Surely doesn't hurt, ours is also room-air independent, [DIBt] certified. The stove builder then said that the certification could have been saved since the chimney sweep requires a monitor... However, I hardly dealt with the topic of the chimney because there were enough other things to do and we also wanted to first see if the stove was still affordable. Fortunately, it was still possible to get an empty conduit to the chimney... otherwise, it would have turned out badly.
