MAINTENANCE

Before cleaning or performing checks, switch off the burner's power supply with the system's master
switch and close the gas shutoff valve.
The burner requires periodic maintenance carried out by a qualified and authorised technician in conformity
with legislation and local standards.
Scheduled maintenance is vital for the smooth operation of the burner; it avoids waste of fuel and reduces pol-
lutant emissions into the atmosphere.
FUNDAMENTAL OPERATIONS TO BE CARRIED OUT ARE AS FOLLOWS:
Make sure the air intake areas and ducts taking the flue gases away do not feature any obstructions or
restrictions.
Electrical wiring
Check that the burner and gas train electrical connections are correct.
Gas leaks
Make sure there are no gas leaks in the following areas:
- on the meter-burner pipework
- on the mixer/valve connection
- on the burner fastening flange where the seal is fitted.
Combustion head
Inspect the combustion head and make sure the fabric is undamaged and does not features large or
deep holes or corroded areas. Also make sure that no parts have warped as a result of high
temperature.
Electrode unit
Make sure neither the electrodes nor probe feature marked warping or oxidation on surfaces. Make sure
distances are still in line with those indicated in fig. 4, readjusting to the right values where necessary.
Where necessary, remove oxide from the surface of the probe with abrasive paper.
