THE PROFESSIONAL DOWNDRAFT Installation Guide MODELS: DD-36SS DD-30SS A MESSAGE TO OUR CUSTOMERS Thank you for selecting this DCS Downdraft Vent System. Because of its unique features, we have developed this Installation Guide. It contains valuable information on how to properly install your new Downdraft Vent System for years of safe and enjoyable cooking. For your convenience, product questions can be answered by a DCS Customer Care Representative by phone: 1-888-281-5698, email: support@dcsappliances.com or by mail: Fisher & Paykel Appliances, Inc. Attention: DCS Customer Care 5900 Skylab Road, Huntington Beach, CA 92647 WARNING TO REDUCE THE RISK OF A COOKTOP GREASE FIRE: Never leave surface units unattended at high settings. Boilovers cause smoking and greasy spillovers that may ignite. Heat oils slowly on low or medium setting. Always turn the Downdraft "ON" when cooking at high heat or when cooking flaming foods. Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or filter. Use proper pan size. Always use cookware appropriate for the size of the surface element. WARNING TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A COOKTOP GREASE FIRE, OBSERVE THE FOLLOWING: SMOTHER FLAMES with a closefitting lid, cookie sheet, or metal tray, then turn off the burner. BE CAREFUL TO PREVENT BURNS. If the flames do not go out immediately EVACUATE AND CALL THE FIRE DEPARTMENT. NEVER PICK UP A FLAMING PAN - You may be burned. DO NOT USE WATER, including wet dishcloths or towels - a violent steam explosion will result. Use an extinguisher ONLY if: 1. You know you have a Class ABC extinguisher, and you already know how to operate it. 2. The fire is small and contained in the area where it started. 3. The fire department is being called. 4. You can fight the fire with your back to an exit.

Consult the cooktop installation instructions given by the manufacturer before making any cutouts. MOBILE HOME INSTALLATION - The installation of this Downdraft must conform to the Manufactured Home Construction and Safety Standards, Title 24 CFR, Part 3280 (formerly Federal Standard for Mobile Home Construction and Safety, Title 24, HUD, Part 280). Four wire power supply must be used and the appliance wiring must be revised. See Electrical Requirements (page 4). Venting system MUST terminate outside the home. DO NOT terminate the ductwork in an attic or other enclosed space. DO NOT use 4" laundry-type wall caps. Flexible-type ductwork is not recommended. DO NOT obstruct the flow of combustion and ventilation air. Failure to follow venting requirements may result in a fire. Electrical ground is required on this downdraft ventilation system. If cold water pipe is interrupted by plastic, non-metallic gaskets or other materials, DO NOT use for grounding. DO NOT ground to a gas pipe. DO NOT have a fuse in the neutral or grounding circuit. A fuse in the neutral or grounding circuit could result in electrical shock. Check with a qualified electrician if you are in doubt as to whether the downdraft is properly grounded. Failure to follow electrical requirements may result in a fire. WARNING: TO REDUCE THE RISK OF FIRE, ELECTRICAL SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING: Use this unit only in the manner intended by the manufacturer. If you have any questions, contact the manufacturer. Before servicing or cleaning unit, switch power off at service panel and lock the service disconnecting means to prevent power from being switched on accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag, to the service panel. Installation Work And Electrical Wiring Must Be Done By Qualified Person(s) In Accordance With All Applicable Codes And Standards, Including Fire-Rated Construction. Sufficient air is needed for proper combustion and exhausting of gases from fuel burning equipment through the flue (chimney) to prevent backdrafting. Follow the heating equipment manufacturer's guideline and safety standards such as those published by the National Fire Protection Association (NFPA), and the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities. Ducted fans must always be vented to the outdoors. 3 PLANNING THE INSTALLATION VENTING REQUIREMENTS Determine which venting method is best for your application. Ductwork can extend either through the wall or the roof. The length of the ductwork and the number of elbows should be kept to a minimum to provide efficient performance. The size of the ductwork should be uniform. Do not install two elbows together. Use duct tape to seal all joints in the ductwork system. Use caulking to seal exterior wall or floor opening around the cap. Flexible ductwork is not recommended. If it is used, each foot of flexible ductwork used is equivalent to two feet of straight metal ductwork when calculating the duct run length. Thus, a flexible elbow equals two standard elbows. Make sure there is proper clearance within the wall or floor for exhaust duct before making cutouts. Do not cut a joist or stud unless absolutely necessary. If a joist or stud must be cut, then a supporting frame must be constructed. WARNING: To Reduce The Risk Of Fire, Use Only Metal Ductwork. ELECTRICAL REQUIREMENTS A 120 volt, 60 Hz AC-only electrical supply is required on a separate 15 amp circuit, fused on both sides of the line. A time-delay fuse or circuit breaker is recommended. The fuse must be sized per local codes in accordance with the electrical rating of this unit as specified on the serial/rating plate located inside the unit near the field wiring compartment. THIS UNIT MUST BE CONNECTED WITH COPPER WIRE ONLY. Wire sizes must conform to the requirements of the National Electrical Code, ANSI/NFPA 70 -latest edition, and all local codes and ordinances. Wire size and connections must conform with the rating of the appliance. Copies of the standard listed above can be obtained from: National Fire Protection Association Battery March Park Quincy, Massachusetts 02269 This appliance should be connected directly to the fuse disconnect (or circuit breaker) through flexible, armored or non-metallic sheathed copper cable. Allow some slack in the cable so the appliance can be moved if servicing is ever necessary. A UL Listed, 1/2" conduit connector must be provided at each end of the power supply cable (at the appliance and at the junction box). When making the electrical connection, cut a 1-1/4" hole in the wall. A hole cut through wood must be sanded until smooth. A hole through metal must have a grommet. NOTE: SUITABLE FOR USE WITH SOLID STATE SPEED CONTROLS. CAUTION: For General Ventilating Use Only. Do Not Use To Exhaust Hazardous or Explosive Materials and Vapors. 4 SPECIFICATIONS 30" or 36" 8-1/4" 1-1/2" 27" for 30" model 33" for 36" model 16" 3-1/4" x 10" 26-1/8" 16" 9-3/8" 2-1/8" Fig. 01 Downdraft Dimensions 4-1/8" + 1/2 " min. 23-9/16" 17-9/16" 17-3/16" 3-1/4" 3/8" 3/8" 10" 4-1/8" + 1/2" min. 4-1/8" + 1/2" min.

Fig. 03 illustrates venting options. Fig. 02 shows the ductwork cutout dimensions. CALCULATE THE DUCT RUN LENGTH The ductwork length should not exceed 35 equivalent feet for 3-1/4" X 10" duct, or 60 equivalent feet for 9" FIG.03 Ducting round duct. Calculate the length of the ductwork by adding the equivalent feet listed in Fig. 04 for each piece of duct in the complete system. An example is given in Fig. 05. For best results, use no more than three 90° elbows. Make sure that there is a minimum of 24" of straight duct between elbows if more than one is used. Do not install two elbows together. Round duct is recommended instead of rectangular duct especially if elbows are needed. Rectangular duct should transition to round as soon as possible (6" round minimum).

Fig. 06 shows the cutout dimensions for DCS CT-365 and CT-304 and for all other cooktops see Fig. 06a (page 8). Fig. 07 shows the tolerances between the cooktop and the downdraft. These tolerances must be observed for proper installation. WARNING: When planning the cutout for the downdraft: Draw both the cooktop and downdraft cutouts on the countertop before making any cuts. Check that there is enough room in the cabinet for both. Failure to follow these warnings could result in damage to the countertop. WARNING: These tolerances must be observed!
