Example calculation 1:
Calculating horizontal extension fig. 2a:
Flue lenght C + E = 1m + 1m 2 m
Elbows D = 2m 2 m
Total horizontal extension 4 m
Measure or calculate effective height (Hvert)
Flue lenght A 1 m
Roof mounted terinal 1 m
Total effective height 2 m
When calculating table 2: It is allowed.
Remove the flue restrictor!
Example calculation 2:
Calculation horizontal extension fig. 2b:
Flue lenght J + L = 0,5 + 0,5 1 m
Elbows K + M = 2m + 2m 4 m
Terminal 1 m
Total horizontal extension 6 m
Calculation effective height (Hvert)
Flue lenght H 1 m
When calculating table nr. 2: Combination not
allowed.
