6.2.1.1 - New Smoke Flue

Use of the following materials:
•
Fireclay flue blocks compliant with French
Standard NF EN 1806.
•
Concrete flue blocks compliant with NF EN
1858.
•
Composite metal pipes compliant with NF EN
1856-1 and NF EN 1856-2 or which have

6.2.1.2 -

Existing Smoke Flue

The installer is responsible for existing parts. He
should check the condition of the flue and carry out
any work required in order to ensure that it is in
proper working order and compliant with the
regulations in force.
He should sweep the flue and then check the
following very thoroughly :
•
Compatibility of the flue with the intended use ;
•
Stability
•
That the flue is empty and smoke-tight (DTU 24-
1, Appendix II).
If the flue is not compatible, make a casing using an
approved method "Avis Technique" certificats (*) or
install a new flue.
(*) French assessment and certification system
6.2.2 – Minimum flue section
Sizing according to standard EN13384-1. In all cases
the cross section of the connecting flue must be at least
equal to the cross section of the nozzle of the
appliance.

6.2.3 - General Recommendations

•
A good flue will be built of materials with low heat
conducting properties so that it stays hot.
•
Flue casing should be such as to limit the external
surface temperature to the following :
- 50° C in living areas
- 80° C in non-living or inaccessible areas
•
lt should be completely smoke-tight, stable and
have no rough spots.
•
There should be no sudden changes in section
(slope in relation to the vertical less than 45° ).
•
It should extend at least 0,4 m above the ridge of
the roof and of adjacent roofs.
•
Two appliances should not be connected to the
same flue.
•
It should come out into the room containing the
appliance at a height of at least 50 mm.
•
Flue blocks should be placed with the male part
towards the bottom so as to avoid any leaks to the
outside.
•
The flue should include no more than two changes
of direction, i.e. no more than one non-vertical
section.
- If the flue is in masonry :
The bend angle should not exceed 45° over a total
flue height limited to 5 m. For any greater height,
this angle should not exceed 20° .
