      What is used to seal between the wall thimble and the stove pipe? The 6" kit I bought came with a thimble with a much larger diameter than the 6" double wall pipe has. Pipe outside diameter 8" but the inside diameter of the thimble is 10 1/2 inches.

      It sounds like you received the wrong Wall Thimble. Call the manufacturer to resolve the issue.

        How far from the outer wall can the hardware support? The description says the brackets are adjustable, but I am not sure how much space there will be between the pipe and wall.

        The wall bracket adjusts from 2" to 7".

          The description says the kit comes with different lenghts of pipe, and I pick one. At checkout there is no way to specify the length I need. Am I missing something?

          If you need a longer pipe, you would need to buy one of the other kits. The HD system would not allow us to have a dropdown for pipe length.

            Is the thimble useable with double walled 6" pipe? And can the supporting bracket work with a longer pipe through the thimble? I have to clear an overhang on my roof.

                Buyer Beware buying "Kits" from Home Depot Online...verify EVERY component before accepting.
                Beware buying this as a "kit" because if any of the components are wrong Home Depot CANNOT help rectify the problem. I purchased this "kit" in April 2025 but didn't start my project until yesterday, August 7th. I saw that everything was right except the through the wall thimble...which, coincidentally is the MOST important part of the "through-the-wall" kit. I drove an hour to the Home Depot in Rockland, Maine where I had originally picked up the "kit." I've been a Home Depot customer for 20 years and have spend tens of thousands of dollars with them. Not again. This was the last dollar of mine that Home Depot will ever see. I'm going to call the AllFuel company to see if they have any possible way of making this right. All I want to do is swap the wrong thimble for the correct one. I could buy the entire $700 "kit" again and then when it arrives just swap the wrong piece for the right one that I need and return that whole new order with the wrong part...but that would make it look like I'm trying to get away with something. All I want it what I ordered. The excuse that the Home Depot Customer Service Manager at the Rockland Maine Home Depot gave me was that "They" did something and so she cannot help. I was very angry but I believed her and left as soon as I realized nothing I could say could give her the will or the power to help rectify the situation. I'm still hoping that someone at Home Depot can help...or that the AllFuel company will help...but so far it seems that I'm a victim of Buyer Beware...if I was a conspiracy type I'd wonder if they did this deliberately to get an extra $70 from...which is what the single piece costs.

                  Overall quality was excellent. I am giving this 4 stars due to the fact the supplied support bracket for the tee was not drilled properly. The problem was easily corrected and anyone with basic mechanical knowledge can do this. Another issue were the supplied fasteners. They seemed to be of good quality stainless steel, however they seemed a little undersized. Again, easily corrected with my own purchase of fasteners. I would still buy this product again if given a choice.
