7. EXECUTION OF SMOKE DISCHARGE
Smoke discharge must comply with regulations in vigour and therefore must happen via the roof and end over
the roof level. The discharge tube must be made out of smooth steel with silicon seal and not be corrugated
flexible type. Furthermore it must be positioned externally and not in closed or semi-closed spaces. For
example: garages, narrow corridors, under closed penthouses or any other places where smoke could collect.
When connecting the stove to a flue, make sure, with a professional chimney sweep, that the flue is perfectly
whole.. Oppositely it is absolutely obligatory to encase the existing flue with material which is suitable enough
to ensure correct functioning (see fig.7).
TYPE OF TUBES FOR FLUES
Rigid painted steel tubes should be used, and should be at least 1.5mm thick, alternatively they can be made
out of stainless steel which is at least 0.5mm thick. The male/female coupling collars must be superimposed by
at least 40mm. For INSERTO CAMINETTO model use 600°C flexible silicon tubing, with double smooth wall
inside, up until connected to the flue.
FLUE TUBING DIAMETER
The diameter of the tubes depends on the type of system. The stove has been designed for tubes with an
80mm diameter, as shown in the table, however in some cases 100mm is advisable. If 100mm diameter tubing
is necessary, connect it to the stove using a "T" pipe connection with a ø80 - ø100 pipe connection (see fig. 8)
Length of tube length less than 5 mt
Length of tube length more than 5 mt
For installations at an altitude above 1200 mt a.s.l.
Note: for every 90° cur ve add 1m and for every 45° add 1/2m. The lengths indicated on the table ar e relevant for vertical tubing.
Horizontal parts must not be longer than two metres.
It is obligatory to use a "T" connection tube (see fig.8) with an inspection plug, as a connection between the
stove and the flue, which will allow both the collection of ash that is deposited inside the tubes and periodical
cleaning of the flue, without the need to dismantle. Seeing that the smoke is under a light pressure, ensure that
the plug for cleaning the flue has a tight fitting and that it remains so after cleaning. Remember to fix it back as
it was and check the conditions of the seal. Check that the connections between various tubes are in order, as
indicated by the manufacturer.
It is strongly advised not to place tubes horizontally, but if absolutely necessary make sure they are placed with
an angle of at least 5°.
If a traditional flue is used it is possible to connect without the need for a "T" connection tube, but you must
check that the flue has a box for collecting ash.
It is advisable to connect to the stove with a horizontal track that is not more than 1m long.
If the lengths of the tubes are correct the flue should have a suction pressure between 10 and 15 Pa.
Do not change sections of tubing half way and above all after a bend or a horizontal tract. Check that there is
no narrowing in the tubing or the flue.
ISOLATION AND DIAMETER OF HOLES IN WALLS OR ON THE ROOF
Once the position of the stove is established and that you have checked that the place of installation is ideal, it
is then necessary to make the hole for passing tubes through the wall. This can vary according to the type of
installation, the diameter of the tube and the type of wall or roof where the hole is made.
N.B.: if the floor can not support the weight of the stove, position a sheet platform of the correct size with
insulation applied on the floor (rock wool) and with a nominal density greater than 80kg/mc
