Downflow Vertical Furnace - The furnace is shipped
with the left side drainage setup. To change the right
side drain, remove the drain lines from the trap, rotate
the trap 180° so it exits to the right, reconnect the lines,
and run a 1/2" CPVC pipe from the trap out through the
right side knock-out. Use RTV silicone sealant to con-
nect the CPVC pipe to the trap for ease of removing to
clean the trap. See Figures 45 and 46.

HORIZONTAL APPLICATIONS
Upflow and Downflow Horizontal Furnaces - See
Figures 47 and 48. All horizontal applications are left side
only. It is always recommended that the auxiliary drain
pan be installed under a horizontally installed evaporator
and/or 95% Gas Furnace. Connect the auxiliary drain pan
to a separate drain line (no trap is needed in this line).

Use CPVC tubing from Trap outlet,
over burner box to cabinet exit
The furnace trap must be repositioned to the exterior of
the cabinet. Remove the trap from its present location
and reposition the trap outside of the unit, through the
long circular hole, next to the secondary recuperative
cell. Remove the larger drain line (from the secondary
cell) and trim to fit between the secondary cell and the
new trap location. On upflow units, plug the hole in the
blower deck where the tube went through with factory
supplied cap.
Remove the hose from the induced blower and reposi-
tion into the other drain tap of the inducer, which is lo-
cated 90° clockwise around the inducer. Move the cap
from that drain tap to the unused drain tap. On upflow
units, plug the hole in the blower deck where the tube
went through with factory supplied cap.
