7.12.11 Flues in voids

Especially for UK:
The flue system must be connected in accordance with the
manufacturers instructions before firing the boiler.
The term void includes ceiling voids, floor voids, purpose built
enclosures, service risers, roof spaces or any other enclosure that
will restrict access to inspect the flue.
To allow visual inspection, without reliance on devices such as
endoscopes, cameras and mirrors, inspection hatches must be
provided along the entire length of the flue.
Hatches must be a minimum of 300 mm×300 mm and positioned
with the edge of the inspection hatch to 1.5 m of any joint and at
changes of direction. Bends should be viewable from both directions
where the inspection hatch cannot be positioned at the bend.
Where suitable access is not provided the appliance must NOT be
commissioned and must be disconnected from the gas supply.
Additionally the entire flue and all flue seals must be installed in
accordance with the requirements of BS5440:
▪ Check if the condensate trap is filled with water and correctly
connected to the boiler.
▪ All flue joints are correctly made, unstressed and adequately
supported.
▪ All parts of the flue can be visually inspected. Ensure suitable
access where flue is positioned within voids.
