Wet Cleaning (Chemical Cleaning); Checking The Operating Pressure - Buderus Logano GE615 Installation And Maintenance Instructions Manual

z Clean hot gas baffles with the cleaning brushes.
V Insert hot gas baffles into hot gas flues (Æ Fig. 30,
page 25 and Fig. 31 and Fig. 32, page 26).
z Seal clean-out covers and burner door. Tighten screws
evenly. Hook the front side panels back in place. Put

under the flue outlet using tension springs.
z Put the lower boiler panel back in place.
7.3.2

Wet cleaning (chemical cleaning)

When wet cleaning, use a cleaning agent commensurate
with the degree of soiling (encrustations or soot).
Proceed in the same sequence as if cleaning with clean-
ing brushes (Æ see section 7.3.1, Seite 47).
Follow the cleaning agent and cleaning
equipment instructions.
In some circumstances you may need to
proceed differently from the method
described here.
z Cover the control panel with plastic to prevent the
ingress of spray.
z Spray cleaning agent evenly into the hot gas flues.
z Close burner door and start the heating system.
z Heat the boiler water temperature to at least 70 °C.
z Shut down the boiler.
z Allow boiler to cool, open burner door.
z Brush out the hot gas flues.

Heating system inspection and maintenance
7.4

Checking the operating pressure

A distinction is generally made between open and sealed
systems. In practice, open heating systems are seldom
installed.
For information on the quality of the heating
water (Æ see operator's log).
Caution: System damage
Depending on water quality, the heating
system may be damaged by corrosion or
scaling if you frequently top-up the heating
water.
z Vent the heating system.
z Check the heating system for leaks and
the expansion vessel for proper
functioning.
z If water loss occurs frequently, locate the
cause and rectify the problem without
delay.
Caution: System damage
through temperature stresses
Temperature stresses can cause cracks if
you fill your heating system when hot. This
will cause the boiler to leak.
z Only fill the system when cold (the flow
temperature should be no more than
40 °C).
z During operation, only fill the heating
system via an approved WRAS method.
