Chimney passing through the ceiling floor level

 

  • Joints between chimney sections and associated locking bands shall not occur within any ceiling joist space or wall/partitions.
  • Fire-stops or Fire-stop/spacers shall be fitted to the frame formed between compartments through which the chimney passes.
  • The lower end of the chimney shall extend at least 150 mm below a non-combustible ceiling, but the required clearance distance from combustibles to the connecting flue pipe must also be respected, usually three times the diameter of the connecting flue pipe eg. 150 dia. pipe = 450mm clearance to combustible.
  • Where the flue pipe connects to the chimney the connection shall be made using our Pipe Connection Length (EDP) or using our P Adaptor which can be supplied with any spigot diameter so suit.

Distance to combustible materials


Therminox has exceptional thermal properties that guarantee a true 50mm clearance to combustible materials.

 

Offsets

 

An offset is acceptable only if the following rules are respected:

  • The chimney system shall have no more than 4 bends in total. 2 bends in the chimney and 2 bends in the flue pipe connection.
  • The offset shall provide a change of direction no more than 45° from the vertical.
  • The run of chimney between bends shall not exceed 20% of the total chimney length.

 

Termination position & heights


For solid fuel appliance

  • Where the chimney passes through a pitched roof more than 0.6m from the ridge the horizontal distance between the roof and the chimney termination shall be not less than 2.3m unless the termination is at least 0.6m above the ridge (excluding any chimney terminal).
  • Where the discharge end of the chimney flue is within a horizontal distance of 2.3m from any adjoining structure or opening into building the termination height shall be not than 1m above that structure or opening.
  • Where the chimney passes through a flat roof or a shallow pitched roof having a slope less than 10°, the chimney termination shall be 1m above the level of the roof at the point of penetration through the structure.

Note: for more details about termination positions, please refer to Building Regulation Part J
