The working fields are obtained from test boilers corresponding to the standard EN267 and are indicatively for the combination
burner-boiler. For correct burner operation, the size of the combustion chamber must correspond to current regulations; if not, the
manufacturers must be consulted.

GAS SUPPLY LINE

The unit is equipped with a self-priming pump capable of sucking
oil directly from the tank also during the first fill-up. This statement
holds only if the required conditions exist (refer to table of distances
and difference in levels).
To ensure efficient operation, it is preferable to make intake and
return pipes with welded fittings and to avoid the use of threaded
connections which often cause air infiltrations and disturb pump
operation and consequently burner operation. Where a removable
fitting is required, use the welded flange method with a fuel resistant
gasket inserted to ensure a perfect sealing.
For systems requiring pipes with a relatively small diameter, we
recommend using copper pipes.
For unavoidable connections we recommend using "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 intake pipe should run up-slope towards the burner
to avoid the possible build-up of gas bubbles. Where more than one
burner is installed in one boiler room, it is essential that each burner
has its own intake 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 intake pipe.
It is advisable to properly insulate the intake and return pipes
to prevent cooling which would affect the unit's efficiency. Pipe
diameters (to be strictly complied with) are listed in the following
tables.
The maximum amount of vacuum that the pump can withstand
noiselessly under normal operating conditions is 0.47 bar; if this limit
is exceeded normal pump operation will no longer be guaranteed.
Maximum pressure at intake and return = 1 bar.
