Double wall chimney system DW50
Double wall chimney system DW50
Double wall chimney system is designed to exhaust combustion products from heating appliances by natural draught.
Chimney system for particular cases must be selected according to the documentation of the heating appliance manufacturer, chimney installation guide and national legal acts.

| 1 The minimum distance to combustible materials from the outer pipe of a chimney must be selected according to the technical specifications of the chimney, as described in their marking and national legal acts. If the legal acts and chimney technical specifications indicate different admissible distances of the combustible materials, it is necessary to select the higher distance. The minimal distance to combustible materials were determined using 200 mm diameter chimneys. The distance to combustible materials for chimneys larger than tested must be increased by a factor. For dn 201-300 mm the factor must be 1 time the distance to combustible material determined for dn 200 mm, for dn 301-450 mm - 1,5, dn 451-600 mm - 2, above dn 601 mm - 4. |
