We present a light curve model of the symbiotic nova PU Vul (Nova Vulpeculae1979) that shows a long-lasted flat peak with no spectral indication of windmass-loss before decline. Our quasi-evolution models consisting of a series ofstatic solutions explain both the optical flat peak and ultraviolet (UV) lightcurve simultaneously. The white dwarf mass is estimated to be ~0.6 Mo. We alsoprovide a new determination of the reddening, E(B-V) = 0.43 +/- 0.05, from UVspectral analysis. Theoretical light curve fitting of UV 1455 A provides thedistance of d=3.8 +/- 0.7 kpc.
