5.1 PRELIMINARY CHECKS
BEFORE COMMISSIONING
Before commissioning the boiler, comply
with the following instructions:
– The system connected to the boiler should
be with open expansion tank system (fig.
9).
– The pipe connecting the boiler to the
expansion tank must have a suitable dia-
meter in compliance with the standards
in force.
– The heating pump must always run
during the boiler operation.
– The operation of the pump must never
be interrupted by an environment ther-
mostat.
– If the system is equipped with 3 or 4-way
mixing valve, this must always be opened
towards the system.
– Ensure that the draught regulator runs
regularly and there are no obstructions
that block the automatic operation of the
air gate dumper.
5.2 BOILER THERMOMETER
(fig. 11)
Indicates the temperature of the boiler
water (pos. 1).
5.3 AIR ADJUSTMENT (fig. 11)
The primary air is adjusted automatically by
means of a thermostatic valve; on the
other hand, the secondary air is adjusted
by means of a round port placed on the
upper side of the load port and must be
adjusted by the user.
At the first star t-up, the primar y and
secondary air must be adjusted, conside-
ring that the primary air determines the
boiler power and, therefore, the amount of
wood that is burnt and the secondary air
completes the combustion.
The optimal regulation of the
BPI-Eco ope-
ration is reached when both the boiler and
chimney will be "in temperature".
Depending on the wood used and its humi-
dity, rotate the round port (anti-clockwise
to open and clockwise to close) so to take
the flame to optimal conditions: orange-
pink-white with a blue centre.
CAUTION:
Secondary air regulator with high tempe-
ratures!
Use gloves or suitable equipment to not
get burned.
5.4 CLEANING (fig. 12)
Cleaning operations must be carried out
frequently, by cleaning, besides the flue
channels, also the ash-pit port, removing
the ash in the collecting tray.
For cleaning the flue channels, use a speci-
fic scraper.
5.5 MAINTENANCE
Do not per form any maintenance work,
dismantling or removal of parts without pro-
perly emptying the boiler first.
The boiler must not be emptied when the
water is hot.
CAUTION: The safety valve on the system
must be inspected by technically qualified
personnel in accordance with the laws of
the country of distribution and instruc-
tions for use of the safety valve.
If the system is completely emptied and
remains unused for some time, the safety valve
must be inspected before it is used again.
If the safety valve should malfunction and
cannot be re-calibrated, replace it with a
new 1/2” valve calibrated to 3 BAR and
conf or ming wit h Dir ective PED
97/23/CEE.
