Cleaning the fan

Check to make sure that no dust has accumulated

inside the fan or on its blades, as this condition will

cause a reduction in the air flow rate and provoke

polluting combustion.

WARNING

When performing these operations, take care not

to damage the fan.

Proceed as follows:

 unscrew the screws 1)(Fig. 22) and take out the air damper

2);

 loosen the screws 3) and take out the suction inlet 4);

 clean the fan and the inside of the suction inlet, using a suit-

able brush and compressed air.

 If necessary, carefully disassemble the fan (Fig. 23).

It is essential to respect position B)(Fig. 23), indi-

cated in the table.

WARNING

When reinstalling, follow the above indications in reverse order;

put all the burner components back in their original positions.

Air damper

Inside the suction casing 2)(Fig. 22) there is a damper that opens

due to the effect of the depression generated when operating.

The device interrupts the natural flow of air from the burner to the

boiler and vice-versa during stop phases.

It is important to periodically check the device and clean if there

are accumulations of dust that can obstruct the regular opening

and closing of the damper.

Combustion

Carry out an analysis of the combustion flue gases.

Significant differences with respect to the previous measure-

ments indicate the points where most care should be exercised

during maintenance.

In case the combustion values found at the beginning of the inter-

vention do not respect the standards in force or, in any case, do

not correspond to a proper combustion, contact the Technical As-

sistant in order to carry out the necessary adjustments.

Let the burner run at full capacity for about ten minutes, setting all

the elements correctly as explained in this manual.

Then carry out the analysis of the combustion by checking:

•

Smoke temperature at the flue;

•

CO2 content (%);

•

CO content (ppm);

•

Smoke value according to opacity smokes index according to

Bacharach scale.
