WARNING
NOTE:
This furnace is shipped from the factory as a Dedicated Upflow.
A “Blocked Drain Kit” is available and
MUST BE USED
if the furnace
is installed Horizontal Left or Horizontal Right. Check the Serial/ Rating
Plate on the furnace for the Kit P/N.
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.
Make connections as follows:
1. Remove the rubber plug/cap from the coil 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 (end opposite the bend)
of Hose B. Save the part with the bend and discard the
17 3/4 inch piece that was cut.
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
taper) of each Tube 2. Save the 5 1/2” long pieces and
discard the pieces with the bends.
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.
9. A “Blocked Drain Kit” MUST be installed for right side down
installations. The kit includes a front cover pressure switch
that must be used to protect against a blocked drain
condition. Install the front cover pressure switch per the
instructions included with the “Blocked Drain Kit”. Failure to
install the “Blocked Drain Kit” will void the warranty and could
lead to bodily injury or death.
