Maintenance
Combustion head
Open the burner and make sure that all components of the
combustion head are in good condition, not deformed by the
high temperatures, free of impurities from the surroundings
and correctly positioned.
If in doubt, disassemble the elbow 5)(Fig. 38).
Gas filter
Change the gas filter when it is dirty.
Flame inspection window
Clean the glass of the flame inspection window (Fig. 39).
Combustion
Carry out an analysis of the combustion flue gases.
Significant differences with respect to the previous
measurements indicate the points where most care should be
exercised during maintenance.
If the combustion values measured before starting maintenance
do not comply with applicable Standards or do not indicate
efficient combustion, consult the Tab. H or contact our Technical
Support Service to implement the necessary adjustments.
It is advisable to set the burner according to the type of gas used
and following the indications in Tab. H.
