Figure 3.3 Example of generator positioning. SIZING AND INSTALLING THE COMBUSTION AIR/FUMES EXHAUST TUBES Series B15 hot air generators can be installed in one of the following ways. - Page 16 The total admitted pressure drop is given in Table 3.1 → 17. The pressure drops of the fumes, air and coaxial tubes supplied by ROBUR, are given in Table 3.2 → 17 (for dia. 80 and 100). The pressure drops of external terminals need not be considered as they are negligible.
