CONDENSATE DRAIN
FOR HORIZONTAL
INSTALLATION
Refer to Figure 35 for Steps 1-4.
This unit is shipped factory ready for
downflow installation. The
condensate trap assembly and drain
hoses require conversion for
horizontal installation. Remove the
existing condensate trap with the unit
in the upright position.
1. Remove the burner compartment
door from the unit.
2. Remove the two screws from the
right side of the furnace jacket
which support the trap mounting
bracket.
Remove the two
plastic plugs on either side of the
trap outlet hole and discard.
3. Remove the (L-shaped) clear
vinyl drain tube
➂
from the top of
the existing trap
➀
.
Do not disconnect the short end
from the furnace collector box.
4. Remove the ribbed drain tube
➃
from the existing trap
➀
and the
exhaust transition
➄
. Discard this
tube. Retain the clamps for future
use. Additional clamps are
provided in the parts bag if any
clamps are damaged during
conversion process.
NOTE: The following steps should
take place with the furnace in the
horizontal position.
Refer to Figure 36 for Steps 6-11.
5. Locate the parts bag in the
burner compartment. Install two
plastic plugs
➅
in the side of the
jacket from bottom side up.
6. Fill the trap assembly

➇
onto the trap
assembly so that the gasket
holes on the gasket line up with
the holes on the trap assembly.
8. Insert the trap assembly with
gasket up through the existing
hole in the jacket and secure
from inside the jacket. Use two
screws provided. Screw down
into the two “ears” molded into
either side of the trap. Snug the
trap assembly against the
furnace jacket compressing the
gasket slightly to eliminate any
air leaks. Do not overtighten!
9. Attach the black molded rubber
90° elbow
➈
to the straight spout
on the trap top using a black
nylon clamp
➉
. Attach the other
end of the rubber elbow to the
