15.1.2 Check system pressure
The water pressure in the heating system can be
read on the pressure gauge. As a rule of thumb (for
buildings 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 addi-
tion 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.
15.1.3 Cleaning flue gas pipe
The flue gas pipe is located between boiler and chim-
ney.
►
Remove cover

in the flue gas pipe.
►
Remove combustion deposits (e.g. dust, flue
ash) from the pipe.
15.1.4 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.

15.1.5 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
carbon brushes is around 450 operating hours for the
initial equipment, and another 450 operating hours for
the replacement carbon brush set. After approx. 1200
operating hours, we recommend replacing the suc-
tion 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.
15.1.6 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.
