5.3 REGULATION OF COMBUSTION AIRS IN ASPIROMEC LE AND ASPIROTRONIC LE
5.4 REFUELLING WITH WOOD
5.5 ADJUSTMENT OF THE COMBUSTION AIR DAMPER OPENING
To regulate the airs firstly remove the guard with the writing ASPIRO-
TRONIC on it (there is no guard on the ASPIROMEC model).
1- Act on damper 1 to regulate the intake of primary combustion air.
The correct position should be 1/3 of its stroke. If the opening is
bigger then there is an increase in power in the firebox.
2- Act on damper 2 to regulate the intake of secondary combustion
air. The correct position should be 1/3 of its stroke; it must always
be less than the primary air.
If not, the power is not supplied correctly.
The correct position for this damper guarantees optimal efficiency
and low emissions. If the load of wood is placed on a bed of embers
thicker than 5 cm the primary air does not flow freely. In these
conditions the boiler only operates on the secondary air.
The result is a reduction of power.
REFUELLING THE ASPIROMEC LE BOILER WITH WOOD
- Before opening the loading door make sure that the red light on the panel is not on.
If it is on (automatic fuel finished device shuts off the fan) the boiler has to be started up again by turning
the main switch off and on (the fan restarts at the maximum power).
- Open the loading door and lower the baffle plate.
- Use a riddling tool to spread out the embers and remaining wood uniformly (the height must not exceed
5 cm; if it does, the power is limited).
- Arrange the wood uniformly on the burner plate and make sure that there are as few gaps as possible
between the pieces of wood.
REFUELLING THE ASPIROTRONIC LE BOILER WITH WOOD
- Before opening the loading door make sure that the smoke suction unit is not operating at low capacity
and that it is not stopped. If it is press the H.H. button on the panel; the suction unit starts to function at
maximum capacity for a time of 1 minute.
- Open the loading door and lower the baffle plate.
- Use a riddling tool to spread out the embers and remaining wood uniformly (the height must not exceed
5 cm; if it does, the power is limited).
- Arrange the wood uniformly on the burner plate and make sure that there are as few gaps as possible
between the pieces of wood.
On the ASPIROMEC LE and ASPIROTRONIC LE boilers the damper
must remain closed when the fan is not working.
If the flue outlet, creating an excessive draft, does not satisfy
the above condition, then adjust the draft control flap by acting on the
counterweight screw (1). If necessary,
bend the shaft by hand as well.
