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 regula­tions relating to oil and combustion.
Only oil suitable for the burner should
be used and then in combination with

a suitable oil lter before the oil pump

of the burner.
If the burner is replacing an existing

burner make sure that the oil lter is

replaced or cleaned. The installation
must only be undertaken by expe­rienced 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 ac­company the burner and should be
left in a prominent place adjacent to
the burner.

Measures to raise the temperature:
Insulate the chimney in cold attics
Install a tube in the chimney
Install a draught regulator (dilutes the

ue gases during operation and dries

them up during standstill)
Increase the oil quantity

Raise the ue gas temperature by

removing turbulators, if any, in the
boiler.

Instructions for use

The end user of the burner should be
instructed about the operation and
safety features of the burner.
He should also be made aware of
the importance of the area around

the boiler/burner being kept free of

combustible material.

Pump adjustment

See separate description.

Adjustment of burner

To obtain a correct adjustment a

ue gas analysis and a temperature

measurement must be carried out.
Otherwise there is a risk that a bad
adjustment may cause a formation of

soot, bad efciency or condensate in

the chimney.

Maintenance

The boiler/burner should be examined

regularly for any signs of malfunction
or oil leakage.

Adjustment of nozzle assembly 0 - 22

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 boiler manufactu­rers instructions.These must include

the checking of ue gas temperatures,

average water temperature and CO2
or O2 concentration.
To adjust the combustion device,
start by increasing the air volume
somewhat.

When the burner starts it is burning

with excess air and smoke number

0. Reduce the air volume until soot
occurs and increase again to reach
a combustion free of soot.
By this procedure an optimum adjust­ment is obtained. If larger nozzles
are used the preadjustment of the air
volume must be increased.

Condensation in chimney

A modern burner works with less
excess air and often also with smal­ler nozzles than older models. This

increases the efciency but also the

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

chimney ue is too large. The tempe­rature of the ue gases should exceed

60°C measured 0,5 metres from the
chimney top.

Air adjustment 0 - 32

Suction line tables

The suction line tables consist of
theoretically calculated values where
the pipe dimensions and oil velocity
have been matched so that turbulences
will not occur.
Such turbulences 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 lter.

The sum of these individual resistances

is so insigni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
according to current standards. On
commissioning 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

5,0 kg/h and 2,15 mm2/s (cSt). Max.

permissible pressure at the suction and
pressure side is 2,0 bar.

Purging

On 1-pipe systems it is necessary to
purge the pump. On 2-pipe systems
purging is automatic through the
return line.

INSTRUCTIONS PUMP TYPE DANFOSS BFP 52E

Function danfoss BFP 52E

When the oil pump is started, oil is

drawn from the suction connection

(S) through the lter (H) to the gear

wheel (C).
From here the gear wheel pumps the

oil over to the pressure side in connec­tion with the pressure regulation (P1)
and (P2).

When the oil reaches the cut-off valve

(NC), the pressure rises until regula­ting valve (P1) opens and holds the
pressure constant at the set level.

When voltage is applied to the cut-off

valve (NC) it opens and releases oil
to the nozzle (E). Surplus oil is led
through the return channel to the
return connection (R).

The pump will now run at the pressure
set for stage 1, since stage 1 is adjusted
to a lower pressure than stage 2. If
voltage is applied to the solenoid valve
(NO), it closes and sets the regulating
valve (P1) out of action. The pressure
will now rise to the setting on regulating
valve (P2).

V

G
A

R S

The valve (P2) opens and holds the
pressure constant at the set value
for stage 2. Surplus oil is led back
through the return channel to the
return connection (R). On a 2-pipe
unit the oil is led back to the oil tank.
On a 1-pipe unit the oil is recirculated
across the changeover valve (A)
through the return channel (G). The
return connection (R) is blanked off
with a plug.

When the burner stops, the voltage to

the solenoid valves is cut off so that

the NC valve closes and the NO valve

opens. The oil ow to the nozzle is cut

off by the NC valve.

How to remove cartridge lter

from plug

Unscrew the cartridge lter plug in

the cover by means of a 4 mm allen

key and withdraw the cartridge lter. If

necessary, put a screwdriver between

the cartridge lter and the plug and
turn the cartridge lter carefully until
it comes off. Reject the cartridge lter

and replace it by a new one. Press it
on to the plug. Ensure that the

O-ring is not damaged. Then t the
new cartridge lter to the pump.
