6.9.4.2 Inspection of fume exhaust and air return ducting
Where possible, make a visual check or use dedicated tools to check the ducting.
Remove any dust building up on the end piece of the air intake.
6.9.4.3 Inspection and cleaning of the Venturi
With a paintbrush remove any dirt from the Venturi mouth, without dropping it inside the Venturi.
6.9.4.4 Inspection and cleaning of the heat exchanger and burner
Perfect combustion in the generators prevents dirt, which is normally caused by poor combustion.
We therefore recommend that the heat exchanger and the burner are not cleaned, unless in extraordinary
circumstances.
A symptom showing that dirt has built up in the heat exchanger may be a sensitive variation in the gas flow rate that
is not due to incorrect operation of the gas valve.
If the burner and/or the heat exchanger requires cleaning, all the seals installed between the burner and the heat
exchanger must be replaced.
6.9.4.5 Inspection and cleaning of condensate drip syphon
Clean the syphon once a year and check the condition of the connections.
Make sure that no traces of metal residues exist.
If metal residues have formed, the number of overhauls must be increased.
Take out the mounting screws from the cover and clean the interior of the syphon - the syphon can be washed in
running water. Then check that all ducts are unobstructed.
Check the condition of the seal. Check that the detection electrode is in good condition and then use emery paper to
grind off any oxidation from the metal part.
Fill the main tank "A" with fresh water and close the cover.
Connect the syphon back to the condensate drainage system.
6.9.4.6 Inspection of input gas pressure
Check that the input pressure into the valve matches the pressure value required for the gas type in use.
This check must be carried out with the generator ON at its max. heat output.
6.9.4.7 Inspection of flame control equipment
Keep the generator running and close the gas valve; check that it blocks and blockage alarm F10 appears on the
LCD display of the CPU board installed aboard the machine. Open the gas valve again, remove the blockage and
wait until the generator gets restarted.
