Cleaning of painted parts
Do not clean the painted parts with wet rags when
the unit is in operation or hot to prevent thermal
shock to the paint which may cause it to detach.
Do not use abrasive or aggressive products or
materials. Clean with damp cotton or paper towels.
The silicon paints used by manufacturer possess
technical characteristics that make them resistent
to very high temperatures. There is however a
physical limit (380° C - 400° C) beyond which the
paint begins to fade or (over 450°) to vitrify; it may
then fl ake and detach from the steel surface. If this
happens, it means that temperatures have been
reached that are far above those at which the unit
should operate properly.
Do not use abrasive materials or
harsh. Clean with damp cotton or
paper towels.
Self-cleaning brazier cleaning
The boiler requires a simple and thorough cleaning
in order to ensure a more effi cient performance
and smooth operation. If your boiler is equipped
with a self-cleaning brazier, do not remove it during
cleaning. The brazier must be locked and cleaned
by an ash aspirator. Clean the brazier from the ash
and any rest with the appropriate tool. They could
obstruct the air passages. If the pellet in the tank
is exhausted, there might be a residual unburnt
pellets in the brazier. It's also important to clean
the ash accumulated inside of the combustion room
around the brazier. The frequency of this operation
depends on the use of the boiler.

Check every 60 days
Internal compartment cleaning
With the boiler off and cold, it is recommended
to open the front door and clean the combustion
chamber, the inside of the brazier and the lower
compartment where the ash accumulate with an
ash vacuum cleaner.
