12 System start-up
You can connect series 4000 control devices to
Logano GE515 boilers. These control devices are
commissioned through identical steps.
BOILER DAMAGE
through heavy dust deposits.
CAUTION!
Do not operate the boiler where heavy
dust contamination persists, e.g.
through building work inside the boiler
room.
Complete the commissioning report (
"Commissioning report", page 54).

12.1 Filling the system

SYSTEM DAMAGE
through temperature stresses.
CAUTION!
Fill the heating system only via the fill
cock in the pipework (return) of the
heating system.
Observe the following table regarding the appropriate
use and preparation of the fill and make-up water.
This table is an extract from the Code of Practice K8
"Water treatment for hot water heating systems" in the
Buderus sales catalogue.
The ph value of the heating water increases after the
system has been filled. Check after the first three to six
months (during the first maintenance), whether the ph
value of the heating water has settled down.
