Commissioning the heating system
This chapter details the commissioning independent of
the installed control unit.
V
Complete the commissioning report during the
commissioning procedure (
Æ
Chapter 7.8, page 49).
For further information on boiler room conditions and
requirements, combustion air supply and flue systems,
and boiler operation, see Chapter 2.10.1, page 10 to
Chapter 2.10.6, page 13.
7.1
Bringing the system up to operating pressure
Bring the system up to the standard operating pressure
before commissioning.
V
Adjust the red pointer [1] of the pressure gauge to the
required operating pressure of at least 1 bar (applies to
sealed unvented systems).
V
Replenish the heating water or drain via the boiler fill &
drain valve until the required operating pressure is
obtained (
Æ
Chapter 6.3, page 41).
V
Vent the heating system during filling.

Warning: Risk of boiler damage from
excessive dust and airborne seed levels.
V
Never operate the boiler when there is a
lot of dust in the boiler room, e.g. due to
building work.
V
Fit an air filter if the supply of combustion
air contains large amounts of dust (e.g.
from unsurfaced roads and tracks or dusty
workplaces such as quarries, mines, etc.)
or airborne seeds from plants of the
Asteraceae family.
Caution: Risk of damage to system due to
material stresses caused by temperature
differentials.
V
Only fill the heating system when cold
(the flow temperature should not exceed
40 °C).
Danger: Health risk from contaminated
domestic water.
V
Observe all national standards and
regulations regarding prevention of
domestic water contamination (e.g. by
water from heating systems).
