crawl spaces or garages. ■ All duct work materials (including screws and duct tape) must be purchased separately by the customer. ■ When planning new duct work, always look for the shortest, most direct route to the outside. ■ The hood exhaust connects to an 8-inch round duct. You can increase the duct size over the duct run if desired. To prevent a back draft, never decrease the duct size over the run. If existing duct work is smaller than 8 inches in diameter, remove it and replace it with 8-inch duct work. ■ Do not rely on tape alone to seal duct joints. Fasten all connections with sheet metal screws and tape all joints with certified silver tape or duct tape. Use sheet metal screws as required to support the duct weight. ■ To prevent back-drafts, a damper at the duct outlet may also be required. ■ Make sure duct work does not interfere with floor joists or wall studs.

Calculating the Maximum Duct Run Length The maximum straight duct length for the hood is 50 feet. To determine the actual maximum duct run, subtract the equivalent length of each elbow, transition and cap from 50 feet. EQUIVALENT LENGTHS Piece Subtract Piece Subtract 8” 90° elbow 7 feet 10” 90° elbow 5 feet 8” 45° elbow 3 feet 10” 45° elbow 2 feet Duct Work Design Tips Wherever possible, reduce the number of transitions and turns to as few sharp angles as possible. Two staggered 45° angles are better than one 90°. Keep turns as far away from the hood exhaust as pos sible, and as much space between bends as possible. For best performance, use round duct instead of rectan gular, especially when elbows are required. If multiple elbows are used, try to keep a minimum of 24 inches straight duct between them. Avoid “S” or “back to back” use of adjacent elbows.
3¼” X 10” to round 90° transition 25 feet 3¼” X 10” to 8”/10” round transition 4 feet In regions where the weather gets extremely cold, use thermal breaks, such as a short section of non-metallic duct, to avoid indoor heat loss. Locate the break as close

5 Installation Instructions
warning • Observe all governing codes and ordinances during installation. Contact your local building department for further information. • A qualified technician must complete the installation of this built-in appliance. The owner is responsible to make sure the hood is properly installed. • Do not install the range hood unless the power supply provided meets the required Electrical Specifications (see page 3). • To avoid an electric shock hazard and property damage, locate electric wires and water pipes and avoid drilling or cutting in the vicinity. • The range hood is heavy. To prevent personal injury and property damage install the hood only as specified in the following instructions. Make sure all screws used to mount and assemble the hood are tight. Failure to properly anchor the hood to the ceil ing may result in personal injury due to the unit fall ing. Hanging the range hood requires two people. Do not attempt to lift the hood without assistance. • DO NOT use the mounting anchors provided with the unit. They are part of a standard mounting hard ware package provided with many Dacor hoods, but not suitable for use with this model. Install Mounting Bracket 1. Locate the mounting bracket and position it against the ceiling at the previously determined mounting location (see page 4). 2. Using a pencil, mark the four mounting hole locations on the ceiling. 3. Drill four 1/16” (1.6 mm) pilot holes at the mounting hole locations. 4. Attach the bracket using four #12 screws (not sup plied). Make sure the screws penetrate into the wood mounting surfaces 1 1/2” (3.8 cm). 5. Cut a hole for the duct to pass through in the center of the bracket. Assemble the Hood 1. Place the hood assembly on a soft surface with the bottom side down during assembly to avoid damage. 2. Tip the hood up on it’s side and remove the filter(s) to reduce weight and avoid damage. 3. Inside the exhaust outlet(s) there are metal or plastic damper flaps. The flaps close to help prevent back drafts when the blower is turned off. Make sure all the flaps open and close freely before proceeding. Remove any shipping tape that may be present. 4. Remove the tape that holds the wiring in place on top of the hood during shipment. 5. On models with two blowers, put the exhaust cowling over the blower outlets on the top of the hood. Fasten the cowling in place with 14 machine screws.
6 Installation Instructions 6. Separate the bottom framework piece from the top framework piece. The top frame work piece has 5-inch slots on the sides. The bottom piece has a series of holes on the sides.
7. Position the bottom framework piece on top of the hood. Slide the studs on the top of the hood into the holes on the bottom of the framework piece. The cut outs for the wiring allow the bottom framework piece to fit on only one way. If it does not fit properly, turn it 180° so that the cut-outs line up. Make sure all wir ing is tucked inside the framework piece and are not pinched. 8. Use eight provided lock washers and nuts to secure the bottom framework piece to the top of the hood. 9. Determine the required framework height. To deter mine the required framework height: • Measure the distance from the ceiling to the cooking surface. • Subtract the height at which the hood will be mounted (30” minimum) and the hood thickness (12 1/2”) from the distance measured. 10. Put the top framework piece over the bottom frame work piece. The mounting slots on the top piece must be up. 11. Use four machine screws to fasten the top piece to the bottom piece. The total height of the two pieces together must equal the required framework height determined above. 12. Remove the protective plastic covering from both pieces of the chimney assembly. Do not remove the protective tape strips from the inside. They protect the telescoping pieces from scratching during instal lation. 13. Carefully slide both sections together so that only the vents on the top section show. 14. Hold the chimney vertically with the vents up. 15. Carefully put the chimney over the top of the frame work, taking care not to scratch the surfaces. Make sure the Dacor logo faces the same side as the con trol panel. 16. Make sure any wires are tucked in behind the chim ney and are not pinched. Framework bottom Hood Chimney Top framework Bottom framework Hood Mounting slots
