INTRODUCTION
This burners are for commercial or industrial use.
The burners should be installed by an experienced instaler specialized with the
instalation of oil-erd appliances.
If you pay attention to the following hints, you will be a part of the big circle of
satised users of: CITERM MULTIFUEL BURNERS
PRECAUTIONS
Waste oil may contain many foreign materials. Waste oil may also contain gaso-
line. Therefore, specic pecautions on the handling and storage of wastw oils
areto be observed when using, cleaning and maintailing this heater. Use a scren
in a fuunel when pouring oil into storage tank to catch foreign material, i.e.,
gasket material and sealant bers, etc.
WARNING: This appliance is not designated for use in hazardous atmos-
pheres containing chlorinated or halogennated hydrocarbons. Do not expose this
unit to rain or moisture.
These burners are designet to provide economic disposal of used oils. Used
oil is an incosistent fuel and may containwater and/or foreign materials witch
may cause the unit to shut down. Asecondary source of heat should always be
provided to the building.
WARNING: Do not attempt to burn any grade of gasoline, paint thinners,
or nonapproved uids. Adeqate ventilation must be provided in any enclosure
where storage tanks, pumpe or accessories are installed.
Identical to any gas or oil burning appleance, without adequate draft over the
re, thecombustion gases cannot escape the appliance. The ame will lengthen
resulting in an oveheated combustion chamber. Even if the heated is installed
correctly and adequate draft. Burnign used oil is similar to burning wood. A ne
gray ash accumulates in the chamber and ue passage. This accumulation of ash
will eventually affect the draft. It is important to remove this ash before the draft
is affected.
FUELS: CITERM burners are designed for fuels as: EL fuel oil, bio-
diesel, domestic oil, vegetable oil, wastw oils or mixtures.
WARNING: Collect and store your oil continuously and be aware that:
Water and Sludge are Not combustible !
WARNING: Faulture to provide proper venting could result in death, seri-
ous injury, and/property damage. Units must be installed with a ue connection
and a proper vent to the outside of the building. Safe operation of any oil-burn-
ing equipment requires a properly operating vent system, correct provision for
combustion air, and regular maintenance and inspection.

FUNCTION DESCRIPTION
When using synthetic oil - min. Mix it with 10% heating oilfor start safety.
When use oil from plants - set oil temperature to „max“, because ash point
is high.
When using heating oil EL – set oil temperature to „min“
HOW IT WORKS ?
Fuel is pulled from the storage tank by pump into burner tank.
A oating switch regulates the level in the burner tank.
An additional oating micro switch funcions sa a limit switch which indicates
„malfuncion“ in case of overling.
A contact switch stips the burner in case of overow in the tank.
A thermostat regulates the oil temperature in the burner tankand swiches on the
burner automatically as soon as the regulatedtemperature is reached.
An additional overheat thermostat prevents overheating with malfunctioning.
Then the burner control box (SIEMENS LOA 24) checks the procedure.
A special nozzle draws the fuel, by using the passing compressed air, which
serves as primary air for the combustion, and atomizes it.
The combustion fan delivers secondary air that is mixed with the spray mist at
the ame ring. Thereby a perfect combustion and safe operating are guaran-
tieed.
FUEL TANK
CAUTION: It is recommended that fuel be at a temperature of 50 F or
higher when it enters the pump. At a temperature below 50 F oil becomes more
viscous and difcult to pump. Supply of the burner tank may be reduced, result-
ing in nuisance shutdowns.
The storage tank should be no closer than 1,5m and no fartfer then 10m from
the burner. If the thank is lower than the boiler and is more then 5m away from
burner, then external pump must be used.
At the bottom of the supply tank manual valve must be instaled (for water and
sludge separation)
WARNING: Never install suction line at the botton of the supply tank!
Suction line must be tted at 20cm higher from bottom.

