Ha! I see that your right upper cabinet is exactly as wide as a Symfonisk. That’s convenient 😃.
Here’s a BlueStar thing I haven’t seen mentioned elsewhere: they make a set of gauges for setting the aperture of your air shutters (as seen in this video), but they don’t come with the unit, nor are they sold via BlueStar’s website. I asked my dealer if he had a set I could borrow and he had BlueStar send one to me gratis. With them I was able to confirm that my shutters were at factory spec, but perhaps more importantly, if I should ever decide to try tweaking them, I’ll be able to return them to spec if need be.
