FLUE SYSTEM
((Fumes duct, flue and chimney pot
Fumes duct, flue and chimney pot))
Thsi chapter has been drawn up pursuant to European
regulations EN 13384, EN 1443, EN 1856 and EN
1457. The installer must observe both these and any
other local regulations. This manual does not in any
way substitute such regulations.
The product must be connected to a flue system which
ensures that the fumes produced by combustion are
exhausted in complete safety.
Before positioning the product, the installer must
check that the flue pipe is properly rated.
THE FUMES DUCT
THE FUMES DUCT
Further to the general prescriptions for the fumes duct
and flue, the fumes duct::
• may not be made of flexible metal material
• must be insulated, if routed through unheated
areas or outdoors
• must not be routed through rooms in which the
installation of combustion heat generators is
prohibited, or subject to fire hazard, or which
cannot be inspected.
• must enable the recovery of soot and be open for
inspection
• must have at most 3 bends, through an angle of
no more than 90°
• must have a single horizontal section of length
no more than 3 metri, depending on the draw.
Note in any case that long sections promote the
accumulation of dirt and are harder to keep clean.
EXTERNAL AIR INTAKE
In general, we suggest two ways for ensuring a proper
flow of combustion air.
Indirect air intake
Install an intake at floor level with effective area (net of
the mesh or other protective equipment) of at least 80
cm
2
(10 cm dia.).
To prevent draughts, we recommend installing the
intake behind the stove or behind a radiator.
Installing it in front of the appliance will create
unpleasant draughts.
Direct air intake
Install an air intake of effective area (net of the mesh or
other protective equipment) at least equal to that of the
air intake at the back of the product.
Connect the air intake to the appliance’s air intake
with a tube (which may also be flexible). Increase the
diameter of the pipe if it is not smooth: assess its load
loss.
We recommend not exceeding a 5 m length and not
curving the tube at most 3 time, depending on the
draw of the flue.
The air maty be drawn from an adjacent room only if:
• the flow is taken from permanent and unobstructed
openings communicating with the outdoors;
• the adjacent room is never in underpressure
relative to the outdoors;
• the adjacent room is not a garage. subject to fire
hazard, a bathroom or bedroom
• the adjacent room is not a shared room in the
condominium.
