Venting Requirements - Elica Sora Série Guide D'utilisation

Venting Requirements

(Ducted models only)
• Vent system must terminate to the outdoors.
• Do not terminate the vent system in an attic or other enclosed
area.
• Do not use a 4" (10.2 cm) laundry-type wall cap.
• Use metal vent only. Rigid metal vent is recommended.
Plastic or metal foil vent is not recommended.
• The length of vent system and number of elbows should be kept
to a minimum to provide efficient performance.
For the most efficient and quiet operation:
• 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 1 elbow is used.
• Do not install 2 elbows together.
• Use clamps to seal all joints in the vent system and use furnace
duct tape to fully seal joint connection.
• Use caulking to seal exterior wall or roof opening around the cap.
• The size of the vent should be uniform.
Cold weather installations
An additional back draft damper should be installed to minimize back-
ward cold air flow and a thermal break should be installed to minimize
conduction of outside temperatures as part of the vent system. The
damper should be on the cold air side of the thermal break.
The break should be as close as possible to where the vent system
enters the heated portion of the house.
Make up air
Local building codes may require the use of makeup air systems
when using ventilation systems with 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.
Venting Methods
The hood is designed for vertical or horizontal discharge.
•
Vertical discharge: Use a 3
•
Horizontal discharge: Use a 3
NOTE: Flexible vent is not recommended. Flexible vent creates back
pressure and air turbulence that greatly reduce performance. Vent
system can terminate either through the roof or wall.

Preparation
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 ef-
ficient the capturing of cooking odors, grease and smoke.
CAUTION
Mount this hood so that the bottom edge is at 30" (76.2 cm) minimum
or 36" (91.4 cm) maximum above the cooking surface. Household
use, please, read installation manual for specific application. Check
your ceiling height and the hood height maximum before you select
your hood.
