Venting Requirements
Vent system must terminate to the outside •
(roof or side wall).
DO NOT terminate the vent system in an at-•
tic 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 •
airflow.
Calculate the following figures before instal-•
lation:
Distance from the floor to the ceiling.1.
Distance between the floor to the coun-2.
tertop/stove (recommend* 27” to 30”).
Distance between the countertop/stove 3.
to the range hood.
Height of hood and duct cover.4.
For the most efficient & quiet operation:
A distance of 27” to 30” is recommended* •
between stove top and the bottom of range
hood.
It is recommended that the range hood be •
vented vertically through the roof through 8”
(17.8 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 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 (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.

IMPORTANT:
A minimum of 8” round (standard for this range hood) or 3-1/4 x 10” rectangular duct (purchased separate-•
ly) must be used to maintain maximum airflow efficiency.
Always use rigid type metal/aluminum ducts if available to maximize airflow when connecting to provided •
duct.
Please use • Duct Run Calculation below to compute total available duct run when using elbows, transitions
and caps.
ALWAYS, when possible, reduce the number or transitions and turns. If 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 reduce duct size as far away from opening as
possible.
If turns or transitions are required: Install as far away from opening and as far apart, between 2, as possible.•
Minimum mount height between stove top to hood bottom should be no less than 27-inch*.•
Maximum mount height between stove top to hood bottom should be no higher than 30-inch*.•
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 loose its performance
and efficiency.
If available, also refer to stove top manufacturer’s height clearance requirements and recommended hood •
mounting height above range.
* Due to different ceiling height configurations, recommended height may not be applicable.
Minimum Duct Size:
Round - 8” minimum•
Rectangular - 3-1/4 x 10” minimum (requires a 8” to 3-1/4x10” 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
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.

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 lters in place. Without these components, operating blowers could catch on to
hair,
ngers 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 re. The risk of
self combustion is higher when the oil has been used several times.
NEVER cook on “open” ames under the range hood. Check deep-fryers during use: Superheated oil may be
ammable.
Cleaning:
The saturation of greasy residue in the blower and lters may cause increased in ammability. Keep unit clean
and free of grease and residue build-up at all times to prevent possible
res.
Filters must be cleaned periodically and free from accumulation of cooking residue (see Cleaning Instructions
on Page 22). Old and worn
lters must be replaced immediately.
DO NOT operate blowers when lters are removed. Never disassemble parts to clean without proper instruc-
tions. Disassembly is recommended to be performed by quali
ed personnel only. Read and understand all
instructions and warnings in this manual before proceeding.
