Venting Requirements

• The vent system must terminate to the outside (roof or side wall).
• Do not terminate the vent system in an attic or another 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 a plastic vent.
• 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(USStandard:36”).
  3. Distance between the countertop/stove to the range hood (recommend* 24” to 30”).
  4. Height of hood and duct cover.

For the most efficient and quiet operation:

• It is recommended that the range hood be vented vertically through the roof through 6” (15 cm) 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 a 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 the 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 the damper supplied with the range hood.
• Use duct tape to seal all joints in the vent system.
• Use caulking to seal the exterior wall or roof opening around the cap.

Height & Clearance

IMPORTANT:

• A minimum of 6” round (standard for this range hood) 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 Duct Run Calculation below to compute the total available duct run when using elbows, transitions, and caps.
• ALWAYS, when possible, reduce the number of transitions and turns. If a long duct run is required, increase duct size from 6” to 7 or 8”. 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 range top to hood bottom should be no less than 24”.
• Maximum mount height should be no higher than 31”
• 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 their performance and efficiency.
• If available, also refer to the manufacturer’s height clearance requirements and recommended hood mounting height above range.

Minimum Duct Size:

• Round- 6” minimum

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
6” 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 6” 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 elbows, and one 45º elbow were used: 0ft + 9ft + 9ft + 5ft = 23ft used.
Deduct 23ft from 50ft, 27ft maximum available for straight duct run.

Venting Methods

• This power pack range hood insert 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.

Charcoal Filter Installation

NOTE:

1. Remove grease filters from the hood.
2. Position the charcoal filters onto the side of the motor, align the mounting points, and turn until it locks. average of 1 to 2 hours of daily cooking time). Available at your local resellers. Re-install grease filters.

Troubleshooting

1. If the range hood does not operate after installation:
   • Check if the range hood has been plugged in, make sure that all power has been turned back on and all electrical wiring is properly connected.
   • Swap out light assembly to working ones to determine whether it is caused by defective bulbs. (See Replacing the light bulbs, page 14)

2. The range hood vibrates when the blower is on:
   • The range hood might not have been secured properly.

3. The blowers seem weak:
   • Check that the duct size used is at least 6” or 3-1/4 x 10”. Range hood WILL NOT function efficiently with insufficient duct size. For example, 7” duct over 6” 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 air flow.

4. The lights work but the blower is not spinning at all, is stuck, or is rattling.
   • The blower might be jammed or scraping the bottom due to shipping damage.

5. The hood is not venting out properly:
   • Make sure the distance between the cooktop and the bottom of the hood is within 28” and 31” in range.
   • Reduce the number of elbows and length of ductwork. Check if all joints are properly connected, sealed, and taped.
   • Make sure the power is on high speed for heavy cooking
