CALCULATION OF THE FLUE PIPE LENGTH
When connecting the flue pipes, make sure not to exceed the maximum flue pressure drop
value, or the maximum length in meters of straight pipes recommended for the product,
otherwise the system pressure might decrease.
The flue pipe dimensions can be calculated using the following tables, indicating the corresponding length
in meters of straight pipes, applied to each of the connection components, as well as the pressure drop
value per component. Then compare the calculation result to the recommended maximum flue pipe length
or maximum pressure drop value for each type of Compact Condens model.
The following tables are based on ACV equipment and cannot be applied as a rule.
