4.3 Tables for determining the right flue restrictor
Calculate the total horizontal- and vertical length of the flue, according
to the calculations displayed above. Determine according to tables 2, 3, 4
and 5 on the following pages the right flue restrictor size. When meeting
an X, and when the values are outside the table, the combination is not
allowed. Normally the 30 mm flue restrictor is preinstalled.
