13.3. MONTHLY MAINTENANCE
Remove any carbon deposit from the drafting fan impeller. Usually, with compressed air or a smooth
brush a perfect cleaning is achieved. If the deposits are sticked, we recommend anyway to be careful
with using more force to avoid unbalancing of the fan impeller which would become noisy and less
efficient.
Lubricate the front fan motor bearing.
13.4. EXTRA MAINTENANCE
13.5. EXPENDABLE MATERIALS
The grate bar elements are built with high temperature and smoke aggressive action resistant chrome cast
iron. Therefore, they are well suited for many hours of operation, whose number will depend upon the
average boiler working temperature which is determined by many other factors, such as the type of wood
most frequently used, its degree of humidity, the number and duration of the standby periods, etc.; how long
they will last depends as well upon the flame acidity degree, more or less accurate cleaning and
maintenance of the whole grate zone, if the boiler operates correctly within the standard parameters or not.
They are excluded from the warranty covering and must be considered from any point of view expendable
materials. The same considerations apply to the catalyst elements and the drafting fan.

At the end of each season a deep
cleaning operation must be
performed on the boiler, removing
any residual ash from the wood
chamber. If the boiler is not used in
the summertime keep the doors
closed.
Thoroughly clean the air
distribution subassembly, its
mounting place and the secondary
air passages removing pieces of
wood, tar and dust which may
have collected there during the
winter season operation.
Thoroughly clean all air passages
with a soft brush.
