I have a Country Flame Crossfire pellet insert and plan to install it in a fireplace in my basement. This will result in a run of 45 feet from the floor up to the top of the chimney. The brick chimney is on an outside wall, and is exposed on the outside of the house above ground level. The run has a jig in it about 10 feet above the basement floor, because there are two flues in the same chimney. The second fireplace is on the ground level, and fires burn very well there. Fires do not draft very well in the basement fireplace where I want to install the pellet insert.
I understand that pellet stoves do not require a draft on the exhaust system, and instead have a fan to produce the appropriate pressure in the exhaust system. I am concerned that this 45' run up my chimney will produce more draft than the stove was designed for. I think that this could result in an improper burn rate in the stove. I have been considering drilling a hole in the chimney for the pellet exhaust, instead of running it to the top of the chimney.
Does anyone have advice on whether a 4" by 45' chimney liner is too long for pellet inserts?
Would it make a difference if I insulated the chimney liner? What about double insulating?
I have an additional question: Does anyone have a recommendation about whether an outside air intake vent would be worthwhile?
