There is a summary of some of the terms at https://www.bl.uk/onlinegallery/onlineex/firemaps/england/northwest/goadlegendmanchester.html, but it does not include "None" so I agree the best guess is no doors or windows
Possibly also, no insurance cover.
Remember the old fire insurance marks or crests that were attached to the fronts of buildings in the early 1800's etc. so the fire brigade knew at the outset whether their efforts to put out a fire or save a building would be financially worthwhile.
