1. Insert drain tubes into drain trap and position the drain trap
against the side panel.

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 silver hose clamp. Angle tube outward toward front of
furnace.
5. Cut 17 3/4 inches from the long end (end opposite the
bend) of Hose B, discarding the 17 3/4 inch piece and
saving the part with the bend.
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 (end with
the taper) of each Tube 2. Save the 5 1/2 inch long pieces
and discard the pieces with the bend.
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.

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) 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.

4. Remove the rubber cap from the side drain port on the
rubber elbow.
5. Secure the short end of Hose B to rubber elbow side drain
port using a green hose clamp.
NOTE:
For left side drainage,
route hose to far left (down) side panel grommet holes.
NOTE:
Horizontal left side connections (when using new
side port drain elbow) does not require connecting a hose
to the induced draft blower housing.
6. Cut 5 1/2 inches straight length from the long end (end with
a taper) of each Tube 2. Save the 5 1/2 inch long pieces and
discard the pieces with the bends.
7. Insert approximately one inch of each Tube 2 through left
side panel grommet hole. Secure tubes to Hose A and
Hose B with a green hose clamps.
NOTE:
Tube must
reach bottom of trap. Ensure hoses and tubes maintain a
downward slope for proper drainage and that they are not
kinked or binding.
