THROUGH CEILINGS AND FLOORS
As per current regulations, flues have to be fitted at a minimum
distance between the inner wall of the flue and the closest
ignitable element (in France; NF-DTU 24.1)
COMBUSTION AIR
Fresh air is essential for good combustion in the hearth. Fresh air
consumption of approximately 40m
CMV type ventilation systems, centralised vacuum systems or
kitchen extractor hoods, may interfere with the operation of the
hearth. Prioritise a direct combustion air supply connected to the
outside. An indirect (unconnected) combustion air supply in the
room is also allowed; respect the following recommendations:
EXISTING MATERIALS
Exterior wall clad with
flammable insulation.
Uninsulated external wall or non-
flammable partition wall (approx.
15cm thick).
Lightweight plaster, wood,
plasterboard, polystyrene,
polyurethane, honeycomb
partitions.

ZONE 1
RECOMMENDED SOLUTION
- Cut away existing insulation
- Build a replacement M0
reinforcement wall
- Special insulation
- Special insulation
- Remove and build a 10 cm thick
wall or,
- Do not remove and build a 10 cm thick
wall in front with a 2 cm air gap or,
- Remove and build a new
supporting wall hard + insulation
Unconnected combustion air
Should the combustion air not be connected directly to the
outside via a duct, then the room must have a permanent supply
of fresh air but without it disturbing the occupants.
The outdoor air intake should face the prevailing winds and have a
minimum section of 1.2 dm², or open into ventilated crawl-space.
The section in cm² of the ventilation grille for the ventilation
chamber must be at least equal to 5 times the surface in m² of the
ventilation chamber.
A permanent outdoor air intake is not necessary if the room is
equipped with a sweep ventilation system, as long as the
supplementary air flow consumed by the appliance while
operating is taken into account (applicable in France under
Decree 24 March, 1982 - articles 8 and 11).
Connected combustion air - attaching the collar
When it is possible to connect the combustion air, prepare the air
supply duct leading to the fireplace. This should have a maximum
length of 2 m, follow the most direct route (otherwise the supply
of air may be insufficient), and end facing prevailing winds or a
technical vacuum. If a grille is used, ensure a minimum free
2
section of 1.2 dm . Attach the supplied air connection collar to the
hearth (specific instructions).
