It
is
necessary
to
perform
periodic
maintenance
of
the

box
and
the
pan

.
The
cleaning
operations
must
be
carried

totally
cold
.
Should
residue
ashes
accidentally
remain
,
remove
with
a

cleaner.
With
the
aim
to
guarantee
to
the
customer
a
perfect
and
long
‐
lasting
running
,
we
have
limited
the
use
of

thus
limiting
the
possibility
of
undersigned
air
infiltration
within
the
combustion
chamber
which
could
cause
irregularities
in
the
combustion
process.
