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 black molded 90°
hose
➂
from the top of the
existing trap
➂
and from the
furnace collector box. Cut 1.0
inch from the straight end of the
hose.
NOTE:
Exception–do not
shorten the 90° hose on the 07B
furnace! The 07B has a longer
distance between the collector
box and the horizontal drain trap.
4. Remove the double-elbow black
molded hose
➂
from the exhaust
transition
➂
. Discard this hose
and the downflow trap. 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. Attach the gasket
➇
onto the trap
assembly so that the gasket
holes on the gasket line up with
the holes on the trap assembly.
7. Fill the trap assembly
➆
with a
cup of water.
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
to the straight spout
on the trap top using a white
nylon clamp
. Attach the other
end of the rubber elbow to the
spout
located on the exhaust
transition
using a white nylon
clamp.
