1 The actual minimum distance to combustible materials from the outer surface of a connecting flue pipe (for flue liners isn’t applied) must be defined according to the designation of the product, as described in their marking, and national legal acts. If the legal acts and chimney designation indicate different distances to the combustible materials it is necessary to follow a bigger distance.
