Hello all! I am readying my hearth for Woodstock's Keystone woodstove, and want to make sure I'm on the right track. Let me know if this isn't the best place to post my questions (seemed like the best fit). First of all, the existing brick hearth (unchanged since 1929) is uneven, and the cement under the bricks is badly cracked. Additionally, there are some cracks in the bricks that surround the firebox. My plan is to remove the bricks of the hearth, patch the cement underneath with thinset (making sure it's level), put the bricks back down, and then build a hearthpad to go over the whole shebang (since the current hearth is only about 20" deep). Is this the best way to deal with the cracked cement and uneven hearth? Any further suggestions? I also have one question about the keystone installation. The horizontal metal bar that's in the firebox is located 27.5 inches from the current hearth. The center rear flu of the keystone is 22.75. Since it's a 6 inch flu (with converter), this will leave 1.75 inches from the top of the flu and the metal bar in my fireplace. I can build a hearthpad that's 1.25 inches, which leaves just half an inch of clearance. Is this ok? Thanks in advance for any advice! This is my first time working on a hearth and installing a woodstove, so I need all the help I can get.
