In the archive you will find a model of bio-fireplace Zen working on ethanol. The flame is animated by standard 3ds max modifiers without using third-party plug-ins. Animation is infinite and is only present in scenes VRay (3.60.03) and Corona (1.6.3). There is no animation in OBJ. The model does not use raster textures.
You can see how the animation looks here: https://www.youtube.com/watch?v=CBZck0P_sX4  The manufacturer of the fireplace is Planika.
Dimensions: 1102mm x 565mm x 401mm. Polys: 23780
Verts: 19765
(without NURMS subdivision on the white case of the fireplace). For a more realistic animation rendering I recommend turning Motion Blur on.
