Connection to the flueway must be done using pipes as short as possible
without narrowing or restrictions and with a maximum slope of 45°.
d
Flexible metal or asbestos-cement pipes must not be used.
Pipes and bends or elbows must be made in compliance with current
regulations.
WARNINGS WITH REGARD TO FLAMMABLE WALLS OR CEILING:
If the connection has to go through elements or walls in heat sensitive
flammable materials, create a layer of at least 20 cm insulation around
the pipe. (Fig. 17)
After having drilled a hole in the wall to insert the pipe through into
the flueway, the air gaps must be filled with non-flammable, resilient
materials with a reduced capacity of heat transmission (e.g. lightweight
concrete). (Fig. 18)
Check that the connection to the flueway is gas/smoke-tight, since the
appliance operates in a vacuum.
a
It is recommended that the connector pipes be insulated with
insulating material having the characteristics given in the
paragraph “SUITABLE HEAT INSULATING MATERIALS”.
Check that the pipe does not penetrate too far into the flueway, thereby
choking the pipe for the passage of smoke and combustion gases.

The surround or the lining wall of the firebox must be self-supporting regardless of the materials with which it is made and under no circumstances
must it come into contact with the firebox. Furthermore, the surround must be made with non-flammable materials in compliance with regulations.
For Gruppo Piazzetta S.p.A. surrounds, follow the instructions enclosed with the product.
a
Testing and lighting for first time.
Only a visual inspection can be made in the intermediate stage for fireboxes, and appliances that must be assembled or clad with brickwork or
require the use of cement binders. In this case operation of the whole installation must be tested after all the building works directly connected with
the “
LIGHTING FOR THE FIRST TIME
” test have been completed, following the instructions given in the booklet.
