The drain lines can be routed out the left or right side of the
furnace, but must maintain a downward slope to ensure
proper condensate drainage. The J-trap may need to be
rotated to the side that matches your setup. For 92.1%
series, see
Figure 36 (page 46) & Figure 37 (page 47).
For 95.0% series, see Figure 41 (page 51). To rotate
the J-trap, loosen the clamp on the drain tube, rotate the
J-trap to either side, and retighten the clamp.
