The most important part to clean is the little needle jet. I blew water
through mine and after a few tries it squirted a lot farther. I could not
see a difference in the flame but listening to it run with my ear against
the flue there was very noticable difference. Temp dropped 20 degrees (45
to 25) by cleaning that jet. You probably already did that but just in
case.
Reason not wrap the flue, just guessing. Doesn't get hot enough, VW didn't
think it necesssary, a new place to trap moisture.
