This chapter details the commissioning process, inde-
pendently of the type of control unit used.
B
Complete the commissioning report during commis-
sioning (
8.1
Creating operating pressure
Create the operating pressure required before commis-
sioning.
B
Set the red pressure gauge indicator to the required
operating pressure of at least 1 bar (applies to sealed
unvented systems).
B
Top up the heating water or drain via the boiler drain
& fill valve until the required operating pressure has
been reached.
B
Vent the heating system while filling.
BOILER DAMAGE
through excessive dust and airborne seed.
B
Never operate the boiler when there is

Install an air filter if the combustion air
supply is very dusty (e.g. due to dirt
roads and paths or dust-generating
working environments such as quar-
ries, mines etc.) or contains airborne
seeds from composite plants.
