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
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 blower shelf by gently pushing tabs inward and rotaing trap.
3.Remove casing hole filler cap from casing hole. (See Fig. 2 and 10.)
4.Install casing hole filler cap
!WARNING
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.
5.Install condensate trap into
6.Fill unused condensate trap casing holes with plastic filler caps
