Installing a chimney liner for a fireplace insert can be  difficult with out the right parts and knowledge.   Many times you will be using a 6″ chimney liner and sometimes an 8″ chimney liner.  Almost always you will have to do some modification to get the liner thru the damper area of the fireplace.

The best thing to do is remove the damper and possibly a few bricks or part of the metal fireplace to allow the chimney liner to pass thru round to connect to the fireplace insert.  This will give you the best draft, keeping the liner round.  If you think this option is beyond your skill level or there are other reasons you do not want remove the damper housing, you can slightly oval the chimney liner.  The Flex king can be ovaled at home and made round again with your hands to use the round components that come with the chimney liner kit.  The Flex King Pro cannot be made oval with your hands with out damage, it needs a special machine to oval the liner.  It is available just ask your sales representative.

There are other issues you may have installing a chimney liner for your fireplace insert.  You may need to use an offset box, or an insert boot if you do not have a round flue outlet on the stove, or possibly an adjustable elbow on the end of the chimney liner.

As seen above, the liner will need to come all the way down into the the top of the stove.  This specific install will require an offset box to complete the chimney liner installation.
