Type And Characteristics Of The Connecting Tube Between The Fireplace And The Flue; Draft Conditions; Ventilation Of The Room Where The Fireplace Is Installed; Blower Electrical Connection - deville C07335 Mode D'emploi

Insulated metal flue :
-
The angle of the offsets must not exceed 45°
with a height limitation of 5 m between the top
and bottom of the offset. The total flue height
is not limited.
•
Chimney blocks must be installed with the male
portion facing downward so as to prevent runs
from passing to the exterior.
•
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
materials which 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 M0 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.
•
Required draft
closed) :
6 Pa at reduced burn rate (0.6 mm WC).
-
12 Pa at normal burn rate (1.2 mm WC).
-
•
The installation
recommended. It can be installed :
Either on the connecting tube, in the tube
-
cover, above the tube cover shield, in the case
of an outlet at the top.
Or on the chimney flue, in the case of an
-
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.
3.5 - Ventilation of the room where the fireplace is
installed
•
Proper fireplace operation requires air intake in
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 outlet must be able
to be closed. 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

•
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.
