Vent system must terminate to the outdoors, except for non-
Roof Venting
vented (recirculating) installations.
Do not terminate the vent system in an attic or other enclosed
area.
Do not used a 4" (10.2 cm) laundry-type
wall cap.
Use a 7" (17.8 cm) or a 31/4 '' x 10" (8.3 x 25.4 cm) round metal
vent. 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.
C
•
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.
•
The vent system must have a damper. If roof or wall cap has a
damper, do not use damper supplied with the range hood.
•
Use caulking to seal exterior wall or roof opening around the
cap.

Cold Weather
Installations
An additional back draft damper should be installed to minimize
backward 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.
Makeup
Air
Local building codes may require the use of make up air systems
when using 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.
Venting Methods
Vent system can terminate either through the roof or wall. Use
31/4 '' x 10" (8.3 x 25.4 cm) with a maximum vent length of
35 ft (10.7 m) or 7" (17.8 cm) round vent with a maximum length
of 50 ft (15.2 m) for vent system.
NOTE: Flexible vent is not recommended.
Flexible vent creates
back pressure and air turbulence that gently reduces
performance.
Calculating
Vent System
Length
To calculate the length of the system you need, add the
equivalent feet (meters) for each vent piece used in the system.
