7. Feed the 10” piece of soft tubing through
the round hole located in the right side of
the cabinet wrapper Note: A downward
slope must be maintained on the tube as
it is routed through the furnace (when the
furnace is in the horizontal position).
8. Assemble the 10” piece of soft tube to 5”
tall end of the hard (J) tube to the end of
the 10” soft tube located outside of the
furnace. Secure the connection using one
of the clamps that was removed, from the
“J” trap. Secure the connection with the 7/8”
hose clamp.
9. Reassemble the 30” piece of soft tubing
removed from the factory installed “J” tube
drain trap to the 2’ tall end of the modifi ed
“J” tube drain trap.
Note:
Ensure the clamps in step 7 and 8 are
securely tightened in order to avoid any con-
densate leakage.
Note:
PVC “T” drain assembly must be installed
so that condensate does not get into the induced
draft blower.( refer to Figure 2).
Note:
To avoid condensate freezing in the drain
trap assembly and tubing, insulate around the
drain trap assembly and all tubing located in
unconditioned space.

Conversion of the *TE Upfl ow Furnace for a
Horizontal Left Installation.
Refer to Figure 3.
1. Remove the hard “J” tube drain trap as-
sembly.
2. If fi eld supplied parts are used, disconnect
both soft tubes from the hard “J” tube drain
trap after loosing 7/8” clamps. Shorten long
side of the “J” trap by 8-1/2”.
3. Feed the 10” piece of soft tubing through
the round hole located in the left side of
the cabinet wrapper. Note: A downward
slope must be maintained on the tube as
it is routed through the furnace (when the
furnace is in the horizontal position).
4. Assemble the 5” tall end of the hard “J”
tube to the end of the 10” soft tube located
outside of the furnace. Secure the connec-
tion using one of the 7/8” hose clamps that
were removed from the “J” trap.
5. Assemble the 30” piece of soft tubing that
was removed from the “J” trap to the 2” tall
end of the modifi ed “J” drain trap. Secure
the connection with the 7/8” hose clamp.
NOTE:
To avoid condensate freezing in the drain
trap assembly and tubing, insulate around the
drain trap assembly and all tubing located in
unconditioned space.
NOTE:
When converting the
furnace, to horizontal left,
ensure that the drainage port
on the in-line drain assembly
is downward as shown in
this fi gure. If the in-line drain
assembly is not rotated, then
the furnace may not drain
properly.
