6-INSTALLATION AND ASSEMBLY
Please bear in mind that:
• All external air inlets must have a closing damper that can be controlled from the outside, along with an insect screen.
• The air inlet section is a net value, so you need to consider the area of any other elements (netting, etc.)
• Periodically clean the filters or netting to ensure the air can pass through
• Do not, for any reason, obstruct the air inlets if the closed fireplace or ventilation kit is running.
FLUE CONNECTION
It is recommended to connect the closed fireplace to the flue via aluminised steel pipes and bends able to resist the high temperatures that
are reached in that tract and smoke corrosion. These connections are available upon request in various sizes (see our price list) and simplify
installation as they are assembled by fitting one inside the other. (fig.7)
Any increases in the section of the fitting must be performed directly over the hood of the fireplace and not along
the chimney flue. Once the installation is complete, it is mandatory to insulate the smoke fitting with ceramic fibre
blanket or material resistant to at least 600° C.
CLADDING AND COUNTER HOOD ASSEMBLY
READ THE "OPERATION TEST" CHAPTER BEFORE STARTING ANY FIREPLACE CLADDING OPERATION.
The closed fireplace and the cladding parts must be fastened together WITHOUT COMING INTO CONTACT WITH THE STEEL STRUCTURE
in order to prevent heat from being transmitted to the marble and/or stone and to allow for normal thermal expansion. Pay attention to
the wood finishes, such as beams or shelves.
It is recommended to set up the counter hood made of 15 to 20 mm thick fireproof plasterboard with a freestanding frame
made of a galvanised profile to prevent bearing the weight on the cladding components (wooden beams or marble lintels), which do not
have a freestanding structure in order to intervene easily in case of anomalies and/or future maintenance.
Dry mount the hearth of the cladding, leaving a 1 cm gap between the fireplace and the hearth for insulation. (fig.8)
