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 32.
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
2
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
1
kit includes a 24" piece of ⁄
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 33.
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.
Remove the plug from the 2" alternate
drain hole (see Figure 33) and
replace it with the 2" rubber grommet
supplied in the RXGY- H01 downflow
alternate drain kit. Also, remove the
1-5/8" grommet supplied in the
primary drain hole and replace it with
the 1-5/8" diameter plug that is also
supplied in the RXGY-H01 downflow
alternate drain kit. Both the hole-plug
and grommet must be in place to
insure a good seal in the burner
compartment.
A length of
provided in the RXGY-H01 downflow
alternate drain kit. Glue one end of
the pipe to the elbow in the trap. Cut
the pipe so that it extends through the
alternate drain hole in the left side of
the cabinet one inch (see Figure 33).
Connect the
with the furnace) to the pipe with a 1-
3/4" riser. Use the 1-5/8" plug
supplied in the RXGY-H01 downflow
alternate drain kit to seal the right side
drainage hole.
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.
To convert to left side drainage,
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 degrees and
mount in place with the drainage
elbow pointing to the left. Reattach
the long black molded hose. Use the
2-9/16" length of black hose included
in the RXGY-H01 kit between the trap
and exhaust transition. Clamp the
hoses tight with white nylon clamps.
FILLING THE TRAP
FILL THE TRAP ASSEMBLY WITH
WATER BEFORE OPERATING THE
FURNACE. Do this by removing the
drain hose from the trap or from the
connection to the secondary coil.
Pour about a cup of water into the
vent trap. Any excess water flows into
the house drain when the trap is full.
NOTE: Fill the trap assembly with
water every heating season.
