(dimples or crosshairs on counterflow models) located
below the grommet drain holes.

Horizontal Connections - Left Side Down
(Upflow Shown, Counterflow Similar)
NOTE: On counterflow models, relocation of the front cover
pressure switch hose is required. The pressure switch hose
must be connected to the bottom port of the collector box
cover to guard against blocked drain conditions. Cut hose to
appropriate length to minimize sagging. Install the rubber plug
on the open port.
Make connections as follows:
1. Remove the rubber plug/cap from right side of the front
cover drain port.
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 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 and discard the radius pieces.
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.
For details concerning mounting of the drain trap, refer to Con-
densate Drain Lines and Drain Trap - Horizontal Drain Trap
Mounting.
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.
