1.11 CONNECTION TO THE FLUEWAY
Connection to the flueway must be done using pipes as short as
possible without narrowing or restrictions and with a maximum slope
of 45° from the vertical..
Flexible metal or asbestos-cement pipes must not be used
Pipes and bends or elbows must be made in compliance with current
r
egulations
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. 21)
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. 22
Check that the connection to the flueway is gas/smoke-tight, since
the appliance operates in a vacuum.
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.

1.12 LINING WALL
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.
Testing and lighting for first time
Only a visual inspection can be made in the intermediate stage for fireboxes, stoves 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.
