2.12.2 Separate ducts (Ø 60mm and Ø 80mm)
Constructing outlets for separate ducts indicates the use of the
"air-flue split pipe system". This is to be ordered separately
from the boiler and when connected to the other accessories,
from those listed in the table below, completes the smoke-
outlet/ combustion air inlet assembly.
