  All the possible CP-conserving non-linear operators up to the $p^4$-order in
the Lagrangian expansion are analysed here for the left-right symmetric model
in the non-linear electroweak chiral context coupled to a light dynamical
Higgs. The low energy effects will be triggered by an emerging new physics
field content in the nature, more specifically, from spin-1 resonances sourced
by the straightforward extension of the SM local gauge symmetry to the larger
local group $SU(2)_L\otimes SU(2)_R\otimes U(1)_{B-L}$. Low energy
phenomenology will be altered by integrating out the resonances from the
physical spectrum, being manifested through induced corrections onto the left
handed operators. Such modifications are weighted by powers of the scales ratio
implied by the symmetries of the model and will determine the size of the
effective operator basis to be used. The recently observed diboson excess
around the invariant mass 1.8-2 TeV entails a scale suppression that suggests
to encode the low energy effects via a much smaller set of effective operators.
