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.).
2.3.7. Piping air to the firebox
On this model, it is possible to pipe air
to the appliance for combustion straight
from outdoors. We recommend that, if
possible, air be drawn from outdoors for
combustion via a non-closable pipe with a
diameter of 120mm leading to the nozzle
on the bottom-front of the appliance.
If the tube is straight, it can have a
maximum of 12 meters in length. If you use
accessories like elbows, you must subtract
the total length (12 meters) 1 meter for
each accessory used.
This is the best option because it means
that draughts are not created in and
oxygen is not consumed from the room in
which the appliance is fitted. A further
advantage is that there is no danger of
downdraught which may hinder the correct
updraught of the appliance when an
extractor
or mechanical ventilation
appliance is used in the same room as the
central-heating appliance or in another one
alongside it.
Figure No.10 - Conduction of the air intake
for the combustion chamber
If this is not possible, ensure that the
appliance receives air for combustion via
the relevant grille at the bottom of the
hood (in addition to the hood ventilation
grilles).
2.3.8. Exterior Frame. Removal and
assembly
To fit the frame, proceed as follows:
•
