is it normal for the end of main line on the left hand side to hiss and release steam whenever the heating is on?

    No. The best location is not in a tee at the end of the main where the vent can get water hammered. But you're stuck with that location unless you want to cut in a new tee.

    It would be better to install a new vent and put it on a long nipple to get it up as close to the ceiling as possible.

    What steam pressure are you running at? Is the pressure too high? Should not be over 1.5psi. Lower is much better.
