DOWNFLOW APPLICATIONS
A downflow furnace application is where furnace blower is
located above combustion and controls section of furnace, and
conditioned air is discharged downwards.
Condensate Trap
Location
The condensate trap must be removed from the factory --installed
blower shelf location and relocated in selected application
location as shown in Fig. 2, 9, or 10.
To relocate condensate trap from the blower shelf to desired
location, perform the following:
1. Remove three tubes connected to condensate trap.
2. Remove trap from b lower shelf by gently pushing tabs in-
wardandrotatingtrap.
3. Remove casing hole filler cap from casing hole. (See Fig.

CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal
injury or death.
Casing hole filler cap must be installed in blower shelf hole
when condensate trap is relocated to prevent combustion
products being drawn in from appliances in the equipment
room.
