MINOR
PROPERTY
DAMAGE
Failure
to follow
this caution
may result
in minor
property
damage,
Local codes may reqnire
a drain pan under entire _rnace
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
for
fire, aces
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
instructions
_br these procedures
Step
2--Upflow
Applications
An upflow
t'tmlace application
is where
fm'nace
blower
is located
below
combustion
and controls
section of ffimace,
and conditioned
air is discharged
upwards
( ONDENSATE

The condensate
tlap is _hctory installed in the blower shell:"and
fhctory connected for UPFLOW applications. A factory-supplied
tube is used to extend the condensate trap drain connection to the
desired
furnace

NOTE:
See Fig. 6 or robe routing label on main furnace door to
confirm tocation of these tubes
l. ( ollector Box Drain, Inducer Housing Drain, Retief Port, and
Pressure Switch Tubes
These tubes are fhcto W attached to the condensate trap and
pressure switch ready _;oruse in UPFLOW applications. These
robes can be identified by their connection location and also
by a color label on each robe. These robes are identified as
£_llows: collector box &ain robe (blue label), inducer housing
&ain robe (violet label or molded), relief port robe (green
label), and pressure switch robe (pink label).
2. (ondensate
Trap Drain Tube
The condensate trap drain connection must be extended for
field attachment by doing the *%llowing:
a. Detemine
location of field drain connection. (See Fig. 2 or
6.)
NOTE:
If internal filter is used, drain robe should be located to
opposite side of casing from remm duct attachment to assist in
