b)   where the chimney is connected with an individual connecting flue pipe connecting more than one appliance in a cascade arrangement.
The case of multiple inlet cascade arrangement is covered by the case a).
This part of EN 13384 deals with chimneys operating under negative pressure conditions (there can be positive pressure condition in the connecting flue pipe) and with chimneys operating under positive pressure conditions and is valid for chimneys serving heating appliances for liquid, gaseous and solid fuels.
This part of EN 13384 does not apply to:
-   chimneys with different thermal resistance or different cross-section in the various chimney segments. This part does not apply to calculate energy gain;
-   chimneys with open fire places, e.g. open fire chimneys or chimney inlets which are normally intended to operate open to the room;
-   chimneys which serve different kinds of heating appliances regarding natural draught, fan assisted, forced draught or combustion engine. Fan assisted appliances with draught diverter between the fan and the chimney are considered as natural draught appliances;
-   chimneys with multiple inlets from more than 5 storeys. (This does not apply to balanced flue chimney.);
-   chimneys serving heating appliances with open air supply through ventilation openings or air ducts, which are not installed in the same air supply pressure region (e.g. same side of building).
For positive pressure chimneys this part only applies if any heating appliance which is out of action can be positively isolated to prevent flue gas back flow.

This European Standard specifies the performance requirements and test methods for system chimneys with plastic flue liners used to convey the products of combustion from appliances to the outside atmosphere under dry and wet conditions. It also specifies the requirements for marking, manufacturer's instructions and evaluation of conformity. This European Standard describes chimney components from which system chimneys can be assembled. This European Standard is not applicable to chimneys with sootfire resistance classification class G. This European Standard is not applicable for chimneys with the following classification: - corrosion resistance class 2 concerning natural wood ); - corrosion resistance class 3; - pressure class N2. This European Standard is applicable to chimneys designed so that no condensate accumulation can occur, e.g. with a minimum inclination of 3° to the horizontal. This European Standard is not applicable - for system chimneys with plastic coated flue liners; - to structurally independent (free-standing or self-supporting) chimneys. Chimneys with components which need further processing during the installation to reach the final material properties are no system chimneys and therefore also not covered by this standard. This European Standard does not cover the requirements for horizontal terminals (as defined for C1 installation types in CEN/TR 1749) regarding aerodynamic behaviour, rainwater ingress and icing behaviour.

This European Standard describes the method of specifying the design, installation criteria for system chimneys, construction of custom built chimneys, and the relining of existing chimneys. It also gives information on commissioning of chimneys.
This European Standard also deals with connecting flue pipes.
This European Standard does not apply to freestanding chimneys covered by EN 13084-1.
This European Standard excludes chimneys designated H (high positive pressure chimneys) and chimneys for room-sealed heating appliances.
For the purpose of this European Standard the term "installation" includes construction.
