min.
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.
A minimum 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 pan-
cake reducer. 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 ceiling clearance 96.5”at 28”hood

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.
3. Install attachment bracket into metal filter.
4. Clip carbon filter onto bracket.
5. Re-install metal filters.
6. 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.
