11.
When heating the system from cold
(also when restarting after mainte-
nance and cleaning work), prevent
any heat supply to the heat consum-
ers in order to clear the dew point
range as quickly as possible.
!
Please note
During boiler heat-up,
unpleasant fumes and
odours can result from gases
being expelled from the ther-
mal insulation, the heating
block and the paint.
Vent the room during com-
missioning.
12.
After the flow temperature has been
reached, switch ON the heat con-
sumers in sequence and change the
burner over to automatic mode.
!
Please note
When testing the flue gas for
CO, internal gases being
expelled from the heating
block can cause higher val-
ues.
Continue to operate the
boiler until a decline can be
clearly recognised.
