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.
For details concerning mounting of the drain trap, refer to the fol-
lowing section.

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.

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.
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 green hose clamps. Ensure hoses and
tubes maintain a downward slope for proper drainage and
are not kinked or bound.
