SAFETY DISTANCE
· From inflammable objects and support walls in armed concrete:
- A > 1000 mm
B > 550 mm
C > 500 mm
· Any inflammable objects placed above the appliance must be kept at a safe distance: at least 2 metres.
Always take measurements from the outside surface of the appliance (fig. 2).
CONNECTIONS
· Before connecting the appliance, make sure that the data indicated on the data plate meets the needs of the purchase.
· All the biomass heating appliances, in this case, wood stoves, by law must have a chimney flue, built in compliance with regulations on
force, for the evacuation of exhaust fumes.
· The points described below are norms of good construction and installation. They refer to regulations in force (at the time of printing of
this manual) but are not exhaustive in matters of systems and installation.
CHIMNEY OR CHIMNEY FLUE
· The chimney or chimney flue must respect the following requirements:
- It must seal in the exhaust fumes, be water-tight and suitably insulated and isolated in accordance with the conditions of use (UNI
9615);
- It must be made in materials that can resist normal mechanical tress, heat and the action of the products of the combustion and
possible condensation;
- Must be prevalently vertical with deviations of not more than 45° from the axis;
- It must be adequately distanced from combustible or inflammable materials with a cavity or else suitable insulation
- The internal section must preferably be circular; squared or rectangular sections must have rounded corners with a radius not less
than 20 mm;
- It must have a constant internal section that is free and independent;
- Rectangular sections must have a maximum ratio between sides of 1:5;
- The indications given by the manufacturer on the section and construction characteristics of the chimney/flue must be followed. For
particular sections, section or routing variations, check the working efficiency of the exhaust fumes system using the fluidodynamic
calculation (UNI 9615).
- It is recommended that the smoke duct be fitted with a chamber for the collection of solid material and any condensation, located under
the opening of the smoke duct so that it can easily be opened and inspected through the airtight inspection door.
- In case of a fire in the chimney flue, use suitable systems to suffocate the flames (e.g. use a powder or carbon dioxide extinguisher)
and request an intervention of the Fire Brigade.
