Instructions
Direct
Unit
Mounting
The
previous
directions
are
the
preferable
way
to
mount
the
new
rear
grill.
The
unit's
performance
is
slightly
better
and
the
possibility
of
draughts
is
reduced.
As
a
last
resort,
direct
mounting
of
the
grille
to
the
unit
can
be
considered.
Note:
The
grille
must
be
installed
prior
to
inserting
the
unit
into
the
sleeve.

the
rear
of
the
unit
making
sure
that:

set
of
screw
holes
are

the
bottom.
b.
The
fins
of
the
grill
are
pointed
away
from
the
unit.
3.
Align
the top
of
the
grille
with
the
top
of
the
unit.
The
overhang
on
each
side
is
equal.
4.
If
the
unit
has
not
been
pre-drilled
(some
models),
carefully
drill 4

1/8”
holes
through
the
grille
and

the
side
flange
of
the
unit
