Connection to chimney
All the stoves have both back and top smoke outlet that can be connected to an approved steel chimney on
top or directly out at the rear to a chimney.
Make sure that the chimney is tight and that no false draft is caused around neither the cover plate, in
connection with a covered smoke outlet, nor the cleanout door and pipe connections. Please note that
bent and/or horizontal smoke pipes will reduce the effect of the chimney draft.
