•
The pipes must always have an
upward slant to facilitate movement by
air density.
•
On routes with a lot of load loss (a
lot of retention), air movement can be
forced along the ducts using a motor or
fan, provided that it is designed to
withstand such temperature conditions.
Bear in mind that air ducts mean that
noise travels more easily from one room to
another.
The following table shows the heat
output of the air from the hot-air outlets
with the appliance working at Nominal

Table showing heat output of the
air leaving the appliance
Note:
The values shown in the above
table were measured at the appliance
output point and based on tests performed
at nominal heat output and maximum fan
speed.
All hot-air ducts lose heat, meaning that
the heat output obtained at the end of
piping always depends on its design.
2.3.8.
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. 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.
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).
2.3.8.1.
Combustion-air intake and hot-air
output installation options
Different installation systems need to
be borne in mind depending on the source
of combustion air (air from outdoors or
from inside the room in which the
appliance is fitted) and the hot-air output
system (air output by natural convection or
by forced convection involving a fan) to
ensure that ITACA-INCA appliances work
properly. There now follows a description
and image of each of these options:
