Manufacturer’s declaration
We hereby declare that our gas, light oil, heavy oil, and combination (gas/light oil or gas/heavy oil)
burners are manufactured in conformance with current CE, CEI and UNI standards.
• BALTUR guarantees the “CE” certification provided that the burner is coupled to the “CE” gas train
supplied by BALTUR and the “CE” gas line accessories (on request).
NOTE: this declaration is not valid with regard to EC or UNI Standards for gas burners or the gas part of
duel-fuel burners (gas/light oil or gas/heavy oil) when such burners have been ordered in non-compliance
with the EC Standard or Italian UNI Standard because they are to be used for special purposes not provided
for in the above-mentioned standards.
L' Amministratore delegato
Dott. Riccardo Fava
· Read carefully the instructions before starting the burner and service it.
· The works on the burner and on the system have to be carried out only by competent people.
· The system electric feeding must be disconnected before starting working on it.
· If the woeks are not carried out correctly it is possible to cause dangerous accidents.

FUEL FEED PLANT
The burner pump must receive fuel from a suitable feed circuit including an auxiliary pump with pressure adjustable
from 0,5 to 2 bar, pre-heated at 50 - 60 °C.
Fuel feed pressure value to the burner pump (0,5 ÷ 2 bar) must not vary both when the burner is not operating and
when the burner is in operation at the maximum fuel output level requested by the boiler.
The feed circuit must be built according to our drawings n° BT 8511/6 or n° BT 8513/7 also when using low viscosity-
fuel.
Pipe dimensions must be in relation to their length and to the delivery of the pump used.
Our instructions only concern everything necessary to ensure good operation.

2 - Insulating gasket
3 - Burner fixing flange
4 - Stud bolt
5 - Locking nut with washer
Remarks
When tightening the flange, it is important to do it evenly so that the inner faces are parallel between them.
Since the locking system is highly efficient, do not tighten the nuts too much.
During this operation (tightening of the flange locking nuts) keep the body of the burner lifted so that the
combustion head is kept in a horizontal position.
Remarks
The burner is correctly installed when the pre-heating tank is slightly inclined (higher on the side where fuel exits
to go to the nozzle).
This inclination serves to prevent gas from building up inside the tank.
Presence of gas in the pre-heating tank will greatly increase the time required to pressurise the fuel, and it is quite
likely that the burner will go into “block”.
Be careful when installing the burner on the boiler that the burner is not positioned where it cancels this inclination
or, even worse, where the pre-heating tank is sloping in the opposite direction to the direction desired.
