6.) INSTALLATION AND POWER CONNECTION
After the above assembly procedures have been completed, the oven is
ready for connection to incoming power as follows:
1.
Open the oven and remove the protective packing covering the
heating elements.
2.
Consult an electrical professional and the NEC (National Electric
Code) specifications to select wire size to adequately carry the line
amperage shown in section 1.) Oven Specifications: Connect
electrical service to a fused power source disconnect. Such
disconnect device shall be marked as a disconnect device for the
oven.
3.
For overcurrent protection device selection, please refer to
amperage shown on the oven rating plate.
NOTE: Be sure to check all external strain relief fittings for tightness. See

Note:
Nylon strain relief fittings installed in a threaded connection and exposed to elevated temperature
should be retained with a sealant such as Locktite® to avoid a loose connection when temperature
fluctuates.
