6 .4 Furnace flue gas system
A flue gas system must be fitted on the furnace as a
means of guiding the flue gas to the chimney. In the
flue gas system there should be a low negative pressure
thanks to the draught of the chimney or an exhaust fan.
The flue gas system on the furnace should be fitted
flush with the eductor (± 10 mm). The diameter of the
flue gas pipe on the furnace should be twice the educ-
tor diameter
P
. If the diameter is too small, even with
the EJEK..AGK with flue gas valve there is the danger of
hot flue gases creeping through the burner when it is
switched off.
The branch lines from the furnace flue gas manifold to
the individual burners should be designed such that
condensate cannot seep upstream into the burner.
