13 Flue gas test
The flue gas test must only be carried out by a heating
contractor. It is carried out once a year during the annual
service.
The individual heating zones then pass their maximum
possible demand to the boiler. With the pumps switched
off, the boiler is brought as rapidly as possible to the
supply temperature required for the tests (current boiler
water temperature shown in display) and attempts are
then made to maintain this temperature without turning
the burner off while switching on additional consumers.
This has the effect of extending the test periods as long
as possible.
The ON/OFF switch on the control device must be ON.
"BRNR TEST" and the boiler water temperature appear
in the display.
After 30 minutes the control device reverts automatically
to the mode it was in prior to the test.
