на стр35 в таблице непонятно: какая максимальная длина дымохода для модели 140кВт

For a power output of 140 kW, the maximum flue length depends on the type and diameter of the flue system used:

- For Ø130 mm parallel tubes: up to 16 m with no changes of direction.
- For Ø100/150 mm concentric tubes: up to 8 m with no changes of direction.

These values decrease with each change of direction in the flue layout.
