3.5 SEPARATE DUCTS
(Optional alternative twin pipe system)
When installing the separate ducts, comply with the require-
ments of the current standards, as well as the following prac-
tical pointers:
– With direct intake from outside, when the pipe is longer
than 1 m, you are recommended to insulate the piping so
as to prevent the formation of condensation on the outside
of the piping during particularly cold periods of the year.
– With the outlet pipe outside the building or in cold indoor
environments, insulation is necessary to prevent burner
ignition failure. In such cases, provide for condensate
drainage.
– If a segment of the flue passes through a flammable wall,
this segment must be insulated with a glass wool pipe insu-
lator 30 mm thick, with a density of 50 kg/m
3 .
The maximum overall length of the intake and exhaust ducts
depends on the head losses of the single fittings installed
(excluding the adaptors) and can reach approximately the
following horizontal measures:
– 30 m for “80 C” model,
– 35 m for “100 C” model
– 40 m for “110 C” model.
For head losses in the fittings, refer to Table 7.
