Smoke from fireplace not going straight up?

(1) check the pipe to insure no blockage (is damper open ?). I have a wood stove in my basement. Have to clean the chimney out every couple of months due to creosote buildup. In summer , birds sometimes makes nests in chimney. I have my own brush kit to clean the chimney. (2) Did you husband chamber or line up the stove pipe in the correct direction ? A piece of stove pipe is wide on one end and smaller on the other. The pipe should be attached from wide on stove to smaller into the next pipe. So that the smoke flow-es into the smaller pipe end. I know , did not explain this clearly. (3) You may need to extend the pipe on roof higher. The longer the pipe the better the Draft ( sucking power of smoke). Of course, your problem may not be any of the 3 items here. Good Luck !
