WORKING FIELD

TBL 45P - TBL 60P - TBL 45P DACA - TBL 60P DACA
The working fields are obtained from test boilers corresponding to the standard EN267 and are indicatively for the combination burner-
boiler. For correct working of the burner the size of the combustion chamber must correspond to current regulations; if not the manufac-
turers must be consulted.
FUEL PIPE
This statement holds only if the required conditions exist (refer to
table of distances and difference in levels). To ensure an efficient
operation, it is better to make suction and return pipes with welded
fittings and to avoid the use of threaded connections which often
cause air infiltration's interfering with the pump operation and
consequently with the burner. Where a removable fitting is required,
use the welded flange method inserting a fuel resistant gasket to
obtain a positive sealing.
For systems requiring pipes with a relatively small diameter we
recommend the use of copper pipes. For unavoidable joints we
recommend the use of biconic fittings.
The annexed tables show the indicative diagrams for the different
types of systems depending on the position of the tank in respect
to the burner.
The suction pipe should run up-slope towards the burner to avoid
possible formation of gas bubbles. Where more burners are
installed in one boiler room, it is essential that every burner has its
own suction pipe. Only return pipes can lead to a single manifold
pipe with an adequate cross section leading to the tank. Never
connect the return pipe directly to the suction pipe.
It is a good practice to properly heat-insulate the suction and
return pipes to prevent cooling with would otherwise affect the
unit efficiency.
Pipe diameters (to be strictly complied with are listed in the
following table.
The maximum amount of vacuum that the pump can withstand
noiselessly under normal operating conditions is 0,47 bar; if
these limit is exceeded normal pump operation will no longer be
guaranteed.
Maximum suction and return pressure = 1 bar.
