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.

1. Remove the rubber plug from the coil front cover left (down)
side drain port.
2. Upflow furnaces
Relocate the front cover pressure switch hose connection
from the right side (as shipped) pressure tap to the left (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 right
(unused) pressure tap with plug removed from left side.
3. Secure Hose A to front cover drain port with a red hose clamp.
Route hose to rear left (down) side panel grommet holes.
NOTE: For left side drainage, grommets must be relocated
to left side panel.
