Got the stove today hardest part was getting 400 pounds of it out of the truck but I am wondering what I loose by only running the pipe up to the first flue tile in my fireplace. I have a 6" pipe collar on the stove and 16' of 9x12 good clay liner also have a separate flue for the furnace/water heater in the same chimney. Both the fireplace and the furnace/water heater with the smaller flue draft well almost too well at times. Whats the downside to just running the pipe up to the tile?
