Upright Drain Trap Mounting—Left or Right
Side Panel
1. Insert the drain tubes into the drain trap and position the
drain trap against the side panel.
NOTE: Drain tubes must reach the bottom of the drain trap.
2. Secure the drain trap to the side panel at the mounting holes
(dimples or crosshairs on counterflow models) located below
the grommet drain holes.
3. Attach the PVC drain line to the drain trap outlet with either a
90° elbow or coupling.
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/cap from the right side of the front
cover drain port.
NOTE: On counterflow furnaces, relocate the front cover
pressure switch hose connection from the left side pressure
tap to the right (down) side tap to guard against blocked drain
conditions. Cut the hose to appropriate length to minimize
sagging. Plug the left (unused) pressure tap with the plug
removed from right side.
2. Secure Hose A to the front cover drain tap with a red hose
clamp.
3. Route Hose A to the rear right (down) side panel grommet
holes.
4. Cut ¹⁄₄" (6.4 cm) from the end of the drain port on the
externally mounted rubber elbow. Discard cut portion.

NOTE: Angle tube outward toward front of furnace.
6. Cut 17³⁄₄" (45.1 cm) from the long end of Hose B. Discard cut
portion.
7. Secure the remaining end of Hose B to exposed end of Tube
1 with a green hose clamp.
8. Route Hose B to the front right (down) side panel grommet
holes.
9. Cut 5¹⁄₂" (14 cm) straight length from the long end of each
Tube 2. Discard the radius pieces.
10. Insert approximately 1" (2.5 cm) of each Tube 2 through the
right (down) side panel grommet holes.
11. Secure the tubes to Hose A and Hose B using the green hose
clamps.
NOTE: Ensure that the hoses and tubes maintain a
downward slope for proper drainage and are not kinked or
bound.
For details concerning the mounting of the drain trap, refer to
"Horizontal Drain Trap Mounting" in "Condensate Drain Lines and
Drain Trap."

Horizontal Installations—Left Side Down
Horizontal installations with the left side panel down will require
the 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/cap from the 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)
side tap.
NOTE: The pressure switch hose must be connected to the
down side to guard against blocked drain conditions. Cut the
hose to the appropriate length to minimize sagging. Plug the
right (unused) pressure tap with the rubber plug removed
from the left side.
3. Secure Hose A to the front cover drain port with a red hose
clamp.
4. Route Hose A to the rear left (down) side panel grommet
holes.
NOTE: For left side drainage, grommets must be relocated to
the left side panel.
