4.4 - OPERATION OF THE
BOILER
To ascertain that the form and the dimension
of the burner flame, which we estimate very
important, are the correct ones for the good
operation of the boiler, it is suggested to make
a visual inspection of the furnace at least one
month after the first lighting.
The furnace cylinder shall show a
homogeneous coloration for all of its length
to demonstrate that the flame reverses in
proximity of the blind bottom.
Contrarily, a furnace that underlines a clean
distinction of colour among two zones (the
anterior part clearer than the rear part), it
would be the typical example of a flame of
inadequate length, for which the adjustment
of the burner, to avoid located overheatings,
with consequent probable serious damages,
needs to be immediately revised.
Similarly, the state of the exchange surfaces
on the water side, where possible, i.e. on the
boilers beginning from the model ELL 1100,
standard equipped with inspection hand holes,
and in the case the presence of limestone,
sludges or deposits is found, the opportune
provisions to seek of it and to eliminate its
causes must be taken.
Such control must be effected within the first
months of exercise of the boiler, in any case
compulsorily to the first stop of the heating
system, at the end of the heating season or
on the occasion of standstills for other
extraordinary interventions, particularly in the
case of heating systems with large water
content.
The HIGH EFFICIENCY ELLPREX boilers
are forseen to operate with a return water
temperature never below 54 °C when operated
on light oil, and never below 59 °C when
operated on gas, to avoid (or, at least, to
reduce) the smoke acid condensation
phenomenon, which can be the reason of a
premature deterioration of the steel boiler
body. The working thermostat, pos. 32 of the
panel board, must be set at a temperature of
approximately 80 to 85 °C.
The room temperature will be compulsorily
adjusted through a mixing valve and,
eventually, an outer compensator.
To homogenise the water temperature, or
avoid as maximum as possible, returns into
the boiler at a temperature below 54 °C when
operated on oil, or 59°C when operated on
gas, a properly dimensioned shunt pump
must be fitted between flow and return pipes
of the boiler.
N.B.The metal sheet corrosion due to the acid
condensate is not covered by the
guarantee because it depends only from the
operation of the C.H. system.
The ELLPREX panel board is equipped with
a low temperature thermostat not allowing the
operation of the pump when the boiler
temperature is below 50 °C (protection against
cold starts).
4.5 - SWITCH OFF OF THE
BOILER
- Switch OFF the burner (switch No.12 to 0
position).
5.1 - GENERAL RULES
Before effecting any operation of cleaning or
maintenance, disconnect the boiler from the
electrical supply acting on the main switch
onto the panel board.
In case of failure or bad operation of the boiler,
switch it off, abstaining your self from any
attempt of reparation or direct intervention.
Exclusively address to professionally qualified
personnel.
The possible reparation of the boiler must be
effected by an authorized service center
using only original spare parts.
The non respect of the above can jeopardize
- Leave the pumps working up to when they
are not stopped by the minimum
thermostat.
- Switch Off the power to the boiler panel board.
MAINTENANCE
the safety of the boiler.
To guarantee the efficiency of the boiler and
for its correct operation it is essential to submit
the boiler to an annual maintenance, through
a professionally qualified technician, according
to the indications of the manufacturer.
When it is decided not to use the boiler
anymore, the parts which can be potential
sources of danger shall be made harmless.
After a month of boiler operation, open the
front door and ascertain the smoke pipes are
clean.
In case of a heavy dirtiness:
- Remove the turbulators from smoke pipes.
- Clean all the smoke pipes using the brush
delivered with the boiler.
- Open the two cleaning doors on the sides
of the smoke chamber and remove, with
a vacuum cleaner all the soot.
- Relocate the two cleaning doors and the
turbulators; then close the boiler front door
and check for soundness all around the
sealing rope.
- Then adjust the burner.
Note: With a burner properly adjusted only a
cleanup at the season end is necessary.

- If it is decided not to use the boiler for a
long period close also the gate valves of
the fuel.
5.2 - ORDINARY
MAINTENANCE
The boiler operating condition are very different
from one case to the other and depend on
the fuel used, on the adjustment of the burner,
on the number of starting, on the C.H. system
characteristics, etc. and for that reason it is
not possible to esthablish, in advance, the
frequence of the maintenances.
It is, then, necessary that the technician, who
performs the first cleaning, esthablish the
cleaning frequency on the base of the boiler
status.
Generally, we suggest the following frequency,
according to the fuel used:
- Gas fired boilers: once a year.
- Oil fired boilers: twice a year or more often
if there is reason to doubte of their
adjustment.
In any case the local rules in force have to
complied with.
We suggest to shake the turbulators, without
removing them from the smoke tubes, at least
once an month of operation, not to allow the
soot blocking them and making them extremely
difficult to be removed.
During the operations of ordinary maintenance
it will be necessary to brush the tube bundle
- after the removal of the turbulators - and
the furnace and collect the soots through the
