DRAINAGE OF CONDENSATE
FROM FURNACE
The condensate drainage system is internal to
the furnace. The drain may exit either the right or
left side of the furnace cabinet. For a right side
drain simply extend the tubing out of the 7/8"
hole in the cabinet, see Figure 21.
For a left side drain follow the steps below:
1. Loosen the clamp on the soft exit tube (see
Figure 21.)
2. Rotate the soft exit tube (counter clockwise,
180° upflow G6RC/RD models; clockwise
90° downflow G6RL models.)

3. Re-tighten the clamp. MAKE SURE CLAMP
IS TIGHT TO AVOID LEAKAGE OF CON-
DENSATE.
4. Route the tubing out of the 7/8" hole located
8 inches up from the bottom furnace.
The condensate should drain from the plastic
collector box (location A in Figure 21) as droplets
or a small stream. If you notice the furnace has
operated for more than 5 minutes without drain-
ing or the red status light on the control board is
pulsing a 2-blink code follow the steps below.
1. Remove the collector box soft tube at loca-
tion A in Figure 21 and insure the exit from
