INSTRUCTIONS FOR THE INSTALLER 9
2.
2.3.6. Connection to the flue
The appliance must be connected to the
chimney flue using special piping designed
to resist the products of combustion (e.g.
stainless steel, enamelled steel, etc.).
To connect the flue to the socket flange,
insert the piping inside the flange and seal
the joint with fire sealant or fire cement to
make it completely airtight.
The installer must ensure that the pipe
connected to the appliance is well secured
and there is no chance of it coming free
from its housing (e.g. as a result of
dilatation due to temperature, etc.).
If you have a cast-iron top surface with
a flue socket on top, the flue can be fitted
either on top or at the rear of the
appliance.
In order to fit the flue socket at the rear
of the appliance, remove parts A and B,
and secure flue socket flange D with two
nuts and bolts. Fit cast-iron cover C on the
top surface.

In order to fit the flue socket on top of

nuts and bolts.

2.4. Chimney flue
The chimney flue must comply with
present standards on the installation of
chimneys.
In rooms equipped with Controlled
Mechanical Ventilation, the ventilation
outlet must never be connected to the
flue.
The appliance must always have its own
chimney flue, never sharing a chimney flue
with another appliance.
2.4.1. Type of flue
The flue must be made of special
material designed to resist the products of
combustion (e.g. stainless steel, enamelled
steel, etc.).
Non-central-heating appliances
(without back boiler) require an insulated,
double-sleeve flue only on those sections
that run outdoors or through cold areas.
Single piping can be used inside the
building, the heat of the gases serving to
heat rooms, insulating only those sections
where excess temperature may cause
damage.
If the chimney is constructed, then it is
necessary to pipe and insulate it to ensure
correct updraught.
The diameter of the pipe must be the
same as the diameter of the flue socket on
