Pretty much all free standing wood stoves that are installed today use the common stainless steel chimney. You can get this type of chimney in various widths ranging from 4 inch to 8 inch. This all depends on the size of wood stove you have.
There are two different types of chimney you use when installing these wood stoves. Inside the home, you will use an insulated black pipe chimney. This chimney section is what runs from the stove to your ceiling. This section is also telescoping so it can slide from the stove to the ceiling making for a snug fit. The telescoping action is also good for the fact that you can undo this section of chimney and slide it upward when it comes time to do a chimney clean or if you have a catalytic type stove you can raise the chimney to be able to vacum out ash and soot.
Once the chimney goes through the ceiling it will connect to another chimney that is the stainless steel chimney. This section is what run through the ceiling and roof portion of your home and onward to the outside. On top of the last piece of chimney goes a rain cap that is screwed on. These screews can be taken out and the rain cap can be removed for easy access to sweeping you chimney out.
Free standing wood stoves can also be plumbed into old existing brick type chimneys if you home has one although this is not really recomended do to fire regulations and insurance policies. That is why going brand new is always the safeest and most effcient way to go when installing a wood stove.
A lot of people ask about chimney sweeping and how often you should clean your chimney. This will all depend on various factors such as the amount of use your wood stove gets, the types of wood you burn, how hot you get your wood stove burning and how dry your fire wood is. If you are burning green wood or say pine wood that has a lot of creosote in the wood, you will want to be very diligent in keeping your chimney cleaned. Creosote can collect in your chimney and build up causing the inside diameter of your chimney to become somewhat smaller with built up ash and soot. This can cause a build up and if your stove gets too hot can cause a chimney fire as this soot can reignight. Hard woods are usually the best for burning as they have little creosote and pitch in the wood. Softwoods on the other hand tend to have these issues so a regular sweep in recomended. If you use a wood stove as you main source of heat you will want to at least check out your chimney every 90 days and do a sweep. Spring time is a good time also to do an annual cleaning of both the chimney and the fire box itself.
