We provide this link to the Mirro manual as a courtesy because people have a hard time finding it online.
This is not an endorsement of the manual as a whole. We’d recommend that you consider referring to it only for operation and maintenance of the Mirro canner. We’d further recommend that you consider not using their suggested food pressure canning directions, because some appear to be out of sync with those of the USDA. For actual canning recipes, you may wish to follow the USDA guide instead.
It’s not clear what year or edition this manual is as it is undated and there is no part number or version number assigned to the manual, either.
Here is the Mirro manual online (over at the Hip Pressure Cooking site; link opens in new window).
