Ferroli ATLAS D 30 SI UNIT Instrucciones De Uso, Instalación Y Mantenimiento página 38

After installation, the unit becomes a "C type" with sealed chamber and forced draught.
The air inlet and fume outlet must be connected to one of the extraction/suction systems
specified below. The unit is approved to operate with all the Cxy flue configurations given
in these instructions. Some configurations may be expressly limited or not permitted by
law, standards or local regulations. Before proceeding with installation, check and care-
fully observe the above instructions. Also, comply with the provisions on the positioning
of wall and/or roof terminals and the minimum distances from windows, walls, ventilation
openings, etc.
B
This C-type unit must be installed using the inlet and fume exhaust ducts sup-
plied by the manufacturer in compliance with UNI-CIG 7129/92. Failure to use
them automatically invalidates every warranty and relieves the manufacturer of
any liability.
Expansion
For fume exhaust pipes longer than 1 metre, during installation take in account
A
the natural expansion of the materials when the boiler is operating.
To prevent deformations, leave an expansion space of approx. 2 ÷ 4 mm for
every metre of pipe.

Connection with coaxial pipes
fig. 25 - Examples of connection with coaxial pipes (
The unit is arranged standard for coaxial connection. Only use ducts with inside in stain-
less steel. Any horizontal sections of the fume exhaust must be kept sloping slightly to-
wards the outside, to prevent condensate from flowing back towards the unit.
Before proceeding with installation, check with table 2 that the maximum permissible
length is not exceeded, bearing in mind that every coaxial bend gives rise to the reduc-
tion indicated in the table. For example, a Ø 80/125 duct comprising a 90° bend + 1 ver-
tical metre has a total equivalent length of 2 metres.

Before proceeding with installation, check the baffle to be used and make sure the max-
imum permissible length has not been exceeded, by means of a simple calculation:

Completely establish the layout of the system of split flues, including accessories
and outlet terminals.
Consult the table 4 and identify the losses in m
ponent, according to the installation position.
Check that the sum total of losses is less than or equal to the maximum permissible
length in table 3.
