2.5 - Environment (Fig. 2)
•
The fireplace must be installed against a wall.
The adjustable tube cover enables the height of
the fireplace to be adjusted to that of the ceiling.
•
The shields supplied with the fireplace provide
heat radiation protection and hide the air cooling
systems designed to protect the walls. It is
imperative that all shields be installed in strict
compliance with the indications below.
•
The fireplace must be connected to the chimney
flue by means of a ∅ 180 mm connecting tube
(see paragraph 3.3).

3.2.1 - Chimney flue type

3.2.1.1 - In the case of a new flue
•
The following materials may be used :
Terracotta chimney blocks in compliance with
-
NF standard P 51-311.
Concrete chimney blocks in compliance with
-
NF standard P 51-321.
Composite metal chimney flues in compliance
-
with NF standards D 35-304 and D 35-303 or
which have been awarded a favorable
"Technical Report" for this purpose.
Terracotta bricks in compliance with NF
-
standard P 51-301.
Fire bricks in compliance with NF standard P
-
51-302.
•
The use of pre-insulated materials avoid having
to install insulation at the job site, particularly for
walls at the attic level and over the height of the
stack (minimum
0.43 m² k/W).
3.2.1.2 - In the case of an existing flue
•
The installer shall bear the responsibility for
all existing sections. The condition of the flue
must be checked
modifications made to ensure proper operation
and compliance with regulations.
•
Sweep the flue, then perform a thorough
examination in order to verify the following
points :
Compatibility of the flue with its usage.
-
Stability.
-
Vacuousness and tightness (Appendix II of
-
DTU 24-1).
thermal resistance:
and the necessary
•
If the flue is incompatible, insert chimney stack
tubing in accordance with a certified procedure,
or install a new chimney flue.

3.2.2 - Minimum flue cross-section

Regulations
Square or rectangular
chimney blocks
Round chimney flues
In all cases, the cross-section of the flue must be at
least equal to that of the connection nozzle on the
appliance.

3.2.3 - A few general recommendations

•
In order to remain hot, a good flue should be
made from materials which are poor conductors
of heat.
•
The trim surrounding the flue should limit the
outside superficial temperature to :
50° C, in inhabited zones.
-
80° C, in uninhabited or inaccessible zones.
-
•
The flue must be perfectly tight, stable and
without internal surface roughness.
•
The flue must not present sudden section
variations (slope off vertical less than 45° ).
•
The flue opening must extend at least 0.4 m
above the ridge of the roof and neighboring roofs.
•
Two fireplaces must not be connected to the
same flue.
•
The flue must enter the room where the fireplace
is to be installed by at least 50 mm.
•
Its inside face must be at least 16 cm from all
wood and combustible material.
•
The flue must not have more than two offsets,
that is to say not more than one non-vertical
section.
Masonry flue :
-
The angle of the offsets must not exceed 45°
for a total flue height under 5 m. For flue
heights greater than 5 m, the offset angle
must not exceed 20° .
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.
