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 TRAP LO(ATION (FACTORY-SHIPPED
ORIENTATK)N)
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 side %r field drain attachment See Condensate
Trap Tubing (FactoQ--Shipped Orientation) section *%r drain tube
extension details. (See Fig. 6.)
CONDENSATE TRAP TL BING (FACTORY-SHIPPED
ORIENTATION)
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
filter removal.
