Notes on safety for the maintenance

The periodic maintenance is essential for the good operation,
safety, yield and duration of the burner.
It allows you to reduce consumption and polluting emissions
and to keep the product in a reliable state over time.
The maintenance interventions and the calibra-
tion of the burner must only be carried out by
qualified, authorised personnel, in accordance
DANGER
with the contents of this manual and in compli-
ance with the standards and regulations of cur-
rent laws.

Maintenance programme

Maintenance frequency

The gas combustion system should be checked at least once
a year by a representative of the Manufacturer or another
specialised technician.
Checking and cleaning
Combustion
Carry out an analysis of the flue gases. Significant differences
with respect to the previous measurements indicate the points
where more care should be exercised during maintenance.
Gas leaks
Make sure that there are no gas leaks on the pipes between
the gas meter and the burner.
Gas filter
Replace the gas filter when it is dirty.
Flame inspection window
Clean the glass of the flame inspection window, (Fig. 37).

Before carrying out any maintenance, cleaning or checking op-
erations:
disconnect the electricity supply from the burner
by means of the main switch of the system;
DANGER
close the fuel interception tap;
DANGER
Combustion head
Open the burner and make sure that all the components of
the combustion head are:
- undamaged;
- not deformed due to high temperature;
- free of ambient dirt or dust;
- free of rusted materials;
- adequately positioned.
Make sure that the gas outlet holes for the start-up, on the
combustion head distributor, are free of dirt or rust deposits.
If in doubt, disassemble the elbow 5)(Fig. 38).
Servomotor
Disengage cam 4)(Fig. 28) from the servomotor, by pressing
and shifting button 3)(Fig. 29) to the right, and cause it to turn
it backwards and forwards by hand to make sure it moves
smoothly. Now engage the cam again by shifting button
2)(Fig. 28) to the left.
Burner
Check for excess wear or loose screws in the mechanisms
controlling the air damper and the gas butterfly valve. Also
make sure that the screws securing the electrical leads in the
burner connections are fully tightened.
Clean the outside of the burner, taking special care with the
articulated couplings and cam 4)(Fig. 28).
Combustion
Adjust the burner if the combustion values found at the begin-
ning of the operation do not comply with the regulations in
force or, at any rate, do not produce good combustion.
Use the appropriate card to record the new combustion val-
ues; they will be useful for subsequent controls.
