4.7. CONNECTION TO THE FLUE PIPE

We recommend connecting the stove to the flue pipe by means of pipes

and bends in aluminised steel, capable of withstanding the high

temperatures which are reached in that section of pipe, and of resisting

corrosion from the fumes. These connecting pipes are available on

request in various sizes (see our price list), and they simplify

installation, as they are assembled by fitting one into another.

(figure

7)

Any increase in the section of the connecting pipe

must start immediately above the hood of the

fireplace and not along the flue pipe section
When installation is complete, the smoke connection

must be insulated with ceramic fibre matting or

material that is resistant up to at least 600°C.

4.8. INSTALLATION OF CLADDING AND HOOD

LINER

BEFORE YOU START INSTALLING THE CLADDING OF

THE FIREPLACE STOVE, READ CHAPTER 6.2

“OPERATING TEST”

The fireplace stove and the parts of the cladding must be attached to

one another WITHOUT COMING INTO CONTACT WITH THE

STEEL STRUCTURE to prevent transmission of the heat to the marble

and/or stone, and to allow normal thermal dilation. Use care with wood

finsihes such as crossbeams or shelves.
We recommend making the hood liner in fire-resistant

plasterboard of 15/20 mm thickness, with a self-supporting frame in

galvanised profile, so as not put weight on components of the cladding

(such as wooden beams and marble architraves) which do not have a

load-bearing structure and to make it easy to work in the event of

future anomalies and/or maintenance.
Dry install the fire bed of the cladding, leaving an aperture of 1 cm

between the fireplace stove and the fire bed to provide insulation.

(figure 8)

4.9. INSULATING A WOODEN BEAM

The wood beam must be protected with adequate insulation

from heated parts to prevent the risk of fire or damage of the

cladding.

(figure 8)

4.10. INSULATION OF FIREPLACE STOVE

The fireplace stove must also always be separated from nearby

walls and ceilings.
If necessary, use insulating materials to insulate the walls that are in

contact with the unit if they may be damaged or catch fire (walls made

of wood, plasterboard, etc.).
