I'm one of the many newbie's to pellet stoves and have been learning a lot over the last few months from all of you. I had looked at so many stoves and then searched on this forum for the good , bad and ugly on each of them. Overall there are a lot of good stoves to chose from. I finally narrowed it down the the Harman, for it's looks and the features I was looking for. I took the plunge in the middle of May, they had a promotion of 1/2 ton with purchase, so I got 2 tons total and a few extras. It's funny how there are always a few extras, but anyway, one of the extras was to have the exhaust go up through the roof. The exhaust run was about 20 ft and they suggested I go with a 4" vent. It all seemed to go well. After they finished the install, they ran me through the basics of starting and the controls of the stove. I ran it for about an hour on high to cure the stove. That stove cranked out the heat for an 80 degree day! And that had me thinking. The room I put the stove in is were I have my home theater. One of the heat exchanger tubes on each side blows at an angle from the front of the stove. One of them is blowing at the TV. It's more that 4 feet away, do I have anything to worry about. I was hoping that someone has had this problem before.
