I'm not an established member here, but I have some experience with kerosene and other heaters, fuel lines, venting pipes and chimneys.

The baseboard heat looks like it may be electric behind that heater, and that is a big no-no.
Better safe than sorry, to many things wrong with this picture.
I think inspectorD has some wise council here.
Things appear to be installed without sufficient bracing. Over time, maybe the unit gets bumped while cleaning or moving furniture. If the pipe shifts, separation at linkage joints or other cracks are possible.
I would also caution that covering this vent pipe improperly could create problems, but I'm sure there are safe options. Brick chimney might work. Cement or ceramic chimney pipe covered with a veneer of more decorative tile also comes to mind. These ideas would probably involve moving the unit farther from the wall.
I don't know how close you want that fuel line to the hot vent, but it might be possible (I don't know codes on this) to enclose it in some kind of appropriate conduit.
Whatever plans, I'd just sacrifice part of the window as a utility area and salvage the remainder of the window and use a smaller curtain.
