PROPERTY
DAMAGE
Failure
to follow
this caution
may result
in minor
property
damage.
Local codes may require
a drain pan under entire filmace
and
condensate
trap when a condensing
furnace
is used in an attic
application
or over a finished
ceiling.
APPLICATIONS
Step
l--General
Some
assembly
and
modifications
are
required
%r
furnaces
installed
in any of the 4 applications
shown
in Fig. 1. All &ain and
pressure
robes are connected
as shown
in Fig
6 See appropriate
application

Step
2--Upf[ow
Applications
An upflow
furnace
application
is where
t_mnace blowei
is located
below
combustion
and controls
section of f_./rnace, and conditioned
air is discharged
upwards.
CONDENSATE
TRAP LOCATION
(FACTORY-SHIPPED
ORIENTATION)
The condensate
tlap
is flactol-y installed
in the blower
shelf
and
fhctory
connected
for UPFLOW
applications
A factoo-supplied
tube is used to extend the condensate
trap drain
connection
to the
desired
t'urnace
side for field drain
attachment.

NOTE:
Failure
to use CPV(

LO(ATION
(ALTERNATE
LPFLOW
ORIENTATION)
An alternate
tocation
fbr d-le condensate
t_ap is the left=hand
side
of casing.
(See Fig
2 and 7)
NOTE:
If the alternate
left°hand
side of casing
location
is used.
the fimtolT°connected
&ain and relief port tubes must be discon-
nected
and modified
for attachment.
See Condensate

section
for tubing

To relocate
condensate
tlap
to the left-hand
side,
perfbm_
the
following:
1. Remove
3 tubes connected
to condensate
trap.
2. Remove
trap ti"om blower
shelf by gently
pushing
tabs inward
and rotating
trap.
3. Install
casing
hole filler
cap (factory=supplied
in loose parts
bag) into blower
shelf hole where
trap was removed.

Failure
to £dlow
this warning
could
result in personal

be installed
in blower

is relocated
to prevent
