Руководство По Установке для KitchenAid 30-Inch 4-Element Electric Downdraft Slide-In Range

IMPORTANT: This range must be exhausted outdoors unless 

you are using ductless venting. See the “Venting Methods” 

section.

■

 

Do not terminate the vent system in an attic or other 

enclosed area.

■

 

Use an approved vent cap for proper performance. If an 

alternate wall or roof cap is used, be certain the cap size  

is not reduced and that it has a backdraft damper.

■

 

Vent system must terminate to the outside unless you are 

using a ductless vent kit.

■

 

Use a 5" (12.7 cm) or 6" (15.2 cm) round metal vent  

or a 3¼" x 10" (8.3 cm x 25.4 cm) rectangular vent.

■

 

Rigid metal vent is recommended. For best performance, 

do not use plastic or metal foil vent.

■

 

If a joist or stud must be cut, then a supporting frame must 

be constructed.

■

 

The size of the vent should be uniform.

■

 

The vent system must have a damper.

■

 

Seal all joints in the vent system.

■

 

Use caulking to seal exterior wall or roof opening around 

the cap.

■

 

Determine which venting method is best for your 

application.

■

 

Use 26-gauge minimum galvanized or 25-gauge minimum 

aluminum metal vent. Poor quality pipe fittings can reduce 

airflow. For external venting, flexible metal vent is not 

recommended.

 

■

   For external venting, flexible metal vent is not 

recommended. Flexible vent creates back pressure  

and air turbulence that greatly reduce performance.

■

  Local codes may require a heavier gauge material.

■

 

Metal duct may be reduced to 30-gauge galvanized steel 

or 26-gauge aluminized steel if allowed by local codes. 

This reduction is based on information in the International 

Residential Codes Section M1601.1 (2006 edition).

■

 

Avoid installing 2 elbows together.

■

 

Use no more than three 90° elbows.

■

 

Make sure there is a minimum of 18" (45.7 cm) of straight 

vent between the elbows if more than one elbow is used. 

Elbows too close together can cause excess turbulence 

that reduces airflow.

■

 

Do not use a 5" (12.7 cm) elbow in a 6" (15.2 cm)  

or 3¼" x 10" (8.3 x 25.4 cm) system.

■

 

Do not reduce to a 5" (12.7 cm) system after using  

a 6" (15.2 cm) or 3¼" x 10" (8.3 x 25.4 cm) fittings.

■

 

Avoid forming handmade crimps. Handmade crimps  

may restrict airflow.

The length of vent system and number of elbows should be 

kept to a minimum to provide efficient performance.
The maximum equivalent length of the vent system is 60 ft  

(18.3 m). For altitudes above 4,500 ft (1272 m), reduce 

recommended vent run by 20% for best performance.

An additional backdraft damper should be installed to  

minimize backward cold air flow and a thermal break 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.
Order Part Number 708786A for a 5" (12.7 cm) thermal break.
Order Part Number 715557A for a 6" (15.2 cm) thermal break.
To order, see the “Assistance or Service” section of the Use  

and Care Guide.

Local building codes may require the use of makeup 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.

Common venting methods are shown for a downdraft range.  

The downdraft range may be vented through the wall or floor.
