GENERAL RULES
Theinstallationofanoilburnershould
be carried out in accordance with
local regulations. The installer of the
burner must therefore be aware of all
regulations relating to oil and combu-
stion.
Onlyoilsuitable for the burner should
beusedand then in combinationwith
asuitable oil filter beforethe oil pump
of the burner.
If the burner is replacing an existing
burner make sure that the oil filter is
replaced or cleaned. The installation
mustonlybeundertakenbyexperien-
ced personnel.
INSTALLATION INSTRUCTIONS
General installation instructions ac-
company the burner and should be
left in a prominent place adjacent to
the burner.
ADJUSTMENT OF BURNER
Theburnerisfromthe factory pre-set

adjustedto the boiler in question.
Allburneradjustmentsmustbemadein
accordancewithboilermanufacturers
instructions.These must include the
checking of flue gas temperatures,
averagewatertemperatureandCO2or
O2concentration.
Toadjustthecombustiondevice,start
by increasing the air volume and the

CONDENSATION IN CHIMNEY
A modern burner works with less ex-
cess air and often also with smaller
nozzles than older models. This
increases the efficiency but also the
risk of condensation in the chimney.
GENERAL INSTRUCTIONS
MAINTENANCE
Theboiler/burnershouldbeexamined
regularlyforanysignsofmalfunctionor
oilleakage
OILSUPPLY
The oil line should be dimensioned in
accordance with the pump
manufacturer´s instruction. In the
suctionlinetotheburnerafiltershould
be mounted to prevent any particles
in the oil from reaching the burner. If
the installation consists of several
burnerseachoneshouldhaveitsown
suction line from the tank or a
circulation system should be used.
The temperature in the oil line should
bekeptasconstantaspossible.Avoid
exposing the line to excessive cold
whichmaycauseblockagesofparaf-
fin deposits.
The oil pipe and electric cable should
be fitted so that the burner can be
placed on the floor for inspection of
thecombustiondevice.

ture of the flue gases should exceed

chimney top.
Measurestoraise the temperature:
Insulate the chimney in cold attics
Install a tube in the chimney

Raise the flue gas temperature by

boiler.

MAINTENANCE OF OIL BURNER
SERVICE OF BURNER HEAD
Warning: Before doing any service switch off power at the main switch and cut off the oil supply.

FUNCTION
1. Operating switch ON, twin thermostat ON Air damper closed
Theburnermotorstarts.
2. Ignitionsparkisformed
Ignition spark is formed. Air damper motor opens the damper to stage
3.
3. Airdamper motor closes
The air damper motor closes to stage 1.
4. Solenoidvalve1opens
The oil mist is ignited. The photoresistor indicates a flame.
5. Thesafetytimeexpires
a. If there is no flame established before this time limit the burner
control locks out.
b. If the flame for some reason disappears after this time limit the
burner control also locks out. If a repetition of the start-up sequence
is desired, the wire link marked "Repetition" on the side of the base
plateofthecontrolmustberemoved.
6. Thermostat and switch Stage 2 ON
Theburnercan now changeovertostage2.
7. Thermostat and switch Stage 3 ON
Theburnercan now changeovertostage3.
8-9. Operatingposition
Theburnercan now changebetweenstage1,2and3. The burner
operation is interrupted by means of the operating switch or the
thermostat.
The control locks out
A red lamp in the control is lit. Move the transparent cover aside and
restart the burner by pressing the reset button.
Note!Inthe window of thecontrolsymbols appear showing inwhich
position the control locks out , see the adjoining explanation.

SUCTION LINE TABLES
The suction line tables consist of
theoretically calculated values where
the pipe dimensions and oil velocity
havebeenmatchedsothatturbulences
will not occur. Such turbulences will
resultinincreasedpressurelossesand
inacousticnoisein the pipe system. In
addition to drawn copper piping a pipe
system usually comprises 4 elbows, a
non-returnvalve,acut-offvalveandan
external oil filter.
Thesumoftheseindividualresistances
is so insignificant that they can be
disregarded.Thetablesdonotinclude
any lengths exceeding 100 m as
experience shows that longer lengths
are not needed.
Thetablesapplytoastandardfueloilof
normal commercial quality according
tocurrentstandards.Oncommissioning
withanemptytubesystemtheoilpump
should not be run without oil for more
than5min.(aconditionisthatthepump
is being lubricated during operation).
The tables state the total suction line
length in metres at a viscosity of
6,0 mm2/s.
