Hello all, I have been doing a lot of reading on this forum and this will be my first post. We recently moved into a new house (raised ranch) and it has a woodburning fireplace on the top floor. I measured the chimney (on an exterior wall) the other day and it was 13ft ish from the top to the bottom of the fireplace. I have had my eye on a used Blaze King Sirrocco insert on Facebook marketplace and after doing some research I saw that the recommended minimum chimney height was 15ft (which also seems to be a common number across other manufacturers with inserts/stoves). I had a chimney sweep here the other day to clean the chimney before we used it and he said the 13ft would be fine and didn't think there would be an issue. I also talked to someone at an area stove shop and they highly recommended to have a chimney with the minimum chimney height that an insert/stove calls for. So my question to the community is would it be highly recommended to get an appliance that can conform to chimney height or can one still use an insert/stove with a chimney less than 15ft? Thanks
