Declaration

Certificate

1 The actual minimum distance to combustible material from the outer surface of a chimney must be defined according to the designation of the chimney, as described in their marking, and national legal acts. If the legal acts and chimney designation indicate different admissible distances to the combustible materials, it is necessary to follow a bigger distance. Jei teisės aktuose ir koncentrinio dūmtraukio/ortakio žymėjime minėti atstumai skiriasi, tada reikia vadovautis didesniu leistinu atstumu iki degių medžiagų.
