Placing the heating system in operation
This chapter describes the initial start-up procedure
regardless of the installed control device.
V
Complete the start-up protocol during this process
(
Æ
Chapter 6.9, page 37).
Further information on boiler room conditions and require-
ments, combustion air supply and flue systems and boiler
operation can be found in Chapter 2.7, page 11.
6.1
Bringing the system up to operating pressure
Bring the system up to the normal operating pressure
before commissioning.
V
Top up the heating water or drain via the boiler fill and
drain valve until the required operating pressure has
been reached: minimum 15 psi, maximum 30 psi posi-
tive pressure (depending on safety valve fitted).
V
Bleed the heating system while filling.

ating pressure and supply temperature
Warning:
Risk of boiler damage from exces-
sive dust and air contamination.
V
Do not operate the boiler when there is
potential for a lot of dust being drawn into
the combustion air supply.
V
Fit an air filter if the supply of combustion
air contains large quantities of dust (e.g.
from unpaved roads and tracks or dusty
workplaces such as quarries, mines, etc.)
or airborne particles.
Caution:
Risk of damage to system due to
material stress caused by temperature differ-
entials.
V
Only fill the heating system when cold (the
flow temperature should be no more than
100 °F).
Warning:
Health risk from contaminated do-
mestic water.
V
Observe all national standards and regula-
tions regarding prevention of domestic
water contamination (e.g. by water from
heating systems).
