Tools needed

Venting Requirements

The vent system must terminate to the outside (roof or side wall).

• 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/aluminum vents only. A rigid metal/ aluminum vent is recommended.
• DO NOT use plastic vents.
• Always keep the duct clean to ensure proper airflow.
• Calculate the following figures before installation:
  1. Distance from the floor to the ceiling.
  2. Distance between the floor to the countertop/ stove (recommend* 28” to 31”).
  3. Distance between the countertop/stove to the range hood.
  4. Height of hood and duct cover.

For the most efficient & quiet operation:

• A distance of 28” to 31” is recommended* between the stove top and the bottom of the range hood.
• It is recommended that the range hood be vented vertically through the roof through 8” (20.3 cm) or bigger round metal/aluminum vent work.
• 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 the vent system and a number of elbows should be kept to a minimum to provide efficient performance.
• The vent system must have a damper. If the roof or wall cap has a damper, DO NOT use a damper (if supplied) on top of the range hood.
• Use silver tape or duct tape to seal all joints in the vent system.
• Use caulking to seal the exterior wall or roof opening around the cap.

Due to different ceiling height configurations, the recommended height may not be applicable.

Height & Clearance

IMPORTANT:

• A minimum of 6” round (standard for this range hood) or 3-1/4 x 10” rectangular duct (purchased separately) must be used to maintain maximum airflow efficiency.
• Always use rigid-type metal/aluminum ducts if available to maximize airflow when connecting to the provided duct.
• Please use the Duct Run Calculation below to compute the total available duct run when using elbows, transitions, and caps.
• ALWAYS, when possible, reduce the number or transitions and turns. If a long duct run is required, increase duct size from 8” to 9” or 10”. If a reducer is used, install a long reducer instead of a pancake reducer. Reducing duct size will restrict airflow and decrease airflow, thus reducing duct size as far away from the opening as possible.
• If turns or transitions are required: Install as far away from the opening and as far apart, between 2, as possible.
• Minimum mount height between stove top to hood bottom should be no less than 28 inches*.
• Maximum mount height between stove top to hood bottom should be no higher than 31 inches*.
• It is important to install the hood at the proper mounting height. Hoods mounted too low could result in heat damage and fire hazard; while hoods mounted too high will be hard to reach and will lose its performance and efficiency.
• If available, also refer to the stove top manufacturer’s height clearance requirements and recommended hood mounting height above range.
• Due to different ceiling height configurations, the recommended height may not be applicable.

Minimum Duct Size:

• Round – 6” minimum
• Rectangular – 3-1/4 x 10” minimum (requires an 8” to 3-1/4×10” adaptor, not supplied)

Calculating Vent System Length

To calculate the length of the system you need, deduct the equivalent feet for each vent piece used in the system from the recommended maximum duct run.

Duct Run Calculation:

Recommended maximum run
8” or 3-1/4 x 10” duct| 50 ft

Vent piece deduction
Each 90º elbow used| 9 ft
Each 45º elbow used| 5 ft
Each 8” to 3/14 x 10” transition used| 7 ft
Sidewall cap with damper| 0 ft
Roof cap| 0 ft

Duct Run Calculation example:

• One roof cap, two 90º elbow, and one 45º elbow used: 0ft + 9ft + 9ft + 5ft = 23ft used.
• Deduct 23ft from 50ft, 27ft maximum available for straight duct run.

Venting Methods

• This range hood is factory-set for venting through the roof or wall.
• Vent work can terminate either through the roof or wall. To vent through a wall, a 90° elbow is needed.

IMPORTANT:

• NEVER exhaust air or terminate duct work into spaces between walls, crawl spaces, ceilings, attics or garages. All exhaust must be ducted to the outside.
• Use metal/aluminum ductwork only.
• Fasten all connections with sheet metal screws and tape all joints with certified Silver Tape or Duct Tape.
• Use caulking to seal the exterior wall or roof opening around the cap.

Troubleshooting

WARNING
Hazard of electrical shock!
Do not perform service on an electrically live system. Disconnect the main electrical supply before servicing this device. Touchingelectrical connectors or other exposed elec trical circuitry inside this range hood, when they are energized, could result in death, se- rious bodily injury, or property damage.

1. If the range hood does not operate after installation:
2. The range hood vibrates when the blower is on:
3. The blowers seem weak:
4. The lights work but the blower is not spinning at all, is stuck or is rattling.
5. The lights work but the blower is not spinning at all, is stuck or is rattling.

• Check if the range hood has been plugged in, make sure that all power has been turned back on and all electrical wiring are properly connected.
• Swap out light assemblies to working ones to determine whether it is caused by defective bulbs. (See Replacing the light bulbs, page 16)
• The range hood might not have been secured properly onto the ceiling.
• Check that the duct size used is at least 8” (20 cm). Range hood WILL NOT function efficiently with insufficient duct size. For example 10” (25.4 cm) duct over 8” (20 cm) hole and loosely secured.
• Check if the duct is clogged or if the damper unit is not opening properly. A tight mesh on a side wall cap unit might also cause restriction to the airflow.
• The blower might be jammed or scraping the bottom due to shipping damage.
• Make sure the distance between the cooktop and the bottom of the hood is within 28” (71 cm) and 33” (79 cm) in range.
• Reduce the number of elbows and length of ductwork. Check if all joints are properly connected, sealed, and taped.3
• Make sure the power is on high speed for heavy cooking

NOTE: For all other inquiries, please contact your local reseller.

MAaintentance&Clean

Caution: Unplug or disconnect the appliance from the power supply
before servicing.
GREASE FILTER

• The grease filters should be cleaned frequently (every two months of operation, or more frequently for heavy use). Use a warm detergent solution.
• Grease filters are washable. Remove the grease filters from the hood. Wash the filters, taking care not to bend them. Allow them to be dry before refitting. When refitting the filters, make sure that the handle is visible from the outside. reinstall the grease filters to the hood.

HOOD CLEANING
Stainless steel is one of the easiest materials to keep clean. Occasional care will help preserve its fine appearance.

Cleaning tips:

• Hot water with soap or detergent is all that is usually needed.
• Follow all cleaning by rinsing with clear water. Wipe dry with a clean, soft cloth to avoid water marks.
• For discolorations or deposits that persist, use a non-scratching household cleanser or stainless steel polishing powder with a little water and a soft cloth.
• For stubborn cases use a plastic scouring pad or soft bristle brush together with cleanser and water. Rub lightly in the direction of polishing lines or “grain” of the stainless finish. Avoid using too much pressure that may mar the surface.
• Do not allow deposits to remain for long periods of time.
• Do not use ordinary steel wool or steel brushes. Small bits of steel may adhere to the surface causing rust.
• Do not allow salt solutions, disinfectants, bleaches, or cleaning compounds to remain in contact with stainless steel for extended periods. Many of these compounds contain chemicals that may be harmful. Rinse with water after exposure and wipe dry with a clean cloth.

Painted surfaces should be cleaned with warm water and mild detergent only.
