I was looking today at the Englander model 30, and I decided to look through the manual online. I was a bit surprised to see in it that it says that this stove should not be installed with a flue greater than 25 feet tall. I have a masonry chimney which is 30 feet, so should I be worried about this, or will I be alright? I will be putting in a chimney liner. I would appreciate your thoughts and knowledge to help me out on this. Thanks
