    from Greeunup, IL asked:
    November 1, 2017
    I have this chimney system for my Superior WRT3042. The instructions call for "waterproof caulk" where the chimney pipe meets the storm collar & flashing, but do not clarify any requirements or part numbers for a sealant product. Obviously, the sealant must be rated for exterior use, but (assuming the wood burning chimney will get hot) what temperature does the sealant need to be able to resist, and do you have a specific product for this purpose?
    1 Answer
    Unless specified by the manufacturer for a specific heat rating, you can use any high-temperature silicone sealant, which normally withstands 600 degrees.

    from Landis, NC asked:
    February 13, 2017
    What's the difference between the interior and exterior vent piping? if the piping is outside the interior walls, but still inside the envelope of the structure is it still interior?
    1 Answer
    The difference is that the interior kit has a choice of a roof flashing, while the exterior does not because it will be framed into a chase on an exterior wall.

    from Havertown, PA asked:
    December 28, 2016
    I will be installing the Osburn 2200 insert. What exhaust pipe should I use going into a fireplace chimney that is in rough shape, (cracked Terra-Cotta title)?
    1 Answer
    The Osburn 2200 insert or any woodburning insert for that matter will require a fully-functional chimney within which to route a 6" diameter stainless steel liner for venting. Your flue will need to be repaired in order to utilize an insert like this and then safely house the stainless steel chimney liner. Assuming this will be repaired, I would be happy to provide a quote for the insert and the appropriate venting components. If interested, please reply with your choice of door overlay, faceplate shroud and trim for the insert (you may also provide your fireplace opening dimensions to confirm proper sizing), and your flue dimensions/chimney height. You may reply to this email or call me (Tyler) at 901-786-6861 to discuss if needed. I will look forward to your response.

    What does chase mean with the exterior venting system?
    1 Answer
    Please note that the item in question is an interior venting kit, however, an exterior chase is a framed structure built for the fireplace and chimney when the fireplace is installed outside of the envelope of the home. This is typically done when the fireplace face is flush with an interior wall to create more space in the home.

    from Austin, TX asked:
    January 30, 2016
    I bought a fireplace insert and this venting kit from you guys for my chimney. I'm now wondering if this interior kit is the right one for a new construction chimney, I was curious when it asked for pitch. Will this kit work in a chimney? Do I just not use the pitch collar? Is the exterior the one I should have ordered instead?
    1 Answer
    The difference between the interior and exterior kits is that the interior kit will come with a roof flashing, as it is made for going directly through your roof, while the exterior kit is meant to be installed through an exterior chase and would require you to fabricate your own flat chase flashing.

    from SC asked:
    December 25, 2015
    Can you tell me how high the top of the chimney of this interior wall venting kit for 8DM FMI/Superior chimney pipe systems must be from the roof? Also, does this require a masonry surround?
    1 Answer
    The manufacturer lists a minimum chimney height for this fireplace of 14'5" measured from the base of the fireplace. In addition, the chimney must extend at least 3' over the highest point of the roof cutout and then 2' over any obstruction measured within 10' horizontally from this point to satisfy code. No masonry surround is required for the chimney.

    from Park City, UT asked:
    November 30, 2015
    Thanks for your help! When determining the over length we need with this Interior wall venting kit for 8DM FMI/Superior chimney pipe systems, do the pipes come in sections since they cannot be cut? How long is each section?
    1 Answer
    Yes, the pipes in this kit are in various lengths, depending on the amount you select. For example, selection of the "12 Feet" option will result in three 4-foot pipes, and if you choose "15 Feet" you would receive three 4-foot pipes and a 3-foot pipe. The lengths cannot be cut and they are made in 1-, 2-, 3-, and 4-foot sections, as well as an 18-inch section.

    I have installed your 8DM chimney pipe and the 12-3/8" outer wall. Is the required 2" clearance to combustibles measured from the 8" pipe or the 12-3/8" outer pipe?
    1 Answer
    The 2" clearance to combustibles is required around the outer 12 3/8" pipe.

    from UT asked:
    November 23, 2015
    I recently acquired an old Tempest stove. I haven't been able to find out much about it online and it seems to be a rare brand. I'm in the process of designing a chimney and I was happy to see the price of this Interior wall venting kit for 8DM FMI/Superior chimney pipe systems. I saw that it had specific requirements about the kind of stoves that can be used in conjunction with this pipe. I was wondering why the restrictions and why isn't it universal? And if I could make this pipe work for my stove?
    1 Answer
    The chimney in question is only suitable for use with fireplaces manufactured by FMI/Superior and would not be able to handle the heat produced by a wood stove. Wood stoves use UL 103 listed chimney that is tested to 2100 degrees. This chimney is acceptable to use with a wood stove as it will always offer a layer of insulation while the FMI/Superior chimney is air-cooled, meaning that it offers no true insulation.

    from WY asked:
    November 22, 2015
    I need a roof bracing kit for this Interior wall venting kit for 8DM FMI/Superior chimney pipe systems. Our chimney extends 7' above the roof line. Do you have bracing kit for this Superior Chimney pipe?
    1 Answer
    This much air cooled chimney should not be exposed to the outdoors as it lacks any insulation from cold weather. Aside from performance issues resulting from a cold chimney, creosote would develop at a high rate. Subsequently, the manufacturer does not offer any type of roof support because the chimney needs to be enclosed in a chase if it is to be exposed over the roof in this fashion.

    from Durango, CO asked:
    August 22, 2015
    I have a metal roof. Could I still use this Single Story Homes interior wall venting kit for 8DM FMI/Superior chimney pipe systems? If not, is there something else that would work for me?
    1 Answer
    While there is no metal roof flashing specifically made for this chimney, the DuraTech All-Fuel DSA Roof Flashing's cone portion could be trimmed down to accommodate the outer diameter of the Superior/FMI chimney.

    1 Answer
    This kit will include a roof flashing, storm collar, pipe lengths, firestop, and a termination cap. The exact flashing you require and overall length of the pipe are selections you must make, using the drop down menus just below the pricing information. As you will see, length combinations between 10 and 30 feet can be selected.

    from Tobyhanna, PA asked:
    January 22, 2015
    I have a terra cotta chimney. Do I need this chimney pipe?
    1 Answer
    This chimney piping must be used in conjunction with the prefabricated FMI and Superior fireplaces. It cannot be used in conjunction with a terra cotta chimney system. Only a fireplace insert can be used in a masonry fireplace. An example is the Osburn 1100 High Efficiency EPA Woodburning Insert with Blower. This uses a flexible stainless steel 6 inch liner up the chimney.

    from Jacksonville, FL asked:
    October 18, 2014
    I have a chimney that is 10 feet high that is located outside of my house enclosed with a flat chimney cover that is 2' x 5' without a pitch. Is this all of the chimney pipe that I would need?
    1 Answer
    The correct kit for your needs will be the Exterior Chase Venting Kit for FMI/Superior 8DM Chimney Pipe Systems - Single Story Homes, as this kit will exclude the flashing. The kit must only be used with compatible FMI, Vantage Hearth, Desa, and Superior fireplaces.

    from Spokane, WA asked:
    August 20, 2014
    I want to order one of your chimney kits, but I need an offset in the pipe. Is there a way to specify that online, or should I call?
    1 Answer
    Offsets will need to be added separately by purchasing the FMI/Superior 8DM 30-Degree Elbow Kit (Set of Two) and adding the appropriate pipe length(s) between the elbows. Please reply with information about your chimney system (height, offset needed--measured center-to-center, etc.), and we can advise further.
