Trouble
Possible reason
Solving method
Burner does not start after
start-up or works
inconsistently giving out an
error
Primary air pressure in line 1
is set beyond recommended
value.
Regulate primary air pressure value according to
section 7.
Fuel does not heat up to
necessary temperature.
Increase fuel heating temperature value according
to section 8.
There is too much moisture in
the fuel.
Let the fuel stand before use. Adjust the floating fuel
inlet according to section 11.
There are mud or solid dregs
in the fuel.
Replace the filtering element according to section

oil in the fuel.
Add some mineral oil into the fuel. It should be 30%
fuel, 70% mineral oil.
or
Add 10-20% of diesel to the fuel volume.
Fuel does not ignite properly.
Check the fuel. Replace it or add diesel. Combine
proportion experimentally.
Littered sieving filter in the
preliminary fuel heating box.
Clean the filter. Replace the filtering element of the
lifting unit. Clean the heater box from dregs and
soot.
Moisture in the preliminary
heating box.
Pour moisture out via drain tap 17 (pic.3). Adjust a
floating fuel inlet according to section 11.
Littered nozzles.
Use an authorized service center NORTEC to clean
the nozzles.

Release and work on the float. Clean the box from
dregs and resin.
The lifting unit and burner are
too far from each other.
Move the fuel box closer to the burner or set up
another box next to the burner. Make the fuel line
cross section bigger.
Fuel flows out via the drain
hole of the heater box
Fuel is heated up too much.
Turn down the temperature of fuel heating
according to section 8.
