IMPORTANT: There are two options
when choosing a height for the con-
densate riser:
CONDENSATE OVERFLOW: With a
5 1 ⁄ inch riser installed above the tee,

a blocked drain will result in overflow
from the riser.
FURNACE SHUTDOWN: To cause
the furnace to shut down when a
blocked drain is present, install a riser
which is a minimum of 10 13
furnace is installed in an attic, crawl-
space or other area where freezing
temperatures may occur, the furnace
drain can freeze while shut off for long
periods of time.
Use a solvent cement that is compati-
ble with PVC material. Cut the drain
hoses to the appropriate length and
connect to the trap with hose clamps.
Tighten the clamps with pliers and
check for leaks after attaching.
DOWNFLOW MODELS
IMPORTANT: There are two options
when choosing a height for the con-
densate riser:
CONDENSATE OVERFLOW: With a
1 3 ⁄ inch riser installed above the tee,

a blocked drain will result in overflow
from the riser.
FURNACE SHUTDOWN: To cause
the furnace to shut down when a
blocked drain is present, install a riser
which is a minimum of 5 1 ⁄ ". If the fur-

nace is installed in an attic, crawl-
space or other area where freezing
temperatures may occur, the furnace
drain can freeze while shut off for long
periods of time.
Use a solvent cement that is compati-
ble with PVC material.
REVERSING THE TRAP
UPFLOW MODELS
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 brack-
et to the right side with the drain
elbow pointing through the knockout.
Connect the 1 ⁄ " pipe and tee as noted
2
above. Route the drain hoses behind
the top of the electric box, cut to the
appropriate length, and connect to the
trap with hose clamps.
IMPORTANT: Do not connect into a
common drain line with an air condi-
tioner evaporator coil drain located
above the furnace. A blocked or
restricted drain line can result in over-
flow of the coil pan and negate the
furnace blocked drain shutoff control.
RXGY-H01
CONVERTING TO LEFT
DRAIN FOR DOWNFLOW
MODELS
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
pipe, a 2" rubber grommet, a 1-5/8"
⁄ ". If the
16
plug and instructions. Note the loca-
tion of the alternate drain hole as
shown in Figure 34.
To convert to left side drainage, first
remove the drainage hoses from the
trap. Remove the trap from its mount-
ing bracket, rotate it 180 degrees and
mount in place with the drainage
elbow pointing to the left. Reattach the
drain hoses.
Remove the plug from the 2" alternate
drain hole (see Figure 34) 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"

good seal in the burner compartment.

the pipe to the elbow in the trap. Cut
the pipe so that it extends through

plied 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 condi-
tioner evaporator coil drain located
above the furnace. A blocked or
restricted drain line can result in over-
flow of the coil pan and negate the
furnace blocked-drain shutoff control.
