Document # PG08-003 Planning the Duct Work RV30, RV36, RV46 30", 36", 46" Wide, Raised Vent Revised 03/29/10 Page 5/7 PLANNING GUIDE WARNING • 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. • Tape all duct joints securely to prevent combustion by-products, smoke or odors from entering the home. Doing so will also improve system efficiency. • For proper operation this unit must be installed with a remote blower or internal cabinet blower. Use only one of the models specified. • TO REDUCE THE RISK OF FIRE, USE ONLY METAL DUCT WORK. • DO NOT install more than one blower. Even small differences between blower air flow rates can greatly reduce the air draw by the raised vent. You must install one of the Dacor blower models listed below for proper operation. For models REMP3 or REMP16, see the REMP3/16 Remote Blower Installation Instructions. For model CABP3, see the instructions later in this manual. Only one blower shall be installed. BLOWER RATINGS FOR DACOR BLOWERS APPROVED FOR USE WITH RV SERIES RAISED VENTS Model Number Rating CABP3 (cabinet) 600 CFM* ILHSF8 (in-line) 600 CFM** ILHSF10 (in-line) 1100 CFM** REMP3 (remote) 600 CFM** REMP16 (remote) 1000 CFM** * Nominal rating at zero inches static pressure, see the CABP3 Cabinet Blower Data for actual rating. ** Nominal rating at zero inches static pressure. See the blower installation instructions for actual blower rating. ■■ The raised vent can be configured to exhaust through the bottom or either side: ►► On installations using a remote or in-line blower, the cover plate on the appropriate side or on the bottom is removed to expose the exhaust. Configure the raised vent for bottom exhaust and use an elbow to vent through the rear cabinet wall. ►► On installations using the CABP3 blower, the blower assembly is mounted to the front of the raised vent with the exhaust pointing in the desire direction. Point the exhaust down and use an elbow to vent through the rear cabinet wall. ■■ When planning new duct work, always look for the shortest, most direct route to the outside. Calculate the maximum duct length (see following pages) to determine if the planned duct route will work with the blower selected. ■■ On bottom exhaust installations you may cut a hole in the floor to allow the duct work to pass through. ■■ All duct work materials (including screws and duct tape) must be purchased separately by the customer. ■■ 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. ■■ Do not rely on duct 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 require to support the duct weights. ■■ 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. ■■ With concrete slab construction, "box-in" the duct work to prevent it from collapsing when the wet concrete is poured. Also allow room for electrical wiring from the remote blower. ■■ Cross-drafts or air currents from adjacent open windows or doors, heating/air conditioning outlets, ceiling fans and recessed ceiling lights reduce vent efficiency. 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 possible, with as much space between each bend as possible. ■■ For best performance, use round duct instead of rectangular 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 duct. Specifications subject to change without notice. Install all appliances according to accompanying installation instructions. www.Dacor.com Phone: (800) 793-0093 8.11
