-
the flue gas ducting outfall protruding from the wall must be equipped with an end piece (see fig. no. 19, 20);
-
the whole flue gas ducting assembly is limited by the used elements (see tab. No. 7)
When assembling the flue gas ducting for:
8
–
30 kW
output, the flow resistances summation must not exceed the value of
10;

An example of flue gas ducting calculation for a boiler of 26.5 kW output:
Let's use: 1 x elbow (K90), 1 x bend (O90), 2m of pipe (2 x T80), 1 m of pipe with an end piece (TK80)
The sum of resistances
= 3 + 2 + 2 x 1 + 2 = 9
- is satisfactory
