Installing a vent/ chimney for a wood stove?

I can’t find the answer to this one. I am thinking about putting in a wood stove. And I am trying to learn how to install a vent/ chimney for it.

Does it have to be a specific material?

Or does it have to be custom sized to your stove or is it one size fits all?

I live in KCMO do I have to build the vent/chimney above my roof I am planning on running out from my basement maybe a window or something like a dryer vent because I don’t think I can run it up my fireplace chimney since the stove will be in the basement.

What is a flu pipe? And how does it differ from the rest of the vent/ chimney?

Any other info would be helpful.

    You’ll have to meet your local building codes. You can contact your local building inspector for those, or, the business you buy the stove from should be knowledgeable about them. Usually, the exhaust is part of the installation by the business.

    In some places you can still use double wall stove pipe. If you use anything other than stainless steel, you should expect to need to replace it every few years. There are minimal clearances you have to observe, and yes, it needs to run all the way to the roof. It cannot end below/near a window, air conditioner, etc. You will probably also need to provide a fresh air intake to the stove.
    For a stove to work properly, it needs to have a certain amount of ‘draw’ through the system – which means the chimney, or exhaust, needs to be of a certain size to match the stove and fresh air intake, so air is properly drawn up from the fresh air intake, through the stove, and out the exhaust stack. You can affect the draw by altering any of a number of factors. Again, the stove dealership should be able to handle all of this for you. You may also be required to have a permit to install the stove and exhaust, and have it inspected.

    I’d recommend you do some window shopping and ask questions of your local dealers.

    In California the vent for a wood burning appliance must be triple wall metal or double wall stainless steel with isulation in between. It comes in even inch sizes depending on the size of the appliance. It is quite expensive and usually cost more than the stove. Minimum clearances must also be observed from combustible materials during installation.Flue pipe, vent, chimney, in your case they all mean the same.

    I seem to remember advising you yesterday to check the regulations for where you live. They may be, and probably are, very similar in California or New Hampshire, and it’s nice to know about them but really the only thing that’s truly useful is to know what is required where you are. If you were out in the toolies somewhere, it might not matter if you followed the rules or not, but in a city it can matter very much.

    It’s very unlikely that where your dryer vent goes out is suitable for a woodstove chimney without some modification.

    If you’re running chimney from a basement window to the roof line and beyond, that probably makes for a very long chimney. The more chimney you have outdoors, the cooler the chimney will stay so the poorer it will draw and the more creosote you’ll probably get.

    Stove pipe has to be stove pipe which is metal, maybe galvanized, maybe black, maybe stainless, maybe single wall, maybe double wall or even triple as mentioned above(I guess California worries about fires and so they should), it depends on code and application. You can’t use anything but stove pipe for stove pipe. It comes in standard lengths and diameters, 6" being the most common diameter.

    However you run it out of the house, you’ll have to observe all the clearances to combustibles. Those vary according to what kind of pipe you use. These days, it’s unusual not to need double wall insulated stainless pipe where it runs through a wall or roof.

    I just searched "wood stove installation missouri" and got a site from the University of Missouri which explains a great deal. There are literally dozens of other sites out there discussing all aspects of wood stoves, their installation and use.

    If you’re trying to get away with installing without inspections, permits, etc, without officialdom knowing what you’re doing, frankly I wouldn’t advise it. If there’s a fire, your insurance company will not pay for the damage if you didn’t have your installation approved. If you didn’t notify them that you now have a wood burning appliance, they probably wouldn’t pay either. If you’re reluctant to call your local building inspector in case they twig that you might be trying to install a stove, you can go down to city hall or to the library if you can’t find the info you need online. You can ask all the questions you like in city hall without telling them who you are and where you live, at least you can where I live. Call to find out when the building inspectors are in. You can probably also call your local fire department to find things out too.
