Secondary air cleaning
Attention!!! During cleaning disconnect the boiler from power supply!
Step 1:
Unplug fan and flap servo-unit connectors
Step 2:
Under the fan plate
disassembly (see chap 15.4 for assembly)
Step 3:
Use vacuum to hoover secondary air pipes and check cleanliness.
Clean ways of air pipe system is the basic condition to achieve correct boiler burning process. If often used
sawdust as fuel, must be cleaned minimum one time in the season. The system is built form primary and
secondary air trunks. The boiler construction allows with advanced parts disassembly offer areas to clean.
When fan cover removed (8) pic.3
access to fan is free.
To clean air pipe system do as follows:

When line connecter plugged in, the power supply servo-unit will start automatic initialization, which is
also shown on the display. During this initialization servo-unit is pushed.
The position of secondary air flaps can considerably affect quality of
burning. VIGAS
Lambda Control
boilers control amount of secondary air
automatically. This option provides optimum conditions for burning of
all wood types.
In VIGAS boilers without lambda sensor is the mixture
of primary and secondary air firmly adjusted by screws „1“. Optimum
adjustment of secondary air screws „1“ is 2,5 turn from manufacturer.
To change or control position do as follows:
Step 1:
loose safety bolt nut on the screw „1“,
Step 2:
drive screw „1“ in towards boiler all the way,
Step 3:
then, adjust by 2,5 turn (optimum),
Step 4:
tighten safety bolt nut.
Boilers without lambda sensor are equipped with safety flap (above
fan) „2“ which stops burning of the boiler without fan (only chimney
draught). In case, boiler does not have sufficient output, check this
flap function.

Lambda sensor and exhaust gas thermometer must be clean to
function properly. When cleaning exchanger always gently wipe out
dust from lambda sensor „1“ and exhaust gas thermometer „2“.
Important: Thermomether must be in accurate position. Its metal
insert must be samle level asits bipod sleeve.
(By changing
position of thermometer the temperature will considerably change.)
Connect lambda sensor and exhaust gas thermometer to „3“ a „4“
box.
