Installation Requirements VENTILATION Designer Built-In Wall Hoods DTWS Slim Traditional Wall Hood DTWN Tall Traditional Ledgeless Wall Hood UTILITY REQUIREMENTS Proper installation/ducting is extremely important to ensure maximum performance. Use a qualified and trained installer. DUCTING • Check with a qualified and trained installer or local codes for makeup air requirements, if any. • Max. duct run length o For 300 - 1,200 CFM-50' (152.4 m) o For 1,500 CFM-75' (22.9 m) o For general reference only; for longer duct runs, increase duct size and contact a qualified and trained installer. o Straight runs and gradual turns are best; for example, each 90° elbow is equivalent to 5' - 10' (1.52 - 3.05 cm) of straight run. • 7" (17.8 cm) round duct for 300 - 600 CFM; 10" for 900 - 1500 CFM o Never use flexible duct; it creates back pressure/air turbulence and greatly reduces performance. GAS Not applicable ELECTRICAL • Hardwire direct with two-wire ground • 120 VAC/60 Hz • Max. amp usage (rating includes recommended ventilator kit rating)-see Dimensions & Specifications table PLUMBING Not applicable Note: All CFMs are based on tests with 0.1 static pressure. Without applying static pressure (some brands do not), CFM could be greatly overstated.

Note: Maximum amp rating for hoods includes recommended ventilator kit rating. All products must be hard wired with two-wire ground. An interior- or exterior-power ventilator kit must be purchased for installation with all 18"H. hoods.
