Inox
Isolante
Inox
- It must prevent rain, snow and foreign bodies from getting in.
- It must not be close to other buildings, but have a free outlet that ensures combustion gases are dispersed into the
atmosphere and above all, if the outlet is on a roof, its height must exceed the reflux area.
INSULATION:
- Stainless steel flue: if the flue is located outside, it must be adequately insulated to guarantee good draught and
prevent condensation. If the chimney is built along the outside wall, heat-insulated double-wall tubes or single-wall
tubes with an adequate layer of rock-wool or ceramic fibre insulation are normally used. All chimneys must be pro-
vided with a condensation collecting plug located in the bottom part of the structure. Inside the building, simple
wall tubes can be used, but have the flue sections passing through the roof space or unheated areas well insulated.
- Flue in uninsulated pre-existing masonry: in order to prevent condensation that may be visible outside the flue as
humidity patches, we recommend it is ducted in a stainless steel tube.
ASSEMBLY:
- It must be possible to access all parts of the flue, so that it can be cleaned at regular intervals;
- All sections must be sealed;
- The whole structure must be able to absorb thermal expansion;
- In case of excessive draught, regulators can be fitted, on condition they do not affect the unit normal operation and
guarantee minimum draught. Integration must anyway be carried out by specialized personnel.
-
WARNING: Since the regulations on the installation of pellet boilers are changed continuously, ask your in-
staller for any upgrades.
OTHER USEFUL SUGGESTIONS:
- No other heating equipment must be connected to the chimney;
- The flue must be kept at a safe distance from flammable objects;
- The flue must have the same section as the smoke discharge pipe of the stove, or bigger;
- No other pipe must be located in the flue.
