General

General rules

This is a burner designed for FAME (RME) fuel. The fuel must meet the

requirements of standard EN 14214 for FAME. The equipment on the burner

is, however, of such a quality that it is possible to use EO1 type oil without

modiﬁcation, although with appropriate adjustments to the combustion

values after each change of fuel type.

Firing with EO1 should be conducted the last few hours at the end of the

ﬁring season.

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

regulations relating to oil and combustion.

Only oil suitable for the burner must be used and then in combination with a

suitable oil ﬁlter designed for FAME (RME) and installed before the burner’s oil

pump.

If the burner is replacing an existing burner, ensure that the oil ﬁlter is

changed to a ﬁlter designed for FAME (RME). Installation may only be

performed by qualiﬁed 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.

Burners which are fuelled by FAME (RME) are and must be equipped with

parts designed for this fuel. This applies in particular to oil-related parts such

as the pump, solenoid valve, oil ﬁlter and hoses. It is very important when

carrying out a service to replace old parts with new parts of the same quality.

1.1 Manual

• The contents of this manual are to be observed by all who work for any

reason on the unit and its appertaining system parts.

• This manual is intended especially for authorised personnel.

• This manual is to be regarded as part of the burner and shall always be

available near the place of installation.

1.2 Safety directions

The electrical installation shall be made according to valid regulations for

heavy current and in a professional way, so that the risk of leaking oil, ﬁre or

personal injury is avoided.

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.

1. GENERAL INSTRUCTIONS

Bentone B45-2 RME

General

Adjustment of burner

The burner is from the factory preset to an average value

that must then be adjusted to the boiler in question.

All burner adjustments must be made in accordance with

boiler manufacturers instructions.These must include

the checking of ﬂue gas temperatures, average water

temperature and CO2 or O2 concentration.

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 disappear again. Then the volume of air is

reduced until soot occurs and increased again to reach a

combustion free of soot.

By this procedure an optimum adjustment 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

assembly adjustment somewhat. The CO2-content and

consequently the air volume will then be reduced.

Condensation in chimney

A modern burner works with less excess air and often

also with smaller nozzles than older models. This

increases the efﬁciency but also the risk of condensation

in the chimney. The risk increases if the area of the

chimney ﬂue is too large. The temperature of the ﬂue

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 ﬂue gases

during operation and dries them up during

standstill)

• Increase the oil quantity

• Raise the ﬂue gas temperature by removing

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. Any boiler/burner that

uses FAME (RME) as fuel must be serviced at least twice

a year.

Firing with EO1 should be conducted the last few hours

at the end of the ﬁring season.

Installation instructions

General installation instructions accompany the burner

and should be left in a prominent place adjacent to the

burner.

Oil supply

The oil line should be dimensioned in accordance with

the pump manufacturer´s instruction. A ﬁlter designed for

FAME (RME) that prevents any particles in the oil from

reaching the burner is mounted in the burner’s suction

pipe. If the installation consists of several burners each

one should have its own suction line from the tank or a

circulation 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.

The oil pipe and electric cable should be ﬁtted so that

the burner can be placed on the ﬂoor for inspection of

the combustion device.

Oil hoses must be of a quality designed for FAME (RME).

Pump pressure 14 bar (8-28 bar)1) !The burner pump is factory set at 14 bar and

test operated using Roadway 80.

Because of the various boiler types with varying furnace geometries and

furnace loads, it is impossible to commit to a certain scattering angle or a

speciﬁc distribution pattern.

It should be noted that the scattering angle and distribution pattern changes

with pump pressure.
