Venting Requirements 7 Venting Requirements Venting Methods •• Vent system must terminate to the outdoors. •• Do not terminate the vent system in an attic or other enclosed area. •• Do not use 4" (10.2 cm) laundry-type wall caps. •• Use metal vent only. Rigid metal vent is recommended. Plastic or metal foil vent is not recommended. •• The length of vent system and number of elbows should be kept to a minimum to provide efficient performance. For the most efficient and quiet operation: •• Use no more than three 90° elbows. •• Make sure there is a minimum of 24" (61.0 cm) of straight vent between the elbows if more than 1 elbow is used. •• Do not install 2 elbows together. •• Use clamps to seal all joints in the vent system and use furnace duct tape to fully seal joint connection. •• Use caulking to seal exterior wall or roof opening around the cap. •• The size of the vent should be uniform. Vent Exhaust Option The hood is designed for vertical or horizontal discharge. •• Vertical discharge: Use a 31⁄4" x 10" rectangular duct. •• Horizontal discharge: Use a 31⁄4" x 10" rectangular duct. NOTE: Flexible vent is not recommended. Flexible vent creates back pressure and air turbulence that greatly reduce performance. Vent system can terminate either through the roof or wall. To vent through the wall, a 90° elbow is needed. Cold weather installations An additional back draft damper should be installed to minimize backward cold air flow as part of the vent system. A thermal break should be installed to minimize conduction of outside temperatures as part of the vent system. The damper should be on the cold air side of the thermal break. The break should be as close as possible to where the vent system enters the heated portion of the house. Makeup air Local building codes may require the use of makeup air systems when using ventilation systems greater than specified CFM of air movement. The specified CFM varies from locale to locale. Consult your HVAC professional for specific requirements in your area. Vertical Discharge Horizontal Discharge Preparation 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. Fittings material is provided to secure the hood to most types of walls/ceilings. However, a qualified technician must verify suitability of the materials in accordance with the type of wall/ ceiling. Before making cutouts, make sure there is proper clearance within the ceiling or wall for exhaust vent. Hood installation height above cooktop is the users preference. The lower the hood is above the cooktop, the more efficient the capturing of cooking odors, grease and smoke. CAUTION: Mount this hood so that the bottom edge is at 30" (76.2 cm) minimum or 36"(91.4 cm) maximum above the cooking surface. Household use, please, read installation manual for specific application. Check your ceiling height and the hood height maximum before you select your hood.
