4.3 – Nature and characteristics of the vent
connector between the appliance and the
smoke duct
•
A vent connector must be installed between the
appliance and the outlet of the smoke duct. This
connector must be made by means of a rigid or
flexible multi-fuel casing, justifiable by a favourable
Technical Opinion for a direct closed hearth
service.
lt should be noted that the following are forbidden :
aluminium, aluminium steel and galvanized steel.
The following are approved : black plate (min.
thickness 2 mm), enamelled plate (min. thickness
0,6 mm) and stainless steel (min. thickness 0,4
mm).
•
The flue must be visible over its whole length
through a grille or inspection flap and be able to be
swept by mechanical means. Any expansion should
not adversely affect the smoke-tightness of the
joins at either end or its mechanical performance or
that of the smoke flue. lts design, and more
especially the connection between it and the smoke
flue, should be such as to prevent the accumulation
of soot, particularly when it is being swept.
•
Connections to the appliance and the flue should
strictly comply with DTU 24.2.2 and with the
specifications of the pipe ; they should include all
the recommended parts (end pieces and all other
fittings).
•
If the vent connector is horizontal, there must be an
ascending slope of 5 cm per metre.
4.4 – Draught conditions:
•
Draught is measured on the connecting pipe at a
point approximately 50 cm above the outlet on the
appliance.
•
The following draught is required for proper working
with the door closed :
- 6 Pa at reduced speed (0,6 mm WG)
-12 Pa at normal speed (1,2 mm WG)
As there is always some doubt as to any evaluation
of the possible draught
characteristics, it is advisable to systematically
install a damper.
•
The regulator enables the appliance to work
properly, even under important draught conditions
(high ducts, casing). The regulator must be easily
visible, accessible (Fig. 5) and installed in the room
where the appliance has been placed.
•
The damper does not affect stove performance
when the door is open.
4.5 - Contribution of the necessary air for the
proper working of the appliance
4.5.1 – Ventilation of the area in which the
appliance is to be installed
depending on flue
•
The appliance needs air in addition to the air
required by the statutory air change rate. This is
obligatory when the dwelling includes mechanical
ventilation.
•
The air intake should give directly to the outside or
should be located in an area ventilated to the
outside ; it should also be protected by a grille (see
advised layout Fig. 6).
A : FAVOURABLE
Face in prevailing wind, favour the flow of fresh
air and smokes.
B : UNFAVOURABLE
Face opposite prevailing wind.
•
The air supply exit must be located as close to the
appliance as possible. It must be able to be capped
when it emerges directly into the room. While the
appliance is working, make sure that it is free of
any obstruction.
•
The air intake section should be at least equal to
one-quarter of the section of the smoke flue with a
minimum of 50 cm
closed.
•
It may be necessary to stop the extractor of the
mechanical ventilation so as to avoid smoke
coming back into the room when the door is
opened.
4.5.2 – External combustion air connection
•
The appliance is equipped with an air intake
located at the back that allows a contribution of
external air via an Ø 80 aluminium duct that must
not be longer than three metres.
•
Attach your duct to the nozzle by means of a metal
collar clamp.
NOTA : Under no circumstances should the ventilation
of the room in which the appliance is installed
(Paragraph 4.5.1) be eliminated.
4.6 – Walls in the vicinity of the appliance
•
Place the stove at a distance of at least 300mm
from the back and side walls of the room and from
all combustible materials.
•
To protect the floor from heat radiation, and from
any possible falling fuel, put the appliance on a
reflective metal screen (or a tiled floor) covering the
entire surface of the floor beneath and in front of
the appliance.
•
The appliance must be installed on a floor with a
sufficient load-bearing capacity. If an existing
construction does not satisfy this prerequisite,
adequate measures must be taken (for example,
the installation of a load distribution plate) in order
to enable the floor to support the appliance.
