36"
Min 28"-Max 36"
*Min 91.5"
*Max 110"
Minimum mount height between range top to
hood bottom should be no less than 28".
Maximum mount height should be no higher
than 36".
It is important to install the hood at the
proper mounting height. Hoods mounted too
low could result in heat damage and fire haz-
ard; while hoods mounted too high will be
hard to reach and will loose its performance
and efficiency.
If available, also refer range manufacturer's
height clearance requirements and recom-
mended hood mounting height above range.
Aminimum of 6" round or 3-1/4” x 10"rectangular
duct must be used to maintain maximum air flow
efficiency.
Always use rigid type metal ducts only.
Flexible ducts could restrict air flow by up to 50%.
Also use calculation (on right) 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 6" to 7 or 8". If a reducer
is used, install a long reducer instead of a pancake
reducer. Reduce duct size as far away from open-
ing as possible.
If turns or transitions are required:
Install as far away from opening and as far
apart, between 2, as possible.
*Minimum ceiling clearance 91.5” at 28”hood
mounting height.
**Maximum ceiling clearance 110" at 36" hood
mounting height.

INSTALLATION 2
DUCTING
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 ductwork only.
Fasten all connections with sheet metal screws and tape all joints w/ certified Silver Tape or DuctTape.
Some Ducting Options:
side wall cap
w/ gravity damper
Soffit or crawl space
Roof Pitch w/
Flashing & Cap

Mounting the Range Hood
1.Add and secure blockings (minimum 2x4 studs)
onto ceiling joist.
2. Center, mark and fasten Ceiling Plate onto ceiling
where hood is to be hung. Make sure front of
bracket is facing as shown on diagram.
3. Determine height of hood, measure and attach four
support arms onto blower unit with screws provided;
use predrilled holes on blower unit and support arms.
Make sure tabs on top of the arms are facing out for the
front, and sideways for the rear, as shown on diagram.
Attach support “U” bracket.
4. Slide telescopic duct covers onto the top of the
blower unit.
5.Attach duct work to the ceiling and position the electrical.
6. Lift blower unit and fasten to Ceiling Plate (lock tabs on
support frame into slots on CeilingPlate); secure support
frame to Ceiling Plate with screws provided.
7. Connect duct work and electrical to the blower unit.
(slide duct covers up to gain access to the top of the
blower unit).

8. Reinstall diffuser panels before
installing filters.

INSTALLATION 6
DUCTLESS CONVERSION
Ductless conversion is intended for applications where an exhaust duct work is not possible to be
installed.When converted, the hood functions as a "purifying" hood rather than an exhaust hood.
Fumes and exhaust from cooking is drawn and filtered by a set of optional Carbon Filters.The air
is then purified and re-circulated back within the home.
We recommend toALWAYS exhaust air outside of the home by employing existing or installing
new duct work, if possible.The hood is most effective and efficient as an Exhaust unit. Only when
the exhaust option is not possible should you recourse to converting the hood into a "purifying"unit.
When converted to be a "purifying" unit, a set of Carbon Filters are required on top of its standard
Metal Filter set.Order according to its Part number below.The standard Metal Filters are intended
to capture residue from cooking and the optional Carbon Filters help to purify fumes exhausted
from cooking for re-circulation.
Carbon Filters (Required)
Ducting
Hood Model: Part No. Filters in pkg.
1. Purchase ductless Charcoal Filters as follow:
2. Remove metal filters on hood. Clip
carbon filters onto each slot opening.
3. Re-install metal filters.
4.Turn on filter change indicator on
control panel (refer details pg. 7)
5. Carbon Filters must be replaced after
every 120 hours of use (or approximately
every 2 to 3 months based on the average
of 1-2hrs. of daily cooking time).The
microprocessor in the controls when set,
will count elapsed usage time and indicate
when carbon filter replacement is required
every 120 hrs.

The standard Metal Filters are required to be cleaned frequently and as recommended in order
to maintain blower efficiency. If improperly maintained,residue from cooking will sift though
filters and cause damage to hood blowers and other sensitive components; and possibly clog
duct work and creates fire hazard.
Filters Change Reminder (Carbon, if fitted):
When your hood is installed as a 'Purifying' (Ductless Recirculating) unit, it is fitted with a set of
Carbon Filters to purify exhaust and fumes from cooking,and re-circulates the air within the home.
These Carbon Filters are required to be replaced after every 120 hours of use.The Filter Change
Reminder function in the microprocessor needs to be switched on.The microprocessor in the
controls when set, will elapsed and count usage time and indicate when carbon filter replacement is
needed every 120 hrs.
