Planning the Installation General System Layout The vent system consists of the downdraft vent and a Dacor-approved cabinet blower (MRV3015 and MRV3615), remote blower, or in-line blower. (See Pg. 7). WARNING • Failure to install an approved blower and proper duct- ing will cause a backdraft and poor venting. • To reduce risk of personal injury from reaching over a hot appliance, avoid cabinet storage directly above the cooking surface. • Follow minimum clearances and installation location in the vent, appliance, and blower instructions. Failure to do so may cause a fire or safety hazard. • Plan the installation so minimum dimensions are met or exceeded. All contact surfaces between the downdraft vent and cabinets/walls must be solid and at right angles. • The downdraft vent has adjustable anchor legs to accom- modate various cabinet heights. • Install the downdraft vent and range/cooktop so they can be removed for service. • Allow access from the cabinet front to the chassis, and utilities of the downdraft vent and cooktop for inspection and service. (Drawers/shelves must be removable.) • There are 7/8” access holes in the bottom and side of the downdraft vent for connecting blower wiring and strain relief. Wire the blower to turn on when the downdraft vent is turned on. When installing a remote or in-line blower, run the blower wiring/conduit parallel to the duct work, connecting it to the downdraft vent on one end and the blower on the other. • Allow room for the exhaust duct coming out of the unit. (See Planning the Duct Work, Pg. 8, for details.) • Consider the maximum-allowable duct run when decid- ing the layout. (See Planning the Duct Work, Pg. 8, for details.) • See the range/cooktop installation instructions for mini- mum cutout dimensions specific to the downdraft vent being installed.

(See Pg. 9.) • To reduce risk of fire and to properly exhaust air, duct air outdoors, not into any interior spaces or garages. • TO REDUCE FIRE RISK, USE ONLY METAL DUCTING. • DO NOT install multiple blowers to lengthen the duct run. Even small differences between blower airflow rates can greatly reduce the downdraft vent’s air draw. • When installing an ILHSF blower, minimize noise by installing it as close as possible to the duct-system exhaust. (Minimum recommended distance from the downdraft vent is 5 feet.) • When connecting the duct work to the back of the unit, the customer must supply a 31⁄4 x 10 rectangular transi- tion to make the connection.

The Equivalent Number of Feet for each elbow and transition must be subtracted from the maximum straight length to compensate for wind resistance. To decide the maximum allowable length of the ducting, subtract all equivalent lengths of the elbows and transitions listed below from the Blower Maximum Duct Straight Length. Example: For a downdraft vent system using a 31⁄4 x 10 rectangular duct, two (2) 31⁄4 x 10 90° elbows, a 31⁄4 x 10” rectangular to 10” round transition, and a REMP16 remote blower: • From the Blower Maximum Duct Straight Length table, the max length without transitions and elbows is 60 ft. • The equivalent length of each 90° elbow is 15 ft. • The equivalent length of 45° elbow is 2 ft. • The equivalent length of the transition is 4 ft. • The total equivalent length of the above parts is: 15 ft + 15 ft + 4 ft + 2 ft = 36 ft. • The max amount of straight duct that can be used with a REMP16 and the above parts is: 60 ft – 34 ft = 24 ft.

For equivalent length, contact the manufacturer or a qualified HVAC specialist; **Not applicable to REMP blowers. Duct Work Design Tips • Reduce transitions and turns to the fewest sharp angles. Two staggered 45° angles are better than one 90°. Keep turns as far from the hood exhaust as possible, with the most possible space between each bend. • For best performance, use round ducting when possible, especially when elbows are required. • If multiple elbows are used, try to keep a minimum of 24” of straight duct between them. Avoid “S” or “back to back” configurations of adjacent elbows. • Do not use flexible metal ducting.

Kit includes adapter, wiring diagram label (PN 106770), 3 wing nuts (PN 83035), 3 flat washers (PN 83008) and 6 lock washers (PN83340). WARNING Bottom knock-out • If the electrical outlet does not meet the Electrical Specifications on Pg. 2, postpone the installation until a licensed electrician install the proper outlet. • Install the vent vertically only. • Do not enlarge or modify the exhaust knock-outs. Cut an exhaust hole on the chassis only as shown to pre- vent an increase in noise and compromised function. NOTE: The downdraft vent installs in the back of the cut- out, separate from the range or cooktop. Install the down- draft vent before installing the range or cooktop. 2. Start by loosely attaching the anchoring legs to the studs on the left and right sides of the downdraft vent using the provided Keps nuts and washers. Put nuts/ washers on studs 12Installation Preparation: Downdraft Vent With ILHSF-/REMP-Series Blower NOTE: For units using the CABP3 cabinet blower, skip to Installation Preparation for Downdraft Vent with CABP3 Cabinet Blower, on facing page. 1. Remove the appropriate side or bottom exhaust knockout (depending on the desired exhaust configu- ration) from the downdraft vent chassis by cutting the metal cross overs and removing the insert. 2. Cut and remove the foil material inside the knock-out hole or the vent will not work. • If the unit will vent through the bottom or side, install the suppled 15/8 x 16 to 31⁄4 x 10 transition to the exhaust location. Before installing, peel the protective backing off the foam tape, and apply it to the transition flanges. Attach the transition with the provided sheet metal screws (see below). • If the unit will vent through the back, attach a 3 1⁄4 x 10 duct to the vent hole created by removing the knock-out on the back of the unit. 3.

(See the user manual about filter installation.) CAUTION Before plug-in, route the downdraft-vent power cord away from range or cooktop surfaces. 1. Ensure the power switch atop the downdraft vent is in the up position. 2. Plug in the downdraft vent. 3. Press the power switch to raise the vent. 4. Once raised, the vent should begin to draw air. Turn the variable-speed control switch in both directions to verify that the system operates correctly. 5. Press the top cap up/down switch to lower the vent. 6. Ensure the vent top cap does not catch on the back edge of the cooktop/range. If it does catch, reposition the cooktop/range to avoid permanent vent damage. If the downdraft vent is not functional after installation: • Ensure power is supplied to the downdraft vent. • Ensure the downdraft vent supplies power to the blower. • If the vent will not raise properly or makes a scraping sound, check for under-counter obstructions. If the downdraft vent fails to function after performing the above checks, do not try to repair it yourself. Contact Dacor Customer Assurance: 833-353-5483.
