All
seals,
insulation,
feedthroughs, and firebreak distances must be
performed in strict compliance with DTU 24-2-2.
3.3 - Type and characteristics of the connecting
tube between the fireplace and the flue
•
A connecting pipe must be installed between the
appliance and the smoke flue outlet. This flue
must be made with either rigid or flexible dual-fuel
tubing, bearing a favorable "Technical Report" for
direct connection to the closed insert.
It should be noted that it is strictly forbidden to
use aluminum, aluminized steel and galvanized
steel chimney flues.
The following are approved : black plate (min.
thickness 2 mm), enamelled plate
thickness 0,6 mm) and stainless steel (min.
thickness 0,4 mm).
•
This flue must be visible over its entire distance
and be able to be mechanically swept.
dilation must not jeopardize upstream and
downstream junction seals nor its mechanical
characteristics or that of the chimney flue. Its
design and particularly the connection with the
chimney flue must prevent the accumulation of
soot, especially during sweeping operations.
•
The junctions with fireplace and the chimney flue
must be performed in strict compliance with DTU
24.2.2 and the tube manufacturer specifications,
using all recommended components (fittings,
connections, etc.).
•
The connecting tube cross-section must be at
least equal to that of the smoke channel on the
fireplace.
•
If the connector is to be horizontal, there should
be an ascending slope of 5 cm per metre.
IMPORTANT :
The area located within a radius of 200 mm around
the connecting tube must be made of incombustible
materials (concrete, bricks). However, the use of
combustible
or
incombustible
degrade above 90° C is authorized provided that the
surfaces subjected to direct heat radiation from the
connecting tube are heat insulated. The insulation
used must bear an MO fire rating (rock wool, ceramic
fibers...) (Fig. 4).
3.4 - Draft conditions
•
The draft is measured on the connecting tube at
approximately 50 cm after the fireplace's smoke
channel.

outlet at the rear.
•
The damper ensures that the appliance works
properly, even when the draught is considerable
(high flue, piping). The damper should be visible
and readily accessible and installed in the same
room as the stove.
•
The damper does not affect stove performance
when the door is open.
(min.
3.5 - Ventilation of the room where the fireplace is
installed
•
Proper fireplace operation requires air intake in
Flue
addition to regulatory air exchange. This air inlet
is mandatory when the residence if equipped with
a mechanical ventilation system.
•
The air inlet must draw air directly from the
outside or be located in a room with ventilation to
the exterior and must be protected by a grille.
•
The air inlet exhaust must be located as close as
possible to the fireplace. The user should be able
to close it off when it comes out directly into the
room. While the appliance is being used, make
sure that it is free of any obstructions.
•
The cross-section of the air inlet must be at least
equal to the cross-section of the chimney flue
with a minimum of 50 cm² for use with the door
closed only.
•
It may be necessary to stop the mechanical
ventilation extractor to avoid smoke being pulled
into the room when the door is opened.
3.6 - Blower electrical connection
which
•
The installation to the fixed 230 V + ground
connection must be made with flexible cable.
•
The connection can be made with :
Either an accessible power outlet.
-
Or a fixed electrical terminal. In this case, the
-
installation must be fitted with an omnipolar
disconnect device having a contact opening
distance greater than 3 mm.
•
The installation must be in compliance with
NFstandard C 15100. In particular, the installation
(door
must be properly grounded (green and yellow
wire).
