accessories
1. Check that the turbulators (if
installed) are fully pushed into the
hot gas flues (open the cleaning
door(s)).
2. Check that the installation room
ventilation is open.
3. Check the function of the water
treatment system.
4. Fill the boiler with water and venti-
late it.
Note
The water in hot water boilers
must comply with EN 12953 part
10; see also "Standard values for
water quality" on page 20.
5. Check all fitted components, such
as pipework, valves, regulators,
pumps etc. for function and leaks.
6. Check the system pressure.
7. Check the fuel oil level or the gas
supply pressure.

Commissioning, inspection, maintenance
11. Switch ON the main isolator, the
switch for the boiler drives and
the burner control switch in this
order (observe the burner manu-
facturer's operating instructions).
12. Start the boiler at a low output
(max. 30%) and gradually heat up
to a temperature of approx. 30 K
below operating temperature.
13. After the required flow tempera-
ture has been reached, gradually
open the boiler return valve and
possibly the feedwater valve as
well as the boiler flow valve.
14. Only then enable the full burner
load.
15. When heating the system from
cold (also when restarting after
maintenance and cleaning work),
prevent all heat transfer to consu-
mers, to clear the dew point range
as quickly as possible.
16. After the operating temperature
has been reached, sequentially
switch on the heat consumers and
change over to automatic mode.
