14.1.4 Check system pressure
The water pressure in the heating system can be read
on the pressure gauge. As a rule of thumb (for buil-
dings of up to three storeys), the pressure should be 1
to 2 bar for a cold system and 1.5 to 2.5 bar for a hot
system.
It is important that the pressure remains constant at all
times. A constant fall in pressure requires the addition
of extra water and indicates a fault in the system (e.g.
a leak).
i
TIP: Make a note of the set system pressure
during initial commissioning.
14.1.5 Clean exhaust gas duct
The flue pipe is located between boiler and chimney.
►
Remove cover

in the flue gas pipe.
►
Remove combustion deposits (e.g. dust, fly ash)
from the pipe.
14.1.6 Check safety valve
Carry out a visual check for leaks at the valve (inspect
around outlet of dump hose). Turning the valve cap is
not recommended, as the valve may not seal com-
pletely afterwards.

14.1.7 Replace pellet suction turbine
The suction turbine for conveying the pellets is a wea-
ring part. Depending on the degree of soiling
[1]
of the
suction turbine, the service life of the suction motor car-
bon brushes is around 300 operating hours for the
initial equipment, and another 300 operating hours for
the replacement carbon brush set. After approx. 800
operating hours, we recommend replacing the suction
turbine.
[1] The cleaner the working air (air in the pellet hose) and cooling
air (ambient air sucked in from the room), the longer the service
life of the brushes will be.
14.1.8 Maintenance by qualified personnel
Depending on the operating hours (in each case after
1800 hours, fixed value) or a defined duration (in
months), the control shows an indication of the ne-
cessary professional maintenance of the boiler.
