required.
●
If the house has aluminum wiring, follow the procedure below:
1. Connect a section of solid copper wire to the pigtail
leads.
2. Connect the aluminum wiring to the added section
of copper wire using special connectors and/or
tools designed and UL listed for joining copper to
aluminum.
Follow the electrical connector manufacturer's recommended
procedure. Aluminum/copper connection must conform with local
codes and industry accepted wiring practices.
IMPORTANT:
Minimum distance “X”: 24" (61 cm) from electric cooking surfaces
Minimum distance “X”: 30" (76.2 cm) from gas cooking surfaces
Suggested maximum distance “X”: 36" (91.4 cm)

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.
Vent Piece Equivalent Length
45° elbow 2.5 ft
(0.8 m)
90° elbow 5.0 ft
(1.5 m)
The maximum equivalent vent lengths are:
10" (25.4 cm) round vents - 60 ft (18.3 m)
The following example falls within the maximum recommended vent
length.
1 - 90° elbow = 5.0 ft (1.5 m)
1 - wall cap = 0.0 ft (0.0 m)
8 ft (2.4 m) straight = 8.0 ft (2.4 m)
Length of system = 13.0 ft (3.9 m)
VENTING REQUIREMENTS
●
Vent system must terminate to the outdoors.
●
Do not terminate the vent system in an attic or other enclosed area.
●
Do not use 4" (10.2 cm) laundry-type wall caps.
●
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" (61.0 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 the roof or wall cap has a
damper, do not use the damper supplied with the range hood.
●
Use caulking to seal exterior wall or roof opening around the cap.
●
The size of the vent should be uniform.
Venting Methods
Typical Internal Blower Motor System Venting Installations
A 10" (25.4 cm) round vent system is needed for installation (not
included). The hood exhaust opening is 10" (25.4 cm) round.
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.
