OPTIONAL EQUIPMENT
OPTIONAL CONDENSATION DRAIN FOR DUCT FURNACES
Model SCE furnaces are certified for installation upstream or downstream from a cooling coil. When installed
downstream from a refrigeration system, condensation will form and, therefore, adequate provision must be made
to dispose of condensate.
Periodic cleaning of the condensate collection and disposal system is required. Install the drain connection, option
CS1 (PN 31765), on the furnace casing as shown in Figure 32.

Figure 32. Optional Condensate Drain Connection
Terminate the drain outside the building. Provide a trap to prevent air from entering the combustion zone. Periodic
cleaning of the condensate collection and disposal system is required.
NOTE: Requires a four-inch (102 mm) minimum clearance under the furnace if a 90-degree
street elbow is used.
