Well another question for when i install the blaze king princess. im wondering if it would be worth it for me to set the stove back a couple inches into the fireplace to get a straight up flue. i would have to remove the bottom course of brice in the fireplace to get it to fit.. i would also have to do a block off plate now. or do you think it will be that much of a difference since its a 25 foot flue anyway.
