  In the present work we study a warm inflationary model defined by a
quasi-exponential inflaton potential and an inflaton decay rate proportional to
the Hubble rate. The model is characterized by three free parameters. We
compute the power spectrum, the scalar spectral index as well as the
tensor-to-scalar ratio within the framework of the model, and we compare with
the latest Planck data. On the $r-n_s$ plane we show both the theoretical
curves and the contour plots allowed by observations, and we constrain the
parameters of the model accordingly. The non-linear parameter $f_{NL}$,
corresponding to primordial non-Gaussianities, is also discussed and we found
that the value predicted by our model is within the bounds imposed by current
observational data.
