We are having some issues with our pellet stove, many of which have been answered by the other discussions, but this one I did not see. Just a little background - this is our first winter using the pellet stove, but not the first winter the stove has been used. We are currently renting so we don't know everything about the pellet stove, nor do we have the instruction manual for it. So my question is, is it normal to have sparks flying out of the vent? I already believe the vent needs to be extended out from the house farther and vertically, because it is really short and only goes horizontally. Could this be why we are seeing sparks or is this normal?
