Insulating
Stainless
- 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.
The pictures below are just an example.
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 provided 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 stoves are changed continuously, ask your
installer 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;
