FLUE OPTIONS

CAUTION: Non accessible flue systems:
▶ Where a flue system is not going to be accessible,
provision must be made for service and inspection.
▶ Voids containing concealed flues must have at least
one inspection hatch no less than 300mm square.
▶ Flue joints within the void must not be more than 1.5
metres from the edge of the inspection hatch.
▶ Inspection hatches should be located at changes of
direction.
▶ If this is not possible, bends should be viewable from
both directions.
NOTICE: Effective flue lengths:
▶ each 90° bend used is equivalent to
2 metres of straight flue
▶ each 45° bend used is equivalent to
1 metre of straight flue
Plume management kits are available for the 60/100
