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 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
hose clamp.
9. Insert short end of remaining Tube 2 into Hose B from
rubber elbow and secure with hose clamp.
Note: Ensure hoses and tubes maintain a downward slope
for proper drainage and are not kinked or binding.
For details concerning mounting of the drain trap, refer to
the following section.
Upright Drain Trap Mounting (Left or Right Side Panel)
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.
Note: Ensure hoses and tubes maintain a downward slope
for proper drainage and that they are not kinked or binding.
Horizontal Installations
Right Side Down
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 connec-
tion 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 condi-
tions. Cut hose to appropriate length to minimize sag-
ging. Plug left (unused) pressure tap with plug removed
from right side.
2. Secure Hose A to front cover drain tap with a hose
clamp. Route hose to rear right (down) side panel grom-
met holes.

down side panel grommet holes.
7. Cut 5 1/2 inches straight length from the long end of
each Tube 2.
8. Insert approximately one inch of each Tube 2 through
the right down side panel grommet holes. Secure tubes
to Hose A and Hose B using hose clamps.
Note: Ensure hoses and tubes maintain a downward slope
for proper drainage and are not kinked or bound.
For details concerning mounting of the drain trap, refer to
Condensate Drain Lines and Drain Trap - Upright Drain
Trap Mounting Left Side Down section.
