hose to Tube 1 with a green hose clamp. Route other end
of Hose B to front left side panel grommet hole.
6. Insert short end of each Tube 2 through side panel grommet
holes. Secure tubes to Hose A and Hose B with green hose
clamps. Ensure hoses and tubes maintain a downward slope
for proper drainage and that they are not kinked or binding.

ONNECTIONS
Upright installations using the alternate vent/flue outlet will require
“right-side only” drain hoses to be connected as follows. Refer to
Section IX, Vent/Flue Pipe and Combustion Air Pipe for details on
alternate vent/flue pipe connection.
1. Remove the rubber plug from the front cover right-side drain
port. Save for use in step 3.
2. Secure Hose A to front cover drain port with a red hose clamp.
Route hose to rear right side panel grommet hole.
3. Remove grommet from front right-side panel drain hole. Seal
hole in grommet with large end of plug. Reinstall grommet
and plug into side panel drain hole.
4. Cut 1/4 inch from the end of the drain port on the externally
mounted rubber elbow. Discard cut portion.
5. Insert Tube 1 into rubber elbow drain port and secure with a
red hose clamp. Angle tube outward toward front of furnace.
6. Cut 17 7/8 inches from the long end of Hose B and discard.
7. Secure remaining end of Hose B to exposed end of Tube 1
with a green hose clamp. Route hose toward right side panel
grommet holes.
8. Insert short end of one Tube 2 through rear right side panel
grommet drain hole. Secure tube to Hose A with a green
hose clamp.
9. Insert short end of remaining Tube 2 into Hose B from rubber
elbow and secure with green hose clamp. Ensure hoses
and tubes maintain a downward slope for proper drainage
and are not kinked or binding.

1. Insert drain tubes into drain trap and position the drain trap
against the side panel. NOTE: Drain tubes must reach the
bottom of the drain trap.
2. Secure drain trap to side panel at the mounting holes (dimples
or crosshairs on counterflow models) located below the
grommet drain holes.
3. Attach PVC drain line to drain trap outlet with either a 90°
elbow or coupling.

Horizontal installations with the right side down require that the drain
hoses be connected to the right side front cover drain port and the
rubber elbow drain port.
NOTE: On counterflow models, relocation of the front cover pressure
switch hose is required.
Make connections as follows:
1. Remove the rubber plug from the coil front cover drain port.
Counterflow furnaces
Relocate the front cover pressure switch hose connection
from the left side pressure tap to the right (down) side tap.
The pressure switch hose must be connected to the down
side to guard against blocked drain conditions. Cut hose to
appropriate length to minimize sagging. Plug left (unused)
pressure tap with plug removed from right side.
2. Secure Hose A to front cover drain tap with a red hose clamp.
Route hose to rear right (down) side panel grommet holes.
3. Cut 1/4 inch from the end of the drain port on the rubber
elbow and discard.
4. Insert Tube 1 into rubber elbow drain port and secure with a
red hose clamp. Angle tube outward toward front of furnace.
5. Cut 17 3/4 inches from the long end of Hose B and discard.
6. Secure remaining end of Hose B to exposed end of Tube 1
with a green hose clamp. Route hose to front right down
side panel grommet holes.
7. Cut 5 1/2 inches straight length from the long end of each
Tube 2.

Horizontal installations with the left side panel down will require drain
hoses to be connected to the left side front cover drain port and the
side drain port on the rubber elbow.
1. Remove the rubber plug from the coil front cover left (down)
side drain port.
2. Relocate the front cover pressure switch hose connection
from the right side (as shipped) pressure tap to the left (down)
