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 right side of the 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 red hose
clamp. Route hose to rear right (down) side panel grom-
met 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 dis-
card.
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. En-
sure hoses and tubes maintain a downward slope for
proper drainage and are not kinked or bound.
