    Question:

    We are in search of the proper connection for the six inch elbow joint pipe which fits to the back of the stove (fisher) and connects to the flue pipe. The six inch we purchased at Lowe's Hardware does not fit inside or outside. They seemed to have no other appropriate products. We need to find this part



    Answer:

    These stoves were made before they really thought the connection process through, and therefore the pipe often does not fit as it should. Ideally, the crimped end of the 6 inch elbow should fit INSIDE the flue collar of the stove. The logic here is that liquid creosote and water that builds up inside the stovepipe will run back inside the stove instead of out onto the floor. When we run into these situations, we usually use a crimping tool to give the pipe what we call an "Old Mill Crimp" (named after a stove like the fischer with similar problems). This "super crimp" makes the pipe closer to 5 1/2 inches OD, which allows it to slip into the stove collar. Some furnace cement and a screw or two drilled through the collar complete the job.
    On the other hand,
    I would recommend the use of a "T" in this application, even though a elbow will work. A "T" makes it easier to clean, and keeps water out of your stove which helps prevent rust.
