Acceptance inspection

Ensure that everything is delivered and that there is no transport damage.

If there is anything wrong with the delivery, please report it to the supplier.

Any transport damage should be reported to the forwarding company.

Preparations for installation

Ensure that the size and capacity range of the burner are suitable for the

boiler. Power data on the data plate refer to the minimum and maximum

power of the burner.

Distribution of oil

To ensure satisfactory operation it is essential that the oil distribution

system is correct. Observe the following:

- See Pump instructions for choice of tube diameter, tube length and

height difference.

If another electrical connection is used than the one recommended by

Bentone, there might be a risk of material damage or personal injury.

Choice of nozzle

See under Technical Data: Recommended nozzle and table of nozzles.

Setting of the shrouded disc and air ﬂ ow

The burner is pre-set on delivery in relation to the nozzle provided. If the

size of the nozzle is changed the burner can be initially set according

to “Basic settings”. Note that it is only a question of a basic setting that

should be trimmed when the burner is started. This should include a

Setting the ignition electrodes

Proper setting of the electrodes is essential to ensure satisfactory opera-

will occur. Since the electrode pack is of the factory-set twin electrode

type it will be necessary to bend the wires to make any adjustment.

Suction plate

In the case of higher power, as well as with boilers featuring overpressure

in the combustion chamber, it is possible to achieve higher fan pressure

by altering the position of the suction plate, see illustration. The plate is

located beneath the outer half of the fan housing, see illustration, Clea-

ning the fan wheel.

Position 1 is normally used for nozzles up to 0.60 gph and position 4 for

larger nozzles. Position 2 and 3 are intermediate positions. Position 5

and higher does not give more pressure and they are not used.

Check that the plate is placed in the correct position. Otherwise the air-

cannot be adjusted to the correct value.

Cleaning the fan wheel

Unscrew the four fastening screws. Remove the half of the fan housing.

Check the position of the suction plate (position 1 up to and including

0.60 gph nozzle). Remove the suction plate. Inspect and clean the fan if
