6 Starting Up The Heating System; 6.1 Bringing The System Up To Operating - Buderus Logano GB125 BE Installation And Maintenance Instructions Manual

6 Starting up the heating system
This section describes the initial start-up procedure
regardless of the installed control panel.
B Complete the commissioning report during this
process ( Chapter 6.9, page 35).
Additional information on boiler room conditions and
requirements, combustion air supply and flue systems and
boiler operation can be found in Chapter 2.9, page 9.
WARNING: Risk of boiler damage from
excessive dust and air contamination!
B Do not operate the boiler when there is
potential for a lot of dust being drawn into
the combustion air supply.
B Install 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.
6.1 Bringing the system up to operating pressure
Bring the system up to the normal operating pressure
before commissioning.
CAUTION: Risk of damage to system due to
material stress caused by temperature
differentials!
B Only fill the heating system when cold (the
flow temperature should be no more than
100 °F).
B 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
positive pressure (depending on safety valve installed).
WARNING: Health risk from contaminated
domestic water!
B Observe all national standards and
regulations regarding prevention of
domestic water contamination (e.g. by
water from heating systems).
B Bleed the heating system while filling.
