GENERAL INSTRUCTIONS

General rules

The installation of an oil burner should

be carried out in accordance with local

regulations. The installer of the burner

must therefore be aware of all regula-

tions relating to oil and combustion.

Only oil suitable for the burner should

be used and then in combination with

a suitable oil ﬁ lter before the oil pump

of the burner.

If the burner is replacing an existing

burner make sure that the oil ﬁ lter is

replaced or cleaned. The installation

must only be undertaken by expe-

rienced personnel. Care should be

taken by the installer to ensure that no

electrical cables or fuel/gas pipes are

trapped or damaged during installation

or service/maintenance.

Installation instructions

General installation instructions ac-

company the burner and should be

left in a prominent place adjacent to

the burner.

Adjustment of burner

The burner is from the factory pre-set

to an average value that must then

be adjusted to the boiler in question.

All burner adjustments must be

made in accordance with the boiler

manufacturer´s instructions.These

must include the checking of ﬂ ue gas

temperatures, average water tem-

perature and CO2or O2concentration.

To adjust the combustion device, start

by increasing the air volume and the

nozzle assembly somewhat.When the

burner starts it is burning with excess

air and smoke number 0. Reduce the

nozzle assembly adjustment until

soot occurs, and then increase the

adjustment to make the soot disap-

pear again. Then the volume of air

is reduced until soot occurs and in-

creased again to reach a combustion

free of soot.

By this procedure an optimum adjust-

ment is obtained. If larger nozzles are

used the preadjustment of both the

air volume and the nozzle assembly

must be increased.

A whistling sound may be heard

which can be eliminated or reduced

as follows: Increase the nozzle as-

sembly adjustment somewhat. The

CO2-content and consequently the air

volume will then be reduced.

Oil supply

The oil line should be dimensioned

in accordance with the pump

manufacturer´s instruction. In the

suction line to the burner a ﬁ lter should

be mounted to prevent any particles

in the oil from reaching the burner.

If the installation consists of several

burners each one should have its own

suction line from the tank or a circula-

tion system should be used.

The temperature in the oil line should

be kept as constant as possible.Avoid

exposing the line to excessive cold

which may cause blockages of parafﬁ n

deposits.

The oil pipe and electric cable should

be ﬁ tted so that the burner can be

placed on the ﬂ oor for inspection of

the combustion device.

Condensation in chimney

A modern burner works with less ex-

cess air and often also with smaller

nozzles than older models. This

increases the efﬁ ciency but also the

risk of condensation in the chimney.

The risk increases if the area of the

chimney ﬂ ue is too large. The tempera-

ture of the ﬂ ue gases should exceed

60°C measured 0,5 metres from the

chimney top.

Measures to raise the temperature:

Insulate the chimney in cold attics

Install a tube in the chimney

Install a draught regulator (dilutes the

ﬂ ue gases during operation and dries

them up during standstill)

Increase the oil quantity

Raise the ﬂ ue gas temperature by re-

moving turbulators, if any, in the boiler.

Pump adjustment

See separate description.

Maintenance

The boiler/burner should be examined

regularly for any signs of malfunction

or oil leakage.

Function

1. Switch on operating switch and twin thermostat

The burner motor starts, an ignition spark is formed, the prepurge goes

on till the prepurge period expires and the solenoid valve 1 opens (2).

2. Solenoid valve 1 opens

Oil mist is formed and ignited. The photocell indicates a ﬂ ame.

3. The safety time expires

a. If no ﬂ ame is established before this time limit the control cuts out.

b. If for some reasons the ﬂ ame disappears after this time limit, the burner

will make an attempt to re-start.

4. Full load thermostat ON

The burner is in operating position and can now change between high

and low capacity.

4-5. Operating position

If the burner operation is interrupted by means of the main switch or the

thermostat, a new start takes place when the conditions in accordance

with point 1 are fulﬁ lled.

The oil burner control cuts out

A red lamp in the control is lit. Press the reset button and the burner

re-starts.

the normal sequence, as well as provide indication if something ab-

normal is happening in accordance with the following table:

Preheater in operation Solid yellow

Ignition switched on Flashing yellow

Normal operation Solid green

Operation, poor ﬂ ame signal Flashing green

information about what has caused the problem by pressing and

holding the reset button for 3 seconds.

The number of ﬂ ashes below is repeated with a pause in between.

2 ﬂ ashes No ﬂ ame signal when safety time

expires

4 ﬂ ashes False light during start

7 ﬂ ashes 3 x Losses of ﬂ ame during operation

8 ﬂ ashes Time-out for preheater *

10 ﬂ ashes Incorrect wiring, internal fault or si-

multaneous occurrence of two faults

* In order for this fault code to occur, the preheater shall not reach

its cut-off temperature within 10 mins. from switch on.

To return to normal operation: Press the reset button for 1 second.

If the reset button is instead kept pressed a second time for at least

3 seconds, you can, via an interface, obtain the corresponding in-

formation on a computer or ﬂ ue gas analyser.

Suction line tables

The suction line tables consist of theo-

retically calculated values where the

pipe dimensions and oil velocity have

been matched so that tur-bulences will

not occur. Such tur-bulences will result

in increased pressure losses and in

acoustic noise in the pipe system. In

addition to drawn copper piping a pipe

system usually comprises 4 elbows, a

non-return valve, a cut-off valve and

an external oil ﬁ lter.

The sum of these individual resi-

stances is so insigniﬁ cant that they

can be disregarded. The tables do not

include any lengths exceeding 100

m as experience shows that longer

lengths are not needed.

The tables apply to a standard fuel

oil of normal commercial quality

accor-ding to current standards. On

commis- sioning with an empty tube

system the oil pump should not be

run without oil for more than 5 min.

(a condition is that the pump is being

lubricated during operation).

The tables state the total suction line

length in metres at a nozzle capacity

of 9,5 Gph. Max. permissible pres-

sure at the suction and pressure side

is 2,0 bar.

INSTRUCTIONS PUMP TYPE SUNTEC A2L 65C - 75C

Pump operating principle for

A2L 65C - 75C

The SUNTEC A2L oil pump has two

nozzle outlets. It incorporates two

blocking solenoid valves with in-line-

cut-off function, one for each nozzle

outlet.

The gear set draws oil from the tank

through the built-in ﬁ lter and transfers

it to the nozzle line via the cut-off so-

lenoid valves. A pressure regulating

valve is used to dump all oil which is

not required at the nozzle.

In one-pipe operation, the oil which

does not go through the nozzle lines is

returned directly to the gear inlet and

the suction line ﬂ ow is equal to the

sum of the 2 nozzle ﬂ ows. In two-pipe

operation, the by-pass plug must be

ﬁ tted in the return port, which ensures

that the oil dumped by the regulating

valve is returned to the tank and the

suction line ﬂ ow is equal to the gear

set capacity.

Bleed

Bleeding in two-pipe operation is au-

tomatic: it is assured by a bleed ﬂ at

on the piston. In one-pipe operation,

a high pressure connection must be

loosened until the air is evacuated

from the system.

Cut-Off

The solenoid valves of the A2L pump

are of the "normally closed" type and

are situated in the nozzle lines. This

design ensures extremely fast res-

ponse and the switching can be sel-

ected according to the burner opera-

ting sequence and is independant of

motor speed.

When the solenoids are non-activated,

the valves are closed and all oil

pressurised by the gear set passes

through the regulator to suction or to

the return line, depending upon pipe

arrangement.

As soon as the solenoids are activat-

ed, oil passes to the nozzle lines at

the pressure set by the pressure

regulating valve.
