The minimum front distance for the protection of flammable objects is 1 m. The minimum safety distances from
flammable materials must comply with the table – fig 2.1
Every installation must provide for an easily accessible technical space for periodical maintenance.
The stove is provided with 4 adjustable feet to facilitate positioning on not perfectly flat floors. To adjust the height,
tilt the stove slightly and turn the feet as required.
The stove is supplied with the ambient sensor fixed through a wrapper on the back of the stove; we recommend to
remove the wrapper and to locate the sensor in the best position possible as to improve the temperature registration
in accordance with the ambient context and the length of the cable.
As for temperature registration done at a certain distance we reccomend to install the ambient thermostat/ambient
programming clock-thermostat – see. par.4.8.
-The stove cannot be installed in bedrooms, bathrooms and in general in rooms where
another heating unit is already installed without an independent air inflow.
-With wooden floors, install a floor protection base in conformity with the current regulations.
-Suitable fire-prevention devices should be arranged for any eventuality.
-Do not install the stove in places with an explosive atmosphere.

2.3 Air inlet

The stove air inlet pipe or intake is located at the back and is round and 50 mm in diameter.
A quantity of air at least equal to that necessary for combustion must flow in the room where the stove is installed;
therefore the combustion air necessary to ensure correct operation of the stove must be drawn:
from the room, provided there is a wall air inlet near the stove, communicating with the outside and of minimum
area 100 cm² suitably protected externally by a grille and positioned so as not to be accidentally obstructed;
or with direct connection to the outside with an appropriate pipe having a minimum internal diameter of 50 mm
and maximum length of 1.5 m, provided with antiwind protection at the end (down bend).
The air inflow can also be obtained from a room adjoining that of installation, provided the flow can occur freely
through permanent openings to the outside; the room must not be used as a garage, for storing combustible
materials or for activities with fire risk.
2.4 Fume exhaust
The fumes can be exhausted through a connection to a conventional flue or an external duct with double wall or
insulated pipe. The fume exhaust connections must guarantee a minimum draught of 10 Pa so that the evacuation
of fumes is assured in case of a temporary power failure.
- The installer must check the efficiency and state of the flue and its conformity with the local, national and European
regulations.
- Certified pipes and connections with adequate seals guaranteeing their tightness must be used.
- In case of fire, shut down the stove, promptly call the fire department, and avoid continual attempts to extinguish it.
- Clean the flue and respective connection at least once a year.

2.4.1 Types of installation

Listed below are definitions and requirements for correct installation of an exhaust flue in accordance with Italian
Standard UNI10683 (fig 2.2):
FLUE : a vertical duct for collecting and expelling, at an appropriate height from ground, the fumes coming from a
single unit and, where permitted, more than than one.
FLUE technical requirements : it must be fumetight, isolated and insulated depending on its use;
- it must have a mainly vertical path with axis deviation < 45°;
- it must be at a suitable distance from flammable materials with insulation or air gap;
- it must preferably have a constant, free and independent round internal section;
- it is advisable for the flue to have an inspectionable chamber for the collection of solid materials
- and any condensate, placed under the beginning of the fume duct.
FLUE CONNECTION or DUCT: duct or connection element between the unit and flue for evacuation of fumes.
DUCT technical requirements: - it must not cross rooms in which the installation of combustion units is not allowed;
- flexible metal tubes or fibre cement pipes are prohibited;
- the use of counter-sloping elements is prohibited;
- horizontal sections must have an upward slope of at least 3°;
- the length of the horizontal section must be minimal and not more than 3 m;
- there must not be more than 3 changes of direction, without the T union;
- with change of direction > 90° a max. of 2 bends can be used with length in horizontal projection not exceeding 2 m.
- the fume duct must have a constant section and allow the recovery of soot.
