BOILER START-UP

Manual fuel loading
In order to correct add fuel manually to the boiler follow the next steps:
Stop the fan function by pressing the STOP button. Wait 30 seconds for the fume to exit the
boiler.
Open the upper door slowly to avoid leakage of smoke. Load a sufficient amount of fuel. Each
loading should be regulated according to the boiler output and the heat demand. Never load
too much to fuel to fill all the fire chamber volume! Maximum fuel should be 70-80% of the
fire chamber volume.
Close the door and secure with the handle.
Start again the fan function by pressing the START button.
When loading fuel in the boiler do not throw them but position them carefully.

Operation mode
After firing the boiler up, switch the regulator to operation mode pressing "START" button in the
main window. In this mode, the fan operates in a constant manner with a preset airflow power
. However the feeder switches on cyclically for the TIME ON feeding time
per
TIME OFF feeding break time
.
After reaching the preset boiler temperature, the regulator automatically switches into the
SUPERVISION mode. After automatic return to the OPERATION mode, the feeder starts its cycles
from the OPERATION TIME OFF break time.

Combustion regulation
Biomass fuels vary significantly one from each other. For this reason, every time a different fuel
is used, the combustion regulation must be repeated.
For a correct combustion regulation you need to set first the fuel debit, by setting the TIME ON
and TIME OFF intervals of the feeder. The fuel must form a shape on the furnace plate according
to the following scheme:
In
order
to
increase the fuel debit you need to increase the TIME ON and decrease the TIME OFF. In order
to decrease the fuel debit, process is exact inverse. These two timings must be changed together
in order to have a constant flame.
During combustion, check the flame: it will have to occupy about two thirds of the fire chamber
and quietly lick the cylindrical heat exchanger. Its shape must be fully developed and with not
too many detachments at the flame end. Its color must be vivid orange-yellow, not too
transparent.
GENERAL SUGGESTIONS
The flame needs to have reasonable dimensions and fill up the fire chamber as told.
The flame must not be too red (too low air supply).
The flame must not have big detachments and sparkles (too high air supply).
The flame must not be too small. If it is slow, easily influenced by air currents and the chimney
draught, it means that the air supply is too low.
