CAUTION
!
FURNACE OPERATION HAZARD
Failure to follow this caution may result in furnace damage.
Special precautions MUST be made when installing
furnace. The condensate pipe with the float switch can not
be obstructed or used to directly drain the coil drain pan.
This can cause improper operation or damage to equipment.
The float switch must NOT be obstructed.

NOTE: PVC pieces must be glued using PVC glue to prevent
leaks.
Upflow Specific Steps – Offset Installation
1. Install short CPVC tubes (Fig. 15 or Fig. 17). The longer
tube (Tube A) should be installed in the upper most rubber
elbow. Torque the clamps to hand- -tight (15 lb- -in.). Over
tightening hose clamps may crack plastic components
which may result in water leaks and possibly water damage.
2. Remove adhesive backing from the Collar Gasket and apply
it to the rear side of the Collar Plate.
3. Place Collar Plate over condensate drain knockout while
routing the short CPVC tubes through the Collar Plate.
4. Using six (6) of the sheet metal screws, screw the Plastic
Collar to the furnace casing.
5. Remove two (2) blower shelf screws and install the Adapter
Plate. Using two (2) of the sheet metal screws provided,
attach the Upflow Bracket to the Adapter Plate (Fig. 17).
6. Assemble the Tubes (C, D, & E) and Elbows (45° & 90°)
using PVC glue and connect to Tubes A & B (Fig. 17).
Ensure the two long tubes are pointed downward before
glue is set.
7. Set the Trap Assembly on the arms of the bracket and
tighten with the provided bolt and nut. Ensure the bottom of
the large Tee is resting on the bracket (Fig. 18).
8. Tighten remaining two (2) clamps connecting Tubes A & B
to the Rubber Elbows (Fig. 15). Torque the clamps to hand- -
tight (15 lb- -in.). Over tightening hose clamps may crack
plastic components which may result in water leaks and
possibly water damage.

Horizontal Specific Steps
1. Install and tighten remaining two (2) clamps and two (2)
long CPVC tubes (Fig. 15 and Fig. 21). Torque the clamps
to hand- -tight (15 lb- -in.). Over tightening hose clamps may
crack plastic components which may result in water leaks
and possibly water damage.
2. Remove adhesive backing from the Collar Gasket and apply
it to the rear side of the Collar Plate.
3. Slide the Plastic Collar approximately halfway up the tubes
and then slide the Trap Assembly over the long CPVC
tubes. You may need to push the long CPVC tubes towards
the back of the furnace during this step depending on the
clearance below the furnace (Fig. 21).

4. Using six (6) of the sheet metal screws, screw the Plastic
Collar to the furnace.
5. Insert the Trap Assembly onto the Plastic Collar (Fig. 22).
Using two (2) sheet metal screws, fasten the condensate trap
assembly to the Plastic Collar.

(Note: Drain line can be run horizontally or vertically)
NOTE: Field Supplied Drain can be routed horizontally from
tee at top of the trap, allow at least 1/4- -in. per foot of slope
down.
Extra water in transducer pressure tubing may inhibit furnace
operation because of incorrect pressure readings.
6. Remove collector box cap.
7. Remove transducer pressure tubing and trim transducer
pressure tubing length ensuring no traps or loops for extra
water collections. Install on the port where the collector box

cap was removed from (Fig. 14).
