I am looking at getting a larger heater which is 2.5 inches higher out the flue opening than the present heater. I can remove the hearth stone and get down between 1.5 -2 inches lower. The guy at the heater store is telling me they can use a flex piece that will take care of the rest of that. My concern is how is that going to effect my draw on the chimney.
Actually, it would be maybe as much as an inch that the heater was higher than the flue opening through the thimble. Can that work or is it going to give me some problems with draw? The flue goes straight out the back of the heater straight through the wall to the outside. It is double wall SS pipe 6 inch inside measurements. I am in North MS and have had no problems at all with the draw all winter. It is 18 feet tall.
