Got some more info on that? Recommendation?
Originally my mason said this.
"Your gonna need a 24' chimney with an 8" flue and 6" thimble. The cost is $3000.00 . That includes the footer, going through the deck and sofit with flashing ,and all material."
Now I let him know the KA6 calls for a 8" thimble. And he replied.
"If it's a 8" thimble the whole chimney has to be bigger and its $400 extra."
