It
is
computer
controlled
and

not
need
adjustment.
3.
Maintain
proper
space

easily.
Refer
to
p.
8,
p.9
and
p.

If
you
will
be
installing
the
unit
in
a
contaminated
area
with
a
high
level
of
dust,
sand,
flour,
aerosols
or
other
contaminants/chemicals,
they
can
become
airborne
and
enter
and
build
up
within
the
fan
and
burner
causing
damage
to
the
unit.
6.
Particles
from
flour,
aerosols,
and
other
contaminants
may
clog
the
air
vent
or
reduce
the
functions
of
the
rotating
fan
and
cause
improper
burning
of
the
gas.
Regularly
ensure
that
the
area
around
the
unit
is
dust
‐
or
debris
‐
free;
regular
maintenance
is
recommended
for
these
types
of
environment.

unit
where
the
exhaust
vent
is
pointing

may
disturb
your
neighbors.
Make
sure
the
vent
termination
meets
the
required
distance

from
entering
a
building
(refer
