Most homeowners that are installing a wood stove or freestanding fireplace just want to get the right venting components with the least amount of hassle as possible. There are so many brands, sizes, and types of stove pipe out there that it can get confusing. Today we are going to take a more in depth look at stove pipe right down to what stove pipe is and its uses. Hopefully by the time you have finished this article you will have a better understanding of stove pipe so that the decision is a bit easier on you.
What is Stove Pipe?
Stove pipe, also called chimney connector, is a single or double wall pipe that is used in the exhaust a wood stove or freestanding fireplace. It is used in conjunction with either class A chimney pipe or a masonry chimney. Stove pipe is often confused for class A chimney pipe, though it is not the same. Stove pipe is meant to use inside the home only. More specifically, it only should be used inside the room where the stove is installed. Stove Pipe is used in the venting system from the top of the appliance to the ceiling or wall where it will be converted to class-A chimney pipe or a masonry chimney. Stove pipe cannot be used to pass through combustibles at any point no matter how much clearance is created. The pipe reaches high temperatures that are not safe for being in a close vicinity to any combustible materials.
Single Wall vs Double Wall Stove Pipe
Either type of stove pipe may be used in most applications. Read your appliances owner’s manual to see if there is a requirement for which type of stove pipe is used. Some appliances require you to use double wall for venting or vice versa. Most states require double wall for modular home installations. One deciding factor to which type you will need is the clearance to combustibles around your appliance. If you have a minimum of 18’’ then you will be safe to use single wall stove pipe. If your clearance is less than 18’’ you will have to use double wall stove pipe. Even with double wall stove pipe there has to be a maintained clearance of 6’’. If you do not have at least 6’’ you will need to reconsider the placement of the appliance. Clearances are not an issue? Then the only thing you need to consider is if you would like the pipe to help heat the room. Single wall pipe is going to give off more heat into the room but it will also be extremely hot to the touch. Double wall will give off less heat but will also not be as hot to the touch. It is still not recommended that you grab ahold of a double wall piece of pipe to test the theory.
Choosing a Stove Pipe Diameter
The diameter of stove pipe normally will depend on the size of the flue opening on appliance that you are venting. That size will follow through with the chimney pipe and components as well. However if you currently have chimney pipe installed and the stove you are installing has a different size flue then you will have to consider three choices. First choice is whether to install a stove that has the same flue size as the chimney pipe you currently have. The second choice is to keep with the installation and just increase or decrease the stove pipe to be compatible with the chimney pipe. First thing before making the final decision that this is the way you are going to go, you need to check the owner’s manual to make sure that you can alter the size of the flue. Some stoves will not draft properly with the flue size altered. With this choice you will also have to decide whether to increase at the stove or at the support box. Where you increase will also depend on how your venting system runs; through the wall or through the ceiling. If it is through the wall you will have to increase at the stove but in a through the ceiling you can choose either one. It is recommended that you increase as close to the stove as possible for drafting purposes. The third choice is to replace the existing chimney pipe completely. The first and third choices are the most costly of the three however in some cases one or the other is necessary.
