So my installer got back to me. Per them "your stove should be fine to install without an outside air kit, you would have to have the equivalent of a double wide or tiny house to need an outside air kit."It depends. If the house is very tightly sealed then it may be necessary. Have you searched on OAK here? There is a lot of info and many threads. There is also a long discussion in the Sweep's Library in the Articles section.
