  We apply a recently developed method (V. A. Dzuba, PRA 90, 012517 (2014); J.
S. M. Ginges and V. A. Dzuba, PRA 91, 042505 (2015)) to calculate energy levels
of superheavy elements Uut (Z = 113), Fl (Z = 114), and Fl+. The method
combines the linearized single-double coupledcluster technigue, the all-order
correlation potential method and configuration interaction method. Breit and
quantum electrodynamic corrections are included. The role of relativistic and
correlation effects is discussed. Similar calculations for Tl, Pb and Pb+ are
used to gauge the accuracy of the calculations.
