I just moved to a three year old house with a large fireplace. A cast iron wood burning/multi fuel stove would fit perfectly in the large opening. My problem is that the stoves I’ve looked at have six inch flue pipe diameters, while the clay liner coming from my chimney has a nine inch diameter. Will I need to have something fabricated or does anyone know a company that has an off the shelf solution that doesn’t cost a fortune?

You should be able to find one off the shelf at a hardware store and just to clarify what others are saying it should be at least 26 gage or better yet 24 gage for wood/coal burning stoves.30 gage is used for ductwork and is too thin.

Always contact a professional on things like this, HVAC, contractor, stove/fireplace installers etc. With that being said, I would suspect the best way is to run a stainless liner all the way out the top to a appropriate cap. Going from a 6" stove flue into the much larger clay liner, the exhaust gasses will lose a great deal of heat as they rise, this will result in less than adequate flow of exhaust as it is cooling and getting heavier as it rises. The full liner costs more, but insures proper operation of your system, independent to the condition of the clay tile chimney itself for years to come. Other things to consider, very likely the clay tile chimney would definitely not be suitable for all types of fuels, once again, all signs point to putting in the proper all fuels liner all the way out the top. That way, you can truly relax by the stove and enjoy it's warmth, without wondering whats going on in your old chimney. John

I suggest you turn to a sheet metal shop and have them fabricate an increaser (or reducer) that will fit the flue on the equipment and the other end fit the chimney. Just make sure it is a tight fit. If you are concerned you can seal around the installation with heat resistant caulk.

There are off the shelf reducers made. Make sure you get the black iron heavy guage flue pipe reducer and not a galvanized heating duct unit.

You should be able to get a six to 9 inch reducer from anywhere, that's not so uncommon. Go to Home Depot, Lowes, any hardware store, Ace

Any supply house will have a reducer. Make sure it is heavy gague and not for ducting.
