REVERSING THE TRAP
UPFLOW UNITS
The trap may be moved to the right
side for right side drainage. Open the
knockout for the drain on the right
side of the cabinet. Remove the
bracket holding the trap from the left
side. Seal the left side drain hole with
a plug provided in the cloth bag with
the furnace. Position the mounting
bracket and trap so that the drain
elbow is centered in the hole on
the right. See Figure 33.
Drill two holes in the cabinet to mount
the bracket. Mount the trap and
bracket to the right side with the drain
elbow pointing through the knockout.

Connect the / -in. pipe and tee as

noted above. Route the drain hoses
behind the control box, cut to the
appropriate length, and connect to the
trap with hose clamps.
IMPORTANT: DO NOT ALLOW ANY
SAGS OR KINKS IN THE HOSES.
This prevents proper condensate
flow.
IMPORTANT: Do not connect into
a common drain line with an air
conditioner evaporator coil drain
located above the furnace. A blocked
or restricted drain line can result in
overflow of the coil pan and negate
the furnace blocked drain shutoff
control.

DOWNFLOW UNITS
To convert downflow models to left-
hand drain, a kit (RXGY-H01) must
be ordered from the distributor. The
kit includes a 24" piece of 1/2" black
PVC pipe, a 2-9/16" length of black
hose, a 2" rubber grommet, a 1-5/8"
plug and instructions. Note the
location of the alternate drain hole as
shown in Figure 34.
First remove the long molded hose
from the trap. Remove the double-
elbow black molded hose from the
trap and exhaust transition and
discard. Remove the trap from its
mounting bracket, rotate it 180°, and
mount in place with drainage elbow
pointing to the left. Reattach the long
black molded hose. Use the 2-9/16"
length of black hose included in the
kit between the trap and exhaust
transition. Clamp the hoses tight with
white nylon clamps.
