GB 5/16
25254-11-08
In all cases refer to the current legal requirements.
All combustible materials or materials liable to be affected by the tempe-
rature must be removed from the surface, or interior of the floors, walls,
and ceilings where the fireplace is to be located (Z1, Z2, Z3, Z4, Z5) taking
into account the position of the fireplace in the room. (figs. below).
2.1 Floor
Ensure that the existing floor (Z3) is capable of bearing the total load consti-
tuted by the firebox, the fireplace and the hood. If this is not the case, it
must be reinforced. In the loading zone (Z5), we recommend that an easy-
to-clean, non-combustible floor covering be laid (tiling for example).
2.2 Walls
If, after removing the wall coverings (wallpaper, wood panelling, or fabric wall
covering) from the part of the wall to be occupied by the fireplace, the bare wall
does not fall into one of the categories in the table below, take the action recom-
mended.
Surrounding walls:
For all the walls within the distances given (Z1 and Z2), take the precau-
tions detailed in the table below..
Reminder: do not place any combustible objects within 1 m in front
of glazed fire front
2.3 Ceiling
In the area covered by the hood (Z4), insulate using stiff rock wool, after
removing all non-M0 materials.
2.4 Evacuation of the products of combustion
Remove all non-M0 materials or materials liable to be damaged by the
heat. (cf. FR-DTU 24.1 and FR-DTU 24.2).
If the smoke flue already exists; it is essential to:
-
have it swept by mechanical means (flue brush),
-
have the physical state of the chimney checked by a qualified profes-
sional: stability, air tightness, compatibility of the materials, cross
section....
If the chimney is not compatible (too old, cracked), it is necessary to:
-
either fit tubing using a product officially approved as suitable for this
purpose,
-
or reline the chimney,
-
or have a suitable duct built.
2.5 Going through ceilings and floors
Smoke flues must be placed with a minimum of 16 cm space between the
inner wall of the flue and the nearest combustible element.
2.6 Exterior air inlets
If the house is exceptionally well insulated and/or equipped with a mecha-
nical ventilation system or extractor hood, an extra exterior air inlet will be
necessary for the correct operation of the appliance.
This inlet of fresh air must be positioned taking into account the prevailing
winds. It must be possible to close it when the fire is not in use, and it must
have a minimum cross section of 2 dm².
This inlet of fresh air must always be open when the fire is in use.
