IMPORTANT:
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 vent only. Rigid metal/aluminum vent is recommended.•
DO NOT use plastic vent.•
Always keep the duct clean to ensure proper airow.•
Calculate the following gures before installation:•
Distance between the oor to the countertop/stove.1.
Distance between the countertop/stove to the range hood (recommend* 30” to 36”).2.
Height of hood and duct cover/cabinet.3.
For the most efcient & quiet operation:
A distance of 30” to 36” is recommended* between stove top and the bottom of range hood.•
It is important to install the hood at the proper mounting height. Hoods mounted too low could result•
in heat damage and re hazard; while hoods mounted too high will be hard to reach and will loose its
performance and efciency.
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.
Always use rigid type metal/aluminum ducts if available to maximize airow when connecting to pro-•
vided duct.
The size of the vent should be uniform.•

Mount Heights & Clearance
For the most efcient & quiet operation:
ALWAYS, when possible, reduce the number or transitions and turns. If long duct run is required, increase•
duct size from 8” to 10” or bigger size duct. If a reducer is used, install a long reducer instead of a pancake
reducer. Reducing duct size will restrict airow and decrease airow, thus reduce duct size as far away from
opening as possible.
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 efcient performance.•
The vent system must have a damper. If roof or wall cap has a damper, DO NOT use 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 exterior wall or roof opening around the cap. • Please use Duct Run Calculation below to com-
pute total available duct run when using elbows, transitions and caps.
If turns or transitions are required: Install as far away from opening and as far apart, between 2, as possible.•
If available, also refer to stove top manufacturer’s height clearance requirements and recommended hood•
mounting height above range.
* Due to different ceiling height congurations, recommended height may not be applicable.
Minimum Duct Size:
Round - 6” or 8”•
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 1/4 x 10” transition used 7 ft
Side wall cap with damper 0 ft
Roof cap 0 ft
Duct Run Calcuation 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.
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.
Venting Requirements
Page 6
Page 7
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, ceiling, attics or•
garages. All exhaust must be ducted to the outside.
Use metal/aluminum duct work only.•
Fasten all connections with sheet metal screws and tape all joints with certied Silver Tape or Duct Tape.•
Use caulking to seal exterior wall or roof opening around the cap.•

Troubleshooting
If the range hood or halogen light does not operate1.
after installation:
Check if the range hood has been plugged in, make•
sure that all power has been turned back ON, fused
not blown and all electrical wiring are properly con-
nected.
The range hood vibrates when the blower is on:
• Swap out light assembly to working ones to deter-
mine whether it is caused by defective bulbs. See
Replacing the light bulbs on Page 22.
2. The range hood might not have been secured prop-•
erly on to the ceiling or wall.
The blower or fan seems weak:3. Check that the duct sized used is at least 8” or 3-1/4•
x 10”. Range hood WILL NOT function efciently
with insufcient duct size. For example: 10” duct
over 8” hole and loosely secured.
Check if duct is clogged or if damper unit (half-cir-•
cular apper) is not installed correctly or opening
properly. A tight mesh on a side wall cap unit might
also cause restriction to the air ow.
The lights work but the blower is not spinning at all,4.
is stuck or is rattling.
The blower might be jammed or scraping the bot-•
tom due to shipping damage. Please contact us im-
mediately.
The hood is not venting out properly:5. Make sure the distance between the stove top and•
the bottom of the hood is within* 30” and 36” in
distance. *Due to different ceiling height congura-
tions, recommended height may not be applicable.
Reduce the number of elbows and length of duct•
work. Check if all joints are properly connected,
sealed, and taped.
Make sure the power is on high speed for heavy•
cooking.

Use and Care Information
Operations:
Read and understand all instructions and warnings in this manual before operating the appliance. Save these•
instructions for future reference.
Always leave safety grills and filters in place. Without these components, operating blowers could catch on to•
hair, fingers and loose clothing.
NEVER dispose cigarette ashes, ignitable substances, or any foreign objects into blowers.•
NEVER leave cooking unattended. When frying, oil in the pan can easily overheat and catch fire. The risk of•
self combustion is higher when the oil has been used several times.
NEVER cook on “open” flames under the range hood. Check deep-fryers during use: Superheated oil may be•
flammable.
Cleaning:
The saturation of greasy residue in the blower and filters may cause increased inflammability. Keep unit clean•
and free of grease and residue build-up at all times to prevent possible fires.
Filters must be cleaned periodically and free from accumulation of cooking residue (see• cleaning instructions
on Page 18). Old and worn filters must be replaced immediately.
DO NOT operate blowers when filters are removed. Never disassemble parts to clean without proper instruc-•
tions. Disassembly is recommended to be performed by qualified personnel only. Read and understand all
instructions and warnings in this manual before proceeding.
