See Annex B for examples of typical flue block types. Flue blocks shall have a maximum of four flues or ventilation passages. 5 Materials 5.1 General The wall or walls of concrete flue liners or concrete flue blocks shall be precast concrete. For multi-wall concrete flue blocks the concrete liner and outer wall may be separated by an air space or insulation. Materials used in the manufacture of system chimneys shall be identified for factory production control purposes. When insulation forms part of a system chimney, it shall be of bonded material as specified by the manufacturer.

When a concrete system chimney is multi-flued with an equal wall thickness, the heat stress test shall be carried out on the flue with the highest designation and temperature. 8.1.2 The distance to combustible material, xx, shall be declared. The maximum temperature measured on the surface of adjacent combustible materials shall not exceed 85 °C when related to an ambient temperature of 20 °C. 8.2 Heat shock resistance 8.2.1 Following the heat stress resistance test in 8.1, when a concrete system chimney designated as soot fire resistant is tested for heat shock resistance in accordance with A.3, at a flue gas temperature of 1 000 °C for a period of 30 min ± 1 min, the block shall subsequently meet the requirements of 8.4 and 8.5. 8.2.2 The distance to combustible material, xx, shall be declared.
