6. FURNACE
IN
HORIZONTAL RIGHT POSITION
A CAUTION
Both the
coil
and
furnace
must
be
fully
supported. Do
not
attempt
to
suspend
the
coil
using
only
the brackets.
The
non-condensing furnaces
may
be
laid
on
either
side for
horizontal application.
The
condensing downflow/horizontal
and
upflow/horizontal
furnaces
may
not
be
rotated
onto
their
right
side.
Connection
brackets
for coil/furnace
alignment
are
included
with
the
furnaces.
a. Horizontal right:
For
the
horizontal
right
configuration
in
non-condensing furnaces only,
the
two-piece factory
baffle
must
be removed
and
the
top baffle replaced for
the
following models: 4TXCB004, 4TXCC005, 4TX-
CC006,
4TXCC007,
and
4TXCC008.
b. Replacing
the
factory
installed
baffle.
1. Remove
the
factory
installed
two-piece baffle assem-
bly (see
Figure
4) from
the
apex
of
the
coil
by
removing
the
5/16"
hex
head
screws. Discard
the
bottom
half
of
the
baffle.
2. Replace
the
top baffle
using
the
screws removed
previously (see
Figure
8).
3.
Figure
9 shows
the
baffle change
necessary
for hori-
zontal
right
application.
IMPORTANT:
The 4TXC cased
coil
must
be
placed
downstream
of
the
furnace, with the apex
of
the
coil
always
pointing
opposite
the direction
of
the
airflow
for
horizontal
right
installation.
This placement supersedes previous furnace Installer's
Guide stating
install
"with the apex
of
the
coil
pointing
in
the direction
of
airflow
for
horizontal application." See
Figure
10.

c.
When
the
noncondensing Upflow/Horizontal furnace
is
placed
on
its
right
side for
right
airflow,
the
furnace top
flange
meets
the
cased coil top flange.
The
coil flange
fits inside
of
the
furnace flange. See
Figure
11.
There
are
three
holes
in
the
furnace top flange which
can
be
used
for pilot holes to connect
and
align
the
furnace
and
coil.
There
are
self
drilling screws included
which
can
be
used
for
this
connection.
Seal
all
gaps
between
the
furnace
and
coil.
