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 of 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. WARNING — To reduce the risk of fire, use only metal ductwork. This unit must be grounded. Copies of the standards listed may be obtained from: * National Fire Protection Association One Batterymarch Park Quincy, Massachusetts 02269 ** CSA International 8501 East Pleasant Valley Road Cleveland, Ohio 44131-5575 Electrical requirements Important: Observe all governing codes and ordinances. It is the customer’s responsibility: • To contact a qualified electrical installer. • To assure that the electrical installation is adequate and in conformance with National Electrical Code, ANSI/NFPA 70 — latest edition*, or CSA Standards C22.1-94, Canadian Electrical Code, Part 1 and C22.2 No.0-M91 - latest edition** and all local codes and ordinances. If codes permit and a separate ground wire is used, it is recommended that a qualified electrician determine that the ground path is adequate. A 120-volt, 60-Hz, AC-only, fused electrical system is required on a separate 15-amp circuit, fused on both sides of the line. Do not ground to a gas pipe. Check with a qualified electrician if you are not sure range hood is properly grounded. Do not have a fuse in the neutral or ground circuit. IMPORTANT: Save Installation Instructions for electrical inspector’s use. The range hood must be connected with copper wire only. The range hood should be connected directly to the fused disconnect (or circuit breaker) box through flexible armored or nonmetallic sheathed copper cable. Wire sizes (COPPER WIRE ONLY) and connections must conform with the rating of the appliance as specified on the model/serial rating plate. Wire sizes must conform to the requirements of the National Electrical Code ANSI/NFPA 70 — latest edition*, or CSA Standards C22.1-94, Canadian Electrical Code Part 1 and C22.2 No. 0-M91 - latest edition** and all local codes and ordinances. A U.L.- or CSA-listed strain relief must be provided at each end of the power supply cable (at the range hood and at the junction box). For vented models: Vent system requirements 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. Do not use plastic or metal foil vent. Flexible vent is not recommended. Flexible vent creates back pressure that greatly reduces the hood's performance. • The size of the vent should be uniform. • Use no more than three 90° elbows. • Make sure there is a minimum of 24" (61 cm) of straight vent between the elbows if more than one elbow is used. • Do Not install two elbows together. • The length of vent system and number of elbows should be kept to a minimum to provide efficient performance. • The vent system must have a damper. If roof or wall cap has a damper, Do Not use damper supplied with the range hood. • Use duct tape to seal all joints in the vent system. • Use caulking to seal exterior wall or roof opening around the cap. Note: It is recommended that the vent system be installed before installing the...
