  The nanoflare model of coronal heating is one of the most successful
scenarios to explain, within a single framework, the diverse set of coronal
observations available with the present instrument resolutions. The model is
based on the idea that the coronal structure is formed by elementary magnetic
strands which are tangled and twisted by the displacement of their photospheric
footpoints by convective motions. These displacements inject magnetic stress
between neighbor strands that promotes current sheet formation, reconnection,
plasma heating, and possibly also particle acceleration. Among other features,
the model predicts the ubiquitous presence of plasma flows at different
temperatures. These flows should, in principle, produce measurable effects on
observed spectral lines in the form of Doppler-shifts, line asymmetries and
non-thermal broadenings. In this work we use a Two-Dimensional Cellular
Automaton Model (2DCAM) developed in previous works, in combination with the
Enthalpy Based Thermal Evolution of Loops (EBTEL) model, to analyze the effect
of nanoflare heating on a set of known EUV spectral lines. We find that the
complex combination of the emission from plasmas at different temperatures,
densities and velocities, in simultaneously evolving unresolved strands,
produces characteristic properties in the constructed synthetic lines, such as
Doppler-shifts and non-thermal velocities up to tens of km s$^{-1}$ for the
higher analyzed temperatures. Our results might prove useful to guide future
modeling and observations, in particular, regarding the new generation of
proposed instruments designed to diagnose plasmas in the 5 to 10 MK temperature
range.
