Stove at 625 flue 525. Damped primary full again and same reaction on secodary burn. Opened it back up to 35%. Seeing white smoke out of the stack, not much but smoke all the same. Thought that should not happen with the new stove. Don't think it's steam because it stays up and does not dissapate for 100 feet. Pretty sure the next thing to contemplate will be how long to leave the 30 after the load before I shovel it clean and disconnect it.
