Open the furnace.
Put the adapter on the bolt, so the bolt head fits into the slot in
the adapter. This adapter will protect the electrode during
installation.
Being careful not to damage the electrode, place the electrode
over the bolt thread, thinner end first, until it sits in the adapter.
While holding the bolt and adapter onto the electrode, position
the electrode against the inner side of the electrode housing.
