4.5.2. FLUE DAMPER (NOT SUPPLIED)
In case of excessive draught in the flue chimney, combustion may
become unbalanced and consequently less efficient. In this case, in
order to improve combustion efficiency, it is advisable to install a flue
damper directly above the output of the fireplace stove (fig.8).
When the damper is set in the open position the chimney draws at full
draught. Shutting the damper restricts the flow, slowing the rate of
burning.
4.6. INSTALLATION OF CLADDING FRAME AROUND
THE STOVE
The stove support structure and the parts of the cladding must be
attached to one another WITHOUT COMING INTO CONTACT WITH
THE STEEL OUTER CASING to prevent transmission of the heat to
any decorative surfaces (e.g. Marble).
Use care with wood finishes such as beams or shelves, these must be
suitably insulated. In particular, shelves must be placed at a distance of
not less than 30 cm from the upper part of the unit.
We recommend making the stove cavity 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
10mm between the fireplace stove and the fire bed to provide
insulation (fig.9).
4.7. INSTALLATION OF (OPTIONAL)
FINISHING FRAME
An optional finishing frame can be assembled on DC700, which covers
either three or four sides of the product-depending on installation. This
optional frame (available from your DC700 retailer) is assembled at the
end of installation and after the cladding has been completed and is
anchored directly to the insert structure. This frame is designed to
finish and cover the crack that is formed between the metal structure
of the fireplace stove and the wall.
For frame assembly proceed as follows (fig.10):
• Remove door A by unscrewing the two screws B on the upper
part of the fireplace stove
• Insert the frame C until it comes into contact with the cladding
and fasten it with the four screws D
• Reinstall the door A inserting it in the pin of the lower hinge
and fasten it with the screws B
