It is necessary that the insulating gasket

(9, fig. 1) is placed between the boiler door

and the burner flange.

This insulating gasket has six holes,

which, if necessary, can be modified as

shown on the drawing on the right.

Verify that the installed

burner is lightly leaned

towards the button.

(See figure 2).

HYDRAULIC SYSTEM

Warning:

before starting the burner make sure that the return pipe-line is not clogged: any obstruc-

tion would cause the pump seals to break.

The pump vacuum should not exceed a

maximum of 0.4 bar (30 cm Hg).

Beyond this limit gas is released from

the oil.

Oil lines must be completely air-

tight.

The return line should terminate in

the oil tank at the same level as the

suction line; in this case a non-return

valve is not required.

When the return line arrives over the

fuel level, a non-return valve must be

used.

This solution however is less safe than

previous one, due to the possibility of

leakage of the valve.

PRIMINGTHE PUMP

Start the burner and wait for the priming.

Should lock-out occur prior to the arrival

of the fuel, await at least 20 seconds

before repeating the operation.

A filter must be installed on the suction fuel line.

NOTES

– Wires of 1 mm2section.

– The electrical wiring carried out by the

installer must be in compliance with the

rules in force in the Country.

– To remove the control-box from the

burner, loosen screw (A)

(see ﬁgure)

and

pull towards the arrow.

– The photoresistance is ﬁtted directly into the

control-box

(underneath the ignition-trans-

former)

on a plug-in support.

TESTING

Check the shut-down of the burner by opening

the thermostats.

ATTENTION

Do not connect burner’s grounding, to failure

indicator terminal .

This may result the destroy of the control box.

COMBUSTION ADJUSTMENT

In conformity with Efficiency Directive 92/42/EEC the application of the burner on the boiler, adjust-

ment and testing must be carried out observing the instruction manual of the boiler, including verifica-

tion of the CO and CO2concentration in the flue gases, their temperatures and the average

temperature of the water in the boiler.

To suit the required appliance output, fit the nozzle then adjust the pump pressure and the air damper

opening in accordance with the following schedule.

The values shown in the table are measured on a CEN boiler (as per EN 267).

They refer to 12.5% CO2at sea level and with light oil and room temperature of 20 °C.

RECOMMENDED NOZZLES: Monarch type R - NS; Delavan type W - A - E

Steinen type H - Q ; Danfoss type H - B

Angle: 60° : in most cases.

80° : in case of ﬂame detachment, during ignitions at low tem-

peratures.

PUMP PRESSURE 12 bar : the pump leaves the factory set at this value.

14 bar : improves ﬂame retention; it is therefore suitable for ignitions at

low temperatures.

COMBUSTION HEAD SETTING:This is done when ﬁtting the nozzle, with the blast tube

removed.It depends on the output of the burner and is car-

ried out by rotating the regulating rod, till the terminal plane

of the blast tube is level with the set-point, as indicated in

the schedule.

Combustion head settings indicated in the schedule are valid for most cases.

The setting of the fan output according to the installation should normally be done only through the air

damper. Should one subsequently want to retouch also the setting of the combustion head, with the

burner running, operate on the rod (1) with a 6 mm spanner (2) as follows:

Turn to the right: (sign +), in order to increase the vol-

ume of air entering the combustion chamber and thus

diminishing its pressure.

There is a reduction of CO2and the adhesion of the

ﬂame to the air diffuser disc improves.

(Setting advisable for ignitions at low temperatures).

Turn to the left: (sign –), in order to reduce the volume

of air entering the combustion chamber and thus increas-

ing its pressure. The CO2improves and the adhesion of

the ﬂame to the diffuser tends to reduce. (This setting is

not advisable for ignitions at low temperatures).

In any case do not bring the combustion head setting

more than one point away from that indicated in the

schedule. One set-point corresponds to 3 turns of the

rod; a hole (3) at its end facilitates counting the number

of turns.

AIR DAMPER ADJUSTMENT:

The regulation of the air-rate is made by adjusting the air

damper (A), after loosing the screws (B).

When the optimal regulation is reached, screw tight the

screws (B).

The settings indicated in the schedule are purely indic-

ative.

Each installation however, has its own unpredictable

working conditions: actual nozzle output; positive or

negative pressure in the combustion-chamber, the

need of excess air, etc.

All these conditions may require a different air-damper

setting.

Attention:

move the electrodes ahead.

After fastening the nozzle in posi-

tion, restore electrodes to proper

distance.

BURNER START-UP CYCLE

ADJUSTMENTS,TO AVOID FLAME - DETACHMENT, AT BURNER - IGNITION

This inconvenience can occur, when the temperature of the gas-oil decreases below +8 °C.

1) CORRECT POSITIONING OF THE ELECTRODES

2) NOZZLE: ATOMIZING CONE

Choose empt ies or semi-empt ies cones; Delavan type A - E; Steinen type H; Danfoss type H.

3) PUMP - SETTING

The pump is factory set, at a pressure of 12 bar.

When the temperature of the light oil decreases below +8 °C, increase the pressure to 14 bar.

4) COMBUSTION-HEAD SETTING

Regulate the combustion-head one set-point further ahead than indicated in the instructions.

Example:

the instructions require to set the combustion-head on set-point 2.

Instead, the setting is made on set-point 3.

5) FAN - AIR DAMPER ADJUSTMENT

Adjust the air damper of the fan, such as to obtain a smoke-number not inferior to 1.

(i.e. a combustion with the lowest possible excess-air).
