KitchenAid 27" Double Wall Oven with Even-Heat™ True Convection Installation Guide

If codes permit and a separate ground wire is used, it is 
recommended that a qualified electrical installer determine that 
the ground path and the wire gauge are in accordance with local 
codes.

Check with a qualified electrical installer if you are not sure the 
oven is properly grounded.

This oven must be connected to a grounded metal, permanent 
wiring system.

Be sure that the electrical connection and wire size are adequate 
and in conformance with the National Electrical Code, ANSI/
NFPA 70-latest edition or CSA Standards C22.1-94, Canadian 
Electrical Code, Part 1 and C22.2 No. O-M91-latest edition, and 
all local codes and ordinances.

A copy of the above code standards can be obtained from:

To properly install your oven, you must determine the type of 
electrical connection you will be using and follow the instructions 
provided for it here.

■

Oven must be connected to the proper electrical voltage and 
frequency as specified on the model/serial/rating plate. The 
model/serial/rating plate is located under the control panel on 
single ovens and under the control panel on the upper oven 
cavity on double ovens. See the following illustrations.

■

Models rated from 7.3 to 9.6 kW at 240 volts (5.4 to 7.4 kW at 
208 volts) require a separate 40-amp circuit. Models rated at 
4.8 kW and below at 240 volts (3.6 kW and below at 
208 volts) require a separate 20-amp circuit.

■

A circuit breaker is recommended.

■

Connect directly to the circuit breaker box (or fused 
disconnect) through flexible, armored or nonmetallic 
sheathed, copper cable (with grounding wire). See “Make 
Electrical Connection” section. 

■

Flexible conduit from the oven should be connected directly 
to the junction box.

■

Fuse both sides of the line.

■

Do not cut the conduit. The length of conduit provided is for 
serviceability of the oven.

■

A UL listed or CSA approved conduit connector must be 
provided.

■

If the house has aluminum wiring, follow the procedure 
below:

1. Connect a section of solid copper wire to the ends of the 

flexible conduit 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.
