Checking the balanced flue system for soundness (annular
gap check)
A
Combustion air test port (ventila-
tion air)
The flue pipe is deemed to be sound if
the CO2 concentration in the combus-
tion air is no higher than 0.2 % or the
O2 concentration is at least 20.6 %.
If actual CO2 values are higher or O2
values are lower, then pressure test
the flue pipe with a static pressure of
200 Pa.
Draining the heating system

Please note
Risk of scalding

when the boiler water tempera-