SUPPLY LINES
Read this section carefully before instaling any supply lines.Since a suction
line leak is nearly impossibl to nd, take your time to assure all connections
are leak-free during instalation. Supply lines and ttings are furnished by the
installer.
With the vacuum gauge mounted on the pump vaccum port, the gauge will
indicate any suction line restriction, including a dirty lter.
A pump inlet maniford is suoolied for direct conecction of the lter to the inlet
of the pump.
All piping should be protected from possible damage and be rigidly fastened
in place in workmanlike manner.
NOTE: Care must be exercised to ensure leak-free connections.
G1 must be no farther than 5m from the supply tank and bottom of the supply
tank must be at least 1m higher then a burner, it is wery important that supply
line is at least 3/4“ or 1“ That is only way to obtain constant gravity-feeding of
G1 burner.

Applications:
• Heavy oil.
• One pipe and two pipes system.
• Self-priming.
• Manometer and vacuumeter connections.
• Capacity from 30 l/h to 140 l/h.
The suction vacuum generated by the gears
sucks up the fuel through the suction line “A”;
it crosses the lter and it is sent under pressure
to the pressure adjustment screw “RG”.
The fuel is sent to the nozzle at the pressure
value set by “RG”, only the exceding fuel is sent
on the return line “R”.
In the one-pipe system the by-pass screw
“B” is removed and the return “R” is pluged;
the whole fuel is sucked up by the gears without
crossing another time through the lter. During
the operation it is possible to measure the suc-
tion vacuum by the vacuum gauge port “V” and
the pressure by the pressure gauge port “P”; it is
also available on the pump an auxiliary delivery
port “P1”.
When the burner stops, instantly the pres-
sure comes down and the spring of the pressure
adjustment screw “RG” moves the piston which
stops the oil ow to the line and allows to the
uid to go through the return line “R”.
CONVERSION 2PIPES-1PIPESYSTEM
For the conversion proceed as follow:
• Remove the by-pass screw, located inside the
return port “R”.
• Lock the return port with a steel plug G 1/4
and washer
Heavy oil Burner Pump series PN
CHARACTERISTICS
ATTENTION:
In two-pipes system oil pump is self-priming, the bleding is obtained through the return line.
In one-pipe system the return line is closed by plug, the bleeding must be obtained through
the nozzle or opening the pressure gauge port “P”, to accelerate the way out of the air.

When setting into operation for the rst time, ll up the burner tank by hand
to the oil level mark.
When the oil level is too high, the oat switch switches off the burner auto-
matically. If the oil level is too low, the cartridge heater will be damaged.
Wait the burner will start automatically as soon as the fuel has reached the
right operation temperature.
Post regulation of oil consumption by the primary air regulator
Post regulation of smoke number and Co2 , by secondary air regulator
Optimum vlues: Smoke number as Bacharach “1” (max.”2”) Co2 - 10 to 11,5 %
WARNING: Turn off electric power to the unit before doing any service
or maintenance on the burner.
After more than 3 days out of operation: drain settled water and sludge
through drain tap in burner tank
Weekly:
Check the oil level in the supply tank to be certain that enough fuel is avail-
able. Inspect ame ring (clean it if necessary) and ignition electrodes (adjust
if necessary)
Monthly:
Clean pump strainer Remove the four bolts that hold the pump cover, (Be
careful, pump is full of oil) Be careful, not to lose or damage the gasket
and two O-rings (for pressure and vacuum) Remove the circular strainer and
clean it with a solvent and compressed air.
Clean photo cell.
Clean ignition electrodes and ame ring The electrode porcelain insulators
must be free from carbon, oil, dirt, cracks. Otherwise, short circuiting could
cause ignition problems.
Blow compressed air through nozzle and check ignition electrode distance
(drawing no. 02-16) NOTE: Be sure NOT to damage the O-ring on the noz-
zle. If the O-ring appears damaged, replace it.
Clean combustion chamber and ueway passages (on the boiler) from ash.
Drain settled water and sludge through drain tap in burner tank.
Yearly at begining + end of season
Carry out monthly servicing as described.
Clean catridge heater in burner tank and burner tank
