Before installing the hood
1. For the most efficient air flow exhaust, use a straight run
or as few elbows as possible.
CAUTION: Vent unit to outside of building, only.
2. At least two people are necessary for installation. Wear
gloves to protect against sharp edges.
3. Fittings material is provided to secure the hood to most
types of walls/ceilings, consult a Qualified Installer, check
if they perfectly fit with your cabinet/wall.
4. Do not use flex ducting.
5. COLD WEATHER installations should have an additional
backdraft damper installed to minimize backward cold air
flow and a nonmetallic thermal break to minimize
conduction of outside temperatures as part of the
ductwork. The damper should be on the cold air side of
the thermal break.
The break should be as close as possible to where the
ducting enters the heated portion of the house.
6. Make up air: Local building codes may require the use of
Make-Up Air Systems when using Ducted Ventilation
Systems greater than specified CFM of air movement.
The specified CFM varies from locale to locale. Consult
your HVAC professional for specific requirements in your
area.
All fastener location must span the studs otherwise proceed
as follows:
Cutout drywall along marked lines. Install wood blocking
between studs and make sure it is flush with existing stud
front. Make sure all mounting screws will anchor to added
studs. Replace drywall and refinish.
When used in recirculation mode, To Reduce the Risk of
Fire and Shock use only conversion kit Model: KIT Long
Life.
Use
The hood is designed to be used either for exhausting or filter
version.
Extraction version
In this case the fumes are conveyed outside of the building by
means of a special pipe connected with the connection ring
located on top of the hood.
CAUTION!
The exhausting pipe is not supplied and must be purchased
apart.
Diameter of the exhausting pipe must be equal to that of the
connection ring.
CAUTION!
If the hood is supplied with active charcoal filter, then it must
be removed.
Connect the hood and discharge holes on the walls with a
diameter equivalent to the air outlet (connection flange).
Using the tubes and discharge holes on walls with smaller
dimensions will cause a diminution of the suction performance
and a drastic increase in noise.
Any responsibility in the matter is therefore declined.
! Use a duct of the minimum indispensable length.
! Use a duct with as few elbows as possible (maximum
elbow angle: 90°).
! Avoid drastic changes in the duct cross-section.
Filtration version
The aspirated air will be degreased and deodorised before
being fed back into the room.
In order to use the hood in this version, you have to install a
system of additional filtering based on activated charcoal.
Installation
Specialised personnel must carry out both the electrical
and the mechanical installation.
Do not cut a joist or stud unless absolutely necessary. If a joist
or stud must be cut, then a supporting frame must be
constructed.
Fittings material is provided to secure the hood to most types
of walls/ceilings.
However, a qualified technician must verify suitability of the
materials in accordance with the type of wall/ceiling.
Before making cutouts, make sure there is proper clearance
within the ceiling or wall for exhaust vent.
Hood installation height above cooktop is the users
preference. The lower the hood is above the cooktop, the
more efficient the capturing of cooking odors, grease and
smoke.
