I just had my p61A installed. It's a corner installation, and the way the room is currently layed out, we have the output of the blower facing the back of one of our couches, which is about 3' away. The height of the blower output is about an inch higher than the back of the couch. I had hoped that the hot air on a medium-ish blower setting would rise enough over that distance to where I wouldn't be impeding flow too much with the couch. It is not yet clear that this is the case. I have some experimenting to do to see how the overall reach of the stove is affected if I move the couch out of the way... but I was wondering if anyone had a rule of thumb or some experiences of their own to help set my expectations.
