APPLICATIONS

CAUTION
!
MINOR PROPERTY DAMAGE
Failure to follow this caution may result in minor property
damage.
Local codes may require a drain pan under entire furnace and
condensate trap when a condensing furnace is used in an attic
application or over a finished ceiling.
Step 1 - - General
Some assembly and modifications are required for furnaces
installed in any of the 4 applications shown in Fig. 1. All drain
and pressure tubes are connected as shown in Fig. 6. See
appropriate application instructions for these procedures.
Step 2 - - Upflow Applications
An upflow furnace application is where furnace blower is located
below combustion and controls section of furnace, and
conditioned air is discharged upwards.

CONDENSATE TRAP LOCATION
(FACTORY-SHIPPED ORIENTATION)
The condensate trap is factory installed in the blower shelf and
factory connected for UPFLOW applications. A factory-supplied
tube is used to extend the condensate trap drain connection to the
desired furnace side for field drain attachment. See Condensate
Trap Tubing (Factory-Shipped Orientation) section for drain tube
extension details. (See Fig. 5.)
CONDENSATE TRAP TUBING
(FACTORY-SHIPPED ORIENTATION)
NOTE: See Fig. 6 or tube routing label on main furnace door to
confirm location of these tubes.
1. Collector Box Drain, Inducer Housing Drain, Relief Port,
and Pressure Switch Tubes
These tubes should be factory attached to condensate trap
and pressure switch ready for use in UPFLOW
applications. These tubes can be identified by their
connection location and also by a color label on each tube.
These tubes are identified as follows: collector box drain
tube (blue label), inducer housing drain tube (violet label
or molded), relief port tube (green label), and pressure
switch tube (pink label).
2. Condensate Trap Drain Tube
The condensate trap drain connection must be extended
for field attachment by doing the following:
f. Determine location of field drain connection. (See
Fig. 2 or 6.)
NOTE: If internal filter is used, drain tube should be located to
opposite side of casing from return duct attachment to assist in
filter removal.
g. Remove and discard casing drain hole plug button
from desired side.
