Cynthia H. from texas asked:
Can I run a class a flue straight off the wood stove all the way in the attic and out the roof?
Can I run a class a flue straight off the wood stove all the way in the attic and out the roof?
No, a freestanding stove must use chimney connector pipe (either single- or double-wall) to the ceiling, where it would then convert to a double- or triple-wall class A chimney pipe.

If you type RUT-76 into our search box, it will bring up some 500-degree and 600-degree silicone sealants. They are offered in different colors.

Unfortunately, you will need to vent the stove up through the ceiling.

With wood-burning stoves and fireplaces, creosote will build up in the chimney. Creosote is a sticky residue that adheres to the inside of the firebox and chimneys and often associated with higher pollution rate. The buildup is usually caused by using firewood with a high concentration of resin or wet firewood. If you are dealing with first or second stage creosote, check out our chimney brushes and cleaners to find what you need to take care of the mess.

Although maintaining pellet and gas stoves is much simpler than the wood-burning variety, consistency is the key to keeping it straightforward. It is recommended that you perform an in-depth inspection annually. As a note, unless you are very familiar with the parts and operation, it is a good idea to hire a professional to do this job. In addition, you should regularly empty the firebox and clear out any dust or soot; also, make sure that the door is secure to avoid leaking carbon monoxide into your home!
