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.).
