MAINTENANCE

The burner requires periodic maintenance carried out by a qualified and authorised technician in conformity
with legislation and local standards.
Periodic maintenance is essential for the reliability of the burner, avoiding the excessive consumption of
fuel and consequent pollution.
Before  carrying  out  any  cleaning  or control always first switch off the electrical supply to the
burner acting on the main switch of the system.

THE BASIC CHECKS ARE:

Check that there are no obstructions or bends in the supply or return oil pipes, in the air intake pipes and the
combustion product discharge tubes.

Clean the filter in the oil suction line and in the pump.

Clean the flame sensor (see fig. 16, page 9).

Check for correct fuel consumption.

Replace the nozzle (4, fig. 17, page 11) and check the correct position of electrodes (fig. 18, page 11).

Clean the combustion head in the fuel exit area.

Leave the burner  working  without interruptions  for 10 min.  and set rightly all the components stated in
this manual. Then carry out a combustion check verifying:

Smoke temperature at the chimney;

Content of  CO

2

 ( % );

Content of CO (ppm);    

Smoke value according to opacity smokes index according to Bacharach scale.

ACCESS TO THE FAN,

 (see Fig. 20) 

IMPORTANT 

Perform  maintenance  work  only  when  strictly  nec-
essary, taking great care not to damage or unbal-
ance the fan during cleaning.

Take  careful  note  of  the  original  position  before
beginning any of these operations. 

Proceed as follows:

Unscrew  the  three  screws  (1)  and  remove  the  air
adjustment unit (2). At this point, you can clean the fan:
vacuum up any impurities, taking care they do not enter
the air circuit.

Refit  following  the  above  procedure  in  the  reverse
order, restoring the air adjustment unit (2) to its original
position and being extra careful to ensure that the O-
ring (12, fig. 6, page 3) is positioned correctly.

Tighten  the  three  screws  (1)  with  a  driving  torque  not
exceeding 0.8 Nm.
