3 - TYPE AND CHARACTERISTICS OF THE
PIPE CONNECTING THE APPLIANCE TO
THE SMOKE FLUE
•
A connecting pipe must be installed between the
appliance and the smoke flue outlet.
•
The pipe should consist of an "Avis Technique"
approved rigid or flexible multi-fuel tube designed to
be used directly with a closed fireplace. lt should be
noted that the following are forbidden : aluminium,
aluminium steel and galvanized steel ;
•
The following are approved : black plate (min.
thickness 2 mm), enamelled plate (min. thickness
0,6 mm) and stainless steel (min. thickness 0,4
mm).
•
The flue must be visible over its whole length
through a grille or inspection flap and be able to be
swept by mechanical means (Fig. 2).
expansion should not adversely affect the smoke-
tightness of the joins at either end or its mechanical
performance or that of the smoke flue. lts design,
and more especially the connection between it and
the smoke flue, should be such as to prevent the
accumulation of soot, particularly when it is being
swept.
•
Connections to the appliance and the flue should
strictly comply with DTU 24.2.2 and with the
specifications of the pipe ; they should include all
the recommended parts (end pieces and all other
fittings).

4 - DRAUGHT REQUIREMENTS

•
Draught is measured on the connecting pipe at a
point approximately 50 cm above the outlet on the
appliance.
•
The following draught is required for proper working
with the door closed :
6 Pa at reduced speed (0,6 mm WG)
-
12 Pa at normal speed (1,2 mm WG)
-
As there is always some doubt as to any evaluation
of the possible draught
characteristics, it is advisable to systematically
install a damper.
•
The damper ensures that the appliance works
properly, even when the draught is considerable
(high flue, piping). It should be readily visible and
accessible (Fig. 3).
•
The damper does not affect stove performance
when the door is open.

5 - VENTILATION OF THE AREA IN WHICH
THE APPLIANCE IS TO BE INSTALLED
•
The appliance needs air in addition to the air
required by the statutory air change rate. This is
obligatory when the dwelling includes mechanical
ventilation.
•
The air intake should give directly to the outside or
should be located in an area ventilated to the
outside ; it should also be protected by a grille
•
The air supply exit must be located as close to the
appliance as possible. It must be able to be capped
when it emerges directly into the room. While the
appliance is working, make sure that it is free of
any obstruction.
•
The air intake section should be at least equal to
one-quarter of the section of the smoke flue with a
minimum of :
2
50 cm for use with the door closed only
-
2
200 cm for use with the door open or closed
-
(For certain appliances only : see user's
manual).
•
It may be necessary to stop the extractor of the
mechanical ventilation so as to avoid smoke
coming back into the room when the door is
opened.
6 - WALLS IN THE VICINITY OF THE
APPLIANCE
6.1 – Installation advices
Remove all materials that are either combustible or
affected by temperature from walls and inside elements
(doors, walls and ceilings) near the chimney and the
fireplace.
•
The appliance should be encased in MO-rated
incombustible materials.
•
The floor should be of incombustible material from
under the appliance to at least 400 mm in front of
the appliance.
•
If the mantelpiece is made of a combustible
material (a wooden beam, for example), it must be
protected by some sort of incombustible material,
by a deflector or by the fascia (see DTU 24-2-2 and
Fig. 12).
•
If the supporting wall is a light partition wall with
combustible built-in insolation, it must be lined with
incombustible material (10 cm cellular concrete
with a 2 cm cavity across the whole with of the
fireplace extending 5 to 10 cm each side). In this
case the wall will be ventilated by two 20 cm²
orifices.
