Filters

Check the filtering baskets on line and at nozzle present in the

system. Clean or replace if necessary.

If rust or other impurities are observed inside the pump, use a

separate pump to lift any water and other impurities that may

have deposited on the bottom of the tank.

Pump

The delivery pressure must be stable. The depression must be

less than 0.4 bar. Unusual noise must not be evident during pump

operation.

If the pressure is found to be unstable or if the pump runs noisily,

the flexible hose must be detached from the line filter and the fuel

must be sucked from a tank located near the burner. This meas-

ure permits the cause of the anomaly to be traced to either the

suction piping or the pump.

If the pump is found to be responsible, check to make sure that

the filter is not dirty. The vacuometer is installed upstream from

the filter and consequently will not indicate whether the filter is

clogged or not. Contrarily, if the problem lies in the suction line,

check to make sure that the filter is clean and that air is not enter-

ing the piping.

Please check that the supply line and filters are clear. The use of

a pump vacuum gauge will assist in this. This measure permits

the cause of the anomaly to be traced to either the suction line or

the pump.

If the problem lies in the suction line, check to make sure that the

filter is clean and that air is not entering the piping.

Hoses

 Check periodically the flexible pipes conditions. They have

to be replaced at least every 2 years.

 In case of use of gas oil and bio fuel blends, it is strongly rec-

ommended to inspect even more frequently the hoses and

replace them where contamination has occurred.

 Check to make sure that the hoses are still in good condi-

tion.

Nozzles

Do not clean the nozzle openings; do not even open them.

The nozzle filters however may be cleaned or replaced as re-

quired. It is advisable to replace nozzles every year during regu-

Opening the burner

Disconnect the electrical supply from the

burner.

DANGER

 Loosen screws 1)(Fig. 37) and withdraw the cover 2).

 Unscrew screws 3).

 Fit the two extensions 4) supplied with the burner onto the

slide bars 5) (models with 385 mm blast tube).

 Pull part A backward keeping it slightly raised to avoid dam-

aging the disk 6) on blast tube 7).

Closing the burner

Refit following the steps described but in reverse order; refit all

burner components as they were originally assembled.

Maintenance

lar maintenance operations. Combustion must be checked after

the nozzles have been changed.

Fuel tank

If water or contamination is present within the fuel tank, it is es-

sential that this is removed before the equipment is to be used.

This is extremely important when gas oil containing Bio diesel is

in use. If in doubt about how to achieve this then please contact

the fuel or oil tank supplier.

Combustion

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

Assistant and have him carry out the necessary adjustments.
