Use Of A Traditional Type Chimney - LASIAN AUDAX 6 KW User And Installation Manual

The "Equivalent load loss" of an installation, is the result of the sum of total meters to install (which
includes the losses of the two bends and the "T" connection), plus the additional losses resulting from the
application of the above table.
The sum of these losses should be less, or at most equal to the maximum allowable length which is
indicated in the table of limitations. If it were not so, we must increase the diameter of the duct to install:

5.4.3- USE OF A TRADITIONAL TYPE CHIMNEY

If you wish to use an existing chimney it is strongly recommended that you have it checked by a professional
chimneysweep to ensure that it is completely airtight. The reason for this is that the smoke, because it is slightly
pressurized, can infiltrate any cracks in the flue and escape into living spaces.
If upon inspection you find that the chimney is not completely sound, it is recommended that you insert piping
made of new material.
If the existing chimney is wide enough, we recommend a pipe with a maximum diameter of 150 mm; it is also
recommended that you insulate the chimney flue. Fig. 5.7 and 5.8 represent the solutions to be adopted if you
want to use an existing chimney.
