  It is shown that the H$\alpha$ luminosity and the Thomson optical depth of
the iPTF14hls on day 600 after the detection provide us with the estimate of
the envelope age which turns to be about 1000 days. I propose a model that
suggests an explosion of a massive star with the radius of $\sim
2\times10^{13}$ cm at 450 days prior to the discovery. For the optimal model
the ejected mass is $30\,M_{\odot}$, and the kinetic energy is $8\times10^{51}$
erg. The energy source at the dominant luminosity stage is presumably related
to the relativistic bipolar outflow originated from a disk accretion onto the
black hole. The [O\,I] 6300, 6364 \AA\ doublet in the spectrum on day 600 is
shown to be the result of the emission of at least $1-3\,M_{\odot}$ of oxygen
in the ejecta inner zone. The oxygen distribution is non-spherical and can be
represented either by two components with blue and red shifts (in the optically
thin case), or by one blue shifted component, in the case of optically thick
lines for the filling factor of $\sim 2\times10^{-3}$.
